A developing upper level trough, combined with several weak surface boundaries, led to the development of numerous showers and thunderstorms during Sunday afternoon and evening on June 22nd, some of which became severe. Additional isolated severe thunderstorms developed late Sunday night, into the early morning hours of Monday June 23rd.

NWS Albany, NY wrote its last area forecast discussion before the first event at Jun 22, 5:54 AM EST, 3 hours 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 654 AM EDT SUN JUN 22 2008 .SYNOPSIS... SEVERAL DISTURBANCES IN ADVANCE OF AN UPPER LEVEL LOW OVER SOUTHERN ONTARIO AND THE GREAT LAKES REGION WILL PRODUCE PERIODS OF SHOWERS AND THUNDERSTORMS TODAY THROUGH MONDAY. SOME OF THE THUNDERSTORMS MAY BECOME STRONG TO SEVERE. THE OCCLUDED FRONT TO THE SYSTEM WILL MOVE EAST OF THE REGION MONDAY NIGHT INTO TUESDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... THE KENX/MOSAIC RADAR THIS MORNING SHOWS A BAND OF SHOWERS AND THUNDERSTORMS SLOWLY MOVING N/NE ACROSS CNTRL NY...INTO NRN AND ERN NY IN ASSOCIATION WITH A THERMAL/PREFRONTAL TROUGH. SOME CONVECTION CONTINUES IN THIS BAND. CONVECTIVE PARCELS APPEAR TO BE ELEVATED IN NATURE...BUT SHOULD TRANSITION TO SURFACE BASE BY THE LATE MORNING ACCORDING TO BUFKIT GUIDANCE. A VERY NEBULOUS AND MURKY SEVERE WEATHER POTENTIAL FOR THE LATE MORNING AND AFTERNOON WITH FORECASTER CONFIDENCE LOW. SPC CONTINUES A SLIGHT RISK FOR THE FCST AREA. IT APPEARS THE MORNING CONVECTION MAY PRODUCE SOME OUTFLOW BOUNDARIES THAT MAY FOCUS MULTICELLULAR CONVECTION THAT FORMS MULTIPLE LINES BASED ON THE UNIDIRECTIONAL SOUTHWESTERLY WIND PROFILE /850-300 HPA/ ON THE EAST SIDE OF AN UPPER LEVEL H500 TROUGH OVER S-CNTRL ONTARIO AND THE GREAT LAKES REGION. IT IS INTERESTING THAT SFC DEWPOINTS UPSTREAM OF THIS BAND OF SHOWERS AND THUNDERSTORMS ARE STILL ONLY IN THE MID AND UPPER 50S. CAREFUL INSPECTION OF GFS/NAM MODEL SOUNDING GUIDANCE IS SHOWING WIDESPREAD 60S /IN SOME CASES MID AND UPPER 60S BY THE PM/. THESE DEWPOINTS ARE PRODUCING SFC BASED INSTABILITY VALUES IN THE 1000-2000 J/KG RANGE. WE BELIEVE THE BATCH OF SHRAS/TSRAS UPSTREAM WILL HELP MOISTEN THE BOUNDARY LAYER TO PRODUCE DEWPOINTS IN THE U50S TO L60S OVER THE FCST AREA. HOWEVER...HEIGHT FALLS AND STEEP MID LEVEL LAPSE RATES ARE LACKING TODAY. ALSO...DEEP BULK SHEAR IN THE 0-6 KM LAYER IS ONLY ABOUT 30 KTS. AGAIN...ANY MULTICELLULAR CONVECTION WILL LIKELY FORM INTO A LINE. IT MAY BE AN EARLY SHOW WITH ANY STRONG TO SEVERE TSRAS OCCURRING IN THE LATE MORNING THROUGH THE MID AFTERNOON. OUR LOCAL MAGLENTA SEVERE WEATHER CONDITIONAL INDEX YIELDS A MINOR SEVERE DAY /LESS THAN 10 EVENTS/ POSSIBLE WITH THE FOLLOWING VALUES ENTERED: SBCAPE=1200 J/KG /THIS MAY BE TOO HIGH/ MAX SOUNDING WIND = 60 KTS EHI = 0.4 0-3KM SREH = 80 STORM MOTION = 25KTS THE UPPER LEVEL DIVERGENCE FROM THE GFS IS GREATEST BETWEEN 1800-0000 UTC OVER WRN-CNTRL NEAR THE LEFT FRONT QUADRANT OF AN H250 80-95 KT JET STREAK OVER LOWER 0H-WRN PA. THE BEST H850 LLJ OF 25-30 KTS MOVES THROUGH BY 1800 UTC. THE WET BULB ZERO HEIGHTS ARE IN THE 8.5-10 KFT RANGE...WHICH IS ABOUT NORMAL FOR MID-LATE JUNE. THE BEST SEVERE THREAT WILL BE DAMAGING WINDS. WE ADDED ENHANCED WORDING OF SMALL HAIL...GUSTY WINDS...AND HEAVY RAINFALL TO THE GRIDS. PRECIPITABLE WATER VALUES RISE BACK TO 1-1.5 INCHES...SO SOME BURSTS OF HEAVY RAINFALL ARE POSSIBLE THROUGHOUT THE DAY...AS THE AIR MASS GETS MORE HUMID. GFSMOS HIGH TEMPS LOOKED PRETTY GOOD. && .SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/... SUNDAY NIGHT...ANY SHOWERS AND THUNDERSTORMS SHOULD BEGIN TO DECREASE IN THE EARLY EVENING WITH SOME PATCHY FOG FORMING...AS THE SKIES WILL LIKELY BECOME PARTLY CLOUDY. A MID AND UPPER JET MAX BEGINS TO INCH CLOSE TO THE FCST AREA FROM THE SOUTH AND WEST TOWARDS 1200 UTC...AND THIS MAY ACTUALLY INCREASE THE CHANCES FOR SVR WEATHER FROM THE CAPITAL DISTRICT...SRN VT...AND THE CATSKILLS SOUTHWARD FOR MONDAY. SPC DAY 2 LOOKS ACTUALLY PRETTY GOOD. MONDAY...THE SHORT TERM MODEL GUIDANCE INDICATES THE OCCLUDED FRONT ASSOCIATED WITH THE POSITIVELY TILTED UPPER LEVEL TROUGH UPSTREAM MAY TRIGGER ANOTHER ROUND OF STRONG TO SEVERE THUNDERSTORMS. A MOIST AND UNSTABLE AIR MASS WILL BE IN PLACE WITH EVEN SOME DECENT SOLAR HEATING DURING THE MORNING THAT A CLUSTER/LINE OF SEVERE THUNDERSTORMS MAY OCCUR. AN 250 HPA JET STREAK OF 90-100 KTS WILL BE OVER CNTRL-ERN PA...ERN NY...AND WRN NEW ENGLAND. THE DEEP SHEAR LOOKS BETTER WITH AROUND 50 KTS POTENTIALLY REALIZING SURFACE BASED INSTABILITY OF 1000-2000 J/KG...SO LARGE HAIL AND BOWING SEGMENTS ALONG A LINE MAY BE POSSIBLE. WE WILL CONTINUE TO MENTION THE SEVERE THREAT IN THE HAZARDOUS WEATHER OUTLOOK. MONDAY NIGHT...THE OCCLUDED BOUNDARY SHOULD MAKE STEADY PROGRESS ACROSS ERN NY WITH SHOWERS AND THUNDERSTORMS TAPERING AROUND MIDNIGHT. WE TENDED TO LOWER THE POPS TO SLIGHT CHANCE VALUES AFTER 0400 UTC TUE. SFC HIGH PRESSURE BEGINS TO BUILD IN FROM THE MIDWEST TUESDAY MORNING...THE UPPER TROUGH AXIS STILL WILL LINGER OVER ERN NY/WRN NEW ENGLAND ON TUE. && .LONG TERM /TUESDAY THROUGH SATURDAY/... UPPER TROUGH AXIS FINALLY MOVES OFF TO THE EAST TUESDAY EVENING. WILL HAVE LINGERING THREAT FOR CONVECTIVE TUESDAY. FLOW BECOMES FLATTENED ACROSS THE NORTHERN TIER OF THE UNITED STATES FOR MID WEEK WITH HIGHER PRESSURE BUILDING IN AT THE SURFACE. IMPULSES WILL MOVE THROUGH QUICK FLOW WITH THE SURFACE RIDGE GETTING SUPPRESSED. THE NEXT MAIN SHORT WAVE MOVES ACROSS WESTERN CANADA WITH A TROUGH DIGGING ACROSS THE GREAT LAKES REGION NEXT WEEKEND AND A RIDGE BUILDING OVER THE PLAINS. THE MODELS DIFFER WITH HOW AMPLIFIED THE PATTERN WILL GET. THE ECMWF IS THE MOST ROBUST. GENERALLY...FINALLY LOOKING AT DRY WEATHER FOR TUESDAY NIGHT THROUGH WEDNESDAY NIGHT WITH CHANCES FOR SHOWERS AND THUNDERSTORMS RETURNING FOR LATE IN THE WEEK INTO NEXT WEEKEND. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... A SFC TROUGH ASSOCIATED WITH AN UPPER LEVEL LOW OVER THE NRN GREAT LAKES REGION WILL CONTINUE TO BRING SHOWERS AND THUNDERSTORMS TO ERN NY AND WRN NEW ENGLAND PRIMARILY BETWEEN 1200 UTC SUN TO 0000 UTC MON. MULTICELLULAR CONVECTION WILL EVOLVE INTO A SLOW MOVING LINE OF STRONG TO POTENTIALLY SEVERE THUNDERSTORMS IN THE LATE MORNING INTO THE EARLY PM. WE ADDED A TEMPO FOR A TSRA AT KALB AND KGFL BTWN 12-14 UTC BASED ON THE RADAR TRENDS. WE INCLUDED A VCTS AT KPOU AROUND 1400 UTC. WE STILL INCLUDED CB/S FOR NOW UNTIL THE CONVECTIVE DETAILS BECOME MORE CLEARER OVER THE NEXT 3 TO 6 HOURS FOR THE AFTERNOON TIME FRAME. THERE IS A GOOD BET FOR MVFR VSBYS AT ALL THE TAF SITES PRIOR TO AND SHORTLY AFTER 1800 UTC IN THE SHOWERY ACTIVITY. THE SHOWERS AND THUNDERSTORMS SHOULD DIMINISH AFTER 0000 UTC MON. THE WINDS WILL GENERALLY BE S/SE AT 5-10 KTS AFTER 1200 UTC...WITH A FEW GUSTS CLOSE TO 20 KTS AT KALB. THE WINDS WILL RELAX AFTER 0000 UTC AND WILL BECOME LIGHT TO CALM AT 5 KTS OR LESS. SOME MVFR/IFR RADIATIONAL MIST/FOG IS POSSIBLE AT ALL SITES DEPENDING ON THE AMOUNT OF CLEARING IN THE WAKE OF THE SFC TROUGH. OUTLOOK... MON...VFR/MVFR...CHC OF SHRA/TSTMS. TUE...VFR...CHC OF PM -SHRA/TSTMS. WED...VFR...NO SIG WX. THU...VFR...CHC -SHRA/TSTMS. && .FIRE WEATHER... SEVERAL DISTURBANCES ASSOCIATED WITH AN UPPER LEVEL TROUGH WILL PRODUCE SHOWERS AND THUNDERSTORMS THROUGH MONDAY. AN OCCLUDED FRONT WILL CLEAR MOST OF THE REGION MONDAY NIGHT INTO TUESDAY. WET FLAG CONDITIONS ARE LIKELY THIS AFTERNOON. RH VALUES WILL ONLY FALL TO 60 TO 75 PERCENT TODAY...AND THEN RECOVER TO 85 TO 100 PERCENT SUNDAY NIGHT. RH VALUES WILL FALL TO 50 TO 70 PERCENT MONDAY AFTERNOON. SURFACE WINDS OF 5 TO 15 MPH WILL BE COMMON FROM THE SOUTH TODAY WITH A FEW GUSTS TO 25 MPH. THE WINDS WILL BECOME LIGHT AND VARIABLE SUNDAY NIGHT. SOUTH OR SOUTHWEST WINDS OF 10 TO 15 MPH WILL OCCUR ON MONDAY. GUSTY WINDS IN EXCESS OF 30 MPH ARE POSSIBLE WITH ANY THUNDERSTORMS. && .HYDROLOGY... THE NEXT FEW DAYS WILL FEATURE PERIODS OF SHOWERS AND THUNDERSTORMS. PRECIPITABLE WATER VALUES WILL RISE TO ABOUT 150% OF NORMAL IN SOME LOCATIONS. HEAVY DOWNPOURS FROM THUNDERSTORMS ARE LIKELY WITH ONE TO TWO INCHES OCCURRING IN SOME LOCATIONS. OVERALL...MAIN STEM RIVERS WILL NOT HAVE SIGNIFICANT RISES. HOWEVER...SOME SMALL CREEKS AND STREAMS MAY REACH BANKFULL IN PERSISTENT OR HEAVY RAINFALL TODAY AND TOMORROW. SOME RURAL/URBAN AND SMALL STREAM ADVISORIES MAY BE NECESSARY...BUT FLOODING IS NOT EXPECTED. A DRIER AIR MASS WILL BUILD IN BY MID WEEK. && .ALY WATCHES/WARNINGS/ADVISORIES... CT...NONE. NY...NONE.
