Synopsis
Above normal temperatures will continue this weekend into early
next week. A low pressure system will impact the region late
tonight into Tuesday night bringing some mixed precipitation to
the area and a moderate to locally heavy rainfall. Some freezing
drizzle is possible for portions of the late tonight into
Monday morning. A colder, seasonable airmass will be ushered
back into the region behind the storm.

Near term until 6 pm this evening
As of 1230 pm est... A cold front has stalled to our north
across northern new york and northern new england and is
expected to remain nearly stationary through the day today.

Stratus clouds will continue to impact the area especially north
and west of the capital district. Warm air advection clouds
will be on the approach from the southwest during the day but
are not expected to reach the local area until after dark. Winds
will be light. High temperatures will vary from the mid 30s to
mid 40s in most areas.

Short term 6 pm this evening through Tuesday night
An expansive southern stream low pressure system over the
plains will begin to impact the local area tonight as it moves
towards the great lakes region. The system becomes vertically
stacked and tracks across the great lakes Monday night into
Tuesday with its cold front sweeping across the local area
Tuesday. The system will deepen over new england Tuesday night
as northern stream energy interacts with it.

Isentropic lift will begin tonight with clouds overspreading the
area and some spotty light precipitation is possible especially
overnight into Monday. The challenge will be the temperature
profile as surface readings fall some this evening and warmer
air moves in aloft setting the stage for freezing precipitation.

Freezing drizzle is the p-type expected, however confidence for
it occurrence is not high enough or widespread enough to issue
a winter weather advisory at this time.

As boundary layer temperatures warms during the day Monday a
changeover to drizzle and eventually rain is expected. However
temperatures will struggle across portions of the southern
adirondacks, upper hudson valley and southern vermont and
portions of the berkshires and should drop a couple few degrees
Monday evening so freezing rain is real threat.

Precipitation is expected to remain light during the day Monday
with steady precipitation developing Monday night especially
late at night as the strengthening low level jet ahead of the
low pressure system moves into the region. Guidance indicates
the 850 mb jet should increase to 50 to 70 knots (2-3 standard
deviations above normal) as it moves across the area mainly to
south and east of the capital district Tuesday morning. This
will push precipitable water values up to around an inch (2-3
standard deviations above normal) and result in a period of
moderate to heavy rainfall Tuesday morning with the bulk of the
qpf falling at this time. This is expected to cause rises on
rivers and streams, which may move and dislodge ice and may
cause flooding near ice jams.

With the passage of the cold front the moderate to heavy rainfall
will come to an end. Rain will continue as the upper trough swings
through. As the low moves off to our east Tuesday night a colder,
seasonable airmass will be ushered in with linger rain changing
to snow with some light accumulations possible.

Temperature forecast is very tough tonight into Tuesday. How
much do readings drop off tonight and how much they rise Monday?
they should remain fairly steady Monday night with temperatures
rising Tuesday ahead of the cold front. Tonight expecting upper
20s to lower 30s with temperatures in the 30s Monday and Monday
night rising into mainly the 40s Tuesday.

Long term Wednesday through Saturday
Medium-range deterministic models and ensemble guidance are in solid
agreement that the long term period will be characterized by a
return to wintry temperatures a bit below normal. It appears another
warm-up will begin by Saturday. On Wednesday, persisting cyclonic
flow and low-level cold air advection with h850 temps around -12c
should support lake effect snow in favored locations of the mohawk
valley and western adirondacks. Low inversion heights expected to
keep accumulations fairly light. Blustery as well Wednesday into
Thursday with the cold advection. Subsident mid-level northwesterly
flow builds in Wednesday night into Friday with accompanying high
pressure at the surface, spelling an end to lake effect activity.

Rather chilly during this timeframe with forecast lows in the single
digits and teens, and highs in the teens and 20s, with winds making
it feel colder through Thursday before the high sets up shop. Return
flow looks to kick in by Saturday providing a boost to temperatures
back above normal values.

Aviation 18z Sunday through Friday
Areas of lowVFR stratus have expanded into kalb kgfl with MVFR
at kpsf with modest moisture advection beneath an inversion.

Expect varying coverage of these stratus throughout the
daylight hours today, with some high clouds as well.

Tonight, low-level moisture advection will increase ahead of a
low pressure system moving across the great plains. This should
allow cloud bases to lower to MVFR and perhaps ifr levels late
in the TAF period. The moisture advection may be accompanied by
patchy drizzle or freezing drizzle as a warm front focuses the
moisture, especially after 06z. Fzdz appears relatively more
likely at kgfl and kpsf where temps are expected to be lower,
but cannot be ruled out at kalb kpou where temps may be around
the freezing mark. Vsby restriction may exist in a combination
of dz and br.

Winds will be light and variable throughout the TAF period.

Outlook...

Monday: moderate operational impact. Chance of ra... Dz.

Monday night: high operational impact. Definite ra.

Tuesday: high operational impact. Definite ra.

Tuesday night: moderate operational impact. Chance of shra... Shsn.

Wednesday: no operational impact. No sig wx.

Wednesday night: no operational impact. No sig wx.

Thursday: no operational impact. No sig wx.

Hydrology
Ongoing flooding due to ice jams will continue to be addressed
with areal flood warnings, as some lingering issues continue due
to existing ice jams which froze in place.

Temperatures will continue to run above normal into early next
week. Tuesday will be the mildest with highs mainly in the 40s
a colder seasonable airmass returns Tuesday night.

A storm will bring a moderate to locally heavy rainfall to the
area. The rain is expected to be light during the day and in the
evening Monday with the bulk of the rain occurring Tuesday
morning. QPF amounts are forecast at this time to range from about
an inch up to possibly 1 1 2 inches. The higher amounts across
expected east of the hudson river valley and across portions of
the central southeastern catskills.

The rain is expected to cause rises on rivers and streams, which
may move and dislodge ice and may cause flooding near ice jams.

Our latest winter spring flood potential outlook (esfaly) was
issued Friday evening.
