AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 420 PM EDT SAT MAY 31 2008 .SYNOPSIS... A COLD FRONT WILL MOVE THROUGH THE REGION THIS EVENING...WITH NUMEROUS SHOWERS AND THUNDERSTORMS. BEHIND THIS FRONT...COOLER TEMPERATURES ALONG WITH A FEW SHOWERS IS EXPECTED FOR THE DAY ON SUNDAY. AS WE HEAD INTO THE NEW WORK WEEK...DRY WEATHER ALONG WITH A MODERATING TREND IS EXPECTED. && .NEAR TERM /TONIGHT/... TWO MAIN AREAS OF CONVECTION THIS AFTERNOON THAT WE HAVE OUR EYES ON. FIRST IS LINE BISECTING MY CWA THAT HAS FORMED ALONG A PREFRONTAL TROUGH THAT...EARLIER THIS AFTERNOON INTERACTED WITH A CONVERGENCE ZONE EAST OF LAKE ERIE TO FIRE A LINE OF STORMS. THIS LINE HAS HAD A FEW STORMS NEAR OR JUST ABOVE SEVERE THRESHOLDS AS IT MOVES THROUGH AN ENVIRONMENT OF AROUND 1000J/KG OF CAPE AND PLENTY OF DEEP LAYER SHEAR /ACTUALLY...THIS SHEAR IS HIGHLY EVIDENT IN THE AFTERNOON VIS IMAGERY/. THIS SHEAR...ALONG WITH A LITTLE BIT OF CAPPING EVIDENT FROM AFTERNOON RUC PROFILES...AS WELL AS MORNING ACARS PROFILES...HAS CAPPED MOST OF THE ACTIVITY SO FAR THIS AFTERNOON. THIS SHOULD CHANGE HOWEVER...AS ADVANCING SHORTWAVE BRINGS IN COOLING TEMPS AT MID LEVELS. IN ADDITION...THE IMPLIED UPPER FORCING FOR ASCENT AS THE SHORTWAVE ARRIVES...WHICH IS COLLOCATED WITH THE SURFACE COLD FRONT HAS ALLOWED FOR CONVECTION TO REFIRE ALONG THE EASTERN LAKES...AND THIS WILL BE OUR SECOND ROUND LATER THIS AFTERNOON AND EVENING. ONE LIMITING FACTOR IS THE DRIER AIR FOUND BEHIND THE FIRST BOUNDARY...BUT STILL FEEL WIDESPREAD SHRA/TSRA WILL MOVE THROUGH AND WITH THE THERMODYNAMICS NOT LIKELY TO CHANGE SIGNIFICANTLY BEFORE SUNDOWN...WE COULD CERTAINLY SEE SOME MORE SEVERE HAIL/WIND REPORTS...WITH ROTATING UPDRAFTS NOT LIKELY...BUT STILL NOT OUT OF THE QUESTION. THIS OVERALL EVOLUTION WAS CAPTURED VERY WELL BY YESTERDAY/S NAM BEHIND THE TSRA THIS EVENING...EXPECT A FEW REMAINING SHRA IN THE CYCLONIC FLOW AS THE MAIN VORT LOBE ROTATES SOUTHEAST AND MAKES ITS CLOSEST APPROACH. && .SHORT TERM /SUNDAY THROUGH TUESDAY/... SOMEWHAT OF A RAW DAY ON SUNDAY AS T850 FALLS TO AROUND OR A LITTLE BELOW +5C. WITH TEMPS ALOFT CONTINUING TO COOL...EXPECT QUITE A BIT OF CLOUDINESS...WITH MCLOUDY SKIES LOOKING LIKELY OVER NORTHERN AREAS WITH SCT CLOUDS FURTHER SOUTH. HAVE INCLUDED A CHC FOR SHRA OVER THE NORTHERN THIRD OF THE CWA. HIGHS WILL RANGE FROM 60-65 IN THE NORTH...UP TO AROUND 70 IN THE SOUTH. THE TROUGH PULLS OUT SUNDAY NIGHT WITH CLEARING SKIES AND TEMPS FALLING INTO THE 40S. MONDAY LOOKS LIKE A BETTER DAY THAN SUNDAY AS TEMPS ALOFT QUICKLY MODERATE TO AROUND +10C UNDER NORTHWEST FLOW ALOFT. EXPECT PLENTY OF SUN TO ALLOW US TO REACH THE MID 70S. MONDAY NIGHT A COLD FRONT WASHES OUT AS IT REACHES THE CWA. DON/T EXPECT ANY SHRA WITH THIS FEATURE. IN ADDITION...IT/S POSITION IS IN SOME QUESTION AS THE GFS IS QUITE A BIT QUICKER WITH ITS ARRIVAL THAN THE NAM. EXPECT LOWS TO ONCE AGAIN FALL INTO THE UPPER 40S. TUESDAY...THE FLOW ALOFT FLATTENS...AND ALTHOUGH THE GFS/NAM DIFFER IN THE TIMING FOR THE ARRIVAL OF THE NEXT SHORTWAVE IN THIS FLOW...IT APPEARS THAT THE LIKELIHOOD FOR SHRA AND PERHAPS EVEN TSRA WILL BE ON THE INCREASE. HAVE INCLUDED CHC SHRA AFTERNOON...BUT GIVEN THE LIKELIHOOD THAT CONVECTIVE FEEDBACK IS IMPACTING THE MODELS AT THIS POINT /EVIDENCED BY THEIR EXCESSIVE QPF FIELDS/ CONFIDENCE IS PRETTY LOW ABOUT WHEN ANY PRECIP WILL ARRIVE. TEMPS ALOFT WILL CONTINUE TO BE NEAR +10C AT 850...SO HIGHS REACHING 70-75 GIVEN THE CHANCES FOR RAIN LOOK GOOD. IF THINGS HOLD OFF UNTIL LATER...MID 70S WILL BE MORE LIKELY. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... FOLLOWED HPC GUIDANCE CLOSELY AS FOCUS IS ON SVR WX POTNL THIS AFTN. APPEARS THAT A SYSTEM WILL BRING SHRA/TSRA AROUND MIDWEEK (TUE/WED) THEN RIDGING AND WARMER. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... SCT TSRA THIS AFTN ARE XPCTD TO DIMINISH EARLY THIS EVNG...WITH SCT MVFR/IFR WITH THE STORMS. WILL HAVE TO MONITOR SVR POTNL. MVFR CIGS APPEAR LIKELY LATER TNGT AND EARLY TMRW MRNG...SPCLY AT NRN SITES SYR/RME. WSW WINDS THIS AFTN WITH G25...WNW ARND 10 KTS TNGT THEN INCREASING TO 10-20 TMRW. OUTLOOK....
