AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 157 PM EDT SAT JUN 28 2008 .SYNOPSIS... THUNDERSTORMS CAN BE SEVERE THROUGH EARLY TONIGHT WITH DAMAGING WIND LARGE HAIL AND HEAVY RAIN. THERE CAN BE ANOTHER ROUND OF THUNDERSTORMS SUNDAY AS A CANADIAN COLD FRONT CROSSES THE UPPER OHIO VALLEY. IN THE FRONTS WAKE WILL COME A COLD UPPER LEVEL LOW PRESSURE CENTER THAT WILL MAINTAIN A CHANCE OF SHOWERS AND THUNDERSTORMS INTO TUESDAY EVEN AS TEMPERATURES COOL DOWN AND HUMIDITIES BECOME COMFORTABLE. && .NEAR TERM /THROUGH SUNDAY/... CONCUR WITH SPC THAT THUNDERSTORMS CAN BE SEVERE INTO EARLY TONIGHT. THE HUMID AND NOW HEATED SURFACE LAYER WILL PROMOTE MODERATE INSTABILITY WITH CAPE VALUES OVER 1500 J/KG. WINDS ARE INCREASING AT ALL LEVELS WHICH WILL INCREASE VERTICAL WIND SHEAR SUFFICIENTLY/ THAT IS 0-6KM BULK SHEAR VALUES OVER 30 KTS/ TO PROMOTE SEVERE THUNDERSTORMS THAT CAN ORGANIZE INTO BOWING LINES. THIS SCENARIO FAVORS DAMAGING WIND AS THE PRIME HAZARD WITH LARGE HAIL SECONDARY. ALTHOUGH THE STORMS CAN GENERATE RAINFALL RATES OVER 1.5 INCHES AN HOUR...IN GENERAL THE STORMS SHOULD MOVE FAST ENOUGH AND NOT TRAIN TO CAUSE THIS MUCH RAINFALL FOR ANY ONE SPOT. HOWEVER SOIL CONDITIONS ARE SUCH THAT IF ANY LOCATION GETTING 1.5 INCHES IN LESS THAN 3 HOURS CAN SEE FLOODING DEVELOP WHERE DRAINAGE IS POOR. JUDGING FROM RECENT SREF MODEL RUNS...THE STORMS WILL WEAKEN BY MIDNIGHT ...WITH SOME CLEARING LATE NIGHT. NEXT UPPER SHORT WAVE TROUGH APPROACHES SUNDAY MORNING JUST AHEAD OF COLD FRONT...WITH THE POTENTIAL FOR STRONG STORMS STARTING AROUND DAWN. THE COLD FRONT WILL CROSS THE REGION SUNDAY AFTERNOON ACTING AS A CATALYST FOR MORE THUNDERSTORM GENESIS. TEMPERATURES WILL BE SOMEWHAT FLAT SUNDAY...WITH LITTLE DIURNAL CURVE...GIVEN FRONTAL PASSAGE. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... BLEND OF RECENT SREF AND GEFS /GFS ENSEMBLE/ MODEL RUNS SHOW THE ENSUING COLD UPPER LEVEL LOW CENTER PROMOTING SUFFICIENTLY UNSTABLE CONDITIONS INTO LATE TUESDAY TO INDUCE A CHANCE OF SHOWERS AND THUNDERSTORMS. FORECASTED TEMPERATURES TO BE SEVERAL DEGREES COLDER THAN NORMAL THIS PERIOD AS INDICATED BY BLEND OF VALUES FROM RECENT SREF MODELS...GFS MOS AND HPC GUIDANCE. && .LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/... LEND OF RECENT SREF AND GEFS /GFS ENSEMBLE/ MODEL RUNS SUGGEST A DRY INTERLUDE WEDNESDAY INTO THURSDAY AS THE UPPER LOW MIGRATES TO HUDSONS BAY. HOWEVER A FAIRLY ROBUST SHORT WAVE TROUGH ALOFT WILL DEVELOP A COLD FRONT ACROSS THE GREAT LAKES THURSDAY THAT COULD MOVE THROUGH THE UPPER OHIO VALLEY FRIDAY INTO SATURDAY. THIS SCENARIO WILL PROMOTE A CHANCE OF THUNDERSTORMS FOR THE JULY 4TH HOLIDAY PERIOD. FORECASTED TEMPERATURES WEDNESDAY INTO THURSDAY INDICATE A REBOUND TO NEAR NORMAL TEMPERATURES BUT THE PROSPECTS OF A SECOND FRONTAL PASSAGE WITH PRECIPITATION SUGGEST COOLER THAN NORMAL TEMPERATURES BY THE WEEKEND. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... STRONG TO SEVERE STORMS ARE POSSIBLE THIS AFTERNOON AND EVENING IN AN INCREASINGLY UNSTABLE AIRMASS. ANOTHER WAVE WILL CROSS THE REGION SUNDAY MORNING WITH A WAVE OF STORMS POSSIBLE. A COLD FRONT WILL CROSS SUNDAY AFTERNOON...WITH MORE STORMS. WHILE CONDITIONS WILL PREVAIL AT VFR THROUGH SUNDAY...IFR CONDITIONS CAN OCCUR IN AND NEAR STORMS. WIND GUSTS CAN GO OVER 50 KTS AND THERE CAN BE LARGE HAIL. BLEND OF RECENT SREF AND GEFS /GFS ENSEMBLE/ MODEL RUNS SHOW SOME SCATTERED SHOWERS AND THUNDERSTORMS POSSIBLE MONDAY AND TUESDAY AS WELL...WITH COLD MID LEVEL UPPER LOW HOLDING. A FEW PERIODS OF IFR WILL BE POSSIBLE DURING THIS TIME PERIOD. MORE SETTLED WEATHER IS EXPECTED FOR WEDNESDAY...BEFORE ANOTHER COLD FRONT AFFECTS THE UPPER OHIO VALLEY WITH THUNDERSTORMS AND SHORT-LIVED BOUTS OF IFR LATE THURSDAY INTO SATURDAY. && .PBZ WATCHES/WARNINGS/ADVISORIES...
