area forecast discussion... Updated
national weather service pittsburgh pa
429 pm est Sat feb 23 2019

Synopsis
Widespread rain is expected tonight as low pressure drags a
cold front across the area. Shower chances and very strong wind
gusts are expected behind the front Sunday.

Near term through Sunday night
430pm update... Have lowered pops across the region as area of
showers and sprinkles is decreasing as it drifts northward,
trailing behind the exiting shortwave axis. Expect a break in
the showers until later this evening when the next substantial
wave reaches the region. Temps have been modified as well.

Previous discussion...

while low pressure is currently over the central plains,
rainfall will increase tonight as the warm and cold fronts with
the low move into the region. Models continue to back off on the
qpf forecast, with anywhere from 0.40 to 0.80 inches expected
over the next 36 hours. An isolated lightning strike cannot be
ruled out across westernmost counties, although elevated
instability should be rather limited.

The warm front and cold front should move through in quick
succession tomorrow morning, and that is when the winds will
begin to pick up. There will be a very tight pressure gradient,
and with steep low level lapse rates allowing for strong mixing
of winds above the surface, have issued a high wind warning for
60 mph wind gusts across the entire forecast area. The time for
highest winds should range from late morning through sunset, and
while warning criteria winds are not expected to persist for 24
hours, the warning was issued for the times that at least
advisory level wind gusts are expected. Widespread rain will
move east shortly after sunrise Sunday, and a chance of rain
showers will persist in most locations throughout the day. Not
only will the cold front bring gusty winds, but it will also
bring falling temperatures through the day, so the leftover
showers should change over to snow by sunset. While temperatures
will rise into the low to mid 50s by Sunday morning, they will
fall into the lower 20s by late Sunday night.

Short term Monday through Tuesday
This period should be rather quiet with a ridge of high pressure
building into the region, although an isolated shower will
remain possible north and east of pittsburgh Monday morning.

Temperatures will be about 10 degrees below normal.

Long term Tuesday night through Saturday
A cold front should cross the region Wednesday and Wednesday
night, bringing mostly a chance for snow but also some rain. By
Saturday morning low pressure should be moving across lake erie
and sweeping another cold front through the area. After starting
out below normal, temperatures should rise back to near normal
values by Thursday.

Aviation 22z Saturday through Thursday
Intermittent brief showers and high MVFR expected through the
afternoon as moisture increases ahead of low pressure tracking
across the mississippi valley. CIGS will continue down towards
low MVFR levels during the evening, with steadier rain expected
towards midnight. Low level wind shear will increasing become a
concern this evening and likely remain through the remainder of
the TAF period.

A frontal passage will occur towards the end of the TAF period,
decreasing rain coverage. Wind gusts will pick up dramatically
with a synoptic setup in place that should result in widespread
wind gusts over 40kts... And potentially exceeding 50kts at
times.

Outlook
Ceiling restrictions will ease behind the front. However,
extremely windy conditions are then expected into Sunday night.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
