Area forecast discussion, Jun 14, 6:11 PM EDT, 2 hours 19 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Pittsburgh PA
611 PM EDT Mon Jun 14 2021

.SYNOPSIS...
Thunderstorms will end over southern portions of the area this
evening as a cold front exits the region Another crossing
disturbance will maintain lower shower and thunderstorm chances
Tuesday. High pressure will then provide dry and cooler weather for
Wednesday and Thursday.

&&

.NEAR TERM /THROUGH TUESDAY/...
Line of storms continues to move southeast, ahead of a southward
moving cold front. The activity has been maintained by numerous
outflow boundaries that continue to spread away from dying
convection. The first severe watch has ended and a second is now in
effect for the southern border, in WV, until 9pm.

A generally quiet overnight is then expected with the loss of
instability and the passage of the front.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
Another shortwave rotating through the main northeast CONUS trough
will fire off a few showers and thunderstorms on Tuesday. Coverage
will be more sporadic with less upper support, and severe weather is
not expected as instability and shear will be more subdued.

Activity will end Tuesday evening as the shortwave departs. Surface
high pressure digging into the Great Lakes will then spread its
influence over our area, bringing dry and cooler weather through
Wednesday night. Low temperatures in the 40s will make a return
appearance.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
Dry weather will continue through at least Thursday night as the high
remains in control. The next shortwave trough is then expected to
advance from the Upper Midwest, with shower and thunderstorm chances
returning late Friday and into Saturday as it approaches and crosses
the region. Low, shortwave-dependent shower chances will then
continue into Monday, with seasonable temperatures overall.

&&

.AVIATION /22Z MONDAY THROUGH SATURDAY/...
General VFR for early portions of the forecast period. The exception
would be at MGW which will see the risk for a thunderstorm very early
in the forecast period. Expect IFR to MVFR fog to develop at most
ports later tonight, especially those which saw rain.

Fog will burn off quickly Tuesday morning, with return to VFR
expected at all ports. Wind gusts will pick up by late morning with
northwest winds of 15 to 25 mph anticipated.

.Outlook...
Periodic rain chances from passing shortwaves within a developing
eastern U.S. trough may also create intermittent restrictions through
Tuesday. VFR under high pressure is expected mid-week.

&&

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