Synopsis
Tonight will be fair and cool as high pressure builds in. Tuesday
will be sunny, warm and dry as high pressure briefly crests over the
region. Showers and thunderstorms are likely again on Wednesday as a
warm front crosses the area. A strong cold front will cross the area
on Thursday with fair and cool weather following for Friday into the
weekend.

Near term through Tuesday night
As of 10:31 pm, a quiet evening after 3 days of getting pounded
with thunderstorms. Some patchy strato CU clouds across the
central part of the area along a theta-e boundary. Some high
cirrus clouds over the southern 3 counties. Winds are mainly
light and variable. Temperatures range from the upper 50s in the
western adirondacks to the mid 70s in the capital district.

Mainly clear skies expected tonight with winds diminishing
after midnight should allow for good radiational cooling. Some
patchy fog expected. Lows in the mid 50s to mid 60s.

Previous...

Tuesday will be a sunny and dry day as high pressure builds in
at the surface. High temperatures will range from the upper 70s
in the high terrain to the mid 80s in the valleys. Tuesday night
we will see an increase in low level moisture and cloud cover
as return flow sets up ahead of the next upper level
disturbance. A few showers may even make it into the southern
portion of the forecast area prior to daybreak. Overnight lows
will generally be in the upper 50s to mid 60s.

Short term Wednesday through Wednesday night
Humidity returns on Wednesday as anonymously strong 850mb
southwesterly winds usher in pwats nearing 2.0 inches.

Continued moisture advection along with dynamic lift associated
with low-amplitude waves ahead of the main trough should
contribute to scattered to numerous showers and thunderstorms
through the day. Given the strengthening wind field and rich
boundary layer moisture, there is certainly severe weather and
heavy rainfall potential, although the details remain murky.

Degree of instability will depend on whether any breaks in the
clouds and showers can occur during the morning to early
afternoon hours. Some lingering showers and thunderstorms will
be possible Wednesday night with respectable deep moisture
lingering and main area of height falls still off to the west.

Mild again with lows mainly in the 60s.

Long term Thursday through Monday
A cold front slowly moving through the region on Thursday will keep
chances for scattered showers and some storms in the forecast for
the early part of the long term. Then, we should transition to a
mainly rain-free and cooler less humid air mass for the weekend into
possible the first half of the new work week as a strong canadian
high pressure takes control of region. Read on for details.

A cold front will be gradually sliding through eastern ny and
western new england on Thursday as guidance continues to show an
intensifying closed low in quebec with our strong closed bermuda
high firmly in place over the central atlantic. The intensifying
upper level low looks to strengthen the associated surface low over
southern canada which should slow down the progression of our front,
especially as it runs into the semi-permanent bermuda high over the
atlantic. Members of the global guidance all show sufficient 700mb
moisture riding along the boundary, especially in the afternoon, so
we continued to place chance pops for showers and some storms in the
forecast for Thursday with the highest probabilities over the mid-
hudson valley and NW ct which should be closer to the front. We
continued the low end chance pops even into the adirondacks due to
uncertainty in the timing and placement of the progressing cold
front. However, future updates may trend drier should the front exit
quicker through our cwa. Temperatures along and south of the
boundary should be in the low to mid 80s with dew points still high
enough to make it feel muggy. Areas north and west of the capital
district should be a few degrees cooler and less humid as these
spots feel the effects of the encroaching canadian high.

The ECMWF is still the slowest member of guidance with the front's
departure as it continues to show the front and potential for
precipitation lingering into Thursday evening. The GFS and cmc-nh
are still faster and show it exiting by or shortly after 00z Friday.

For now, we continue to linger chance pops for the first half of
Thursday night, mainly for areas south and east of the capital
district, as the cut off low looks to be positively titled and a
shortwave at the base of the trough which should be the "kicker" is
still far to west by 00z Friday over the great lakes. This shortwave
should progress eastward overnight and become absorbed within the
main parent trough.

By 12z Friday, the main trough axis should be traveling across the
northeast with a wind shift to the northwest ushering in a much
cooler and less humid air mass. We show a dry forecast for Friday
through Sunday as the upper level low should kick our front out to
sea allowing a large scale canadian high to take control of the
region. While the trough axis could spark a few isolated to
scattered showers over the adirondacks and upper hudson valley on
Saturday or Sunday, we left a dry forecast due to limited 700mb
moisture. Should this chance increase, we may increases pops for the
higher terrain areas. Best chance for showers under the cold pool
looks to be Saturday. Otherwise, expect a seasonably cool and less
humid air mass to be over the region through Sunday with high
temperatures staying in the 70s (60s catskills, greens, berkshires
and adirondacks) and cool overnight lows in the 50s (40s higher
terrain).

Ridging builds aloft heading into Monday as our upper level low
should exit out to sea and surface high pressure maintains control
and a dry forecast. Again, ecwmf is the most aggressive and keeps
the parent cut off low over new england but this seems to be an
outlier. Temperatures should warm up a few degrees with highs
ranging from the mid 70s to low 80s. Overnight lows should also turn
a bit milder as well, only falling into the mid - upper 50s to near
60.

Aviation 03z Tuesday through Saturday
High pressure will build across the TAF sites tonight into
Tuesday. MainlyVFR conditions forecast through the TAF period
ending 21 00z. Exception will be ground fog late tonight at
kgfl.

Low probability for ground fog at kpsf, but did not include in
taf as a secondary front passing through late tonight should
keep airmass stirred up enough to keep fog from forming.

West to northwest winds will decrease to 5-10 kt after sunset,
and become light variable after midnight. Winds will be light
and variable on Tuesday.

Outlook...

Tuesday: low operational impact. No sig wx.

Tuesday night: moderate operational impact. Chance of
shra... Tsra.

Wednesday: high operational impact. Likely shra... Tsra.

Wednesday night: moderate operational impact. Chance of
shra... Tsra.

Thursday: moderate operational impact. Chance of shra... Tsra.

Thursday night: low operational impact. No sig wx.

Friday: low operational impact. Breezy no sig wx.

Fire weather
Tuesday will be a dry day as high pressure briefly builds into
the region. Showers and thunderstorms will become likely again
on Wednesday as above normal warmth continues. The weather turns
drier and milder for the end of the week.

Hydrology
A few isolated storms are possible across litchfield county this
evening. Any storm will be capable of locally heavy downpours
leading to minor urban poor drainage flooding.

After a dry day Tuesday, anomalous moisture returns for
Wednesday. Scattered to numerous showers and thunderstorms are
likely for much of the day. Again, urban poor drainage flooding
is possible, and isolated flash flooding cannot be ruled out.

It will trend drier for the end of the week.

and forecast river stages and lake elevations, please visit the
