.DISCUSSION...
Key Message:
- Cloudier forecast Wednesday for areas mainly south/east of
  Albany along with a few showers possible (20-30%).
Discussion:
As of 135 PM EDT, mostly sunny skies continue across the region
with temps warming into the mid 60s to lower 70s. Expect max
temps to increase from current levels by about 3-5 degrees in
most areas.
Generally dry weather is expected through Friday with the
exception of late tonight and Wednesday, as a wave of low
pressure tracks off the eastern seaboard. Some low level
moisture is expected to track north and west of this passing
low, with clouds and spotty light showers/sprinkles possibly
extending as far north and west as the mid Hudson Valley and
Litchfield Hills around or shortly after daybreak. Some of these
showers could even extend as far north and west as the Capital
Region, Berkshires and Schoharie County during the mid to late
morning hours before ultimately decreasing in coverage during
the afternoon hours. So, a cloudier forecast for tomorrow for
areas from Albany south and east, along with the possibility for
a few showers (mainly during the morning hours).
Another cool night tonight, with lows in the 40s for many areas
with some mid/upper 30s possible across portions of the southern
Adirondacks. High temperatures Wednesday should be warmest
across the Mohawk and upper Hudson Valleys where more sunshine
is expected, with highs reaching 70-75. Cooler to the south and
east high high temps mainly in the 60s to around 70.
Fog development may be a bit greater in coverage for areas south
of I-90 Wednesday night due to slightly greater boundary layer
moisture/less daytime mixing on Wednesday.
Generally dry for Thursday through Saturday morning, despite a
cold front dropping southward Thursday. An approaching frontal
system and upper level disturbance could bring a few showers
late Saturday into Monday, although there remains uncertainty
regarding the exact track/evolution of the upper level energy
associated with this system and therefore expected coverage of
showers. Otherwise, temperatures will be near or slightly below
normal, with daytime highs mainly in the 60s and 70s, and
overnight lows in the 40s to lower/mid 50s.
