After an eventful week which included a fairly powerful wind/rain storm, we will see a mix of tranquil and volatile weather this coming week.

OVERVIEW…
The week will open with high pressure sinking to the south and a warm front approaching then passing, with a warming trend into Wednesday, then a cold front cooling things down toward the end of the week. A potent upper level system born of a Pacific tropical cyclone may bring some unsettled weather followed by a cold blast as Halloween leads into November.

DETAILS…
Monday will be a fair but breezy day as low pressure moves through eastern Canada and an extension of high pressure over the US Mid Atlantic moves into the Northeast with a westerly flow between them. Low pressure will then move northeastward through the Great Lakes Tuesday and into eastern Canada Wednesday. Its warm front will pass by early Tuesday introducing warmer air to the region. Its cold front will swing in from the west by Wednesday but will have limited moisture to work with, so it will bring only a risk of passing showers and that day will also be quite mild. Some cooler air will work in during Thursday as weak high pressure follows a secondary front into the region. Meanwhile, the low pressure area that was once a tropical cyclone (Ana) in the Pacific Ocean will enter western Canada then cross the country during the middle of the week. This system has a long history, having been born on October 13 nearly 1000 miles east southeast of the Hawaiian Islands. It made a close pass to the islands but not a direct hit on October 18 and 19 as a hurricane, and since has curved to the north and northeast and lost its tropical characteristics. It is still a pretty potent storm system, however, and in transitioned state will have an impact on the weather here in New England when it finally completes its journey here late Friday into Saturday. As it does so it will be tapping some cold air that has leaked into Canada from Siberia. The result will be clouds moving in during the day Friday, leading to a Halloween Night that may turn wet and eventually white in some areas if the cold air works in quickly enough. This will need to be watched as it does carry potential for putting down some of the first accumulating snow of the season. By Saturday, the small but energetic system will be exiting to the east but will still have enough influence on the weather to bring the threat of rain/snow showers, along with colder air and windy conditions. The expansion of this low as it intensifies to the east up against high pressure trying to build in from the west on Sunday will allow windy and cold weather to continue. Of course, any forecast more than a few days out is going to carry some uncertainty, so please check back for updates on the late week situation.

Short discussion (full one later with The Week Ahead post)…
Today… Upper level low pressure passing north of the region but lobe of energy on the southern side of it comes across as we undergo cold air advection at the surface. This combines for a gusty wind, cooler air, a variably cloudy sky which may become mostly cloudy at times, and a slight risk of passing light rain showers (but no widespread rain).
Tonight… Clouds decrease but wind stays gusty as cool air continues to flow into the region.
Monday… High pressure builds just south of the region while low pressure continues to slowly push away to the north, allowing for plenty of sun but still a gusty breeze.
Monday night / Tuesday… Some cloudiness but but then a fair amount of sun returning during the day Tuesday as warm air moves in first aloft then at the surface as a warm front moves through.
Tuesday night / Wednesday… Additional cloudiness but some sun as well during the day Wednesday, also cannot rule out a band of scattered to widespread showers passing by along a cold front that does not have too much moisture to work with.
Thursday… Weak high pressure but enough to provide fair weather with cooler air.
Friday… Starts nice but clouds advance ahead of a low pressure trough.
Friday night (Halloween) / Saturday (November 1)… Not sure how a trough and low pressure evolve along the East Coast just yet. Going to stay away from major storm development at this point, though there have been several computer model runs that have hinted at it. So this part of the forecast subject to significant change.

SOUTHEASTERN NEW ENGLAND FORECAST…
TODAY: Variably cloudy. Slight chance of passing light rain showers during the afternoon. Highs 53-60. Wind W 10-20 MPH with higher gusts.

SATURDAY: Variably cloudy. Chance of rain and snow showers. Low 35. High 45.

7:34AM

The cut-off low pressure area will finally wander away today and tonight but not after causing one more mainly cloudy and partially damp day today. This will be replaced by a fast-flowing jet stream pattern with changing weather over the next several days. The weekend will feature fair and mild weather Saturday, fair and cool weather Sunday, bisected by a cold front Saturday night with no more than a few showers. A warm front slides into the region Monday with some cloudiness to start, more sun to finish, and the start of a warm-up, which will continue Tuesday and Wednesday before a cold front slides through late Wednesday with some clouds and a shower risk. A small area of high pressure comes along Thursday with fair weather and slightly cooler air, based on current timing.

SOUTHEASTERN NEW ENGLAND FORECAST…

Right off the bat let me state that even though I expected this storm to pack a bit of a punch, it is a more powerful one than I anticipated. Things have come together just so to make low pressure intensify rapidly just southeast of New England, creating strong, gusty northeast winds and bands of heavy rain including lightning and thunder. As of the writing of this blog entry (about midnight Wednesday night) the storm is peaking and will continue to do so into the early morning hours with additional strong wind gusts and bands of heavy rain including the chance of thunderstorms. Some coastal flooding has occurred with a recent high tide and may repeat again with the late morning high tide Thursday, not severe flooding but significant enough in some areas for some disruptions to travel on coastal roads and minor damage to property. Beach erosion will also be an issue. Scattered power outages mainly from downed trees and tree limbs have been occurring and will continue into the morning. Once the afternoon arrives, things will wind down more steadily with rain becoming more scattered and lighter, and wind slackening slowly. It will take well into Friday for the storm to really start to loosen its grip, as Friday will contain lots of clouds and some risk of additional wet weather. Improvement comes over the weekend, though it will still be fairly breezy with briefly milder weather Saturday and a cooler Sunday. The first half of next week looks fair with a warming trend as high pressure builds in then slips off the coast.

SOUTHEASTERN NEW ENGLAND FORECAST…
OVERNIGHT: Overcast. Bands of rain, some heavy to very heavy, including lightning and thunder. Other times just drizzle. Temperatures steady upper 40s to lower 50s. Wind NE 15-35 MPH with gusts 40-60 MPH, strongest along the coast.
THURSDAY: Overcast. Bands of moderate to heavy rain including a chance of thunderstorms with drizzle at other times in the morning, tapering to more scattered areas of light to moderate rain with drizzle as well in the afternoon. Temperatures steady upper 40s to lower 50s. Wind NE to N 15-30 MPH with higher gusts, diminishing slightly later in the day.
THURSDAY NIGHT: Cloudy with periods of rain. Lows around 50. Wind N 15-35 MPH.
FRIDAY: Mostly cloudy with scattered rain showers. Highs 55-60. Wind N 15-25 MPH and gusty.
SATURDAY: Partly cloudy. Passing rain shower late. Low 45. High 65.
SUNDAY: Partly sunny. Low 45. High 60.
MONDAY: Partly cloudy. Low 35. High 55.
TUESDAY: Mostly sunny. Low 45. High 65.
WEDNESDAY: Partly cloudy. Low 48. High 70.

11:26PM

No big changes for this update. The evolution of low pressure is going to take place as described in the previous post, resulting in an unsettled to stormy period of weather Tuesday into Friday. The system has quite a bit of energy with it, so one change is to add a risk of thunder with some of the heaviest rain bands. There is still a little uncertainty as to where the heaviest bands will set up, but it appears that the most likely area for heaviest rain will be northern MA northward from the first impulse Tuesday night/Wednesday and anywhere in the region from a second impulse Wednesday night/Thursday. It should all wind down on Friday as low pressure starts to pull away to the east and the wind turns more to the north, pulling drier air in. It still looks like a breezy weekend, coolest on Sunday, but for this update going to ease up on the degree of the chill over what was forecast in the previous blog.

SOUTHEASTERN NEW ENGLAND FORECAST…
OVERNIGHT: Mostly cloudy. Increasing chance of showers. Lows 50-55. Wind light S to SE.
TUESDAY: Mostly cloudy. Periods of showers, locally heavy, with a slight chance of thunderstorms. Highs around 60. Wind SE to E 5-15 mph.
TUESDAY NIGHT: Cloudy. Periods of rain, possibly heavy, especially northern MA and southeastern NH. Chance of thunderstorms. Lows in the 50s. Wind E to NE 10-20 MPH, higher gusts along the coast.
WEDNESDAY: Overcast. Periods of rain, possibly heavy. Chance of thunderstorms. Areas of fog. Temperatures steady in the 50s. Wind NE 10-20 MPH with higher gusts especially along the coast.
WEDNESDAY NIGHT: Overcast. Periods of rain, possibly heavy. Chance of thunderstorms. Areas of fog. Temperatures steady in the 50s. Wind NE 15-25 MPH.
THURSDAY: Overcast. Periods of rain. Areas of fog. Temperatures falling to around 50. Wind NE 15-25 MPH.
FRIDAY: Mostly cloudy. Lingering rain showers. Low 45. High 55.
SATURDAY: Partly sunny and windy. Passing PM shower. Low 45. High 62.
SUNDAY: Partly cloudy and windy. Low 40. High 53.
MONDAY: Mostly sunny. Low 38. High 59.

10:24PM

Cold air arrived on Sunday and the overnight hours will see dissipating clouds and slackening wind, allowing temperatures to drop to near to even below freezing in areas just away from the coast. A freeze warning is up for these locations, with a frost advisory closer to the coast.

A sliver of high pressure will be enough to provide a bright and wonderful Autumn Day to start out the new week Monday, then low pressure moving southeastward from the Great Lakes to just south of New England will sit and spin Tuesday through Thursday before starting to lift slowly away at the end of the week. This will bring 4 days of wet, chilly, breezy weather. Improving weather follows for next weekend but some instability may still cause a few rain showers Saturday and rain/snow showers Sunday as colder air again flows back into the region.

SOUTHEASTERN NEW ENGLAND FORECAST…
OVERNIGHT: Clearing. Lows upper 20s inland valleys, lower to middle 30s elsewhere. Wind light NW.
MONDAY: Sunny. Highs in the 50s. Wind light W.
MONDAY NIGHT: Increasing clouds. Lows upper 30s inland valleys, lower to middle 40s elsewhere. Wind light SW.
TUESDAY: Cloudy. Rain developing. Highs in the 50s. Wind E 5-15 MPH.
WEDNESDAY & THURSDAY: Cloudy with periods of rain/wind. Lows around 45. Highs around 55.
FRIDAY: Mostly cloudy with lingering rain showers. Low 45. High 58.
SATURDAY: Sun/clouds, isolated rain showers. Low 42. High 61.
SUNDAY: Sun/clouds, windy. Isolated rain sprinkle/snow flurry. Low 32. High 47.

9:46AM

First, this weekend. It’s a transition weekend, going from a mild Saturday feeling like September to a chilly Sunday feeling like November. But that’s how we come up with averages, and October is a fickle month often combining warmth of Summer-just-ended with first hints of Winter-to-come. We’ll get that this weekend. A few showers will be around today, especially later afternoon, as a cold front approaches. Ahead of it, a gusty southwest breeze will help maintain the last of the mild air for a while. Once the front goes by tonight, the chilly air will flow in as the wind shifts to northwest. This will continue on Sunday which will be a much cooler day. There may be a few instability showers that pop up on Sunday but it will be a mainly dry day. At night, high pressure moves overhead, the sky clears out, and the temperature drops. Frost may be forming in many areas outside urban centers and away from the immediate shore.

Next week (Monday-Friday): Enjoy a bright and cool October day Monday because that will likely be the only time you see the sun for the remainder of this 5-day period (unless we luck out later Friday). As a small high pressure area delivers the nice weather Monday, low pressure will be dropping through the Great Lakes and heading for the northern Mid Atlantic. It will then evolve into a new storm system trapped under an upper level low pressure area that sits and spins for 4 days, starting Tuesday, bringing unsettled and chilly weather to southeastern New England. It’s hard to say at this point how much rain will fall in total during this period, but there is the potential for some significant amounts, which will be good in that it will continue to alleviate the deficit, but could also lead to some flooding issues should it persist heavily enough. We’ll also have to be on the lookout for coastal flooding due to onshore wind over a prolonged period of time and higher astronomical tides around the New Moon (next Thursday).

Late October: It’s not often I offer any detail beyond my normal 7-day forecasting period, but today a little look into what may transpire as we go through the last weekend and work week of October (Saturday October 25 through Friday October 31). Behind the departing prolonged storm should come a windy and colder weekend. There are hints that it may even be cold enough around October 26 for the first snowflakes to fall in some areas, including the Boston area. Not a snowstorm, but rain and snow showers due to cold air moving in while it is also unstable. Following this, a significant warm-up may take place as we head toward Halloween.

SOUTHEASTERN NEW ENGLAND FORECAST…
TODAY: Partly sunny. Scattered rain showers. Remote risk of thunder. Highs from the middle 60s to lower 70s. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Mostly cloudy with scattered rain showers early then partly cloudy. Lows in the 40s. Wind shifting to NW 10-20 MPH with higher gusts.
SUNDAY: Variably cloudy, clouds most dominant midday, sun increasing later. Isolated rain showers possible mainly inland higher elevations. Highs upper 40s interior hills to 50-55 elsewhere. Wind NW 15-25 MPH.
MONDAY: Sunny. Low 34. High 55.
TUESDAY: Cloudy. Late rain. Low 42. High 52.
WEDNESDAY: Cloudy. Periods of rain. Windy. Low 42. High 49.
THURSDAY: Cloudy. Periods of rain. Windy. Low 43. High 48.
FRIDAY: Cloudy. Lingering rain. Windy. Low 44. High 54.

11:05PM

Trough/front #1 is about to push offshore as of late night Thursday / early morning Friday. With it goes the rain and humidity, but Friday will stay rather mild even as drier air flows into the region on a southwest to west wind around broad low pressure to the north. Trough/front #2 will quietly cross New England Friday night taking temperatures down just a touch for Saturday, with stronger trough/front #3 coming through Saturday night / early Sunday with a few showers, and this one will send temperatures into a tumble, resulting in a much cooler day for Sunday. We then get to enjoy a fair but chilly day Monday, but the pattern will evolve into a chilly and unsettled one for the better part of next week as an upper low drops through the Great Lakes and eastern Ohio Valley by the start of the week then slowly moves over and just south of southern New England by the middle of next week. This will result in an unsettled and chilly episode that may last several days.

11:27PM

Tropical air is on a journey northward into New England and will continue to flood into the region through Thursday on a southerly wind. It will be quite warm on Wednesday even with just partial sunshine, but a cold front moving into the region on Thursday will bring showers, including a band or two of heavier rain and thunderstorms especially in the afternoon and evening. This will likely have some impact on the Patriots/Jets game in Foxboro.

By Friday, the wet weather and high humidity be pushing off to the northeast but around a very broad low pressure area there will still be mild air blowing into the region on a west southwest wind. The trend to cool will be a stair-step downward with 70s Friday, 60s Saturday, and 50s by Sunday as a series of troughs and fronts move through and winds gradually shifting more west to northwest by the end of the weekend when it will feel more like the end of October.

Early next week will be governed by high pressure and fair weather with cool to seasonable air.

SOUTHEASTERN NEW ENGLAND FORECAST…

I hope anybody that had today off was able to enjoy it around southeastern New England, despite the day turning more grey than I had forecast. This post does not carry major changes from the previous one, with still some warmer and more humid air on the way in during the next 2 days, and a front crossing the region Thursday with showers and possible thunderstorms. There remains some uncertainly about the weather late in the week as there are still some significant model differences, but for now still leaning toward a drying/cooling trend Friday through the weekend.

8:48PM

The new week starts for some of you while others will be enjoying an extra weekend day on Monday, Columbus Day, but now I’m confused, not about the setup of the week, but the weather that will occur therein. There is some significant disagreement in guidance in the configuration of the jet stream and the timing of weather systems. If you remember my last post, I had a system coming through on Wednesday with wet weather followed by some clearing, then lots of clouds Thursday and better weather Friday. I now am going to lean toward a timing that’s about 24 hours slower, so that fair weather and a warm-up that commences Monday will continue through Wednesday. The wet weather will then come through sometime Thursday with lots of clouds Friday and then fair weather next weekend. But this is lower than average confidence and it will be important to check for updates.

SOUTHEASTERN NEW ENGLAND FORECAST…
TONIGHT: Mostly clear. Patchy valley fog. Lows from 40 deep valleys to 50 coast/urban areas. Calm wind.
MONDAY – COLUMBUS DAY: Sunny to partly cloudy. Highs in the 60s. Wind S 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Lows in the 50s. Wind S 5-15 MPH.
TUESDAY: Partly to mostly cloudy. Highs in the 70s. Wind S 10-20 MPH.
WEDNESDAY: Partly sunny. Low 55. High 75.
THURSDAY: Showers likely. Low 55. High 65.
FRIDAY: Variably cloudy. Low 48. High 62.
SATURDAY: Partly cloudy. Low 45. High 60.
SUNDAY: Mostly sunny. Low 44. High 64.

5:44PM original post
8:50AM Saturday time edit

The weekend is here! And if you are lucky enough to have a 3-day one for Columbus Day then a good portion of this weekend will feature weather that is likely favorable for your plans. The only interruption is the wet start as a wave of low pressure passes south of the region. The timing still looks similar, mainly a morning-midday event. However, it may take into late afternoon for rain to exit Cape Cod and the Islands, so if you are heading there, more patience is required. But that patience will be rewarded with fabulous weather Sunday and Monday not only there but in all locations as high pressure builds in Sunday then offshore Monday. This will allow for a warm up Monday after a crisp/cool Sunday. Whatever your plans, please have a safe weekend!

Looking ahead a little, the warm up that commences Monday will continue Tuesday, and it may get quite a bit warmer than average, depending on the amount of sunshine we have. For now, the forecast will remain unchanged from the previous post, but in the back of your mind you can make note that it may end up warmer than the 74 that is currently there (75-80 potential if enough sun). Still looking like a trough pushes east and sends a front into the region with a band of rain/thunderstorms sometime Wednesday. I believe it will be progressive enough that we may salvage part of Wednesday with some fair and mild weather. It should then turn cooler but not that chilly for later next week with clouds dominant on Thursday as an upper level trough swings through, and sunshine Friday as high pressure builds in. But again, these days are a ways off and there is plenty of time to work out those details.

SOUTHEASTERN NEW ENGLAND FORECAST…
SATURDAY: Cloudy with rain exiting from west to east late morning through early afternoon, from Boston north and west, lingering into later afternoon southeast of Boston especially Cape Cod and the Islands. Clearing northwest of Boston by day’s end. Highs upper 50s to middle 60s. Wind NE to N 5-15 MPH.
SATURDAY NIGHT: Clear. Lows upper 30s to middle 40s. Wind NW 5-15 MPH.
SUNDAY: Sunny. Highs 55-60. Wind NW 5-15 MPH.
MONDAY – COLUMBUS DAY: Partly cloudy. Low 39. High 66.
TUESDAY: Partly cloudy. Low 50. High 74.
WEDNESDAY: AM rain/thunderstorms, PM sun/clouds. Low 55. High 75.
THURSDAY: Variably cloudy. Low 45. High 65.
FRIDAY: Mostly sunny. Low 43. High 63.

5:55PM

No changes to previous discussion and forecast for this post other than to slow the onset of any precipitation from the low pressure wave passing to the south to overnight Friday night instead of late in the day Friday. Still expect whatever is passing by to be moving very rapidly and on the way out by morning or midday Saturday, again with the greatest chance of any rain occurring in southern MA and RI. Still looking for high pressure to move in Sunday with cool and dry weather, followed by a warm-up early next week. A trough from the west will send a band of rain into the region at some point next week, looking like Wednesday at this point. Timing will be fine tuned as we get closer to this event. Looking like an upper low hanging around Thursday with an unstable and cooler day expected.
