.SYNOPSIS...
Warm and breezy weather conditions expected today, with
scattered showers arriving later this afternoon and evening.
Drier and mild behind a cold front Sunday. Low pressure should
pass by to our north Tuesday. High pressure then expected to
linger nearby into Friday with above normal temperatures.

&&

.NEAR TERM /THROUGH TODAY/...
Key Messages:

* Very warm and breezy with high temperatures well into the 70s
  to lower 80s, despite filtered sun.

Persistent southwest winds will keep pushing warmer air towards
our region. Despite some clouds today much of southern New
England should get an early taste of summerlike warmth. The
exception will be along the south coast, including the Cape and
islands. Ocean temperatures are still in the mid 40s, which will
prevent much of the immediate coast in the 60s, with some 50s
possible across the Cape and islands due to more ocean exposure.

Mainly dry to start the day. A weak mid level shortwave and a
accompanying surface trough ahead of an approaching cold front
should help to generate scattered showers this afternoon into
this evening. The forcing is not particularly strong, but there
is modest precipitable water values later today. Not expecting a
washout, but there is at least a chance for a few hundredths of
rainfall across the western 2/3 of southern New England.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM SUNDAY/...
Key Messages:

* Cold front brings passing showers early tonight, but with
  cooler conditions and gusty NW winds up to 45 mph for
  overnight.

Details:

A cold front then arrives for early evening. Once this front
passes by, the arrival of drier air should bring and end to any
showers. Anticipating all of our region to be dry by around
midnight, with many areas dry earlier than that.

The presence of the cold front will maintain gusty conditions,
even as winds become west to northwest. Still expecting wind
gusts of 25-40 mph, with the highest gusts over the higher
terrain. Outside chance that NW gusts across the higher terrain
could get to around 45-50 mph. No current plans for Wind
Advisories at this time, but will continue to monitor.

High pressure starts to arrive for Sunday. Thus, winds will
start to diminish through the day. Dry conditions expected with
near normal high temperatures.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Key Messages:
* Dry for much of Monday with light winds.
* Showers Monday night into Tuesday and another round Friday.
* Temperatures next week slightly above normal.

Monday through Tuesday:

A brief upper level ridge shifts over southern New England for
Monday yielding light NW winds. Winds likely switch to onshore
(SE) flow along the coastline in the afternoon at 6-12 mph.
Temperatures trend slightly cooler than Sunday with highs in the
50s closer to the coastline and low 60s across interior southern
New England. It will be dry much of the day with showers likely
not arriving until Friday night. Although there is a low chance
(< 20%) for an isolated shower in the early evening timeframe.

A round of showers move through Monday night into Tuesday with
light rainfall amounts expected. Tuesday likely stays unsettled
for the morning, as any remaining showers exit off to the east,
followed by gradually drying conditions behind it in the
afternoon. Weak warm advection will bring 850mb temperatures in
the 6-10C range Tuesday. This will support above normal
temperatures in the 60s and lower 70s with the exception of the
Cape/Islands in the 50s.

Tuesday Night through Friday:

A cold front moves through Tuesday night into early Wednesday
morning. This will bring a slightly cooler airmass in for
Wednesday, but still slightly above normal with highs in the 60s
in most places. Similar pattern stays in place through the end
of the week with zonal flow and 850mb temperature anomalies
signaling slightly above normal temperatures. Ensemble guidance
shows a signal for a more unsettled pattern Friday into the
weekend with potential for periodic chances for precipitation.

Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.

Small Craft Advisories for all waters at some point today into

exposed coastal waters. May need to extend advisories for some
waters due to marginal wind gusts up to 25 kt, but do not yet
have enough confidence to do so at this time. A cold front
approaches the waters towards midnight, then moves farther
offshore Sunday. Good visibility expected.

5 ft.
