Monday Forecast

7:14AM

DAYS 1-5 (SEPTEMBER 30-OCTOBER 4)
This final day of September, much like a good portion of the month, will be another fair weather day under high pressure. However, as we enter October, we’re going to change things up a bit over the first several days, with a warm front crossing the region Tuesday, bringing a spike of warm and somewhat more humid air into the area, followed by a cold front which will turn Wednesday into an “upside down” temperature day along with a rain shower threat. This front will introduce significantly cooler air, the coolest of the young autumn season so far, and a wave of low pressure moving along it as it slows down just south of here will bring a period of chilly rain later Thursday to early Friday, before it starts to dry out later Friday.

DAYS 11-15 (OCTOBER 10-14)
Overall pattern much the same, drier than average, up and down temperatures.

Sunday Forecast

8:21AM

DAYS 1-5 (SEPTEMBER 29-OCTOBER 3)
No changes again. Quick summary. Two nice day to end September, a quick shot of summer-like warmth to start October followed by a fairly strong but slow moving cold front which brings unsettled weather in during Wednesday and again later Thursday as a wave of low pressure moves along it, and after a warm start Wednesday things go the other way, turning much cooler by Thursday.
Forecast details…
TODAY: Mostly sunny. Highs 68-75. Wind NE 5-15 MPH.
TONIGHT: Mostly clear. Lows 48-55. Wind E under 10 MPH.
MONDAY: Mostly sunny. Highs 70-77. Wind SE 5-15 MPH.

THURSDAY: Variably cloudy. Chance of rain late-day or night. Highs 58-65. Wind NE to E 5-15 MPH.

DAYS 6-10 (OCTOBER 4-8)
A low pressure wave departing the region October 4 will bring wet weather to start then a drying trend. High pressure in eastern Canada will bring fair and cool weather for the October 5-6 weekend followed by a moderating trend as the high center slides to the southeast early next week with continued mainly dry weather.

DAYS 11-15 (OCTOBER 9-13)
Mainly fair, milder start to this period then unsettled weather returns with a cool-down later as the same general pattern continues, but with slower transitions.

Saturday Forecast

8:23AM

DAYS 1-5 (SEPTEMBER 28-OCTOBER 2)
Again the ride is relatively easy, from a forecasting standpoint, with only one rain threat this weekend, from a cold front which will produce some showers tonight. Otherwise, it’s dry, with temperatures starting with a bit of summer feel today, then a more seasonably cool couple days to end September early in the week, and a quick reminder that summer left us not too long ago as we start October with another quick warm shot of air. How long that lasts into the second day of the month will depend on the timing of a cold front dropping southward out of Canada. Right now at several days out I am seeing signs of an “upside down” day, one that starts warm, and ends much cooler. This may need to be tweaked, of course, based on the timing of the front. The other wild card for day 5 is how much rain occurs. Also will need to fine-tune that the next few days.
Forecast details…
TODAY: Mostly sunny. Highs 75-82. Wind SW 5-15 MPH.
TONIGHT: Variably cloudy. A few rain showers possible, any may be briefly heavy. Lows 58-65. Wind W 5-15 MPH, shifting to N overnight.
SUNDAY: Mostly sunny. Highs 68-75. Wind NE 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Lows 48-55. Wind E under 10 MPH.
MONDAY: Mostly sunny. Highs 70-77. Wind SE 5-15 MPH.
MONDAY NIGHT: Mostly clear. Lows 50-57. Wind S up to 10 MPH.
TUESDAY: Mostly sunny. Highs 73-80. Wind SW 10-20 MPH.
TUESDAY NIGHT: Partly cloudy. Lows 55-62. Wind SW 5-15 MPH.
WEDNESDAY: Early sun, then lots of clouds with rain showers arriving. Highs 70-77 early, turning cooler later. Wind W 10-20 MPH shifting to N.

DAYS 6-10 (OCTOBER 3-7)
High pressure in eastern Canada will provide cooler air for this 5-day period, but may be far enough north to allow an area of low pressure to bring a period of rain about October 4. We’ll have to watch for an upper level low to produce a few showers October 5 but otherwise the October 5-6 weekend looks mainly dry, just cool.

DAYS 11-15 (OCTOBER 8-12)
Slower transitions means we come out of the cool spell into a more gradual moderation that lasts much of this period. Also expecting dry weather to be dominant with no strong sign of a turn to a wetter pattern at this point.

Friday Forecast

7:19AM

DAYS 1-5 (SEPTEMBER 27-OCTOBER 1)
No changes to the forecast. Up and down on the temps, mainly dry with the weather. Only rain threat for this 5-day period is passing showers Saturday night with a cold front crossing the region.
Forecast details…
TODAY: Mostly sunny. Highs 68-75. Wind NW 5-15 MPH.
TONIGHT: Mostly clear. Lows 48-55. Wind W up to 10 MPH.
SATURDAY: Mostly sunny. Highs 75-82. Wind SW 5-15 MPH.
SATURDAY NIGHT: Variably cloudy. A few rain showers possible. Lows 58-65. Wind W 5-15 MPH, shifting to N overnight.

MONDAY NIGHT: Mostly clear. Lows 50-57. Wind S up to 10 MPH.
TUESDAY: Mostly sunny. Highs 73-80. Wind SW 10-20 MPH.

DAYS 6-10 (OCTOBER 2-6)
Transition day October 2 which starts warm, may get wet for a while, and ends cooler as a cold front drops southward out of Canada. High pressure to the north of the region finally settles over the region later in the period, the balance of which will be dry with near to below normal temperatures.

DAYS 11-15 (OCTOBER 7-11)
The overall pattern will not have changed too much, but may be “slower”, in that it takes this 5 day period for one warm-up, brief shower threat, cool-down cycle.

Thursday Forecast

7:19AM

DAYS 1-5 (SEPTEMBER 26-30)
The final 5 days of September will continue the up and down temperature but mainly dry weather pattern as the only disturbances come in the form of weak fronts passing by this evening and Saturday night, with high pressure in control otherwise.
Forecast details…
TODAY: Sunshine this morning. Clouding up this afternoon with showers arriving west to east late-day. Highs 75-82. Wind SW 5-15 MPH.
TONIGHT: Mostly cloudy evening with showers departing west to east early. Clearing thereafter. Lows 56-63. Wind SW 5-15 MPH shifting to NW.
FRIDAY: Mostly sunny. Highs 68-75. Wind NW 5-15 MPH.
FRIDAY NIGHT: Mostly clear. Lows 48-55. Wind W up to 10 MPH.

SUNDAY: Mostly sunny. Highs 68-75. Wind NE 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Lows 48-55. Wind E under 10 MPH.
MONDAY: Mostly sunny. Highs 70-77. Wind SE 5-15 MPH.

DAYS 6-10 (OCTOBER 1-5)
Upper high pressure surges into the Northeast again briefly to start October with more above normal temperatures and mainly dry weather, but a round of showers/thunderstorms later October 2 may be followed by a push of much cooler air around October 3-4 then moderation again by the end of the period as the overall pattern still has not changed much.

DAYS 11-15 (OCTOBER 6-10)
Still somewhat of an up and down temperature pattern and only brief shower threats expected. Canada will be trending colder, not only as it is seasonally what happens but the pattern will support colder air there. This will be watched but so far not seeing solid signs of big pattern changes.

Wednesday Forecast

6:59AM

DAYS 1-5 (SEPTEMBER 25-29)
A temperature kiddie coaster will continue with a mainly dry weather pattern, with just weak cold fronts passing by Thursday evening and Saturday night providing the only rain shower threats of the next 5 days. Otherwise, high pressure will retain its overall dominance.
Forecast details…
TODAY: Mostly sunny. Highs 70-77. Wind N 5-15 MPH.
TONIGHT: Mostly clear. Lows 50-57. Wind W up to 10 MPH.
THURSDAY: Partly sunny. Risk of a late-day rain shower mainly north and west of Boston. Highs 75-82. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 48-55. Wind W up to 10 MPH.
SATURDAY: Mostly sunny. Highs 75-82. Wind SW 5-15 MPH.
SATURDAY NIGHT: Variably cloudy. A few rain showers possible. Lows 58-65. Wind W 5-15 MPH, shifting to N overnight.
SUNDAY: Mostly sunny. Highs 68-75. Wind NE 5-15 MPH.

DAYS 6-10 (SEPTEMBER 30-OCTOBER 4)
Upper high pressure surges into the Northeast again briefly to end September and start October with more above normal temperatures and mainly dry weather, but a round of showers/thunderstorms around October 2 may be followed by a push of much cooler air around October 3-4.

DAYS 11-15 (OCTOBER 5-9)
While a whole sale pattern change will eventually take place it will probably evolve over time and not really be here at this point, so we should warm back up somewhat at least a few of the days of this period with another cool push possible to end it. Still the overall pattern is expected to be drier than average.

Tuesday Forecast

7:18AM

DAYS 1-5 (SEPTEMBER 24-28)
Upper level low pressure will cross the region today, and while we won’t feel the summerlike heat of yesterday, it will still be warm at the surface, contrasted with colder air aloft, and that will make it unstable, so clouds will pop up and a few showers/thunderstorms likely result. Not everybody gets them, but brief heavy downpours may occur sometime this afternoon to very early evening. High pressure builds in tonight and Wednesday with tranquil weather, then the high slides offshore and a quick warm-up occurs Thursday, with another cold front possibly bringing a brief shower at night before another high pressure area builds in with slightly cooler weather for Friday. This high, like its predecessor, will move offshore and allow another warm-up for Saturday.
Forecast details…
TODAY: Clouds depart Cape Cod early. Sunshine elsewhere into mid morning then a sun/cloud mix late morning on. Isolated to scattered showers and a slight chance of thunderstorms this afternoon. Highs 73-80. Wind NW 5-15 MPH, higher gusts.
TONIGHT: Clearing. Lows 46-53. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 70-77. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. Lows 50-57. Wind W up to 10 MPH.
THURSDAY: Mostly sunny. Highs 75-82. Wind SW 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. Risk of a passing shower. Lows 56-63. Wind SW 5-15 MPH shifting to NW.
FRIDAY: Mostly sunny. Highs 68-75. Wind NW 5-15 MPH.
FRIDAY NIGHT: Mostly clear. Lows 48-55. Wind W up to 10 MPH.
SATURDAY: Mostly sunny. Highs 75-82. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 29-OCTOBER 3)
The upper pattern will see the high pressure ridge, still centered in the Midwest, try to bubble east again, which keeps the overall pattern dry, but again we’ll see some temperature ups and downs, though the tendency for this 5-day period will likely be the warmer side of normal. Some details remain uncertain in terms of wind direction and specific temperatures, which will be fine-tuned.

DAYS 11-15 (OCTOBER 4-8)
The upper ridge is expected to back-up more toward the Plains leaving the Northeast in a more west to east upper level low, but one or two intrusions of much cooler air from Canada are going to be more possible, the timing of which is uncertain at this time. It may become a little more unsettled near the boundary of this chilly air to the north and warmer air still to the south, but it does not look like we’ll be diving into a wet pattern either.

Monday Forecast

7:01AM

DAYS 1-5 (SEPTEMBER 23-27)
Autumn has arrived, but it will still feel like summer today with a warm, more humid southwesterly air flow ahead of a cold front. This front will cross the region tonight, producing showers and possibly a thunderstorm, then be offshore by dawn Tuesday, a day which will be cooler and drier, but with some passing cloudiness due to a pocket of colder air aloft. These clouds may release a few sprinkles or light showers but these will be the exception and far from the rule. High pressure pushes in with fair and seasonably mild weather Wednesday, then drifts off to the east with a quick warm-up for Thursday, before a weak cold front comes through with hardly any clouds and no rain threat Thursday night, knocking the temperature back to seasonable levels for Friday with more dry weather.
Forecast details…
TODAY: Mostly sunny through mid afternoon. Partly sunny late afternoon. More humid. Highs 75-82 South Coast, 82-89 elsewhere. Wind SW 10-20 MPH.
TONIGHT: Partly to mostly cloudy. Scattered to numerous showers and a slight chance of a thunderstorm west to east mid evening to overnight. Patchy fog. Humid. Lows 60-67. Wind SW 5-15 MPH shifting to NW toward dawn.
TUESDAY: Partly sunny. Slight risk of isolated showers. Highs 68-75. Wind NW 10-20 MPH.
TUESDAY NIGHT: Clearing. Lows 45-52. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 70-77. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. Lows 50-57. Wind W up to 10 MPH.
THURSDAY: Mostly sunny. Highs 73-80. Wind SW 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Lows 50-57. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 68-75. Wind NW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 28-OCTOBER 2)
A little flatter flow allows a quick warm-up September 28, a front to pass through late-day or night with maybe a shower, then a slight cool down for September 29. The cycle repeats September 30 with a warm-up then a slight cool-down to begin October as high pressure builds over eastern Canada.

DAYS 11-15 (OCTOBER 3-7)
A quick return to ridging then a flatter flow follows with a strong west to east jet stream keeping systems weak and weather mainly dry. Warmest weather relative to normal will likely be early in the period then more seasonable air follows.

Sunday Forecast

7:24AM

DAYS 1-5 (SEPTEMBER 22-26)
The autumnal equinox, the start of fall, is 4:50AM Monday. This final day of summer and first day of fall will both feel like summer, with a warm southwesterly air flow in place, but stronger Monday, ahead of an approaching cold front. That front may produce a passing shower sometime in the dark hours of Monday night / Tuesday morning, and will replace the summery air with a more seasonably cool batch of air Tuesday-Wednesday before it warms a bit more by Thursday. Upper level low pressure crossing the region Tuesday probably means we’ll see more clouds in the sky than we’ve seen recently, but high pressure should reassert enough control for lots of sunshine by midweek.
Forecast details…
TODAY: Mostly sunny. Highs 79-86. Wind SW 5-15 MPH.
TONIGHT: Mostly clear. Lows 58-65. Wind SW 5-15 MPH.
MONDAY: Mostly sunny. Highs 78-85. Wind SW 10-20 MPH.
MONDAY NIGHT: Variably cloudy. Chance of a passing shower. Lows 60-67. Wind SW 5-15 MPH shifting to NW.
TUESDAY: Partly sunny. Highs 68-75. Wind NW 10-20 MPH.
TUESDAY NIGHT: Clearing. Lows 45-52. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 70-77. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. Lows 50-57. Wind W up to 10 MPH.
THURSDAY: Mostly sunny. Highs 73-80. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 27-OCTOBER 1)
Mainly dry, high pressure ridge centered southwest of New England with west to northwest air flow at upper levels and only a couple minor disturbances passing by with minimal shower threats. Temperatures near to above normal, a little variable from today to day depending on where surface high pressure is centered and resultant wind direction.

DAYS 11-15 (OCTOBER 2-6)
No significant change expected, overall dry, variable temperatures but averaging slightly above normal overall.

Saturday Forecast

7:30AM

DAYS 1-5 (SEPTEMBER 21-25)
Same story, high pressure in control, and our warm-up will really be felt this weekend and Monday. Humidity will be low this weekend but will come up somewhat Monday as a stronger southwesterly air flow arrives. High pressure gives way to a cold front that crosses the region in the early hours of Tuesday followed by a small upper level low Tuesday, which will bring cooler air from Canada. High pressure moves back into control by Wednesday but with its center northwest of New England we’ll still be in a cooler northerly air flow.
Forecast details…
TODAY: Mostly sunny. Highs 76-83. Wind SW 5-15 MPH.
TONIGHT: Mostly clear. Lows 56-63. Wind SW up to 10 MPH.
SUNDAY: Mostly sunny. Highs 79-86. Wind SW 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Lows 58-65. Wind SW 5-15 MPH.
MONDAY: Mostly sunny. Highs 78-85. Wind SW 10-20 MPH.
MONDAY NIGHT: Variably cloudy. Chance of a passing shower. Lows 60-67. Wind SW 5-15 MPH shifting to NW.
TUESDAY: Partly sunny. Highs 68-75. Wind NW 10-20 MPH.
TUESDAY NIGHT: Clearing. Lows 45-52. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 70-77. Wind N 5-15 MPH.

DAYS 6-10 (SEPTEMBER 26-30)
A very similar pattern to days 1-5, warming up early in the period, a cold front sliding through with maybe a shower sometime later September 27 or early September 28, then slightly cooler.

DAYS 11-15 (OCTOBER 1-5)
October picks up where September leaves off with an up and down temperature but dry weather pattern as large scale high pressure ridging is dominant, the center of which will probably remain in the east central US with some oscillation, which will eventually help determine daily temperatures and the allowance of any fronts to pass through.
