Area forecast discussion, Sep 1, 10:43 AM EDT, 47 minutes before
Area Forecast Discussion
National Weather Service Pittsburgh PA
1043 AM EDT Wed Sep 1 2021
.SYNOPSIS...
Cool and dry air will flow over the region later today as the remnant
of the tropical system exits.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Latest update was for ewd shifting heavy rainfall and the dropping of
the FFA for part of E.C. OH and the nrn WV Panhandle. The trend will
continue as the upr trough axis and Ida remnant continue to dvlp the
moisture convergence areas east of the ridges. In the meantime, the
primary flood threat is east of the PA wrn border and generally east
of Pittsburgh. Expect an additional 0.5 to 1 inches in those areas.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
Significantly cooler and drier air will filter in behind the remnant
as a rather amplified trough-ridge-trough longwave pattern develops
across the mid-latitudes of North America and strong high pressure
builds across the Great Lakes. This pattern will provide a dry and
comfortable end to the week.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
The longwave pattern is projected to dampen, with the Pittsburgh
forecast area placed in general WNW flow aloft. Expect dry and cool
weather with exception for a shortwave passage forecast for Sunday
afternoon.
&&
.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
Rain associated with the tropical remnant Ida wl maintain
deteriorated MVFR to IFR conditions until upr trough passage heralds
improvement later this aftn and into the eve.
A sufficient pres gradient should result in increasing NE wind Wed.
Wind should diminish and back to the NW Wed night as the low exits.
.Outlook...
The next genl restriction chc wl come with the crossing of a late
Saturday disturbance.
