Synopsis
High pressure shifts offshore today as a quick moving low pressure
system brings rain and snow to the region. A frontal system and
associated low pressure will impact the area this weekend. High
pressure returns through the middle of next week.

Near term until 6 pm this evening
Forecast generally remains on track, with a transition from snow
to rain now occurring across southern and eastern areas. Little
to no accumulation has been reported. With the upper wave now
moving east of the area, precipitation will likely be more
occasional through the afternoon as the subsidence inversion
strengthens, resulting in a more shallow moisture layer.

Across the interior, weak upslope flow and temperatures
remaining below freezing may result in additional accumulations,
though with the overall decrease in the depth of the moisture,
expect amounts to remain at or below 1-2" total.

Temperatures during the day will rise into the 30s to mid 40s.

Short term 6 pm this evening through 6 pm Friday
Despite mid level drying, lingering low level moisture across
the interior will bring the chance for spotty freezing drizzle
tonight. Not expecting much in the way of ice accumulation, so
have opted for no advisory at this time. Dry conditions are then
expected Friday morning before the next system arrives.

Low temperatures tonight will drop into the upper 20s to upper 30s,
with highs on Friday going above normal, in the mid 40s to
around 50.

Long term Friday night through Wednesday
A more significant rainfall event is in store for the area Friday
night and potentially through the weekend. A frontal boundary will
be in the vicinity Friday night. A weak area of low pressure is
forecast to form along this boundary off the mid-atlantic coast
Saturday morning and track northeast. A period of moderate to
briefly heavy rain is possible late Friday night into Saturday
morning for some portion of the forecast area. The details are still
uncertain at this time, given model spread, so did not add this to
the forecast due to uncertainty of where the axis of heavy rain
would be just yet.

Models further diverge on solutions Saturday night, mainly due to
the position of surface high pressure to our north that may dig far
enough south to cut off any precipitation Saturday night as per the
ecmwf.

As for precipitation type, plain rain is expected for the entire
area from Friday night through Saturday night. Enough cold air could
move into the far northern areas across the lower hudson valley and
southwestern connecticut to change rain to freezing rain or a mix to
freezing rain and sleet Sunday morning. However, this should be
brief as low level temperatures warm up enough to change it back to
rain.

Thereafter, the primary low over the southeast u.S. Will push off
the mid-atlantic coast and will reintroduce rain Sunday and Sunday
night, with the area drying out for Monday. There is the possibility
for some light precipitation to continue for Monday as a shortwave
moves through the northeast, but right now, the thinking is that
precipitation will be limited to north of our area.

High pressure will keep the area dry through the middle of next
week, with temperatures at or below normal for this time of
year.

Aviation 18z Thursday through Tuesday
A combination of MVFR andVFR across the region this afternoon.

Spotty very light precip is possible with rain or drizzle near
the coast and mix further north. No accumulation is expected.

AnyVFR will lower to MVFR and possibly ifr tonight. Patchy
freezing rain or drizzle is possible NW of nyc.

Ne-e winds 10-15 kt at the coast and 5 to 10 kt across the
interior will lighten tonight and veome southeast. Light
southeast wind near 10 kt is ecpected on Friday.
