.SYNOPSIS...
Storm system will be slowly departing the region today and tonight,
with low chances of rain showers mainly across the higher terrain
this afternoon. Dry conditions will prevail elsewhere, with
temperatures generally above normal. A coastal system may bring rain
showers across the Mid Hudson Valley and northwest Connecticut
this weekend, though most will stay dry with a trend towards
cooler temperatures for early next week.

.DISCUSSION...
Key Messages:
- Mainly dry today with a low chance of rain showers (10-30%)
  mainly across the high terrain this afternoon.
- Outside of a low chance of rain showers (10-30%) Saturday night
  and Sunday, mainly dry conditions through mid next week.
- Above normal temperatures through Monday, trending near normal
  by mid next week.
As of 130 AM...03z surface analysis depicted a weak surface low
centered across western New England along a stationary boundary.
Rain showers have exited the area, though low stratus remains
in place outside of river valleys, where downsloping has
promoted clearing skies. As of 100 AM, temperatures were fairly
mild with values ranging from around 60 across the high terrain
to the mid/upper 60s in river valleys.
For today and tonight, much of the area will be dry with the
system`s departure to our east and high pressure slowly building in
from the Great Lakes. A trailing positively tilted 500 hPa shortwave
will be moving across the region later this morning into the
early afternoon, with increasing CVA accompanying it.
Steepening lapse rates aloft and lift from the CVA will drive
isolated to scattered diurnal rain showers early this afternoon,
especially across the higher terrain of the ADKs and southern
Greens. Any rain that falls will be light at only a few
hundredths. It will remain fairly mild and muggy (dewpoints in
the 50s/60s) with weak northwest flow, and highs today should
easily climb into upper 60s (terrain) to upper 70s (valleys).
Lows tonight will only fall into the upper 40s (terrain) to mid
50s (valleys).
For this weekend, dry conditions will prevail for the daytime
Saturday with high pressure continuing to build over the region.
For Saturday night into Sunday, a weak shortwave moving across
the Mid Atlantic from the Southeast U.S. will drive increasing,
but low rain chances (10-30% per latest NBM) mainly for areas
south and east of the Capital District. This is low confidence
overall and is mainly being driven by the more aggressive
deterministic GFS, with the EC/CMC keeping most precipitation
across the Mid Atlantic into southern New England. Regardless,
continue to monitor the latest forecasts. Outside of these
regions, it will remain dry with continued mild temperatures in
the 60s/70s during the daytime, and overnight lows in the
40s/50s.
For early next week, mid and upper level ridging will become
more entrenched across the Great Lakes into the Northeast,
promoting continued dry weather with strong surface high
pressure building into southern Ontario and Quebec by next
Tuesday/Wednesday. In addition, a reprieve of our above normal
temperatures will arrive by Tuesday as a cold front passes
through the region. Highs in the 60s/70s and lows in the 40s/50s
are expected for Monday and Tuesday, and are projected to fall
for Wednesday with highs in the 50s/60s and lows in the 30s/40s.
Some frost is possible by the late week for the high terrain
and outlying areas.

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
We start the TAF period with a variety of flying conditions as
patchy fog and low level clouds continue to develop at the start of
the 06z timeframe. Through 12z this morning, VFR/MVFR/IFR conditions
fluctuate due to low ceilings as low level clouds continue to move
through KALB, KPOU, KGFL, and KPSF. For patchy fog development
between 8z and 10z, LIFR/IFR/MVFR conditions fluctuate due to low
visibility. Patchy fog and low level clouds should begin to diminish
between 12z and 16z. VFR conditions return between 16z and 18z.
Light and variable winds this morning increase this afternoon
between 3 and 8 knots, becoming northwesterly to northerly.
