AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 316 AM EDT THU MAY 11 2006 .SHORT TERM (TODAY THROUGH TONIGHT)... BASED ON RECENT GFS AND NAM MODEL RUNS, EXPECT THE PASSAGE OF AN OCCLUDED FRONT LATE THIS MORNING INTO EARLY AFTERNOON. THE FRONTAL PASSAGE WILL BE ASSOCIATED WITH A BAND OF SHOWERS AND ISOLATED THUNDERSTORMS MOVING EASTWARD THROUGH THE UPPER OHIO VALLEY. DUE TO THE MIDDAY TIMING OF THESE SHOWERS, HIGH TEMPERATURES WILL BE RESTRICTED FROM GOING MUCH HIGHER THAN CURRENT READINGS. GFS AND NAM MOS VALUES SEEMED REASONABLE FOR LOWS TONIGHT. && .LONG TERM (FRIDAY THROUGH WEDNESDAY)... WITH THE LATEST GFS MODEL RUN CONTINUING THE TREND OF OTHER RECENT MODEL RUNS, EXPECT THE UPPER OHIO VALLEY TO RECEIVE SEVERAL PERIODS OF SHOWERS AND THUNDERSTORMS OVER THE NEXT FEW DAYS, AS A CLOSED UPPER LOW ROTATES SLOWLY THROUGH THE OHIO VALLEY. DUE TO THE GENERALLY CLOUDY CONDITIONS, NIGHTTIME LOWS WILL BE NEAR NORMAL, BUT DAYTIME HIGHS WILL BE COOLER THAN NORMAL, AS INDICATED BY RECENT GFS MOS VALUES. && .AVIATION...
