DAYS 1-5 ( JULY 21-25)

High pressure builds from the Great Lakes to just south of New England through tonight, and while today will still be very warm to hot, it will be less humid and more comfortable. Cloudiness will make a come-back on Wednesday ahead of a warm front which will also bring a risk of showers, a slight risk of thunderstorms, and a return to higher humidity, which lasts through Thursday until a cold front passes by at night. It’s difficult to say where the warm front will be at any given time, but from later Wednesday through Wednesday night, we run the risk of an isolated severe storm or two near it and should keep a close eye out for this. Ahead of the cold front, expect a continued shower/thunderstorm risk during Thursday. Somewhat cooler and significantly drier air arrives behind that cold front for Friday. High pressure builds in with continued fair and pleasant mid summer weather for Saturday.

TODAY: Mostly sunny. Less humid. Highs 85-92 except cooler Cape Cod. Wind W 5-15 MPH.

TONIGHT: Mostly clear evening. Increasing clouds overnight. Lows 60-67. Wind variable under 10 MPH.

WEDNESDAY: Mostly cloudy. Risk of showers. Highs 77-84, coolest coast. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Risk of a few showers and thunderstorms. Humid. Lows 65-72. Wind SW up to 10 MPH.

THURSDAY: Variably cloudy. Chance of showers and thunderstorms. Humid. Highs 80-87. Wind SW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Variably cloudy with a chance of showers and thunderstorms evening. Clearing overnight. Patchy fog lower elevations. Less humid. Lows 58-65. Wind NW 5-15 MPH.

FRIDAY: Mostly sunny. Highs 77-84. Wind NW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 58-65. Wind N up to 10 MPH.

SATURDAY: Mostly sunny. Highs 80-87, cooler in some coastal areas. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JULY 26-30)

A trough of low pressure may bring a passing shower or thunderstorm July 26. Fair July 27. Another disturbance brings a shower / thunderstorm threat July 28 before drier weather arrives again at the end of the period. Temperatures near to slightly above normal overall.

DAYS 11-15 (JULY 31 – AUGUST 4)

West to northwest flow aloft, a seasonably warm to occasionally hot mid summer pattern but no lasting or extreme heat expected. Occasional opportunities for showers and thunderstorms but drier than average overall for most of the region.

DAYS 1-5 ( JULY 20-24)

A weak cold front will cross southeastern New England today and this evening, slicing into the hot & humid air we have in place. This will trigger some shower and thunderstorm activity, and timing suggests that maximum heating will result in the greatest chance of heavier showers and storms will occur from the I-95 belt southeastward during the afternoon. Drying takes place tonight, and Tuesday will be very warm and moderately humid, but noticeably more comfortable than today will be. Both tonight and Tuesday night should afford better opportunities to view Comet NEOWISE which appears in the northwesterly sky below the Big Dipper, visible to the naked eye if you have a fairly unobstructed view after 9:35 into the early morning hours. Cloudiness will make a come-back on Wednesday ahead of a warm front which will also bring a risk of showers and a return to higher humidity, which lasts through Thursday until a cold front passes by at night. Ahead of that front, expect a shower/thunderstorm risk. Somewhat cooler and significantly drier air will arrive beyond that cold front on Friday.

TODAY: Mostly cloudy morning with isolated showers. Partly sunny afternoon with isolated to scattered showers and possible thunderstorms, favoring the I-95 corridor southeastward. Very humid. Highs 87-94 except cooler South Coast. Wind SW 5-15 MPH.

TONIGHT: Clearing. Less humid. Lows 65-72. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Moderately humid. Highs 85-92 except cooler Cape Cod. Wind W up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 60-67. Wind variable under 10 MPH.

WEDNESDAY: Variably cloudy. Risk of showers. Highs 78-85, coolest coast. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Humid. Lows 65-72. Wind SW up to 10 MPH.

THURSDAY: Variably cloudy. Chance of showers and thunderstorms. Humid. Highs 80-87. Wind SW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Variably cloudy with a chance of showers evening. Clearing overnight. Patchy fog lower elevations. Less humid. Lows 58-65. Wind NW 5-15 MPH.

FRIDAY: Mostly sunny. Highs 77-84. Wind NW 5-15 MPH.

DAYS 6-10 (JULY 25-29)

A warm front brings increasing clouds July 25 with a risk of a shower at night. A cold front follows for July 26 with higher humidity and a risk for showers and thunderstorms. A west northwest flow means quick-moving summertime weather systems heading toward the end of the month so timing is suspect but expecting dry weather and low humidity for July 27, a quick return to humidity with a shower and thunderstorm risk July 28, then drier again at the end of the period.

DAYS 11-15 (JULY 30 – AUGUST 3)

West to northwest flow aloft, a seasonably warm to occasionally hot mid summer pattern but no lasting or extreme heat expected. Occasional opportunities for showers and thunderstorms but drier than average overall for most of the region.

DAYS 1-5 ( JULY 19-23)

You won’t find any changes to the forecast posted yesterday, so here’s a quick summary. Yesterday was the first hotter day of the stretch we’re in now, although the dew points did drop off during the day in many areas, keeping it more comfortable than it will turn out during the next 2 days. Heat/humidity increases today and the combination of both peaks Monday, which will also be a day that carries a shower and thunderstorm risk as a weak cold front approaches. This front will take the edge off the heat and drop the humidity back somewhat by Tuesday. A warm front approach Wednesday with more cloudiness and a shower risk, along with increasing humidity, which hangs around through Thursday as a cold front approaches, along with another risk of showers and thunderstorms.

TODAY: Mostly sunny. More humid. Highs 90-97 except cooler Cape Cod / South Coast. Wind WSW 5-15 MPH.

TONIGHT: Partly cloudy. Humid. Lows 73-80. Wind SW up to 10 MPH.

DAYS 1-5 ( JULY 18-22)

3 days of summer heat (will be an official heatwave for any areas that reach or exceed 90 all 3 days). High pressure brings plenty of sun both today and Sunday and the air coming from the southwest will carry increasing humidity by Sunday. Today, we’ll actually see the dew point drop off a little bit as a batch of drier air arrives despite the increasing heat. The most uncomfortable of the 3 days will be Monday when that will be the maximum combination of heat and humidity, dew points closer to or just over 70, and we will also have to add in the risk of afternoon showers and thunderstorms with an approaching trough of low pressure. This will push through Monday night and break the heat and humidity to some degree (no pun intended) Tuesday. A warm front approaches Wednesday with more cloudiness and a limited risk of showers.

TODAY: Any fog dissipates by 9AM, otherwise sunny. Moderately humid then drying slightly. Highs 86-93, but turning cooler in many coastal areas this afternoon. Wind SW up to 10 MPH with coastal sea breezes developing.

MONDAY: Partly sunny. Chance of showers and thunderstorms in the afternoon. Very humid. Highs 87-94. Wind SW 5-15 MPH.

MONDAY NIGHT: Party cloudy. Chance of a shower or thunderstorm early. Patchy fog. Humid. Lows 65-72. Wind W under 10 MPH.

TUESDAY: Partly cloudy. Less humid. Highs 85-92, except cooler some coastal areas especially Cape Cod. Wind W up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 60-67. Wind variable under 10 MPH.

WEDNESDAY: Variably cloudy. Risk of showers. Highs 78-85, coolest coast. Wind SE 5-15 MPH.

DAYS 6-10 (JULY 23-27)

A cold front approaches and passes through the region July 23 with higher humidity and a risk of showers and thunderstorms. High pressure brings drier air and fair weather July 24. Warm front / cold front combo brings a risk of showers / thunderstorms and higher humidity for the July 25-26 weekend. High pressure brings drier air and fair weather back by July 27.

DAYS 11-15 (JULY 28 – AUGUST 1)

West to northwest flow aloft, a seasonably warm to occasionally hot pattern but no lasting or extreme heat expected. Occasional opportunities for showers and thunderstorms but drier than average overall for most of the region.

DAYS 1-5 ( JULY 15-19)

High pressure centered over eastern Canada will drift slowly southward bringing drier air in for today (which starts on the cloudy and still somewhat humid side) and Thursday. A warm front approaching and moving through the region Friday brings cloudiness, higher humidity, and a risk of showers, then opens the door to some summer heat for the weekend.

TODAY: Clouds break for sun. Drying out. Highs 69-74 coast, 75-80 inland. Wind NE 5-15 MPH.

TONIGHT: Partly cloudy. Patchy fog lower elevations overnight. Lows 55-62. Wind E under 10 MPH.

DAYS 1-5 ( JULY 14-18)

An upper level low pressure area and pool of very cold air aloft will make the atmosphere unstable today with showers and thunderstorms. Initially these storms are limited to parts of southern NH but will develop elsewhere due to the sun’s heating. Some of these storms may produce gusty winds and hail. Activity settles down and departs later tonight, and high pressure centered over eastern Canada, sinking slowly southward, provides fair and comfortable mid July weather Wednesday and Thursday. A warm front approaching and moving through the region Friday brings cloudiness, higher humidity, and a risk of showers, then opens the door to some summer heat by Saturday.

TODAY: Variably cloudy. Isolated thunderstorms in southern NH early to mid morning. Scattered showers and thunderstorms anywhere midday on. Thunderstorms may produce hail, gusty winds, and frequent lightning. Highs 76-83. Wind N-NE 5-15 MPH.

TONIGHT: Mostly cloudy. Scattered showers and thunderstorms diminishing. Patchy fog forming. Lows 56-63 Wind NE up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 72-79, coolest coast. Wind NE 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Patchy fog lower elevations overnight. Lows 55-62. Wind E under 10 MPH.

THURSDAY: Sunny to partly cloudy. Highs 76-83, coolest coast. Wind SE up to 10 MPH.

THURSDAY NIGHT: Increasing clouds. Showers possible overnight. More humid. Lows 60-67. Wind S up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Humid. Lows 65-72. Wind SW up to 10 MPH.

SATURDAY: Mostly sunny. Humid. Highs 85-92. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 19-23)

Very warm to hot, humid, but rain-free weather for July 19. Early next week July 20-21 humidity stays high in a southwesterly flow but approaching and passing cold front brings the risk of showers and thunderstorms. Middle of next week July 22-23 brings fair and somewhat drier weather.

DAYS 11-15 (JULY 24-28)

West to northwest flow aloft heading into late July, a seasonably warm to occasionally hot pattern but no lasting or extreme heat expected. Occasional opportunities for showers and thunderstorms but not a wet pattern overall.
