The episode as NWS ALY wrote it up.
A very warm and humid air mass was in place across eastern New York on Tuesday, May 21st. A slow moving frontal boundary was situated just north of the area across the Saint Lawrence River Valley along the United States-Canadian border. During the day, a wave of low pressure moved along this boundary, allowing the boundary to slowly push southward towards the area. With strong wind shear aloft and plenty of low level moisture in place, thunderstorms developed during the early afternoon hours.
Thunderstorms initially formed as single cells and supercells, but eventually organized into several broken lines, which moved from west to east across the area. Many of these storms produced wind damage to trees and power lines. In addition, some thunderstorms produced hail, with hailstones as large as 2.50 inches in diameter across Columbia County.
As the surface wave of low pressure moved away and with the loss of daytime heating, thunderstorms eventually ended during the late evening hours.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Albany, NY wrote its last area forecast discussion before the first event at May 21, 1:01 PM EST, 1 hour 6 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 201 PM EDT TUE MAY 21 2013 .SYNOPSIS... WARM AND HUMID CONDITIONS WILL CONTINUE THIS AFTERNOON WITH A FRONTAL BOUNDARY BECOMING STATIONARY OVER NORTHERN NEW YORK AND NORTHERN NEW ENGLAND. A DISTURBANCE MOVING ALONG THE FRONTAL BOUNDARY WILL FOCUS SOME SHOWERS AND POTENTIALLY STRONG THUNDERSTORMS DURING THE MID AFTERNOON AND EARLY EVENING HOURS. THE HUMID AND UNSETTLED WEATHER CONTINUES TOMORROW AND THURSDAY WITH MORE CHANCES OF SHOWERS AND THUNDERSTORMS BEFORE A COLD FRONT RETURNS DRIER AND COOLER WEATHER FOR FRIDAY AND INTO THE HOLIDAY WEEKEND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... SEVERE THUNDERSTORM WATCH UNTIL 9 PM EDT FOR EASTERN NEW YORK AND WESTERN NEW ENGLAND... AS 145 PM EDT...AFTER COORDINATION WITH SPC AND WFO BGM AND BUF THE ENTIRE FORECAST AREA IS IN A SEVERE THUNDERSTORM WATCH FOR THE POTENTIAL OF LARGE HAIL /1 INCH AND GREATER/ AND DAMAGING WINDS. THERE IS SOME UNCERTAINTY IN THE COVERAGE FOR SEVERE...BUT AIR MASS IS EXTREMELY UNSTABLE SOUTH OF THE CAPITAL REGION...AS DESCRIBED BELOW. THE AIR MASS HAVE BECOME INCREASINGLY UNSTABLE IN THE WARM SECTOR EARLY THIS PM WITH TEMPS GETTING CLOSE TO CONVECTIVE TEMPS...AND ISOLD TO SCT CONVECTION FIRING OVER WRN- CNTRL NY. TEMPS HAVE BEEN RAISED TO THE MID AND U80S OVER PORTIONS OF THE CAPITAL REGION...AND THE MID HUDSON VALLEY. THERE MAYBE A FEW READINGS CLOSE TO 90F TOO NEAR KPOU. ELSEWHERE TEMPS WILL CONTINUE TO RISE INTO THE U70S TO M80S. ALSO...SFC DEWPTS HAVE RISEN INTO THE MID AND U60S OVER A LARGE PORTION OF THE FCST. THE LATEST SPC MESO ANALYSIS PAGE INDICATES SBCAPES HAVE REACHED 2000-3000+ J/KG FROM THE CAPITAL DISTRICT SOUTH AND EAST...AND LESS INSTABILITY NORTHWARD /1000-2000 J/KG/. THE 0-6 KM BULK SHEAR ARE NOT OVERLY IMPRESSIVE IN THE SRN ZONES WITH LESS THAN 20 KTS...BUT TO THE NORTH THE SHEAR VALUES ARE 30-35 KTS. THEREFORE...BETTER...DEEP ORGANIZED CONVECTION...IS POSSIBLE FROM THE CAPITAL REGION NORTH...WITH PULSE CONVECTION TO THE SOUTH. MID LEVEL LAPSE RATES ARE APPROACHING THE 6.5 C/KM RANGE. THE ABUNDANCE OF INSTABILITY AND STEEPENING LAPSE RATES WILL PROMOTE SOME LARGE HAIL POTENTIAL TOO. NOW...UPSTREAM...A POSSIBLE REMNANT MCV IS MOVING ACROSS SE ONTARIO. THIS FEATURE SHOULD BE THE FOCUSING MECHANISM FOR POSSIBLE SEVERE CONVECTION /ASIDE FROM THE PULSE CONVECTION/. THE 12Z KALB SOUNDING DOES INDICATE A MID LEVEL CAP BTWN 500-550 HPA THAT WILL NEED TO BE ERODED FOR ROBUST SEVERE WEATHER. THE UPSTREAM CONVECTION IS HOLDING TOGETHER...SO THIS CAP COULD BE BROKEN. THE LATEST MAGLENTA INDEX INDICATES A MAJOR SEVERE EVENT /HINGING ON THE LARGE CAPE VALUES/. CAPE=2000 J/KG (APPROX) MAX SOUNDING WIND=40 KTS EHI=0.5 STORM SPEED=20 KTS SRH=125 THINKING HAS CHANGED FOR A MINOR TO MAJOR EVENT BASED ON THE VOLATILE THERMODYNAMIC ENVIRONMENT. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/... ONGOING CONVECTION THIS EVENING LOOKS TO CONTINUE INTO TONIGHT AS THE SFC WAVE MOVES ALONG THE BOUNDARY. THE BEST CHC FOR SEEING SHOWERS/TSTMS WILL BE ACROSS THE NORTHERN PORTION OF THE AREA. WITH THE LOSS OF HEATING...ANY SVR THREAT WILL BE DIMINISHED...BUT THUNDER SHOULD STILL CONTINUE DUE TO LINGERING ELEVATED INSTABILITY OVERNIGHT. MIN TEMPS WILL CONTINUE TO BE MILD AND MUGGY WITH UPPER 50S TO MID 60S ACROSS THE AREA. THE SFC BOUNDARY WILL LIFT NORTHWARD AS A WARM FRONT ON WEDNESDAY. THE RIDGE AXIS WILL START TO SHIFT EASTWARD AS THE UPPER LOW OVER THE PLAINS SLOWLY MOVES EASTWARD. DESPITE THE WEAK LARGE SCALE FORCING...THERE LOOKS TO BE A CONTINUED THREAT FOR SHOWERS/TSTMS AS A PRE FRONTAL TROUGH MAY BE IN PLACE ACROSS OUR AREA BY AFTN. PLENTY OF MOISTURE AND INSTABILITY WILL BE IN PLACE...ESP WITH WARM TEMPS REACHING THE 80S IN MOST AREAS...AND TDS IN THE MID 60S F. ANY STORM WILL AGAIN BE CAPABLE OF PRODUCING DAMAGING WINDS/LARGE HAIL...AND SPC HAS PLACED A GOOD CHUNK OF OUR AREA IN A SLIGHT RISK FOR SVR STORMS. WILL HIGHLIGHT THIS IN THE HWO AS WELL. SHOWERS AND THUNDERSTORMS MAY LINGER AGAIN INTO WEDNESDAY NIGHT WITH CONTINUED MILD AND MUGGY CONDITIONS. MINS WILL ONLY DROP INTO THE 60S...WITH MID TO UPPER 60S IN THE HUDSON VALLEY. THE UPPER TROUGH WILL FINALLY BEGIN TO MAKE SOME STEADY EASTWARD PROGRESS ON THURSDAY INTO THURSDAY NIGHT. A SFC COLD FRONT WILL ADVANCE EASTWARD DURING THIS TIME AS WELL. THIS FRONT WILL BE A FOCUS FOR ADDITIONAL SHOWERS AND THUNDERSTORMS...ESP FOR THURSDAY AFTN INTO THURSDAY NIGHT. AHEAD OF THIS BOUNDARY...THERE WILL BE ONE LAST WARM AND MUGGY DAY...WITH MAX TEMPS IN THE 70S. MIN TEMPS WILL START TO COOL OFF BY THURSDAY NIGHT WILL THE BOUNDARY MOVING THROUGH...WITH MINS IN THE 40S AND 50S ACROSS THE AREA...WITH THE MILDEST TEMPS IN SOUTHEASTERN AREAS. && .LONG TERM /FRIDAY THROUGH MONDAY/... A COLD FRONT SHOULD EXIT THE REGION THROUGH THE DAY FRIDAY WITH LINGERING SHOWERS AND THUNDERSTORMS IN THE MORNING IN NY AND INTO THE AFTERNOON IN WESTERN NEW ENGLAND. THERE SHOULD BE DECENT BOUNDARY LAYER FORCING WITH A TIGHT THERMAL AND MOISTURE GRADIENT ALONG THE COLD FRONT...SO WILL KEEP AN EYE FOR ANY STRONG THUNDERSTORM POTENTIAL. BOUNDARY LAYER TEMPERATURES SHOULD FALL THROUGH THE DAY...AND HIGH TEMPERATURES SHOULD BE CAPPED AROUND THE MID 60S TO AROUND 70...BUT IN THE MID TO UPPER 50S IN THE SOUTHERN ADIRONDACKS. ONCE THE COLD FRONT IS GONE...HIGH PRESSURE GRADUALLY BUILDS IN THROUGH THE WEEKEND AND INTO THE BEGINNING OF NEXT WEEK. SOME LINGERING CLOUDINESS COULD AFFECT THE MID HUDSON VALLEY INTO WESTERN NEW ENGLAND SATURDAY AS THE COLD FRONT COULD BE SLOW TO EXIT THOSE AREAS. HOWEVER...ANY SHOWER ACTIVITY SHOULD REMAIN EAST OF OUR AREA. HIGHS SATURDAY IN THE MID TO UPPER 60S...UPPER 50S SOUTHERN ADIRONDACKS. FOR SUNDAY AND MONDAY...INCREASING SUNSHINE AND SLOWLY MODERATING TEMPERATURES. HIGHS SUNDAY IN THE UPPER 60S TO AROUND 70 AND ON MONDAY...HIGHS AROUND 70 TO THE LOWER 70S. TEMPERATURES COOLER IN THE SOUTHERN ADIRONDACKS BOTH DAYS. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... MORE SHOWERS AND THUNDERSTORMS WEST OF THE FA ALONG WITH SOME WHICH DEVELOP ACRS THE FA THIS AFTERNOON COULD AFFECT THE TAF SITES LATE THIS AFTERNOON AND EVENING. DUE TO UNCERTAINTIES OF ANY STORM IMPACTING THE TAF SITES...JUST PLACING VCSH AT ALL SITES THIS AFTERNOON AND EVENING. LATER IN THE EVENING...SOME FOG AND LOW CEILINGS COULD POTENTIALLY FORM WITH MVFR CONDITIONS. THIS WILL BREAK WEDNESDAY MORNING WITH THE POTENTIAL FOR MORE SHOWERS AND THUNDERSTORMS TOWARD MIDDAY...SO HAVE PLACED VCSH IN TAFS AT 15Z WED. LIGHT WINDS SHOULD BECOME SOUTH TO SOUTHWEST AT 10 KT OR LESS TODAY...THEN DIMINISH BACK TO LIGHT THIS EVENING AND TONIGHT AND THEN BECOME SOUTH TO SOUTHWEST AT 5 TO 7 KTS ON WEDNESDAY MORNING.

NO WIDESPREAD HYDRO SERVICE AREAS PROBLEMS ARE EXPECTED THE NEXT 5 DAYS. SOME LOCALLY HEAVY DOWNPOURS OF RAINFALL MAY OCCUR TODAY THROUGH THURSDAY WITHIN ANY THUNDERSTORMS. 3-HR ZONAL FFG VALUES ARE GENERALLY IN THE 2.4-3.1 INCH RANGE AT THIS TIME...WHICH ARE HIGH FOR MID TO LATE MAY. DUE TO THE SCATTERED NATURE OF THE SHOWERS AND THUNDERSTORMS... BASIN AVERAGE QPF WILL BE HIGHLY VARIABLE THIS WEEK.
