DAYS 1-5 (MAY 31 – JUNE 4)

A transition from the feel of summer to the feel of earlier spring takes place today as we see a strong back-door cold front, which has already reached the NH Seacoast as of 7 a.m., power its way southwestward across the WHW forecast area during the morning and early afternoon today, and by the end of the day the entire region will be immersed in a maritime polar air mass. After this, the boundary sits just to our southwest while a weak disturbance passes by tonight from northwest to southeast, a stronger one follows it up later Wednesday, and yet another comes along Thursday night into Friday. This points to an unsettled first 3 days of June for our region, with the wettest periods most likely being Wednesday PM & Friday AM, leaving a good part of Thursday rain-free – however don’t expect much sun at all, other than some limited amounts today. Finally by Saturday, a stronger push of dry air from eastern Canada will clear us out to start the weekend.

TODAY: Partial sun, then mostly cloudy. Chance of drizzle eastern coastal areas by late-day. Highs 68-75 NH Seacoast and Cape Ann / Cape Cod MA and 75-82 elsewhere this morning, falling thereafter to 56-63 by late-day. Wind shifting to NE 5-15 MPH with higher gusts from northeast to southwest across the region this morning after starting out W up to 10 MPH.

TONIGHT: Cloudy. Areas of drizzle and fog, especially near the coast. Isolated to scattered showers and thunderstorms possible, mainly evening. Lows 51-58. Wind NE 5-15 MPH, higher gusts possible near the coast early.

WEDNESDAY: Cloudy. Areas of drizzle and fog, especially near the coast. Scattered to numerous showers and thunderstorms, mainly late afternoon. Highs 55-62. Wind E 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Chance of showers. Patchy drizzle/fog. Lows 51-58. Wind SE up to 10 MPH.

THURSDAY: Mostly cloudy. Highs 62-69, coolest South Coast. Wind variable up to 10 MPH.

THURSDAY NIGHT: Mostly cloudy. Chance of showers, especially overnight. Patchy fog. Lows 55-62. Wind variable up to 10 MPH.

FRIDAY: Mostly cloudy. Showers likely, favoring the morning and midday. Patchy fog. Highs 63-70, coolest coast. Wind variable to N up to 10 MPH.

FRIDAY NIGHT: Clouds break evening. Clearing overnight. Patchy fog early. Lows 52-59. Wind N 5-15 MPH.

SATURDAY: Sun and passing clouds. Highs 71-78. Wind N 5-15 MPH.

DAYS 6-10 (JUNE 5-9)

High pressure should continue a fair weather weekend through June 5. Potential unsettled period June 6-8 with a frontal boundary nearby. Additionally, during this time we’ll likely be watching a low pressure area, originally of tropical origin but transitioning or transitioned to post-tropical, passing to our south without impact other than stirred up ocean waves, but its worth watching with with normal uncertainly this far out. High pressure should return with fair weather to end this period June 9.

DAYS 11-15 (JUNE 10-14)

A weak westerly flow should be the dominant pattern and we may find ourselves near a boundary between cool air to the north and warmer and more humid air to the south. This could increase chances of periodic shower activity but at this point it doesn’t look like a change to a wet pattern. No extremes of temperature expected into mid June.

C-19 Chat Post – 5-31-2022

Memorial Day 2022 … Remembering all who paid the ultimate sacrifice. Never forget them.

DAYS 1-5 (MAY 30 – JUNE 3)

Many Memorial Day parades and services will take place across the area this morning – some of them in their full form for the first time since 2019. The weather could not be better as we’ll have sunshine, mild to warm air, and fairly low humidity, as well as not too much wind, just a gentle breeze. For people in uniform and some spectators, it may be a bit warm in the sun, especially by late morning, so hydration and as much shade as possible will benefit. We won’t be in a situation with high heat and humidity that would accelerate those potential problems, at least. Today’s weather will be governed by high pressure which is centered to our south, and high pressure aloft overhead, which ensures the fair and dry, warm conditions. There will be some high cloud patches from time to time coming down in a northwesterly air flow aloft due to the ridge axis sitting just to our west. It’ll also be a great day for other outdoor activity – walks, cookouts, pool, beaches, although the latter two come with a reminder that any unheated pools and rivers/lakes/ocean are likely to still have water that is quite cold, and that one needs to exercise caution and limit time when going in water. It’s also a big road traffic day for many returning from early-season visits to their favorite places, and while we’ll probably see heavier than normal traffic on the highways especially later today, at least there won’t be any weather-related problems. Tomorrow, we end the month of May anticipating the arrival of a back-door cold front. My best guess on the timing of this feature is that it arrives via the Gulf of Maine making its first impact on the NH Seacoast and Cape Ann MA as early as 8 or 9 a.m., Boston about an hour after that, then across the remainder of the WHW forecast area from northeast to southwest so that by late afternoon, everybody has lost the warm air mass, is in a cool marine air mass, and has at least considerable low cloudiness if not a complete stratus overcast. Areas of fog and drizzle will develop especially by Tuesday evening and night, favoring areas closer to the eastern coastline, but some penetrating inland as well. Wednesday, the first day of June, will remind you more of the middle of April, with temps that may hang in the 50s, an east wind, not too strong but noticeable enough especially if you are near the shore, and in the soup of clouds with patchy fog/drizzle. The frontal boundary just to our south and west will make a feeble attempt to push back this way as a warm front Wednesday night and Thursday, but will likely be thwarted by high pressure too strong to the north and a wave of low pressure moving eastward along the boundary, pulling it back to the south somewhat by Friday. An additional wave of low pressure may cause more showers Friday as well. So we have an unsettled first 3 day s of June coming up, and ironically we may receive very little in the way of any beneficial rain to help with our precipitation deficit and early drought conditions in some areas.

TODAY (MEMORIAL DAY): Mostly sunny to partly cloudy. Highs 79-84 coast, 85-90 inland. Wind SW to W 5-15 MPH.

TONIGHT: Partly cloudy. Lows 60-67. Wind SW up to 10 MPH.

TUESDAY: Partly cloudy start, then becoming mostly cloudy from northeast to southwest. Chance of drizzle near eastern coastal areas by late in the day. Highs 78-85, but turning much cooler from northeast to southwest starting mid morning / midday. Wind W 5-15 MPH shifting to NE.

TUESDAY NIGHT: Mostly cloudy. Areas of fog and drizzle, especially near the coast of NH and eastern MA. Lows 51-58. Wind NE 5-15 MPH.

WEDNESDAY: Mostly cloudy. Chance of drizzle with areas of fog especially near the eastern coast. Highs 55-62, coolest coast. Wind E 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Chance of showers. Patchy drizzle/fog. Lows 52-59. Wind SE up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of showers. Highs 68-75, coolest South Coast. Wind SE up to 10 MPH.

THURSDAY NIGHT: Mostly cloudy. Chance of showers. Lows 55-62. Wind NE up to 10 MPH.

FRIDAY: Mostly cloudy. Chance of showers. Highs 63-70, coolest East Coast. Wind NE-N up to 10 MPH.

DAYS 6-10 (JUNE 4-8)

Optimistic for a push of cool to mild, dry air from Canada for the June 4-5 weekend with fair weather. High pressure builds in during this time then shifts to the southeast with a frontal boundary likely nearby with some unsettled weather chances during the June 6-8 period. During a portion of the DAYS 6-10 period we may see an early season tropical system crossing somewhere near Florida then moving into the Atlantic but the early indications are that system would stay well to the south and move out over open water.

DAYS 11-15 (JUNE 9-13)

A weak westerly flow should be the dominant pattern and we may find ourselves near a boundary between cool air to the north and warmer and more humid air to the south. This could increase or shot at periodic showers which could help alleviate the dryness we’ve been experiencing. But I’m far from sold on this idea at this point. Either way, I don’t see it being overly cool or overly warm to hot either – just kind of seasonable.

DAYS 1-5 (MAY 29 – JUNE 2)

No need to waste time reading a long blog on the first of two beautiful holiday weekend days, so here’s an abbreviated synopsis and forecast update for southeastern New England. A high pressure ridge will be the upper level dominator of our weather for the last few days of May. Surface features will determine our sensible weather. High pressure to the south of the region will bring two dry days today and Memorial Day with a warm-up. A back-door cold front will sweep into the region during Tuesday from the northeast capping the warm up and reversing the temperature trend. When we get to midweek, June arrives with a cooler spell and a deterioration in the weather as the front that came through starts to make a return toward the region with an increase in clouds and eventually the chance of some wet weather with the break-down of ridging and arrival of a disturbance from the west.

TODAY: Mostly sunny. Highs 74-79 coast, 80-85 inland. Wind NW under 10 MPH early, becoming variable, then SE up to 10 MPH especially coast.

TONIGHT: Mostly clear. Lows 56-63. Wind S to SW up to 10 MPH.

MONDAY (MEMORIAL DAY): Mostly sunny to partly cloudy. Highs 79-84 coast, 85-90 inland. Wind SW to W 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 60-67. Wind SW up to 10 MPH.

TUESDAY: Partly sunny. Highs 78-85, but turning much cooler from northeast to southwest starting midday or afternoon. Wind W 5-15 MPH shifting to NE.

TUESDAY NIGHT: Variably cloudy. Lows 51-58. Wind NE 5-15 MPH.

WEDNESDAY: Partly sunny. Highs 66-73, coolest coast. Wind NE to E 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Lows 53-60. Wind E up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of showers. Highs 65-72. Wind SE up to 10 MPH.

DAYS 6-10 (JUNE 3-7)

Frontal boundary nearby – unsure if our region ends up on the warm side briefly, but at least a chance of some shower activity on June 3 with this. Canadian air mass brings drier, cool air June 4-5. Warmer air tries to make a come-back with some unsettled weather possible later in the period.

DAYS 11-15 (JUNE 8-12)

Overall pattern looks fairly dry and seasonable to slightly cooler than normal with predominant flow from eastern Canada at the surface.

C-19 Chat Post – 5-29-2022

DAYS 1-5 (MAY 28- JUNE 1)

The Memorial Day Weekend has arrived and there are no surprises to report today since the outlook posted yesterday. We have our unsettled day today as we sit in a mild and muggy air mass ahead of a cold front, which will pass by this evening. One round of showers and embedded thunderstorms crosses parts of the region in the pre-dawn hours. The next round of activity will be triggered by the approach and arrival of the cold front this afternoon and evening. The strength of any storms will be determined by how much clearing can take place to destabilize the atmosphere, and right now it looks like that clearing may be limited, with the most sunshine taking place well north and west of Boston. That factor, along with the limiting factor of ocean influence from a south southwest wind in eastern MA, eastern CT, and RI, even southeastern NH, will limit the chance of any stronger storms getting into the majority of the WHW forecast area. However, since there are many outdoor activities planned and ongoing today as part of the holiday weekend, it’s essential to keep a close eye on the evolution of any showers and storms from afternoon to evening. Once that front goes by the region, any lingering activity will move out and/or dissipate and we’ll transition to a drier air mass overnight. High pressure settles in, its center to the southwest and south of our region, to give us a fair and warm Sunday and Monday, salvaging most of the weekend with great conditions for any outdoor activity. Monday will end up the warmest day. Tuesday will be an interesting day regarding the temperature, as this depends on the timing of a back-door cold front that will be coming down from via the Gulf of Maine. Currently, I favor timing that allows us to quickly warm up in the morning, followed by a big cool-down in southeastern NH and eastern MA during the day, spreading further south and west later in the day and at night, with the marine air mass over the entire region when we get to Wednesday, the first day of June and meteorological summer. I don’t think any rainfall will accompany the back-door front, just some clouds, which may hang around at times into Wednesday, although the air will be dry enough to allow sunshine too.

TODAY: Mostly cloudy but also some intervals of sunshine at times. Scattered showers/thunderstorms this afternoon, favoring areas north and west of Boston. Any storms could be strong, especially southern NH and central to northeastern MA. Highs 71-78, coolest South Coast. Humid – dew point 60+. Wind SSW 5-15 MPH, higher gusts.

TONIGHT: Clouds break. Evening fog patches. Humidity lowers. Lows 55-62. Wind SW 5-15 MPH shifting to NW.

SUNDAY: Mostly sunny. Highs 74-79 coast, 80-85 inland. Wind NW under 10 MPH early, becoming variable, then SE up to 10 MPH especially coast.

SUNDAY NIGHT: Mostly clear. Lows 56-63. Wind S to SW up to 10 MPH.

MONDAY (MEMORIAL DAY): Mostly sunny. Highs 79-84 coast, 85-90 inland. Wind SW to W 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 60-67. Wind SW up to 10 MPH.

TUESDAY: Partly sunny. Highs 78-85, but turning much cooler from northeast to southwest starting midday or afternoon. Wind W 5-15 MPH shifting to NE.

TUESDAY NIGHT: Variably cloudy. Lows 51-58. Wind NE 5-15 MPH.

WEDNESDAY: Partly sunny. Highs 66-74, coolest coast. Wind NE to E 5-15 MPH.

DAYS 6-10 (JUNE 2-6)

Wave of low pressure passing northwest of the region brings the boundary that went by previously back as a warm front with clouds/showers June 2. Difficult timing but cold front swings through with a shower/t-storm threat June 3 when it may be briefly warm and humid. Cooler thereafter with a Canadian air mass arriving. Warm air trying to make a comeback may increase the cloud cover later in the period but overall pattern is still dry.

DAYS 11-15 (JUNE 7-11)

Overall pattern looks fairly dry and seasonable to slightly cooler than normal with predominant flow from eastern Canada at the surface.

DAYS 1-5 (MAY 27-31)

Memorial Day Weekend’s weather is the center piece of this 5-day discussion. This marks the “unofficial” start of the summer season, as far as tourism and vacationing goes. And for many it starts with a “getaway day” today, which is not really going to present any real weather-related challenges for our area unless you are going to be traveling during tonight. During the day we’ll just be contending with a lot of cloudiness as a warmer and more moist southerly air flow becomes established, and any precipitation will be limited to a quick sprinkle of rain mainly to the west or a patch of drizzle near the South Coast. Tonight, a surface trough will approach and then move through in the early morning hours of Saturday from west to east. While this feature will be approaching our area with a healthy batch of good coverage showers and thunderstorms, it looks like it loses a lot of support so that the activity will have diminished to scattered while it moves through the WHW forecast area and mostly gone by shortly after dawn. The next threat of showers and thunderstorms does not come until the approach and passage of a cold front later Saturday, so this leaves us with several hours especially morning and midday that are free of rain threat and may even feature some intervals of sunshine, making Saturday a non-washout and salvaging part of the day for any outdoor plans, so long as you are wise and keep an eye on the radar. Afternoon shower and thunderstorm activity will probably be scattered as opposed to widespread, but any storms that do form and move into the area can be strong with even an isolated severe storm possible, so if you are traveling or do have outdoor plans please keep this in mind and have a plan to move to shelter if needed. The cold front pushes through by early Saturday night and sets us up for a spectacular and somewhat summery Sunday and Monday. The air won’t really be all that cool behind that “cold” front because its source region is not particularly chilly and the center of high pressure will be passing to our south, allowing a west to southwest wind to warm us up on those days. Tuesday presents the next forecast dilemma as we see that high to the south sliding further away and a bubble of high pressure in eastern Canada become stronger. Inevitably, the boundary between the two plays into our forecast as is typical for spring in New England, and we’ll be trying to determine the timing of the arrival of a back-door cold front from the northeast. This boundary has a high impact on Tuesday’s temperatures for our region. With this being day 5 right now, I’m going to play the middle ground, start us warm, then cool the region down with a PM frontal passage. If the front is sooner, we cool more quickly … later, and we keep the warmth through most of or all of the day. But for those who are taking an extra long weekend and may be returning to the area on Tuesday, the weather itself should not be an issue as again it looks like dry weather holds.

TODAY: Mostly cloudy – intervals of sun at times. A sprinkle possible southwestern NH, central MA, and eastern CT during the afternoon along with a potential patch of drizzle near the South Coast. Increasingly humid – dew point rising to or a little over 60. Highs 66-73 coast, 73-80 inland. Wind S 10-20 MPH.

TONIGHT: Mostly cloudy. Chance of showers, possibly a thunderstorm. Patchy fog. Humid – dew point upper 50s to lower 60s. Lows 58-65. Wind S to variable up to 10 MPH.

SATURDAY: Mostly cloudy but also some intervals of sunshine at times. Showers possible near dawn. Scattered showers and thunderstorms in the afternoon, some of which can be strong. Areas of fog early. Highs 70-77, coolest South Coast. Humid – dew point 60+. Wind SW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Clouds break, but fog patches remain. Humidity lowers. Lows 55-62. Wind SW 5-15 MPH shifting to NW.

SUNDAY: Sun/cloud mix. Highs 75-82, coolest coast. Wind W 5-15 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 56-63. Wind SW up to 10 MPH.

MONDAY (MEMORIAL DAY): Partly sunny. Highs 80-87, cooler South Coast. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 60-67. Wind SW up to 10 MPH.

TUESDAY: Partly sunny. Highs 78-85, but may turn much cooler from northeast to southwest by late-day. Wind W 5-15 MPH shifting to NE.

DAYS 6-10 (JUNE 1-5)

Iffy temperature / weather forecast in here due to a lot of weather players on the field in close proximity. Looks like we stay on the cooler side of the aforementioned front for June 1 with dry and pleasant weather, then the boundary moves back as a warm front with a shower threat on June 2, followed by a cold front from the west with a shower/t-storm threat June 3, then fair weather for the June 4-5 weekend with high pressure in control.

DAYS 11-15 (JUNE 6-10)

Overall pattern looks fairly dry and seasonable to slightly cooler than normal with predominant flow from eastern Canada at the surface.

C-19 Chat Post – 5-27-2022

DAYS 1-5 (MAY 26-30)

Today’s discussion will be a quick one to summarize the features in control of our weather from today through the upcoming Memorial Day Weekend. Tomorrow I’ll expand a little bit more to detail the final 5 days of May… Warmer air is making its way in aloft and that’s the reason for the cloudiness we’ll have around today – but these clouds are not going to produce any rainfall in our area, so overall it will be a nice day. You’ll notice the humidity creeping up tonight and especially on Friday as we get into a stronger southerly air flow ahead of an approaching trough of low pressure and associated surface low which will drag a warm front through the region late Friday with a round of showers and a few possible thunderstorms, but the greater risk of showers and storms comes with a trough early Saturday morning and then again with a cold front Saturday afternoon – the timing of these we will have to fine-tune in the next 2 days. This means that the holiday weekend gets off to an unsettled start, but there is good news as it looks like high pressure builds in to salvage 2 of the 3 days, with fair weather for Sunday (removed shower threat) and Monday.

TODAY: Variably cloudy. Highs 67-74, coolest coast. Wind SE-S 5-15 MPH.

TONIGHT: Mostly cloudy. Lows 58-65. Wind S 5-15 MPH.

FRIDAY: Mostly cloudy. Chance of showers, favoring western areas late in the day. More humid – dewpoint cracking 60. Highs 66-73 coast, 73-80 inland. Wind S 10-20 MPH.

FRIDAY NIGHT: Mostly cloudy. Chance of showers, possibly a thunderstorm. Patchy fog. Humid. Lows 58-65. Wind S to variable up to 10 MPH.

SATURDAY: Mostly cloudy. Episodes of showers and possibly thunderstorms, favoring early morning and sometime afternoon / evening. Areas of fog early. Highs 68-75. Dew point 60+. Wind SW 5-15 MPH.

SATURDAY NIGHT: Clouds break, but fog patches remain. Humidity lowers. Lows 55-62. Wind SW 5-15 MPH shifting to NW.

SUNDAY: Sun/cloud mix. Highs 68-75, coolest coast. Wind N to E up to 10 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 51-57. Wind E to variable under 10 MPH.

MONDAY (MEMORIAL DAY): Partly sunny. Highs 75-82, coolest coast. Wind variable to SE up to 10 MPH.

DAYS 6-10 (MAY 31 – JUNE 4)

The heat potential is there for May 31 and/or June 1 but odds are starting to favor one or even both of those days seeing that thwarted by a back-door cold front and cooler maritime air, at least over eastern parts of the region. After that, the fair and warmer pattern may try to take hold but we will still have to watch for maritime influences. No sign of any significant rainfall, which we need, and this will allow our dry / early drought to expand.

DAYS 11-15 (JUNE 5-9)

Overall pattern looks fairly dry and seasonable to slightly warmer than normal.

C-19 Chat Post – 5-26-2022

DAYS 1-5 (MAY 25-29)

The meteorological process today takes me a little deeper into deciphering the mystery that is predicting the future, and now 2 of the 3 days that comprise Memorial Day Weekend will be in this DAYS 1-5 forecast period. Recalling recent tremendous disagreement among major medium range guidance, the process started with acknowledging that both solutions were likely overdone, and that reality likely lies somewhere between solutions. Since then, there’s been a little more agreement developing between the various models, although they are not quite “there” yet. But this leads me to further investigation based on what I know of model bias as it relates to the current and upcoming weather pattern.What I am confident of is that today will be a fairly nice day as high pressure, albeit weak, governs our weather. Coolest air will again be felt along the coast – typical for this spring set-up. High pressure shifts offshore tonight and Thursday and a warm front quietly goes by, with Thursday daytime featuring a varying amount of clouds but also some sunshine, mild to warm air, but still dry in terms of humidity. It is on Friday and Saturday when we will see the humidity spike up, but with the approach of a trough of low pressure and a surface low pressure area and frontal system, our chance of wet weather will go up too. The current idea is that the shower threat during the daytime hours of Friday will be mostly to the west of the WHW forecast area, but expand into the region at night, and then Saturday is the day that is likely to at least start with occasional showery weather. If we manage to get a wave of low pressure that sits to our south, as some guidance has suggested, we could end up with an onshore flow and a general overcast with drizzle and showers that persists more of the day. Some guidance pushes the system offshore a little more steadily and allows for drying to take place later on in the day, and I am cautiously optimistically leaning toward this scenario, but not completely losing the shower threat. In fact, I think there will still be enough influence from low pressure that we can see a pop up shower on Sunday too, but that the day overall will feature improvement over Saturday with a little more sunshine and lower humidity. With the importance of the forecast for this unofficial start of the summer season upcoming, I’ll continues to monitor and make any forecast adjustments needed, but for now this is how it looks.

TODAY: More sun than clouds. Highs 65-72, coolest coast. Wind variable teo SE up to 10 MPH.

TONIGHT: Variably cloudy. Lows 50-57. Wind SE under 10 MPH.

THURSDAY: Partly sunny. Highs 67-74. Wind SE-S 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Lows 58-65. Wind S 5-15 MPH.

FRIDAY: Mostly cloudy. Chance of showers, favoring western areas late in the day. More humid – dewpoint cracking 60. Highs 66-73 coast, 73-80 inland. Wind S 10-20 MPH.

FRIDAY NIGHT: Mostly cloudy. Chance of showers, possibly a thunderstorm. Patchy fog. Humid. Lows 58-65. Wind S to variable up to 10 MPH.

SATURDAY: Mostly cloudy. Chance of showers. Areas of fog and drizzle. Humid – dew point 60+. Highs 65-72, cooler coast. Wind variable up to 10 MPH, may become E.

SATURDAY NIGHT: Clouds break, but fog patches remain. Humidity lowers. Lows 55-62. Wind variable to S up to 10 MPH.

SUNDAY: Cloud/sun mix. A pop up shower possible. Highs 68-75, coolest near the coast. Wind SE up to 10 MPH.

DAYS 6-10 (MAY 30 – JUNE 3)

If things follow the scenario I expect, then Memorial Day Monday would be a fair weather day with warmer inland temperatures but a cooler coastal sea breeze. After that building high pressure offshore could provide a taste of summer heat again for the final day of May. After that there are signs that high pressure drops down from eastern Canada with fair and somewhat cooler weather to start June, but a warm-up by late in the period as the high settles to the south. Obviously days 6-10 leave a fair amount of uncertainty on the table. As we wrap up meteorological spring, barring a heavier rainfall than forecast for the end of this week, we are going to end the March through May period in the top 10 as far as dry weather goes. Meteorological spring’s driest occurred in 1915 with only 3.50 inches of rain for Boston, with 1910, 1981, and 1927 coming in at #’s 2, 3, and 4, with 4.49 inches, 4.93 inches, and 4.95 inches, respectively. (Info from NWS via WBZ Meteorologist Eric Fisher.) At 5.84 inches of rain for March, April, and May-to-date, Boston sits at 8th driest with just a handful of days left to go.

DAYS 11-15 (JUNE 4-8)

A weak blocking pattern may try to establish itself but the overall weather pattern remains on the dry side with no extremes of temperature.

C-19 Chat Post – 5-25-2022

DAYS 1-5 (MAY 24-28)

High pressure will be in control of our weather today through Wednesday, first centered to our north then slipping down over and eventually southeast of our area, so today will be the cooler and breezier of the two days with a northeasterly wind. We’ll also see periodic higher level cloudiness from abundant moisture to our south. With a low pressure trough approaching from the west and high pressure offshore of the Atlantic Coast we get into a more southerly air flow Thursday and Friday, with a warming trend, but also a fair amount of cloudiness at times too. We may not end up seeing much rainfall around here though as it looks like a lot of that will remain to our west. This is a slower evolution than some guidance had yesterday and this lends a little more credibility to the more unsettled weather scenario as we head into the Memorial Day Weekend – a forecast that still needs a lot of work. For now though, I’m leaning toward an unsettled Saturday to start it off, with lots of clouds and some wet weather, but probably not a widespread rainfall either, though we finally get the trough of low pressure and frontal boundary right into our region.

TODAY: Cloud/sun mix. Highs 58-65 immediate coast, 65-72 inland. wind NE 5-15 MPH, gusts around 20 MPH.

TONIGHT: Mostly clear. Lows 38-45 interior valleys, 45-52 elsewhere. Wind NE under 10 MPH to calm.

WEDNESDAY: Partly sunny. Highs 65-72, coolest coast. Wind variable to SE up to 10 MPH.

WEDNESDAY NIGHT: Variably cloudy. Lows 50-57. Wind SE under 10 MPH.

THURSDAY: Partly sunny. Highs 65-72. Wind SE-S 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Lows 58-65. Wind S 5-15 MPH.

FRIDAY: Mostly cloudy. Chance of showers. More humid. Highs 66-73 coast, 73-80 inland. Wind S 10-20 MPH.

FRIDAY NIGHT: Mostly cloudy. Chance of showers, possibly a thunderstorm. Patchy fog. Humid. Lows 58-65. Wind S to variable up to 10 MPH.

SATURDAY: Mostly cloudy. Chance of showers. Areas of fog and drizzle. Humid. Highs 65-72, cooler coast. Wind variable up to 10 MPH.

DAYS 6-10 (MAY 29 – JUNE 2)

The forecast for the remainder of the Memorial Day Weekend (May 29-30) is low confidence but for now leaning toward just a chance of a few showers around on Sunday and improving but cooler weather Monday with more of an onshore air flow as high pressure to the north pushes low pressure away to the south. End May / early June should feature fair and seasonably mild weather with weak high pressure in control.

DAYS 11-15 (JUNE 3-7)

Early June pattern continues to look like it will be somewhere between weak zonal flow and weak omega blocking with us on the drier side of the pattern overall, along with mostly seasonable temperatures.
