.DISCUSSION...
KEY MESSAGE 1...

Gusty southwest winds will develop today reaching 25-35 mph.
Temperatures will rise into the 60s to lower 70s this afternoon.
Relative humidity values will lower into the 35 to 40 percent
range for valley areas from Albany and points south and east
and 40 to 55 percent elsewhere. Per coordination on Sunday, a
new Special Weather Statement for an elevated risk for fire
spread has been issued for areas from Albany south and east
across the mid Hudson Valley, eastern Catskills,
central/southern Taconics and for Berkshire County in MA and
Litchfield County in CT.

It will turn even warmer on Tuesday with highs in the 70s to
lower 80s with a continued south to southwesterly breeze.
However, dewpoints will be rising into the upper 40s to mid-50s
leading to relative humidity values only lowering into the 40 to
55 percent range for most areas (except some spotty 35 percent
values in the mid-Hudson Valley). Will coordinate whether or not
any Special Weather Statements are needed on Tuesday.

KEY MESSAGE 2...

Following a mostly dry day today, unsettled weather arrives for
Tuesday and Wednesday of this week. Southwesterly upper level
flow will set up across the region with occasional shortwaves
passing through the flow. The next shortwave crosses the region
early Tuesday morning which could bring a shower or two to some
areas. A break in precipitation is expected during the midday
hours as it turns quite warm. A cold front will begin to cross
New York state during the afternoon. Forcing will be limited
ahead of the front, so shower and thunderstorm development for
the afternoon hours may be more limited to within the vicinity
of the front, which will be for areas north and west of Albany.
Within this region, instability will not be particularly strong
(CAPE values less than 1000 J/kg) though 0-6 km shear values
will be in the 30 to 40 kt range. For any taller cores that can
develop, strong to locally damaging wind gusts and some hail
cannot be ruled out. The Storm Prediction Center has areas north
and west of Albany outlooked in a marginal risk for severe
thunderstorms for Tuesday afternoon. The severe threat will
diminish after dark as the front continues to push eastward
bringing some rain showers to areas farther south and east.

Another wave of low pressure will track northeastward along the
front through the region on Wednesday. This looks to bring a
fairly widespread steady rainfall for much of the day. It will
be a cooler day due to the clouds and rain with temperatures
only in the 50s and 60s. A general lack of instability should
limit thunder potential on Wednesday.

Expected rainfall amounts (combining Tuesday and Wednesday) are
between 1 and 1.50 inches for areas north and west of Albany to
0.50 and 1.00 inches from Albany and points south and east.
Where any thunderstorms develop on Tuesday, some higher rainfall
amounts can occur. Overall, this rainfall should not lead to
any significant hydrologic issues but keep any future fire
weather issues at bay.

The upper trough looks to advance eastward over our region on
Thursday, quicker than previous days. This will result in the
overall storm track to be displaced farther to the south and
east and a trend toward drier weather on Thursday. However, the
placement of the upper trough and any passing shortwaves could
lead to some isolated to scattered showers on some days later
this week through next weekend. Temperatures also return to
below normal values during this period.
