Area forecast discussion, Mar 22, 3:26 PM EDT, 2 hours 27 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 326 PM EDT MON MAR 22 2010 .SYNOPSIS... LOW PRESSURE MOVING ACROSS THE DISTRICT WILL BRING A CONTINUED CHANCE FOR SHOWERS THROUGH TUESDAY NIGHT...BEFORE CONDITIONS DRY OUT FOR WEDNESDAY AND THURSDAY. && .NEAR TERM /THROUGH TUESDAY/... LOW PRESSURE CURRENTLY OVER NORTHERN WEST VIRGINIA WILL CONTINUE TO MEANDER TO THE NORTHEAST. DRIER AIR WRAPPING INTO THE SYSTEM HAS ALLOWED FOR SOME PARTIAL CLEARING FROM THE SOUTH. WITH DEWPOINTS IN THE 50S TO THE NORTH OF THE OCCLUDED FRONT...HIGHER INSTABILITY VALUES HAVE MOVED INTO THE AIR. ONE OR TWO ISOLATED THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON...AND EXPECT THAT SOME SCATTERED COVERAGE WILL CONTINUE INTO THE EARLY EVENING HOURS. SPC STILL HAS MOST OF THE FORECAST AREA IN THE 5% THREAT AREA FOR SEVERE HAIL (CRITERIA FOR WHICH HAS INCREASED TO QUARTER SIZE HAIL). ANY THUNDERSTORMS SHOULD QUICKLY DIMINISH AFTER SUNSET. AS THE LOW MOVES TO THE NORTHEAST...EXPECT THAT WRAPAROUND MOISTURE WILL EVENTUALLY COME BACK THROUGH THE FORECAST AREA. THIS PRECIPITATION SHOULD DIMINISH ON TUESDAY...WITH COOLER TEMPERATURES IN THE FORECAST. HIGHS ARE ONLY EXPECTED TO REACH THE 40S ON TUESDAY...A 20-25 DEGREE DROP. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... LOW PRESSURE IS EXPECTED TO BE OVER WESTERN CONNECTICUT BY TUESDAY NIGHT...WITH PRECIPITATION PRIMARILY CONTAINED ALONG THE RIDGES DURING THAT TIME PERIOD. SOME WET SNOWFLAKES COULD MIX IN WITH RAIN NORTH OF I-80 AS WELL. HIGH PRESSURE WILL MOVE IN FROM THE CENTRAL PLAINS ON WEDNESDAY...BRINGING DRIER AIR INTO THE REGION BEFORE LOW PRESSURE FOLLOWS FROM THE EAST. AT THIS POINT...EXPECT THAT THE WARM FRONT WITH THE SURFACE LOW WILL REMAIN FAR ENOUGH WEST THAT CONDITIONS SHOULD REMAIN DRY FOR THURSDAY. HIGH PRESSURE WILL BRING TEMPERATURES BACK TO SLIGHTLY ABOVE NORMAL VALUES. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... BLEND OF RECENT GEFS AND ECMWF MODEL OUTPUT SHOW A COLD CANADIAN LOW PRESSURE SYSTEM PUSHING A COLD FRONT THROUGH THE UPPER OHIO VALLEY THURSDAY NIGHT OR DAYTIME FRIDAY. THE MODELS LIKEWISE SUGGEST THERE CAN BE A PHASING OF THIS FRONTAL LIFT WITH MOISTURE AND LIFT ASSOCIATED WITH A PACIFIC LOW PRESSURE SYSTEM THAT WILL COME THROUGH SOUTHERN CALIFORNIA AND MOVE THROUGH THE TENNESSEE VALLEY THURSDAY AND CAROLINAS FRIDAY. HOWEVER HPC GUIDANCE INDICATES LESS UNCERTAINTY OF THIS PHASING AND ITS EFFECT ON THE UPPER OHIO VALLEY. SO FOR NOW HAVE FORECASTED A CHANCE OF SHOWERS THURSDAY NIGHT AND FRIDAY FOR ONLY AREAS SOUTH OF I-70 CORRIDOR. ENSUING CANADIAN HIGH PRESSURE WILL PROVIDE THE UPPER OHIO VALLEY WITH CHILLY TEMPERATURES FOR THE REST OF THE PERIOD AS INDICATED BY HPC GUIDANCE AND GFS MOS VALUES. SATURDAY AND LIKELY DAYTIME SUNDAY WILL BE DRY AS THE NEXT PACIFIC LOW PRESSURE SYSTEM COMING THROUGH WASHINGTON STATE MAY NOT AFFECT THE UPPER OHIO VALLEY UNTIL DAYTIME MONDAY. DUE TO THE CHILLY TEMPERATURES...PRECIPITATION TYPE COULD INCLUDE A MIX WITH SNOW THIS PERIOD. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... JUDGING FROM RECENT SURFACE AND RADAR DATA COUPLED WITH RUC MODEL SIMULATED RADAR OUTPUT...EXPECT A BAND OF MVFR RAIN SHOWERS AND POSSIBLY SCATTERED THUNDERSTORMS TO DEVELOP AND MOVE NORTHWESTWARD THROUGH THE UPPER OHIO VALLEY LATE THIS AFTERNOON. SPC HAS INDICATED THERE IS A SLIGHT CHANCE OF HAIL AND GUSTY WINDS WITH THE THUNDERSTORMS. THE I-80 CORRIDOR WILL REMAIN MVFR AND MAY BE TOO STABLE TO BE AFFECTED BY THE CONVECTIVE BAND. RECENT SREF MODEL OUTPUT AND NAM MODEL PROFILES SHOW THAT AS THE LOW PRESSURE SYSTEM CONTINUES MOVING NORTHEASTWARD THROUGH NORTH CENTRAL PENNSYLVANIA AND THEN NEW ENGLAND...POST SYSTEM WRAP-AROUND MVFR SHOWERS WILL CONTINUE ACROSS THE UPPER OHIO VALLEY INTO DAYTIME TUESDAY. THERE CAN BE A PERIOD OF IFR CONDITIONS TONIGHT INTO TUESDAY MORNING DUE TO SURFACE LAYER SATURATION. SURFACE WINDS WILL BE GENERALLY FROM THE SOUTHEAST 8-13 KTS THIS AFTERNOON WITH GUSTS 20-25 KTS...AND THEN BECOME SOUTHWESTERLY AT 6-10 KTS TONIGHT AND WESTERLY TUESDAY AT 10-15 KTS. MIDWEST HIGH PRESSURE WILL BUILD OVER THE UPPER OHIO VALLEY WEDNESDAY INTO THURSDAY AND RESTORE VFR CONDITIONS. A CANADIAN COLD FRONTAL PASSAGE MAY CAUSE MVFR CONDITIONS THURSDAY NIGHT INTO FRIDAY WITH ISOLATED MIXED SHOWERS. ENSUING CANADIAN HIGH PRESSURE SHOULD RESTORE VFR CONDITIONS FOR THE WEEKEND. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. &&
