High pressure will build in the wake of this evenings cold front and provide a few days of dry weather and seasonable temperature. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Precipitation associated with a prefrontal trough are exiting to the south currently, after producing some flooding in a few spots. Remaining showers along the dewpoint gradient just north of Pittsburgh should remain isolated as that boundary drops across, such that only isolated showers should remain in the southeast counties by dawn. Temperatures/dewpoints are in good shape and made only minor tweaks. && .SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/... A pattern shift is in the works for the latter part of the week, bringing drier weather areawide. In the wake of tonight`s cold front, showers will have all but dwindled by Wednesday morning. Dry high pressure will maintain dry weather through Friday. Temperatures will steadily climb back up to well above average by Thursday and Friday, with higher humidity levels returning by the weekend. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... As quickly as the dry weather arrives this week, it appears it will come to an end heading into the holiday weekend. Moisture gets pumped northward around a potential Gulf tropical system, and shortwave trough moving over the flattened ridge will provide support for several rounds of precipitation. Temperature are expected to be moderated by the clouds and rain, but will remain at least a few degrees above average. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... MVFR/local IFR is expected behind a crossing cold front. The stratus/stratocu cigs should lift with mixing and heating this morning, and eventually scatter out with VFR for the rest of the TAF period under building high pressure. OUTLOOK...
