.DISCUSSION...
Key Messages:
- Low chance of rain showers (20-30%) Saturday night/early
  Sunday mainly south/east of Albany, otherwise mainly dry
  conditions through late next week.
- Above normal temperatures through Tuesday, trending to below
  normal by mid/late next week.
As of 130 AM...03z surface analysis depicted a broad area of
high pressure stretching form the Great Lakes into the Ohio and
Mississippi River Valleys. A stationary front was located across
northern New York and New England, with another across the
Southeast into the Chesapeake Bay. Temperatures across the
region at this hour were in the mid 50s (terrain) to around 60
(valleys).
For today, dry conditions with a mix of sun and clouds are initially
expected with the high pressure just to the west of the region.
Any breaks of sunshine will fade as clouds increase this
afternoon ahead of an approaching shortwave from the southeast
U.S.. Temperatures will remain above normal for this time of
year, with PM highs ranging from the upper 60s (terrain) to
upper 70s (valleys).
For tonight, the aforementioned shortwave will approach the
region from the south, and is progged to be centered over the
Mid Atlantic and southern New England tonight. CVA accompanying
the shortwave and moisture in place will be enough to drive
a brief, light stratiform rain mainly across the Mid-Hudson
Valley and western New England this evening into tonight, with
dry conditions expected elsewhere. Any rain that falls will be
light, with expected amounts remaining under a tenth of an inch.
Lows will remain mild in the low 50s (terrain) to near 60
(valleys).
For Sunday through mid next week, mid and upper level ridging will
become more entrenched across the Great Lakes into the Northeast,
promoting a prolonged stretch of 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 Wednesday as a cold front passes through
the region late Tuesday. Highs initially will be in the 60s/70s
with low 80s in the valleys Sunday, cooling down by Wednesday
into the 60s in valleys and 50s across higher terrain. Overnight
lows will cool into the 30s to lower 40s, though some 20s will
be possible across the southern Adirondacks/southern VT.

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
Once patchy fog diminishes at KGFL, VFR conditions return
through 28/00z. Between 28/06z and 28/12z, patchy fog could
develop once again but confidence is low to include it in the
TAFs at this time. VFR conditions continue through the TAF
period for KALB, KPOU, and KPSF. Northwest to southeast light
winds up to 5 knots continue throughout the TAF period.
