&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
1020 PM Update:
Key Messages:
* Severe weather threat has passed.
* Overcast with periods of rain showers for the overnight.
Threat of severe weather is over. Expect periods of rain with a
few in-cloud flashes/rumbles of thunder possible tonight as the
cold front itself becomes increasingly slows or becomes stalled
out somewhere near or in vicinity of the I-95 corridor. Overcast
and cooler temps for the overnight to early Sunday morning
period, with lows in the mid to upper 50s.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
Key Messages:
* Rain showers linger into Sunday morning, especially across eastern
  MA.
* Cooler temps arrive to start off the week.
Sunday and Sunday Night...
Rain showers continue into Sunday morning, with pockets of
moderately heavy rainfall at times, as an anafrontal wave lingers
over southern New England. At this time, expecting heaviest rain
across and southeast of I-95. Rain should move out to sea by late
afternoon or early evening, but the interior should start drying out
late morning or early afternoon. Given the lingering cloud cover and
rain, expecting afternoon high temps to remain in the mid to upper
60 and struggle to reach 70 (with the exception of the outer Cape
and Islands... in the low 70s).
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
Key Messages:
* Mainly dry and pleasant for much of next week with cool night and
  mild days
* Offshore low may graze coast midweek, bringing chance for a few
  showers Wednesday
Once the rain and storms from the weekend clears with the exit of a
cold front, high pressure builds in over the region once more. 925
mb temperatures generally sit around or just below 10C for the
mornings, then getting to around 15C for daytime temperatures. Highs
through much of the week will likely be mostly in the 70s with some
areas in the upper 60s. A brief warmup over the region is possible
heading into Thursday as 925 mb temps get close to 20C and ensemble
probs for surface temperatures greater than 75 around 50% or higher;
the GEFS has probabilities over Boston, SE MA, and the river valleys
around 20% for temperatures at or above 80F. This warmth will be
short-lived though as another cold front pushes its way through the
region, ushering cooler temperatures in for Friday. Ensembles
indicate that some below normal temperatures may settle into the
region for the end of the week in its wake with highs in the 60s for
most (lower 70s for the CT River Valley).
Much of this period looks quiet aside from a low passing offshore
midweek. This may bring a chance for some showers into eastern MA,
RI, and the Cape and Islands Wednesday through Thursday night.
