AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 249 PM EDT THU JUN 26 2008 .SYNOPSIS... A STALLED WARM FRONT WILL KEEP WARM AND HUMID CONDITIONS ACROSS THE UPPER OHIO VALLEY INTO THE WEEKEND. SCATTERED THUNDERSTORMS CAN BE EXPECTED TONIGHT AND FRIDAY. A CANADIAN COLD FRONT WILL BRING MORE WIDESPREAD THUNDERSTORMS SATURDAY INTO SUNDAY FOLLOWED BY MORE COMFORTABLE CONDITIONS STARTING MONDAY. && .NEAR TERM /THROUGH FRIDAY/... SCATTERED STORMS ARE A POSSIBILITY FOR THIS AFTERNOON AND EVENING...RESULTING FROM DIFFERENTIAL SOLAR HEATING ALONG THE CLOUD BOUNDARIES DEPICTED IN RECENT SATELLITE DATA. WITH THE RECENT SREF MODEL RUN SHOWING A UPPER LEVEL SHORT WAVE TROUGH MOVING EASTWARD THROUGH THE UPPER OHIO VALLEY TONIGHT...A FEW STORMS COULD BE TRIGGERED LATE. THE AIRMASS WILL REMAIN UNSTABLE INTO FRIDAY...WITH ADDITIONAL WEAK WAVES ALOFT HELPING TO INITIATE CONVECTION. THERE IS A SLIGHT RISK OF STORMS REACHING SEVERE POTENTIAL AS INDICATED BY SPC CONVECTIVE OUTLOOK. INSTABILITY CAN BE LARGE DUE TO THE HUMID SURFACE LAYER BUT VERTICAL WIND SHEAR APPEARS MARGINAL. TEMPERATURES WILL BE AT OR ABOVE NORMAL FOR THE PERIOD AS INDICATED BY RECENT SREF AND NAM AND GFS MOS. && .SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/... JUDGING FROM BLEND OF RECENT SREF MODEL RUNS...EXPECT THUNDERSTORM POTENTIAL TO SHOW LITTLE CHANGE LATE FRIDAY INTO EARLY SATURDAY...THAT IS SCATTERED IN COVERAGE WITH POTENTIAL TO BRIEFLY PULSE INTO THE SEVERE RANGE. HOWEVER AS THE CANADIAN COLD FRONT AND ASSOCIATED COLD UPPER LEVEL LOW CENTER ADVANCE THROUGH THE GREAT LAKES SATURDAY...THE THUNDERSTORMS WILL BECOME MORE NUMEROUS AND POTENTIALLY ORGANIZED INTO LINES ACROSS THE UPPER OHIO VALLEY. THIS IS DUE TO THE INCREASED WINDS ALOFT AND HENCE INCREASED VERTICAL WIND SHEAR. THE INSTABILITY WILL REMAIN LARGE DUE TO THE HUMID SURFACE LAYER. THE PRIME SEVERE THREAT SHOULD BE DAMAGING WIND...WHILE LARGE HAIL AND HEAVY RAIN POSE SECONDARY THREATS. THE SPECIFIC TIME OF DAY SUCH A PREFRONTAL LINE OF THUNDERSTORMS MOVES THROUGH THE UPPER OHIO VALLEY WILL EFFECT THE SEVERITY...WITH LATE AFTERNOON AND EARLY EVENING THE MOST HAZARDOUS TIME FRAME. SEVERAL SREF MODEL MEMBERS INDICATE THIS POSSIBLE SCENARIO. FORECASTED TEMPERATURES WERE BASED ON A CONSENSUS OF SREF VALUES AND NAM AND GFS MOS. && .LONG TERM /SUNDAY THROUGH THURSDAY/... BLEND OF RECENT GEFS/GFS ENSEMBLE/ AND ECMWF MODEL RUNS SHOW THE COLD UPPER LOW SLOWING AS IT MOVES THROUGH THE GREAT LAKES AND NORTHEASTERN U.S. SUNDAY INTO WEDNESDAY. THIS WILL MAINTAIN INSTABILITY SHOWERS AND THUNDERSTORMS ACROSS THE UPPER OHIO VALLEY INTO MONDAY AS THE COOL DOWN ALOFT WILL BE LARGER THAN THE COOL DOWN IN THE SURFACE LAYER. EXPECT THAT BY AROUND TUESDAY...THE SURFACE LAYER WILL SUFFICIENTLY DRIED AND THE COLD TEMPERATURES ALOFT SUFFICIENTLY MODERATED TO DISSIPATE THE PROSPECTS OF SHOWER DEVELOPMENT. BASED ON A CONSENSUS OF HPC GUIDANCE AND GFS MOS...FORECASTED HIGH TEMPERATURES MONDAY AND TUESDAY TO BE NEARLY 10 DEGREES COOLER THAN NORMAL BEFORE MODERATING WEDNESDAY AND THURSDAY. SURFACE DEW POINTS WILL LIKEWISE BE IN THE COMFORTABLE RANGE. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... GENERALLY VFR CONDITIONS CAN BE EXPECTED THROUGH FRIDAY...WITH CONDITIONS LOWERING TO MVFR AT TIMES THIS EVENING IN SCATTERED STORMS. SOME MVFR VISIBILITIES IN FOG ARE POSSIBLE OVERNIGHT TOWARD DAWN. A PERIOD OF VERY UNSETTLED WEATHER IS EXPECTED FOR FRIDAY THROUGH TUESDAY...AS A SERIES OF FRONTS AND UPPER WAVES PASS EASTWARD ACROSS THE REGION. WHILE CONDITIONS WILL PREVAIL DURING THE PERIOD AT VFR...IFR WILL BE POSSIBLE AT TIMES IN STORMS. THERE IS ALSO SOME SEVERE POTENTIAL...MAINLY ISOLATED INTO FRIDAY BUT POTENTIALLY MORE WIDESPREAD SATURDAY. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. &&
