DAYS 1-5 (JUNE 16-20)

As we count down the final days of spring and arrive at summer on the final day of this 5-day forecast block, we’ll continue to undergo a transition from pleasantly cool weather to warmer and more humid conditions. Still looking at a dry pattern in terms of rainfall, however, with the only risk being an isolated shower or thunderstorm that may pop up in the heat and humidity on Saturday.

TODAY: Mostly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

TONIGHT: Mostly clear. Lows 50-57. Wind SE under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 70-77 coast, 77-84 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 55-62. Wind SE-S under 10 MPH.

THURSDAY: Mostly sunny. More humid. Highs 75-82 coast, 83-90 inland. Wind S 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Humid. Lows 60-67. Wind S up to 10 MPH.

FRIDAY: Mostly sunny. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Humid. Lows 62-69. Wind SW up to 10 MPH.

SATURDAY: Partly cloudy. Isolated afternoon showers or thunderstorms possible. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 21-25)

Watching for a potential back-door cold front that could make it considerably cooler and potentially mostly cloudy as well for June 21. If this front does not threaten the region, the weather that day would be similar to the day before it. Warm/humid with a risk of showers / t-storms from approaching front June 22. That front may provide a rare risk for a period of rain from late June 23 into June 24 after which dry weather would be back.

DAYS 11-15 (JUNE 26-30)

A zonal (west to east) flow is expected with variable but overall seasonably warm weather but limit opportunities for any shower activity as the overall pattern continues dry.

DAYS 1-5 (JUNE 15-19)

High pressure will continue to dominate the weather through the next 5 days during which time we will see a transition from cool easterly air flow to warm and more humid southerly air flow. By late week, areas away from the coast will be feeling the heat of summer, while temperature remain more modified along the shoreline.

TODAY: Low clouds in much of the region and patchy fog near the coast into mid morning then becoming sunny. Highs 65-70 coast, 70-75 inland. Wind E 5-10 MPH inland, 10-15 MPH coast.

TONIGHT: Clear except patchy ground fog interior lower elevations. Lows 48-55. Wind E under 10 MPH.

TUESDAY: Mostly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 50-57. Wind SE under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 68-75 coast, 75-82 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 55-62. Wind SE-S under 10 MPH.

THURSDAY: Mostly sunny. More humid. Highs 75-82 coast, 83-90 inland. Wind S 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Humid. Lows 60-67. Wind S up to 10 MPH.

FRIDAY: Mostly sunny. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 20-24)

Higher humidity, southerly air flow, and a risk of isolated showers / t-storms June 20. Watching for a potential back-door cold front that could make it considerably cooler and potentially mostly cloudy as well for June 21. Warming back up with a risk of showers / t-storms from approaching front June 22. That front may provide a rare risk for a period of rain from late June 23 into June 24. Low confidence forecast at this time.

DAYS 11-15 (JUNE 25-29)

A more zonal (west to east) flow is expected with variable but overall seasonably warm weather but limit opportunities for any shower activity as the overall pattern continues dry.

DAYS 1-5 (JUNE 14-18)

High pressure will continue to dominate the weather through the next 5 days. Its center to the north initially will continue to result in a general easterly flow, and there should be enough low level moisture for a deck of stratus clouds to roll in from the ocean tonight into Monday morning, at least over eastern sections, especially coastal areas. Most of this should burn off during Monday, however. That’s really the only interruption on a long stretch of fair weather with low humidity and below average temperatures.

TODAY: Partly sunny. Highs 62-67 coast, 67-72 inland. Wind E up to 10 MPH.

TONIGHT: Mostly cloudy. Lows 49-56. Wind E under 10 MPH.

MONDAY: Mostly cloudy morning. Mostly sunny afternoon. Highs 63-70, coolest coast. Wind E up to 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 48-55. Wind E under 10 MPH.

TUESDAY: Mostly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 50-57. Wind SE under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 68-73 coast, 73-78 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 53-60. Wind SE under 10 MPH.

THURSDAY: Mostly sunny. Highs 70-75 coast, 75-80 inland. Wind SE-S 5-15 MPH.

DAYS 6-10 (JUNE 19-23)

High pressure will have shifted to a position east of New England by late in the coming week with an increase in humidity and warmth June 19-21. Generally dry weather is expected overall, but isolated showers may pop up during the June 20-21 weekend with more significant daytime heating occurring. Look for a better chance of showers/thunderstorms June 22 as a front pushes into the region, then drier air arrives for the end of the period.

DAYS 11-15 (JUNE 24-28)

A transition to a more zonal (west to east) pattern, but may be marked with a rare episode of wet weather around June 24. Drier weather follows with temperatures warming to more seasonable levels, but significant heat probably not occurring as the ridge axis is likely to be too far west for that.

12:44AM

DAYS 1-5 (JUNE 13-17)

This one’s easy. High pressure will sit over southeastern Canada and the northeastern US for the next 5 days. With its center north to northeast of the region, a general easterly air flow will dominate, starting out a bit northeasterly this weekend then shifting more southeasterly toward the middle of next week. This set-up prevents significant heat and also keeps humidity generally low. A negative aspect is the lack of beneficial rain. Our rainfall deficit continues to increase and watering will be essential for development of crops and maintenance of flower gardens. Brush fire danger will also be running above normal.

TODAY: Mostly sunny. Highs 65-70 coast, 70-75 inland. Wind NE up to 10 MPH.

TONIGHT: Mostly clear. Lows 48-55. Wind NE under 10 MPH.

SUNDAY: Partly sunny. Highs 62-67 coast, 67-72 inland. Wind E up to 10 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 46-53. Wind E under 10 MPH.

MONDAY: Mostly sunny. Highs 63-70, coolest coast. Wind E up to 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 48-55. Wind E under 10 MPH.

TUESDAY: Mostly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 50-57. Wind SE under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 68-73 coast, 73-78 inland. Wind SE up to 10 MPH.

DAYS 6-10 (JUNE 18-22)

High pressure slips further southeast, to east of New England, with more of a southerly air flow resulting. This will increase the warmth and humidity gradually heading toward the end of this week, and with a little more moisture from the south and an approaching frontal boundary from the west, we’ll see a risk of some shower and thunderstorm activity especially during the second half of the period (June 20-22).

DAYS 11-15 (JUNE 23-27)

A transition to a more zonal (west to east) pattern, but may be marked with a rare episode of wet weather around June 24. Drier weather follows with temperatures warming to more seasonable levels.

7:35AM

DAYS 1-5 (JUNE 12-16)

High pressure gives a cold front a final push offshore this morning and then the high is basically the dominant force in our weather for the next 5 days, holding low pressure to the south at bay. We may see some cloudiness at times, but despite some torrential downpours associated with yesterday’s humidity and approaching front, this remains a dry pattern overall.

TODAY: Clouds and showers, a few heavy, lingering over Cape Cod & The Islands until mid morning followed by clearing there. Mostly sunny to partly cloudy elsewhere. Less humid. Highs 78-85. Wind SW up to 10 MPH.

TONIGHT: Mostly clear. Lows 53-60. Wind NW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 67-72 coast, 73-78 inland. Wind NE up to 10 MPH.

SATURDAY NIGHT: Mostly clear. Lows 48-55. Wind NE under 10 MPH.

SUNDAY: Partly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

SUNDAY NIGHT: Variably cloudy. Lows 52-59. Wind E under 10 MPH.

MONDAY: Partly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

MONDAY NIGHT: Partly cloudy. Lows 52-59. Wind E under 10 MPH.

TUESDAY: Partly cloudy. Highs 68-75, coolest coast. Wind E up to 10 MPH.

DAYS 6-10 (JUNE 17-21)

High pressure remains centered to the north and northeast of the region with an easterly to southeasterly air flow modifying temperatures while weather remains dry during the middle of next week, then high pressure shifts more to the southeast allowing a little more of a southerly wind, higher humidity, and a slight increase in the risk of a shower as another frontal boundary gets closer later next week.

DAYS 11-15 (JUNE 22-26)

With low confidence leaning toward a little bit more conventional zonal flow and a more summery feel to the pattern, but still with limited shower and thunderstorm chances.

DAYS 1-5 (JUNE 11-15)

Humidity will be up today ahead of a cold front approaching from the west. The combination of these 2 will also produce lots of cloudiness and the risk of showers. While the thunderstorm risk is present, it’s not as prominent as it would be with more of a southwesterly wind and more sunshine to destabilize the atmosphere. Today’s cloud cover and southerly wind will act as limiting factors, and where there is more sun for a time (Cape Cod area) the wind coming over water for a longer time is even more of a limiting factor for storms in that area. This front will be weakening and washing out as it passes through the region, and while the humidity will come down a few notches for Friday, it won’t dry out that much, so with it being warmer with more sunshine it may still feel somewhat humid, until another frontal boundary or trough comes through sometime Friday evening, devoid of shower activity, but introducing cooler and drier air to start the weekend as high pressure builds across eastern Canada. During the weekend and into Monday, low pressure will take shape just south of New England, but will be on the weaker side and should be held at bay by the high to the north, although the circulation between the 2 will create an easterly air flow which is a cooler set-up for this area during the late spring / early summer due to the cool water of the North Atlantic. While I’m expecting mostly dry conditions during this time, there will be varying amounts of cloudiness to deal with.

TODAY: Mostly cloudy. Scattered showers and a slight risk of thunderstorms. Humid. Highs 75-82, cooler South Coast. Wind S-SW 10-20 MPH with higher gusts.

TONIGHT: Variably cloudy. Risk of showers and possibly a thunderstorm. Humid. Lows 63-70. Wind S-SW 10-20 MPH, higher gusts.

FRIDAY: Partly cloudy. Slightly less humid., Highs 77-84. Wind SW-W 5-15 MPH, higher gusts.

FRIDAY: Variably cloudy. Lows 60-67. Wind W 5-15 MPH shifting to N.

SATURDAY: Variably cloudy. Highs 68-75, coolest coast. Wind N 5-15 MPH shifting to NE.

SATURDAY NIGHT: Variably cloudy. Lows 55-62. Wind NE up to 10 MPH.

SUNDAY: Variably cloudy. Highs 66-73, coolest coast. Wind E up to 10 MPH.

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

MONDAY: Mostly cloudy. Risk of a shower South Coast. Highs 66-73, coolest coast. Wind E 5-15 MPH.

DAYS 6-10 (JUNE 16-20)

The pattern in place over the weekend and Monday will continue through the middle of next week. Close call whether or not low pressure can get close enough to produce some rainfall, but even if it does, it would probably be limited as the overall pattern remains dry. A break-down of this set-up allows a more southerly air flow and warmer and more humid conditions later in the period, but with limited shower and thunderstorm chances still.

DAYS 11-15 (JUNE 21-25)

Large scale pattern is expected to feature a ridge in the middle of the US and a weak to moderate northwesterly air flow over the Northeast. This would be a pattern of variable temperatures but no prolonged heat, but would allow for a little more of a summertime feel. Below normal rainfall is expected but 1 or 2 shower/t-storm chances are possible in this pattern from disturbances moving along the flow.

DAYS 1-5 (JUNE 10-14)

We’ll be in boundary-land for several days, and the position of that and the wind direction will have the biggest impact on the weather for the region. Breaks down this way… Today we’ll be in an easterly air flow ahead of a warm front, with some sun then clouds eventually becoming more dominant, then the front passes tonight and the humidity spikes into Thursday, a day that will feature a lot of clouds but a limited shower threat. There is not really enough instability to kick off widespread or very heavy activity, though a downpour cannot be ruled out here and there, mainly later in the day or evening Thursday as a cold front moves into the region. This front will pass through, technically, as it washes out early Friday which will be less humid, but not that much drier. We’ll have to wait for another boundary and a push of cooler/drier air to arrive by early Saturday, but this boundary should be passing by without any shower activity. High pressure from the Great Lakes to eastern Canada should be strong enough to keep that boundary from becoming much of an issue with wet weather this weekend, although we’ll probably have to deal with some cloudiness at times. Expect the weekend to feature a cooling trend, much like last weekend.

TODAY: Partly sunny. Highs 68-73 coast, 74-79 inland. Wind E-SE 5-15 MPH.

TONIGHT: Mostly cloudy. More humid. Lows 58-65. Wind S up to 10 MPH.

THURSDAY: Mostly cloudy. Scattered showers and possible thunderstorms. Humid. Highs 75-82, cooler South Coast. Wind S-SW 10-20 MPH with higher gusts.

THURSDAY NIGHT: Variably cloudy. Risk of showers and possibly a thunderstorm. Humid. Lows 63-70. Wind S-SW 10-20 MPH, higher gusts.

FRIDAY: Partly cloudy. Slightly less humid., Highs 77-84. Wind SW-W 5-15 MPH, higher gusts.

FRIDAY: Variably cloudy. Lows 60-67. Wind W 5-15 MPH shifting to N.

SATURDAY: Variably cloudy. Highs 68-75, coolest coast. Wind N 5-15 MPH shifting to NE.

SATURDAY NIGHT: Variably cloudy. Lows 55-62. Wind NE up to 10 MPH.

SUNDAY: Variably cloudy. Highs 66-73, coolest coast. Wind E up to 10 MPH.

DAYS 6-10 (JUNE 15-19)

Overall pattern features high pressure in eastern Canada and low pressure south of New England. Low pressure may get close enough for more cloudiness and a risk of some wet weather at times through mid period followed by drier weather again. Temperatures near to below normal.

DAYS 11-15 (JUNE 20-24)

Large scale pattern is expected to feature a ridge in the middle of the US and a weak to moderate northwesterly air flow over the Northeast. This would be a pattern of variable temperatures but no prolonged heat, but would allow for a little more of a summertime feel than the days preceding it will have. Below normal rainfall is expected but 1 or 2 shower/t-storm chances are possible in this pattern from disturbances moving along the flow.

DAYS 1-5 (JUNE 9-13)

Easily my worst forecast for a day in advance in quite some time. The first push of warming at the surface and aloft produced far more cloudiness than I anticipated just 24 hours prior, so we get a cloudy start to the day today and even some patches of rain across southern NH and northeastern MA to go along with it. If I was going to miss that badly it could have at least turned out to be a more significant rainfall to help out with our abnormally dry conditions, but that’s not the case. So today will feature less sun than I had previously advertised here as we get a warm front starting to approach the region and a northwesterly air flow aloft pushing moisture down across the region. This is not an atypical late spring / early summer set-up here, but I didn’t anticipate it being this pronounced. Other than the showers that are around to start the day, I don’t expect much more in the way of precipitation until Wednesday night when we have gotten into the warm and more humid air and then a cold front will approach from the west, continuing that chance of shower and possible thunderstorm activity Thursday. This front will clear the region Friday with a push of slightly drier air into the region, although it will be the warmest of the next 4 days. Things change on Saturday when high pressure builds in eastern Canada and we turn cooler again, probably with some cloudiness but dry weather.

TODAY: Mostly cloudy. Showers possible through mid morning southern NH and eastern MA. Highs 73-80. Wind NW 5-15 MPH becoming variable.

TONIGHT: Mostly cloudy. Lows 55-62. Wind variable up to 10 MPH becoming E.

WEDNESDAY: Partly sunny. Highs 67-74 coast, 75-82. Wind E-SE 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Risk of showers. More humid. Lows 58-65. Wind S up to 10 MPH.

THURSDAY: Variably cloudy. Scattered showers and possible thunderstorms. Humid. Highs 77-84, cooler South Coast. Wind S-SW 10-20 MPH with higher gusts.

THURSDAY NIGHT: Variably cloudy. Risk of showers and possibly a thunderstorm. Humid. Lows 63-70. Wind S-SW 10-20 MPH, higher gusts.

FRIDAY: Partly cloudy. Slightly less humid., Highs 77-84. Wind SW-W 5-15 MPH, higher gusts.

FRIDAY: Variably cloudy. Lows 60-67. Wind W 5-15 MPH shifting to N.

SATURDAY: Variably cloudy. Highs 68-75, coolest coast. Wind N 5-15 MPH shifting to E.

DAYS 6-10 (JUNE 14-18)

Overall pattern features high pressure in eastern Canada and low pressure south of New England. High pressure should be strong enough for dry weather to start, then low pressure may be close enough for more cloudiness and occasional showers middle of the period before drier weather returns later in the period. Even with a potential period of unsettled weather in here it does not look like our region will receive very much in the way of beneficial rain.

DAYS 11-15 (JUNE 19-23)

Large scale pattern is expected to feature a ridge in the middle of the US and a weak to moderate northwesterly air flow over the Northeast. This would be a pattern of variable temperatures but no prolonged heat, but would allow for a little more of a summertime feel than the days preceding it will have. Below normal rainfall is expected but 1 or 2 shower/t-storm chances are possible in this pattern from disturbances moving along the flow.
