Area Forecast Discussion
National Weather Service Pittsburgh PA
501 AM EST Thu Mar 4 2021

.SYNOPSIS...
Other than slight precipitation chances north and east of Pittsburgh
early this morning, building high pressure should maintain dry
weather through the weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Made some adjustments to sky cover today based on latest satellite
and near term model data. Previous...Areas of stratocu are expected
to overspread the area this morning, and continue this afternoon, in
cold NW flow behind an exiting cold front. Isolated snow showers are
possible N of I 80 and in the ridges, though a shallow moisture layer
under lowering subsidence inversions should limit this activity.
High temperatures are expected to be around 5 degrees below average.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
An upper low is progged to persist across Eastern Canada through the
weekend. Sfc high pressure building under the resulting NW flow aloft
should maintain dry weather through the period, though a couple of
weak troughs rotating around the low could result in some periodic
increase in clouds across the Lower Great Lakes/Upper Ohio Valley
region.

Temperatures are expected to average around 5 degrees below
seasonable levels through the period.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The upper low is expected to move east Sunday. Riding should then
build across the Central and Eastern CONUS through mid week, ahead of
a Western CONUS trough. This should result in continued dry weather,
but with a warming trend.

&&

.AVIATION /10Z THURSDAY THROUGH MONDAY/...
High pressure in place with northwest flow will bring some
stratocumulus over the area by 12Z. This will bring some MVFR and IFR
cigs across the area. It is possible that a few snow showers may
develop but mainly in the north near FKL and DUJ. Any local snow
shower may reduce vis to MVFR and even IFR. Winds will quickly ramp
up by dawn and continue into the day with northwest winds gusting up
to 20 knots at times, with some locally higher winds.

.Outlook...
Ceiling restrictions are possible with a late Friday cdfnt.

&&

.PBZ WATCHES/WARNINGS/ADVISORIES...
PA...None.
OH...None.
WV...None.
