NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jul 7, 2:04 PM EST, 57 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 304 PM EDT MON JUL 7 2014 .SYNOPSIS... A SERIES OF FRONTAL BOUNDARIES WILL PASS THROUGH THE AREA THROUGH TUESDAY. THESE FEATURES WILL BRING THUNDERSTORMS PRIMARILY DURING THE AFTERNOON AND EVENING HOURS...SOME OF WHICH COULD BE SEVERE WITH DAMAGING WINDS AND LOCALLY HEAVY RAINFALL. COOLER AND DRIER WEATHER IS LIKELY ON WEDNESDAY AFTER A COLD FRONT MOVES THROUGH THE REGION. && .NEAR TERM /THROUGH TUESDAY/... 300 PM UPDATE... SEVERE THUNDERSTORM WATCH NUMBER 397 HAS NOW BEEN ISSUED FOR THE ENTIRE AREA THROUGH 10 PM. PRIMARY THREAT IS FOR SCATTERED DAMAGING WINDS OF 60-70 MPH WITH SEVERE CELLS...BUT A LARGE HAIL AND EVEN AN ISOLATED TORNADO CANNOT BE RULED OUT. ELEVATED INSTABILITY THUS FAR HAD BEEN REALIZED AS BANDS OF SHOWERS/EMBEDDED THUNDER SWEEPING ACROSS PORTIONS OF CENTRAL NY. EXTENSIVE CLOUDS FROM THESE FEATURES LIMITED INSTABILITY...AND SKEWED ZONE OF MOST LIKELY ACTIVITY FARTHER SOUTHEAST COMPARED TO PREVIOUS FORECASTS...MORE TOWARDS TWIN TIERS AND ESPECIALLY POINTS SOUTH WHERE DIURNAL WARMING IS MORE ABLE TO OCCUR. THAT BEING SAID...STRONGLY SHEARED ENVIRONMENT CONTINUES TO SUGGEST SEVERE WEATHER POTENTIAL FOR THE NEW ACTIVITY THAT DOES MANAGE TO DEVELOP...BUT CAPE LOOKS LIKELY TO BE LIMITED TO LESS THAN 1000 J/KG IN THE NORTHERN ZONES. OUR LOCAL SEVERE WEATHER ANALOG TOOL...COMPARING CONDITIONS TO PAST EVENTS...NOW RETURNS JUST A HANDFUL OF SPORADIC DAMAGING WIND EVENTS WHEN LIMITING CAPE TO LESS THAN 1000 J/KG...YET MORE SIGNIFICANT EVENTS IF PUTTING CAPE ABOVE 1000 J/KG...WHICH IS REASONABLE FOR WHAT MAY BE REALIZED TWIN TIERS SOUTHWARD. GIVEN THE ENVIRONMENT...ESPECIALLY IN TERMS OF 0-1KM HELICITY IN THE 100-150 M2/S2 RANGE...ANY NEWLY DEVELOPING CELL WILL HAVE TO BE WATCHED CLOSELY. COVERAGE OF SUCH CELLS WILL PROBABLY BE MORE LIMITED IN THE NORTHWESTERN ZONES COMPARED TO PRIOR THINKING...BUT CENTRAL TO SOUTHEAST ZONES WILL STILL HAVE A GOOD AMOUNT OF COVERAGE. PRECIPITABLE WATER POOLING TO NEARLY AN INCH-AND-THREE-QUARTERS CONTINUES TO SUPPORT LOCALLY HEAVY RAIN POTENTIAL...AND MESO-BETA ELEMENT VECTORS SUGGEST SOME POSSIBILITY OF BACK-BUILDING AS ORIENTATION OF CONVECTIVE LINES BECOMES NEARLY PARALLEL TO THE INCREASING...AND MOIST...SOUTHWEST LOW LEVEL JET. EVOLUTION WILL MONITORED CLOSELY...BUT ACTUAL FLASH FLOOD PROBLEMS WHILE POSSIBLE ALSO APPEARS LIKE THEY WILL BE VERY ISOLATED IN NATURE. WHAT FALLS THIS AFTERNOON-EVENING HOWEVER WILL PLAY A ROLE INTO SENSITIVITY TO ADDITIONAL RAINFALL ON TUESDAY. SPEAKING OF TUESDAY...A NEW ROUND OF THUNDERSTORMS IS EXPECTED WITH A DEEPER SHEAR ENVIRONMENT ALONG WITH BETTER FORCING COMPARED TO TODAY AS COLD FRONT APPROACHES. WHOLE AREA IS ALREADY OUTLOOKED AS SLIGHT RISK BY SPC DAY TWO OUTLOOK. IF INSTABILITY CAN BE REALIZED...IT IS POSSIBLE THAT OUR RISK COULD BE UPGRADED...BECAUSE AMOUNT OF SHEAR AND STRONGER FORCING. THE TIMING SHOULD BE LATER COMPARED TO ACTIVITY TODAY...MAINLY LATE AFTERNOON THROUGH EVENING. FLASH FLOOD POTENTIAL TUESDAY MAY ALSO BECOME MORE A CONCERN BECAUSE OF SOILS BEING PRIMED BY INITIAL RAINFALL THIS AFTERNOON-EVENING...AND WITH VERY MOIST PRECIPITABLE WATER VALUES...APPROACHING 2 INCHES. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... TUESDAY EVENING INTO THE OVERNIGHT A STRG UPPER LEVEL WAVE AND ASSCTD FRNT WILL PUSH THRU NY AND PA. ANY THUNDERSTORM ACVTY OR MCS COMPLEXES WILL BE MOVING EAST ACRS THE REGION OR BE E OF THE REGION DURING THIS TIME FRAME. HAVE POPS IN THE GRIDS THAT GRADUALLY TAPER DOWN. BY 09Z-12Z WED...UPPER LEVEL PV LOVE PUSHES THRU WITH RESIDUAL MOISTURE LEFT IN THE LL/S...HENCE I STILL HAVE SLGHT CHC POPS LINGERING ERLY WED AM. DURING THE DAY WEDNESDAY...ANOTHER DEEPER PV CORE PRESSES EAST INTO THE ERN LAKES WED PM AND AS A RESULT NY AND PA FALLS UNDER STRG CAA AT 500 MB. THIS WILL OCCUR ABV SOME RESIDUAL LL MOISTURE LEADING TO SOME CAPE WITH THE AFTERNOON INSOLATION. THE 12Z GFS...12Z NAM AND 00Z EURO ALL HAVE SOME POPCORN LIKE SHRA AND ISLD TSRA AS PER MODEL SOUNDINGS FORMING WITH THE AFTERNOON HEATING. THE ACVTY WILL BE SCT IN NATURE SO CHC POPS ARE IN STORE. FOR WED NGT/THURSDAY...SFC HIGH PRESSURE BUILDS ACRS THE ERN LAKES TO NY AND UPR LVL TROF SHEARS OUT UNDERNEATH DEEPER UPPER LEVEL LOW ACRS ERN CANADA. THERE SHUD BE ENUF SUBSC TO SQUASH ANY THREAT FOR SHRA BY LATER WED NGT INTO THURSDAY. WILL TAPER DOWN POPS FOR SHRA WED EVE...AND HAVE NO POPS FOR THU. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... FOLLOWED WPC GUIDC WITH TWEAKS MADE TO COLLABORATE WITH OUR NEIGHBORING WFO/S. BASIC PATTERN IS HIGH PRESSURE COVERS THE REGION THRU FRI NGT. THIS HIGH WILL SHIFT OFF THE EAST COAST FOR THE WEEKEND WITH A RETURN FLOW INCREASING MOISTURE AND INSTABILITY IN TIME. NEXT UPPER LEVEL WAVE AND ASSTDC SFC WAVE WILL BRING CHC FOR SHRA/TSRA BY SUNDAY BUT THERE IS SOME DIVERGENCE IN THE MODEL SOLTNS AS TO TIMING. FOR NOW HAVE SLGHT CHC SAT INCREASING TO CHC FOR SHRA/TSRA BY SUN. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... 18Z UPDATE... MAINLY VFR WITH SW WINDS ROUGHLY 10G20KT...BUT BRIEF RESTRICTIONS POSSIBLE FROM SCATTERED THUNDERSTORMS THIS AFTERNOON THROUGH EARLY EVENING...AS NOTED VIA TEMPO GROUPS. SEE INDIVIDUAL TAFS FOR SPECIFICS ON TIMING FOR EACH TERMINAL. ANY TERMINAL TAKING DIRECT HIT FROM ONE OF THE CELLS COULD HAVE STRONG GUSTS GREATER THAN 25 KTS...PRIMARILY FROM SW OR W DIRECTION. WITH EARLIER SHOWERS AND EMBEDDED THUNDER HAVING ALREADY GONE THROUGH KSYR-KRME...THERE WILL PROBABLY NO LONGER BE ENOUGH INSTABILITY THERE TO SUPPORT ADDITIONAL TSRA THIS AFTERNOON-EVENING...BUT THINGS WILL STILL NEED TO BE MONITORED CLOSELY. WINDS BECOME LIGHT TONIGHT ALONG WITH DISSIPATION OF SHRA/TSRA...BUT VALLEY FOG AND/OR MVFR CIG POSSIBLE FOR SEVERAL TERMINALS. WINDS AGAIN PICKING UP OUT OF THE SW TUESDAY...BUT CHANCES FOR TSRA WILL BE MAINLY AFTER 18Z. OUTLOOK... LATE TUE THROUGH WED..VFR MAJORITY OF THE TIME...BUT RESTRICTIONS MAY OCCUR FROM SCT SHRA/TSRA ESPECIALLY AFTN-EVE HRS. THU-FRI-SAT...MAINLY VFR...EXCEPT PREDAWN VALLEY FOG KELM. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...NONE.
