IMPRESSIVE MESOSCALE FEATURES BY LATE MORNING/EARLY AFTERNOON WITH STRONG MOISTURE CONVERGENCE OVER MUCH OF SOUTHWESTERN PA AND A LINE OF STRONG LOW LEVEL FORCING EXTENDING FROM GARRETT COUNTY NORTHWESTWARD THROUGH PIT.

THE AREA WILL BE UNDER LOTS OF CLOUDS TODAY AND LATEST FORECAST SOUNDINGS ARE SHOWING A LOW-LEVEL INVERSION DEVELOPING EARLY IN THE AFTERNOON. CAPE VALUES ARE RIGHT AROUND 1000J/KG...WITH THE REAL UNSTABLE AIR WELL TO THE SOUTHWEST. THE AFTERNOON SHOULD BE THE BEST TIME FOR HEAVIER CONVECTION.
