.DISCUSSION...
KEY MESSAGE 1...

A nor`easter is currently centered across southern New Jersey
and will continue to sit and spin near the mid-Atlantic coast
though tonight. This storm has also begun its weakening stage
with its central pressure rising to near 1000 hPa based on the
latest RAP analysis. A band of rain continues to slowly lift
northward and westward into areas north of I-90 with a well
pronounced dry slot bringing a brief dry period to areas mainly
south of I-90. This dry slot will get cut off later this
afternoon into tonight as another moisture plume and band of
rain rotates around the primary low and reaches the area
tonight and continues through much of tomorrow. So, expect
periods of rain to continue through Monday for much of the
region. The low will begin to track northeastward and out to
sea by Monday night with precipitation ending across the region.
Additional rainfall amounts of 0.50 to 1.00 inches are expected
for many areas through tomorrow with up to 2 inches in the
eastern Catskills. With the continued long duration of this
event plus some dry periods and hourly rainfall rates mainly
0.25 inches or less, no hydrological issues are expected.

With the weakening of the storm itself, the strongest winds from
this storm have ended. The wind advisory that was in effect for
portions of the mid-Hudson Valley, southern Taconics, Litchfield
County and Berkshire County was allowed to expire at noon. Wind
gusts up to around 30 mph are expected through this afternoon
before diminishing further tonight and through tomorrow. By
tomorrow, wind gusts will only be around 20 mph.

The persistent clouds and occasional rain will keep high
temperatures below normal in the mid-50s to lower 60s through
tomorrow. Partial clearing by Monday night along with light to
calm winds should allow for some fog formation.

KEY MESSAGE 2...

Upper level ridging and surface high pressure build across the
region on Tuesday and remains into Thursday with a period of
drier weather. Temperatures will slowly rebound back to near
normal levels on Wednesday and above normal levels on Thursday.
The next chance for rain showers looks to be on Friday as a cold
front approaches from the west.
