Area Forecast Discussion
National Weather Service Boston/Norton MA
202 PM EDT Tue Mar 26 2019

.SYNOPSIS...
High pressure will build across the region through Wednesday
with seasonable, 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 /UNTIL 6 PM THIS EVENING/...

130 PM Update...

Except for a few wisps of high clouds across E Mass into RI,
skies were mainly clear at 17Z. Also noting some lower clouds
in the N-NE flow across the southern coastal waters as seen on
latest GOES-East Visible satellite loop.

N-NE winds remain gusty across Cape Cod, up to 21 kt at KMVY and
26 kt at KACK. Away from SE Mass and RI, noting winds have
become N-NW though remaining at around 10 kt or so. Very dry
airmass remains across most of the region, with dewpoints in
the single digits though they remain in the mid to upper teens
across E RI/SE Mass with the N-NE winds in place. Noting patchy
lower clouds across portions of the outer Cape as well.

With the N-NE wind gradient along the immediate E coast, will be
tough to kick any sea breeze. However, if winds do diminish
enough later this afternoon, could see the hint of a brief sea
breeze for a couple of hours.

Have updated the near term to reflect current conditions.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...

Tonight...

Chilly again. Dome of high pressure more influential, light
winds and mostly clear conditions. Leaned with coldest forecast
guidance mainly consisting of MOS guidance that has undergone
bias correction. Looking at lows around 20 degrees for most of S
New England.

Wednesday...

Beautiful day. Beneath high pressure, light winds becoming S,
abundant sunshine, slightly warmer aloft, looking at highs
around the mid to upper 40s with another day of very dry
conditions, dewpoints back down into the single digits with
boundary-layer mixing. Keep the lip balm on hand.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...

Highlights...

* Dry weather prevails much of this time period
* Warming trend from Thursday through Saturday
* Low risk of showers Thu night/Fri morning, then again
  sometime Saturday night into Monday morning

Thursday through Saturday...

High pressure should move farther out to sea Thursday, which will
permit a cold front to approach southern New England towards
daybreak Friday. Above normal temperatures expected during this
time. rainfall chances will be scattered at best and mainly confined
towards northwest Massachusetts, at least until a low pressure moves
through the Great Lakes Saturday. It is possible a secondary low
pressure develops more towards our region Saturday night as this
system passes by. This would lead to a more widespread, but still
light, rainfall. Have only moderate confidence in the timing of
rainfall chances during this portion of the forecast.

Sunday into Monday...

Expecting Sunday to be another transition day, not atypical of
Spring. As a weak low pressure passes by, our warming trend is
snapped and we start trending toward lower temperatures. Still
thinking temperatures will be above normal, but noticeably colder
conditions by Monday when compared to the warmth of Saturday. High
pressure building in from the west should mean drier weather
developing from west to east on Monday.
