Synopsis
A cold front sweeps through the region this afternoon and
evening with scattered showers and thunderstorms. Weak waves of
low pressure will develop along the front off the south coast,
which may bring a few showers at times along with cooler
temperatures Sunday into Monday, especially near the coast.

High pressure returns Tuesday, but another approaching front
will more showers and thunderstorms Tuesday night into
Wednesday. Dry and seasonable weather follows Thursday into
Friday as high pressure builds into the region.

Near term until 6 pm this evening
* potential for strong thunderstorms which may produce localized
flooding and gusty winds from midday through early evening *
10 am update...

at 10 am showers were crossing southern vt and central nh. Per
mslp fields, this lines up well with the position of the cold
front. South of the showers the winds are south to southwest and
dews are 70-75; north of the showers winds are northwest to
north and dews are in the 60s.

Short-term guidance continues to show probable showers t-storms
crossing southern new england this afternoon and evening and
reaching the south coast around 8 pm. 09z SREF showed a 70 pct
chance of capes over 1000 j kg and 95 pct chance of this across
ct-ri-se mass. Upper winds are marginal, with 12z soundings
showing 35 kt winds at 500 mb around the area and forecast to
diminish during the afternoon. Winds at 850 mb are forecast at
20-25 kt and diminish by evening. Precip water values at chh
this morning were 2.08 inches, and similar values linger ahead
of the cold front through afternoon, then retreat south by
evening.

We will continue the forecast of showers tstms for the
afternoon evening. A few storms may reach severe damaging
levels. Moisture values continue to support local downpours as
well.

Temps aloft show 18c at 900 mb (13c equiv) and 17c at 850 mb.

This supports current forecasts of 80-85f MAX temps, but also
hints at upper 80s if sufficient clearing develops and allows
mixing up to 850 mb. Dew points 70-75 will linger until the cold
front moves through.

Short term 6 pm this evening through 6 pm Sunday
Tonight and Sunday...

the cold front will ride along or just off the south coast
tonight. Low pressure waves will move along the front, which
will keep chance for precip going. However, most of the
instability pushes offshore. Still noting k indices in the
lower-mid 30s tonight, so can't totally rule out any
thunderstorms, but will not be as strong. Pwats will slowly fall
across central and northern areas, but will linger at around 2
inches along the S coast, so might see some downpours there off
and on through the night. Temps will bottom out from 60-65
across the higher inland terrain, ranging to near 70 along the
immediate S coast.

With the weak waves of energy moving along the nearly
stationary front to the S on Sunday, will still see scattered
showers and maybe a thunderstorm or two during the day. It will
still be rather humid with dewpoints in the lower-mid 60s,
highest S of the mass pike. Temps will be cooler though, only
topping off at 70 to 75.

Long term Sunday night through Friday
Highlights...

* mainly dry Mon Tue with temps a bit below normal. Low risk for a
shower near the coast mon
* increasing humidity with showers and sct t-storms Tue night wed
* mainly dry and seasonable Thu into Fri with comfortable humidity
Sunday night into Tuesday...

weak wave of low pressure tracks south of new eng from the mid atlc
coast through Monday. ECMWF has trended south and is now more in
line with GFS nam keeping deepest moisture south of new eng.

However, northern extent of deeper moisture may reach SE new eng
where pwats still around 1.5 inches. As a result can't rule out a
few showers across ri and SE ma, especially Sun night into early
mon, then drying as low pres pulls away and high pres noses down
from maine. On tue, mid level ridging briefly moves into the region
with high pres in control. Temps a bit below normal Mon Tue with
easterly flow persisting.

Tuesday night into Wednesday...

upstream mid level trough approaches from the west with attending
cold front expected to sweep across the region wed
afternoon evening. Pwat plume ahead of the front increases to 2+
inches combined with moderate instability and modest forcing for
ascent will result in a period of showers and sct t-storms moving
through sometime later Tue night into wed. Pwat and low level wind
anomalies 2+ sd above climo which indicates potential for some heavy
rainfall. A return of 70+ dewpoints likely.

Thursday into Friday...

cold front will be offshore by Thu with high pres and drier airmass
moving into the region. Expect dry weather and seasonably warm temps
with comfortable humidity levels as dewpoints may fall into the
50s.
