Synopsis
A coastal storm will track well out to sea tonight. High
pressure builds in from the west Tuesday into Wednesday with
cool and dry weather. A weak cold front may bring a few showers
Thursday night, otherwise moderating temperatures Thursday into
Friday. Mild weather next weekend, but low pressure may bring a
period of rain sometime late Sunday into Monday with much cooler
weather possible by Monday.

Near term through tonight
Mid level shortwave moves to the mid atlc coast tonight with
coastal low pres tracking well south of new eng. This shortwave
will keep mid level cloud shield near the south coast for at
least the first half of tonight and it may even push a bit to
the north, before moving offshore late tonight. However,
northern stream shortwave dropping into northern new eng with
w NW flow aloft will keep deeper moisture to the south. There is
a low risk for a few sprinkles or light showers this evening
from bid to ack, otherwise dry.

Good radiational cooling, especially north of the pike where
clear skies will prevail. Lows will drop into the teens and low
20s here. More clouds along the south coast where expected lows
will be in the upper 20s.

Short term Tuesday through Tuesday night
Tuesday...

mid level shortwave moves south across sne, but airmass is bone
dry as high pres builds in from the west. Pwats dropping to less
than 0.1" with dewpoints down into the single numbers. Other
than a few high clouds, a sunny day expected but chilly with
temps 5-10 degrees below normal. High upper 30s to lower 40s.

Tuesday night...

high pres moves into new eng setting the stage for a cold night
with clear skies and light winds. Lows away from the immediate
coast will drop into the teens, with 20s along the coast.

Long term Wednesday through Monday
Highlights...

* dry weather prevails much of this time period
* gradual warming trend Wed & Thu then 60s possible fri-sun
* low risk of showers Thu ngt Fri am then again Sat night sun
Wednesday...

pleasant day on Wednesday as a 1034mb surface high moves over the
region. Winds back to the southwest behind the low bringing
moderating temperatures, into the mid-upper 40s (less along the
south coast). Light winds and sunny skies will make it feel spring
like.

Thursday and Friday...

Thursday the high exits to the east and we'll be sandwiched between
it and a passing surface low mid-level shortwave over southeast
canada. This increases the pressure gradient and makes for a breezy
but warm day Thursday as southerly winds continue to advect warmer
air northward. Highs should reach into the 50s save for the south
coast CAPE cod where strong onshore flow over the cold ocean waters
keeps temps in the 40s. As this low moves east it drags a cold front
across northern new england. Given the northward placement of the
parent low and recent model trends, there looks to be less of a
chance that we see the front hold together through much if any
of southern new england. Thus, not expecting widespread rains,
but more scattered shower chances Thursday night, best in nw
mass. Neither will we see much of a temperature drop; lows
remain quite warm in the upper 30s to near 40.

Friday attention turns to a low which forms in the lee of the
rockies early Friday and moves through the ohio valley to the great
lakes region by Saturday morning. We'll stay dry under a brief, weak
high pressure, keeping the warming trend going. Highs on Friday
reach into the upper 50s to near 60, except, again, along the south
coast where onshore flow holds temps in the upper 40s low 50s.

Saturday and Sunday...

strong WAA Friday night through at least Saturday. With 925mb temps
approaching 12c, temps should reach well into the 60s, and even
touch 70, especially in northeast ma. As the low approaches, the
pressure gradient tightens and southwest winds will be breezy
through the day. Good surface heating should make for a well mixed
bl and with a 35-40kt LLJ we could see gusts 25-35 mph mixing down.

Big question will be timing of the cold front rain chances. Trending
the forecast to the slower ec solution which has been more
consistently showing a late Sunday early Monday passage. Overall the
better of the two weekend days right now looks to be Saturday, with
increasing rain chances during the day on Sunday ahead of that cold
front. However, at this time period, still plenty of room for
changes.
