Area forecast discussion, May 18, 2:27 PM EST, 1 hour 38 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 327 PM EDT MON MAY 18 2015 .SYNOPSIS... A WARM MUGGY AIR MASS WILL COMBINE WITH A NORTH TO SOUTH FRONTAL BOUNDARY TO TRIGGER A FEW SHOWERS AND THUNDERSTORMS ACROSS THE AREA INTO TONIGHT. A COLD FRONT WILL CROSS THE AREA BY EARLY AFTERNOON TUESDAY WITH ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS POSSIBLE. MUCH COOLER WEATHER WILL FOLLOW BEHIND THE FRONT FOR THE MIDDLE AND LATER PART OF THE WEEK. && .NEAR TERM /THROUGH TUESDAY/... LATEST WATER VAPOR IMAGERY SHOWING A DEEP PLUME OF MOISTURE EXTENDING FROM THE GULF STATES AND SOUTHERN ATLANTIC NORTH ACROSS THE EASTERN GREAT LAKES THIS AFTERNOON. SURFACE DEW POINTS IN THE MID TO UPPER 60S AND DEEP LAYER PRECIPITABLE WATER VALUES AROUND 1.75 ARE WELL ABOVE NORMAL FOR MID-MAY. SCATTERED SHOWERS AND THUNDERSTORMS ARE DEVELOPING WITHIN THIS PLUME OF MOISTURE AND THESE SHOWERS ARE EXPECTED TO BECOME INCREASINGLY FOCUSED ALONG A PRONOUNCED SURFACE CONVERGENCE ZONE EXTENDING FROM NEAR SYR TO BGM TO AVP INTO EARLY THIS EVENING. EAST OF THIS BOUNDARY EASTERLY FLOW HAS RESULTED IN TEMPERATURES FALLING INTO THE 60S AT MSV WHILE TO THE WEST TEMPERATURES ARE IN THE 80S WEST OF I-81. LATEST SPC ANALYSIS INDICATES MLCAPE VALUES RANGING FROM 1000-1500 J/KG EAST OF I-81 IN THE WARM MOIST AIR. DEEP LAYER WIND SPEEDS ARE GENERALLY LESS THAN 20 KTS SO EXPECTING MOST STORMS TO BE OF THE PULSE VARIETY... HOWEVER THE LINEAR NATURE OF THE LOW- LEVEL CONVERGENCE COULD RESULT IN SOME POORLY ORGANIZED LINES OF STORMS AS WELL. SEVERAL OF OUR HIGH RESOLUTION CONVECTION-ALLOWING MODELS HAVE BEEN SHOWING COVERAGE OF SHOWERS AND STORMS INCREASING INTO EARLY THIS EVENING. GIVEN THE MOIST ENVIRONMENT WITH WEAK DEEP LAYER WIND FLOW EXPECT THAT THE MAIN CONCERN WITH THESE SHOWERS WILL BE LOCALIZED HEAVY RAIN... ALTHOUGH AN ISOLATED DAMAGING WIND GUST OR LARGE HAIL REPORT CAN'T BE COMPLETELY RULED OUT GIVEN THE MODERATE INSTABILITY NOW OVER THE AREA. SHOWERS WILL DIMINISH LATER THIS EVENING BECOMING ISOLATED OVERNIGHT. LATEST MODEL FORECASTS INDICATE COLD FRONTAL PASSAGE ACROSS CENTRAL NY AND NORTHEAST PA WILL BE LATE MORNING THROUGH EARLY AFTERNOON. INSTABILITY WILL INCREASE LATE TUESDAY MORNING AND THE FRONT MAY TRIGGER A FEW SHOWERS OR STORMS THROUGH MID-AFTERNOON ESPECIALLY FOR AREAS EAST OF I-81. WIND AND SHEAR WILL BE STRONGER THAN TODAY AND MOISTURE WILL BE LESS... THEREFORE THE MAIN THREAT WITH ANY STORMS ON TUESDAY WILL BE GUSTY WINDS AND HAIL. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... QUIET WEATHER IS EXPECTED THROUGH THIS PERIOD WITH MUCH LOWER TEMPERATURES BEHIND THE COLD FRONT. CANADIAN HIGH PRESSURE WILL BUILD ACROSS THE GREAT LAKES TOWARD THE MID-ATLANTIC WEDNESDAY INTO THURSDAY. LOW PRESSURE IS FORECAST TO TRACK FROM THE TENNESSEE VALLEY TOWARD THE CAROLINAS WEDNESDAY NIGHT INTO THURSDAY WITH ASSOCIATED RAIN WELL TO OUR SOUTH. GENERALLY WENT WITH A BLEND OF MAV/MET GUIDANCE FOR TEMPERATURES WEDNESDAY AND THURSDAY WHICH YIELDED UNSEASONABLY COOL HIGHS IN THE MID 50S TO MID 60S ON WEDNESDAY... WARMING A BIT INTO THE 60S ON THURSDAY. LOWS WEDNESDAY NIGHT WILL RANGE FROM THE MID 30S TO MID 40S WITH A TOUCH OF FROST NOT OUT OF THE QUESTION IN NORMALLY COOLER LOCATIONS. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... QUIET PD FOR THE XTNDD. SCNDRY FNT APRCHS THE AREA ON FRI AND MGT GENERATE A FEW SHWRS OVER THE NRN AREAS WITH PEAK HTG. HGTS BLDS AGAIN AS SFC HIPRES BLDS IN FOR THE WEEKEND SO XPCT DRY WEATHER INTO SUNDAY. WITH THE TROFINESS ALOFT IN THE PD...TEMPS WILL BE A BIT COOLER THAN NRML DESPITE THE DAYTIME SUN. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... COMPLEX DBL FNT SYSTEM WILL PUSHES SHWRS AND TRWS INTO THE REGION THIS AFTN AND TNGT. THIS AFTN...HTG AND APRCHG WRM FNT HAS ALREADY GENERATED TSTMS.

CRNT TIMING ON THE FNT WILL GIVE A PASSAGE THRU THE AREA EARLY TUE. LOOKS LIKE A RETURN TO VFR ALL STATIONS IS LIKELY BEFORE THE END OF THE TAF PD. .OUTLOOK...
