DAYS 1-5 (JULY 28 – AUGUST 1)<\/p>\n\n\n\n
A relatively minor hot spell goes on today into Saturday before a big change. Portions of the region saw showers and thunderstorms late Thursday, some of the storms producing damaging wind gusts and torrential rainfall, along with some instances of frequent lightning, while other areas were less impacted. This was expected. Today, while we keep the heat, we get a little reduction in humidity for much of the region as a down-sloping wind from the west drives the dew point down for a while. The exception will be the South Coast where the muggy air will be stubborn. This higher humidity then makes its way northward again tonight into Saturday, and as it does so, a few showers and thunderstorms can form in response to the increased dew points, especially later Saturday morning with a little help from the sun’s heating. But not far behind this is a cold front which will charge across the region, pulled by low pressure passing to our north. This front can and likely will trigger a round or two of showers and thunderstorms, with again some severe weather potential. It’s once again important to note that when meteorologists talk about severe weather potential, it’s important to focus on the word “potential” and its definition, and also keep in mind that severe weather is often localized, sometimes hyper-localized, and that the majority of the region will not see events with the storms that qualify as “severe”. Nevertheless many areas can see a gusty shower including torrential downpours, and some can see more powerful thunderstorms at some point Saturday afternoon, maybe lingering into early evening toward the South Coast, as the cold front pushes through. Behind this front comes a shot of Canadian air with cooler temperatures and significantly lower dew points – lowest we’ve seen in quite a while, to close out the month of July on Sunday and Monday. I’d like to forecast unlimited sun for Sunday and Monday, but I cannot. The reason is we’ll have a weak cyclonic flow with a hint of an upper trough over the region, which can allow for some diurnal cloud development each day. Pop-up isolated showers are even possible on Sunday, favoring northern MA and southern NH, but I wouldn’t cancel any plans over this slight chance. Tuesday’s weather looks fair and seasonably warm as high pressure builds over the region.<\/p>\n\n\n\n
TODAY: Mostly sunny. Highs 88-95, hottest interior valleys, except cooler portions of South Coast. Dew point lowering through the 60s except staying in upper 60s to lower 70s. South Coast. Wind W 5-15 MPH in the morning, diminishing slightly in the afternoon when some local coastal sea breezes are possible.<\/p>\n\n\n\n
TONIGHT: Partly cloudy. Lows 70-77. Dew point 65+. Wind SW up to 10 MPH.<\/p>\n\n\n\n
SATURDAY: Variably cloudy. Scattered showers\/thunderstorms. Highs 85-92, cooler South Coast. Dew point 65+. Wind SW 5-15 MPH shifting to NW by late.<\/p>\n\n\n\n
SATURDAY NIGHT: Clearing. Lows 58-65. Dew point falling to 50s. Wind NW 5-15 MPH.<\/p>\n\n\n\n
SUNDAY: Sunny to partly cloudy. An isolated shower is possible mainly north of I-90. Highs 76-83. Dew point below 60. Wind NW 5-15 MPH.<\/p>\n\n\n\n
SUNDAY NIGHT: Mostly clear. Lows 55-62. Dew point lower 50s. Wind NW under 10 MPH.<\/p>\n\n\n\n
MONDAY: Mostly sunny. Highs 78-85. Dew point below 60. Wind N up to 10 MPH with light coastal sea breezes.<\/p>\n\n\n\n
MONDAY NIGHT: Partly cloudy early, then mostly clear. Lows 55-62. Dew point below 55. Wind variable under 10 MPH.<\/p>\n\n\n\n
TUESDAY: Sunny. Highs 76-83. Dew point below 60. Wind variable up to 10 MPH.<\/p>\n\n\n\n
DAYS 6-10 (AUGUST 2-6)<\/p>\n\n\n\n
Upper level pattern will feature generally weak zonal (west to east) flow with a weak trough in place, axis mostly to our east. Surface high pressure sits over the region to start the period then shifts to the east allowing humidity to build back in by August 3, then a low pressure area and frontal system from the west brings a shower\/thunderstorm opportunity about August 4 followed by the next shot of drier air from Canada for August 5-6.<\/p>\n\n\n\n
DAYS 11-15 (AUGUST 7-11)<\/p>\n\n\n\n
The upper level generally zonal flow pattern continues, but with a trough a little further west, putting us back into a more humid pattern with a couple more shower \/ t-storm opportunities. No sustained major heat.<\/p>\n","protected":false},"excerpt":{"rendered":"
