Area Forecast Discussion

635 AM EST Sun Feb 26 2017

.SYNOPSIS...
A ridge of high pressure over the Mississippi Valley will build
east across Pennsylvania today, then off the east coast early
next week. Low pressure will track north of the area during the
middle of the week, with a trailing cold front pushing through
Pennsylvania late Wednesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Minor update to increase cloud cover over southern half of CWA. High
pressure building into region this morning. Pressure gradient
will weaken and gusty winds will diminish, along with any snow
showers. Temperatures will feel quite cold given how warm its
been this month but will be close to average.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
High pressure shifts off the Mid Atlantic coast Sunday night
with clouds increase ahead of shortwave tracking through the Mid
MS/OH Valley. Model blend keeps pcpn well to the SW of the area
through daybreak Monday with low pops Monday as well. Temperatures
will begin to moderate with highs once again above average on
Monday.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Elongated low developing over the central U.S. on Tue will edge
a warm frontal boundary toward the region, bringing chance for
light precipitation and ushering in another round of warmer than
normal temperatures (though not as high as the past few days).
By Wed, upper wave catches up to the low, bringing a more
significant rainfall, followed by a cold frontal passage.

Colder and very breezy conditions then in store for late week in
NW flow, along with sct lake effect snow showers in the NW Mtns.

Cooler air lingers into the weekend as upper flow remains from
the NW.

Yet another weather system slides through the Great Lakes over
the weekend, with center of low likely remaining to our north.
The greatest shower chances are over the NW half of the CWA.

&&

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
Still some snow showers and flurries as of 6 AM.

Will adjust 12Z TAFS for current activity.

Gusty winds across the region today. Some snow showers and
flurries across the region until early afternoon, when winds
shift more to the west and southwest. MDT and LNS not likely
to see flurries, but still have some clouds early.

All sites should be VFR by early to mid afternoon, as winds
shift, as noted above.

Some rain showers Tuesday into Wednesday, as winds shift to the
south, and warm advection sets in. Potential for strong wind
gust later Wednesday into Thursday with a fast moving cold
front.

Outlook...

Mon...VFR.

Tue-Wed...Rain showers/Sub-VFR reductions likely.

Thu...Strong FROPA early with gusty winds. Sub-VFR likely west.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
None.
