SYNOPSIS
A more seasonable day on Friday, along with dry conditions during the daytime hours. A cold front brings another round of showers overnight into early Saturday morning. Dry for the rest of Saturday and all day Sunday with breezy conditions both days.
The dry stretch of weather continues as we head into early next week, with the next chance for unsettled weather being Wednesday.
NEAR TERM /UNTIL 6 AM THIS MORNING/
935 PM Update...
* Considerable cloudiness overnight...lows upper 30s/lower 40s
The last of the light showers/sprinkles from a mid level cloud deck across far southeast MA will be exiting the region in the next 1-2 hours. This is response to the deamplifying shortwave moving east of the region. So while dry weather will prevail for the overnight hours...mid level cloud deck will be stubborn given there is not a strong push of dry air and low level winds will remain onshore. A few breaks are possible in the clouds...but expect a fair amount of clouds to hang tough overnight. This should hold overnight low temps in the upper 30s to the lower 40s.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/
345 pm update...
Highlights:
* Slight improvement for Friday with drier weather for the daylight hours and near seasonable temperatures.
* Unsettled overnight with another chance for light rain, especially along the south coast near daybreak on Saturday.
Some improvement weatherwise on Friday with surface high pressure expanding into southern New England, along with mid-level ridging. A warmer, more seasonable day with highs in the upper 50s and low 60s are on tap. Where temperatures may struggle are along the immediate coast as the winds are still coming off of the water. Areas of low clouds to start gives way to breaks of sunshine late morning into early afternoon, short-lived as mid and high clouds move in from west to east ahead of a cold front. Winds are more or less out of the southeast due to the flow from the surface high based in eastern Quebec and surface low well off to the south near Bermuda. The pressure gradient eases allowing for gusts less than 20 MPH at the coast.
Increasing clouds from west to east during the second-half of the day ahead of an approaching front. A prefrontal trough could set off a few showers across western Massachusetts and northern Connecticut late afternoon, but do think the bulk of any perception will come with the frontal passage overnight, then kick off shore shortly after sunrise on Saturday. That said, do not anticipate a soaking rain, much of southern New England receives a few hundredths of an inch, and the immediate south coast, Cape, and Island receive around a quarter to a third of an inch.
Wind shifts overnight from southeast to southwest, no strong gusts are expected. Overnight lows dip into the middle 40s.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
345 pm update...
Key Point: * Fire weather concerns this weekend through Tuesday
Fairly high consistency amongst the 12z global guidance runs as well with prior runs. So that results in overall higher than average confidence. In general, most of us will consider the weather for most of the period to be pretty nice. A weak front will be moving offshore during the first part of Saturday, only bringing a few light showers. Behind the front, a much drier airmass will be spreading in. So that will result in clearing skies. Have again blended in the warmer side of guidance for temperatures and lower side of guidance for dewpoints. Forecast soundings still show excellent mixing (5000-6000ft) developing in the afternoon along with westerly winds. Being still a "pre- greenup" phase of vegetation, that usually means temperatures overachieve and humidity levels go lower than most guidance thanks to the combo of downsloping and deep boundary layer mixing. We should see widespread mid 60s for highs, perhaps making a run at 70F in the CT River Valley.
Sunday will be similar, though with 850mb temperatures slightly cooler (down around -1C vs +1C on Saturday), daytime highs will be a few degrees cooler, primarily either side of 60F. Again deep boundary layer mixing (6000-7000ft) will act to bring down some of the 25kt winds aloft along with dry air. Thus winds will be gustier than on Saturday and lower dewpoints. The combo will mean we will be flirting with some of the fire weather thresholds (RH <30%, Frequent gusts >25mph, less than 1/4" of rain in 3 days).
Monday, high pressure will move overhead and maintain the dry weather. Still a dry airmass and deep mixing, but winds will be weaker, so will still need to monitor fire weather aspects, but don't think it's as significant a concern. Tuesday will still be dry, but with high pressure moving off the east coast, winds will start to turn southerly.
Guidance showing another weak front coming through Wednesday, so stuck with NBM PoPs. Rainfall amounts again will be light. Dry weather should return for Thursday.

An approaching cold front will bring a period of MVFR-IFR conditions late tonight into Sat morning. This will also be accompanied by several hours of showers with a few downpours too. Most locations should see conditions improve to VFR by early Saturday afternoon...but this process may take a few hours longer towards the Cape and Islands. S winds 5 to 10 knots tonight becoming W at 10 to 15 knots by Sat afternoon. A few gusts in the 20 to 25 knot range may also develop across the interior by mid to late afternoon.

Tonight and Friday...High confidence.
Pressure gradient weakens as the wave of low pressure continues to move further southeast and away from the region. Seas will also diminish, but some 5 foot seas to linger across our southern outer- waters, extending small craft headlines in those locations through Friday late afternoon. Winds on Friday remain out of the east and less than 20 knots.
Friday Night...High confidence.
Wind direction from southeast to southwest with the passage of a frontal boundary, along with rain chances. Areas of fog is possible with reduced visibilities. Seas remain below 4 foot.
