AN APPROACHING COLD FRONT WILL INTERACT WITH VERY MOIST AIR ACROSS THE REGION TO PRODUCE NUMEROUS SHOWERS AND THUNDERSTORMS THROUGH MUCH OF THE DAY TUESDAY.

MOST UNSTABLE AIR WILL RESIDE ACROSS MAINLY THE SWRN HALF OF THE STATE THROUGH THIS EVENING. MCV NEAR KERI WILL LIFT NE ALONG I-90 LATE TODAY...SUPPORTING AN AREA OF WIDESPREAD/TRAINING TSRA. EXPANDED THE FLASH FLOOD WATCH TO INCLUDE THE WESTERN AND NW MTNS...IN ADDITION TO THE EARLIER ISSUANCE FOR PORTIONS OF SCENT PENN.

THE NW HALF OF PENN WILL BE MOST AT RISK FOR SHRA/TSRA BEFORE SUNRISE...AS THE SFC CFRONT CROSSES THE LOWER GREAT LAKES. THE FRONT SHOULD PUSH THRU FROM NW TO SE DURING THE DAYLIGHT HRS TUES...WITH THE MEAN LLVL/WESTERLY FLOW WEAKENING AND BECOMING PARALLEL TO THE BOUNDARY AS IT SAGS TWD THE MASON DIXON LINE. DON'T EXPECT MUCH RELIEF IN THE HUMIDITY DEPT IN THE WAKE OF THE CFROPA LATER TUESDAY/TUESDAY EVENING...AS SFC DEWPOINTS STAY IN THE 60S /MID TO UPPER 60S ACROSS THE SOUTHERN THIRD OF THE STATE/.

FOR THE WEEKEND...TIMING OF INDIVIDUAL SFC/UPPER VORTICITY FEATURES AND ASSOCIATED LOW LEVEL FRONTAL BOUNDARIES WILL BE DIFFICULT...SO MANY PERIODS CONTINUE TO CONTAIN THE CHANCE FOR A FEW SHRA/TSRA...WITH HIGHEST CHANCES BEING SUN/SUN NIGHT.
