7:15AM

DAYS 1-5 (OCTOBER 2-6)
The only change to the forecast for this update is slowing the timing of the rain down for later Thursday to early Friday, shortening its duration slightly, and making it lighter. There is a saying used by some meteorologists: “All systems fail in a drought.” Well, we may not be in drought quite yet but if such events become habitual then we’ll be there sooner rather than later. The remainder of the forecast remains generally unchanged, from today’s warm start / chilly finish to the weekend that looks really nice but with 2 very chilly mornings and a risk of some areas seeing frost.
Forecast details…
TODAY: Mostly cloudy. Scattered to general rain showers. Humid. Highs 70-77 morning, then falling afternoon. Wind W 10-20 MPH morning, shifting to N from north to south during the morning and early afternoon.
TONIGHT: Partial clearing. Patchy fog. Lows 46-53. Wind NE 5-15 MPH.
THURSDAY: Partial sunshine. Highs 55-62. Wind E 5-15 MPH.
THURSDAY NIGHT: Overcast. Periods of rain. Areas of drizzle and fog. Wind NE 5-15 MPH, higher gusts near the coast.
FRIDAY: Overcast with rain tapering off early morning. Breaking clouds later morning and afternoon. Highs 55-62. Wind N 10-20 MPH.
FRIDAY NIGHT: Clearing. Areas of fog forming. Risk of frost interior lower elevations. Lows 35-40 interior low elevations, 40-45 elsewhere except 45-50 urban centers. Wind N 5-15 MPH.
SATURDAY: Sun and passing clouds. Highs 56-63. Wind N 5-15 MPH.
SATURDAY NIGHT: Clear. Frost likely away from coastal and urban locations. Lows 30-35 interior lower elevations, 35-40 elsewhere except 40-45 urban centers and immediate shore. Wind calm.
SUNDAY: Sun filtered by high clouds. Highs 60-67. Wind SE to S up to 10 MPH.

DAYS 6-10 (OCTOBER 7-11)
October 7 looks breezy and mild with late-day or nighttime rain showers as a cold front moves toward the region. October 8 may start wet then clears out, is breezy but cooler as the front moves offshore and high pressure approaches from the west. High pressure then parks over the region October 9-11 with dry weather, chilly mornings and milder afternoons.

DAYS 11-15 (OCTOBER 12-16)
Wash/rinse/repeat. Early outlook is for a similar set-up, slower-moving, dry weather continuing October 12-13 weekend, a quick warm-up followed by shower threat, then drying with a cool-down by the end of the period.

7:07AM

DAYS 1-5 (OCTOBER 1-5)
October is here, and coincidentally here come some changes in the impact of the weather locally, although the overall large scale pattern isn’t changing too much – just more of a temporary readjustment. What happens is the ridge that has been centered in the east central US bringing persistent warmth to areas south and west of New England and warm spells into New England flattens and moves west a little bit and allows a significantly cooler air mass from Canada to visit New England for a few days, beginning tomorrow. But first, we get back into the warm wedge of air today as a warm front, which brought some early rain showers, passes through. You’ll even notice the humidity bump up during the day today and especially tonight, not to oppressive levels, but to the point you’ll feel the change. But a strong cold front will sink southward across the region Wednesday, which will be warmest early in the day, followed by a cool down. All the while, we’ll be somewhat unsettled, and though clouds break during the day today and we get into some sun, they return tonight and dominate through Wednesday along with the threat of additional rain showers. The front does not get all that far to the south and a wave of low pressure comes along it and provides a good chance of rain Thursday to early Friday. Any rain is welcomed as we have been quite dry overall of late. By Saturday, though, we’ll be under control of high pressure, which looks like a chilly but great early fall day.
Forecast details…
TODAY: Mostly cloudy to partly sunny. Risk of rain showers morning. Highs 72-79. Wind S 5-15 MPH.
TONIGHT: Mostly cloudy. Chance of rain showers. Humid. Lows 60-67. Wind SW 10-20 MPH, higher gusts.
WEDNESDAY: Mostly cloudy. Chance of rain showers. Humid turning to damp. Highs 70-77 morning, then falling afternoon. Wind W 10-20 MPH morning, shifting to N from north to south during the morning and early afternoon.
WEDNESDAY NIGHT: Mostly cloudy. Patchy fog. Lows 46-53. Wind NE 5-15 MPH.
THURSDAY: Cloudy. Rain arriving west to east. Highs 53-60. Wind E 5-15 MPH.
THURSDAY NIGHT: Overcast. Rain likely. Patchy fog. Lows 48-55. Wind NE 5-15 MPH.
FRIDAY: Overcast with rain tapering off morning. Breaking clouds afternoon. Highs 55-62. Wind N 10-20 MPH.
FRIDAY NIGHT: Clearing. Areas of fog forming. Lows 40-47. Wind N 5-15 MPH.
SATURDAY: Sun and passing clouds. Highs 56-63. Wind N 5-15 MPH.

DAYS 6-10 (OCTOBER 6-10)
High pressure moves overhead then offshore October 6, a dry day that starts cold with areas of frost and ends milder. October 7 looks warm but with late-day or nighttime rain showers from a cold front, which moves offshore followed by clearing and cooler weather October 8-9 before it moderates by the end of the period.

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

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.
Forecast details…
TODAY: Mostly sunny. Highs 60-67. Wind variable to E up to 10 MPH.
TONIGHT: Increasing clouds. Lows 50-57. Wind SE up to 10 MPH.
TUESDAY: Mostly cloudy. Risk of brief light rain through midday. More humid. Highs 70-77. Wind S 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Chance of rain showers. Humid. Lows 60-67. Wind SW 10-20 MPH, higher gusts.
WEDNESDAY: Mostly cloudy. Chance of rain showers. Humid turning to damp. Highs 70-77 morning, then falling afternoon. Wind W 10-20 MPH morning, shifting to N from north to south during the morning and early afternoon.
WEDNESDAY NIGHT: Mostly cloudy. Patchy fog. Lows 46-53. Wind NE 5-15 MPH.
THURSDAY: Cloudy. Rain arriving west to east. Highs 53-60. Wind E 5-15 MPH.
THURSDAY NIGHT: Overcast. Rain likely. Patchy fog. Lows 48-55. Wind NE 5-15 MPH.
FRIDAY: Overcast with rain tapering off morning. Breaking clouds afternoon. Highs 55-62. Wind N 10-20 MPH.

DAYS 6-10 (OCTOBER 5-9)
High pressure will dominate with great weather for the October 5-6 weekend, starting very chilly with many areas running risk of frost early October 5, then moderating later in the weekend. Early next week looks warm to start, a cold front passing by with showers, then a cooler shot of air, but timing is uncertain.

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

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.
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.
WEDNESDAY NIGHT: Mostly cloudy. Lows 48-55. Wind N to NE 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.

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.

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.
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.

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.

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.
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.
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.

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.
THURSDAY NIGHT: Variably cloudy. Risk of an evening rain shower mainly Boston southeastward. 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.
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.

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.

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.

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.

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.

7:03AM

DAYS 1-5 (SEPTEMBER 20-24)
High pressure dominates aloft and a surface high will sink south of New England allowing the feel of summer to return for the next 4 days. A weak cold front passing through the region Monday night will provide the only rain threat of the 5-day period in the form of a passing shower for some locations, and Tuesday will be slightly cooler as we get into a northwesterly air flow behind that front, though an upper disturbance may produce more cloudiness than we will see any of the 4 days preceding it.
Forecast details…
TODAY: Sunny. Highs 73-80. Wind S up to 10 MPH.
TONIGHT: Clear. Lows 53-60. Wind SW up to 10 MPH.
SATURDAY: Mostly sunny. Highs 76-83. Wind SW 5-15 MPH.
SATURDAY NIGHT: 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.

DAYS 6-10 (SEPTEMBER 25-29)
High pressure dominates with seasonable temperatures September 25 and 29 and warmer than average temperatures the other 3 days.

DAYS 11-15 (SEPTEMBER 30-OCTOBER 4)
High pressure continues to dominate with some up and down to the temperatures, averaging above normal overall, and mainly dry weather.

7:23AM

DAYS 1-5 (SEPTEMBER 19-23)
The dominance of high pressure will continue through Sunday, with the center of the surface high sinking to the south with time, resulting in a warming trend. This high will also play a role in keeping Hurricane Humberto far out at sea, but will not prevent some large ocean swells and rough surf to impact the coast this weekend, so keep that in mind of beaching or boating for the last weekend of summer. During Monday, a cold front will approach from the west and may have just enough moisture to work with to kick off a few showers, probably late-day or night. That’s the only rain risk in the 5-day period.
Forecast details…
TODAY: Sunny. Highs 66-73. Wind light variable becoming SE under 10 MPH.
TONIGHT: Clear. Patchy fog in low-lying interior locations. Lows 47-54. Wind light variable.
FRIDAY: Sunny. Highs 70-77. Wind S up to 10 MPH.
FRIDAY NIGHT: Clear. Lows 50-57. Wind SW up to 10 MPH.
SATURDAY: Mostly sunny. Highs 73-80. Wind SW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 53-60. Wind SW up to 10 MPH.
SUNDAY: Mostly sunny. Highs 76-83. Wind SW 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Lows 58-65. Wind SW 5-15 MPH.
MONDAY: Partly sunny. Risk of a shower late-day or night. Highs 78-85. Wind SW 10-20 MPH.

DAYS 6-10 (SEPTEMBER 24-28)
High pressure ridge backs off then re-surges, putting us in a similar pattern cycle to days 1-5, largely dry, a bit cooler at first then warming up again.

DAYS 11-15 (SEPTEMBER 29-OCTOBER 3)
And yet again, a very similar pattern cycle continues with largely dry weather, probably a quick cool-down then warming back up.

7:31AM

DAYS 1-5 (SEPTEMBER 18-22)
High pressure will be in control and our weather pattern will be quiet, although the previously mentioned things are still very much valid – the potential patchy frost in normal cold spots Thursday morning, and Humberto passing far offshore by the weekend resulting in larger ocean swells, some rough surf, and increased rip current risk at beaches later this week.
