DAYS 1-5 (JUNE 19-23)<\/p>\n\n\n\n
A few forecast tweaks in this update to an otherwise similar outlook to yesterday’s. We start the day under a blanket of stratus clouds for much of the region which will hold back the temperature rise and take a degree or two off the potential high temps for the day, but we’re still in for a fairly hot and humid day, the first real widespread one for the region this late spring. After that cloud layer thins and dissipates, we’ll have a fair amount of sun, but some high cloud areas from upstream thunderstorms can move in later. For the WHW, the timing of an approaching cold front is late to optimize the opportunity for widespread big thunderstorms. The atmosphere will be quite unstable and a fairly healthy low for this time of year will be passing to our north, but timing \/ frontal position dictates that the most likely area for a solid or broken line of storms to form will be over NY State moving into VT and western MA \/ CT late-day \/ early evening. A few advanced isolated to scattered storms can occur ahead of this, but coverage would be less, into western portions of the WHW region (around the CT River Valley). I suspect whatever is left of the line will make its way in broken and weakening fashion across the rest of the region during the mid to late evening hours. A few of the storms can last longer (stronger cells that find a way to survive – outflow boundary regeneration, interaction with other boundaries, etc – which are things we can only now-cast by watching radar). Once the cold front moves through the region a couple hours either side of midnight west to east, the storm threat will come to an end, and a drier air mass will arrive. A tweak to this forecast update regarding Friday is to remove the shower and thunderstorm chance – the reason being the most unstable area in response to the disturbance passing by will be well to the west and southwest and I don’t expect more than fair weather clouds, a gusty breezy, drier air, but still warm temps. We welcome summer official with the occurrence of the solstice at 10:41p.m. on Friday. Looking into the weekend, you’ve heard talk of a complex of thunderstorms forming Friday night in the upper Plains \/ Midwest. I still think this will be the case. But first, we may see some debris cloudiness in the area from a small complex ahead of that one passing through our sky early Saturday, a day that otherwise looks dry and pleasantly warm. It’s that night that clouds arrive from the larger complex of storms as it exits the Great Lakes and moves through Upstate NY, adjacent southern Canada and into northwestern New England. In decaying state, it can send some showers and thunderstorms with gusty winds through our region sometime in the 3:00 a.m. to 9:00 a.m. time window of Sunday – timing and details to be tweaked further on this. The remainder of Sunday would be similar to Friday – breezy, dry, and warm. Looking ahead to Monday, it heats up again with a 90+ high temp potential. However a weak pressure gradient leaves the coast vulnerable to sea breezes, so it may be a “not-so-fast” kind of deal on the heat for the coast. Will watch that as it’s still several days away.<\/p>\n\n\n\n
TODAY: Clouds give way to sun through mid morning. Sun dominant late morning to mid afternoon. Cloud\/sun mix later on. Isolated to scattered thunderstorms possible southwestern NH, central MA, and adjacent CT late afternoon \/ early evening. Highs 80-87 South Coast, 88-95 elsewhere. Dew point 65+. Wind SW 5-15 MPH, a few higher gusts.<\/p>\n\n\n\n
TONIGHT: Variably cloudy. Scattered to isolated showers and thunderstorms west to east this evening. Clearing overnight. Lows 61-68. Dew point 60+ evening, falling to 50s overnight. Wind SW 5-15 MPH, higher gusts, shifting to NW from west to east.<\/p>\n\n\n\n
FRIDAY: Sun\/cloud mix. Highs 78-85. Dew point falls below 60. Wind NW 5-15 MPH, gusts 20-25 MPH.<\/p>\n\n\n\n
FRIDAY NIGHT: Mostly clear evening. Partly cloudy overnight. Lows 57-64,. Wind NW 5-15 MPH.<\/p>\n\n\n\n
SATURDAY: Partly cloudy morning. Mostly sunny afternoon. Highs 78-85. Wind NW 5-15 MPH.<\/p>\n\n\n\n
SATURDAY NIGHT: Clouds arrive. A shower or thunderstorm possible overnight, mainly north and west of Boston. Lows 60-67. Wind W 5-15 MPH, higher gusts.<\/p>\n\n\n\n
SUNDAY: Lots of clouds early with a shower or thunderstorm possible Boston area southward, then mostly sunny. Highs 80-87. Wind W 5-15 MPH, higher gusts.<\/p>\n\n\n\n
SUNDAY NIGHT: Mostly clear. Lows 62-69. Wind SW up to 10 MPH.<\/p>\n\n\n\n

DAYS 6-10 (JUNE 24-28)<\/p>\n\n\n\n
Brief heat spike expected June 24 but again watch for a cooler coast. Back-door front should cool the region down, maybe with a passing shower or thunderstorm briefly otherwise mostly fair weather middle of next week. Isolated showers \/ storms as warmer air tries to return later next week.<\/p>\n\n\n\n
DAYS 11-15 (JUNE 29 \u2013 JULY 3)<\/p>\n\n\n\n
General west northwest flow pattern with a a couple disturbances to pass by. These can bring a few showers and thunderstorms, but most of the time looks rain-free with variable temperatures averaging near to above normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
