The episode as NWS ALY wrote it up.
A strong area of high pressure was located just off the eastern seaboard. Southerly flow around this high pressure area brought warm and moist air into the region during the day of Sunday, June 23rd. At the same time, a weak surface frontal boundary was located just north of the area along the U.S. and Canadian International Border. As an upper level wave moved by to the north, showers and thunderstorms developed across the western Mohawk Valley during the afternoon hours. With the moist air in place, the showers and thunderstorms produced very heavy rainfall in a short period of time. With the ground already saturated due to wet conditions over the past several weeks, this led to flash flooding across southern portions of Herkimer County, as small stream and creeks left their banks. Several roads were washed away and many roads, including some state roads, were closed due to the flooding. Some homes were impacted by flood waters as well. Newspaper media stated the cost of the damage could exceed 1$ million.

NWS Albany, NY wrote its last area forecast discussion before the first event at Jun 23, 12:45 PM EST, 1 hour 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 145 PM EDT SUN JUN 23 2013 .SYNOPSIS... A WARM AND HUMID AIR MASS WILL CONTINUE THIS AFTERNOON THROUGH THE MIDDLE OF NEXT WEEK. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE IN THE AFTERNOON AND EARLY EVENING THE NEXT FEW DAYS. SOME LOCALLY HEAVY RAINFALL WILL BE POSSIBLE...AND PATCHY FOG WILL BE COMMON WITH MUGGY CONDITIONS EACH NIGHT. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... AS OF 130 PM EDT...CONVECTION HAS INITIATED ALONG THE DIFFUSE FRONTAL BOUNDARY ACROSS NORTHERN NY AND WESTWARD ALONG THE LAKE BREEZE BOUNDARY AND INTO THE FINGER LAKES REGION. EXPERIMENTAL WRF REFLECTIVITIES SUGGEST MORE UPSCALE GROWTH TO CONTINUE AS SBCAPES PER LAPS/SPC-MESOSCALE WINDOW ARE CLOSE TO 3K J/KG. IN FACT...SPC HAS INCREASED OUR PROBABILITIES INTO A SLIGHT RISK FOR SEVERE WEATHER WITH THE RECENT SWOMCD HINTING AT THE POTENTIAL FOR A WATCH. BEST SHEAR REMAINS MAINLY TO OUR NORTH AND MID LEVEL LAPSE RATES REMAIN LESS THAN IDEAL FOR VIGOROUS UPDRAFTS...HOWEVER...WITH DEWPOINTS NOW HOVERING NEAR 70F AND TEMPS NEAR 90F THE ENVIRONMENT IS CONDUCIVE FOR CELLULAR STRUCTURES AND/OR SMALL BOWS ALONG THE COLD POOL THAT IS GENERATED. AS OF 1026 AM EDT...A DIFFUSE FRONTAL BOUNDARY CONTINUES TO BE NORTH OF THE FORECAST AREA THIS MORNING. SOME SHOWERS AND THUNDERSTORMS MOVED ACROSS THE SOUTHERN ADIRONDACKS EARLY THIS MORNING...LEAVING UP TO AN INCH OF RAINFALL /ACCORDING TO RADAR ESTIMATES/ IN SPOTS NEAR INDIAN LAKE. THE FRONTAL BOUNDARY WILL CONTINUE TO LIFT NORTHWARD DURING THE DAY...AS A SUBTROPICAL HIGH OFF THE MID ATLANTIC COAST AT THE SFC...AND ALOFT CONTINUES TO FUNNEL HUMID AIR NORTHWARD. SFC DEWPTS TODAY WILL RISE INTO THE MID AND U60S IN SOME LOCATIONS WITH SOUTH TO SOUTHWEST SFC LAYER WINDS. H850 TEMPS INCREASE TO +16 TO +17C WITH PARTLY TO MOSTLY SUNNY CONDITIONS. MAX TEMPS IN THE M80S TO NEAR 90F WILL BE LIKELY IN THE VALLEYS WITH U70S TO L80S OVER THE MTNS. WEAK MID LEVEL VORTICES MOVING ALONG THE RIM OF THE UPPER LEVEL RIDGE MAY TRIGGER SOME ISOLD-SCT THUNDERSTORMS TODAY. THE BEST 0-6 KM BULK SHEAR IS ACTUALLY JUST NORTH OF THE FCST AREA ACROSS NRN NY AND NRN NEW ENGLAND WITH 20-30 KTS. MOST OF THE ALY FCST AREA WILL BE IN A WEAK SHEAR ENVIRONMENT OF 10-20 KTS FOR PULSE OR VERY LOOSELY ORGANIZED THUNDERSTORMS. FREEZING LEVELS WILL BE HIGH IN THE 12-14 KFT AGL RANGE WITH WBZ HEIGHTS AROUND 11 KFT AGL. SBCAPES WILL BE IN THE 500-1500 J/KG RANGE ACCORDING TO THE GFS. NOT BUYING INTO THE NAM/S FAIRLY WIDESPREAD LOWER 70S DEWPT AIR OVER THE REGION WITH SBCAPES OF 2000-3000 J/KG. THE NEW 12Z NAM...AS WELL AS THE 12Z 3KM HRRR AND THE 12Z LOCAL HIRES WRF SHOW CELLULAR CONVECTION POPPING UP ACROSS THE ADIRONDACKS BY THE EARLY TO MID AFTN...AND MORE ACTIVITY DEVELOPING AND MOVING ACROSS THE MOHAWK VALLEY...CAPITAL REGION AND SRN VT...BY THE MID/LATE AFTN AND INTO THE EVENING HOURS. EACH MODEL HAS THE PLACEMENT/TIMING SLIGHTLY DIFFERENT...BUT THE CONVECTIVE MODE /CELLULAR PULSE TYPE STORMS/ SEEMS TO BE SIMILAR IN EACH MODEL. THIS MORNING/S 12Z KALY SOUNDING SHOWED A PWAT OF 1.62. AS A RESULT...A MENTION OF HVY RAIN HAS BEEN INCLUDED WITH ISOLD-SCT THUNDERSTORMS TODAY IN THE GRIDDED...TEXT FORECASTS...AND HWO STATEMENT. AN ISOLD SEVERE MAY BE POSSIBLE TOO...ESPECIALLY IN THE NRN ZONES...BUT THE FORECASTED WEAK MID LEVEL LAPSE RATES OF LESS THAN 6 C/KM AND LIMITED AMOUNTS OF SHEAR IN THE 0-6 KM LAYER SHOULD PROHIBIT WIDESPREAD STRONG CELLS. SPC MAINTAINS A /SEE TEXT/ AREA ACROSS THE CENTRAL/NORTHERN PART OF THE CWA AND WE WILL CONTINUE TO MONITOR MESOSCALE TRENDS. && .SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/... TONIGHT...THE ISOLD TO SCT CONVECTION SHOULD SHRIVEL UP QUICKLY BEFORE MIDNIGHT WITH THE LOSS OF THE DAYTIME HEATING. A PARTIAL CLEARING WILL ALLOW PATCHY FOG JUST ABOUT ANYWHERE IN THE FCST AREA WITH THE MOIST LOW LEVELS. IT HAS BEEN ADDED TO THE FORECAST GRIDS. STICKY CONDITIONS WILL PREVAIL WITH LOWS IN THE MID AND U60S IN THE VALLEYS...AND LOWER TO M60S OVER THE HILLS AND MTNS. MONDAY...THE SULTRY CONDITIONS IN PLACE WILL PROMOTE INCREASED CHANCES OF MORE PULSE THUNDERSTORMS WITH DEEP SHEAR VALUES LESS THAN 15 KTS. SBCAPES WILL SOLIDLY BE IN THE 1000-2000 J/KG RANGE. SOME THUNDERSTORMS MAY BE SLOW MOVERS OR LATCH TO THE TERRAIN FOR A QUICK INCH OR TWO OF RAINFALL IN THE ANOMALOUSLY HIGH PWAT AIR MASS. THE NAM SHOWS HINTS OF A SHORT-WAVE TROUGH IN THE W/SW ALOFT MOVING THROUGH DURING THE AFTERNOON. THE ECMWF/GFS ALSO SHOW A SUBTLE SHORT-WAVE TROUGH IN THE FLOW ALOFT. THE MID LEVEL LAPSE RATES STEEPEN TO AROUND 6.5C/KM ON THE GFS. 850HPA THETA-E VALUES INCREASE TO CLOSE TO 340K ACROSS PORTIONS CNTRL-ERN NY. THE THETA-E RIDGE WEAKENS SLIGHTLY TOWARDS NIGHT FALL WITH THE PASSAGE OF THIS TROUGH. HVY RAIN HAS BEEN INCLUDED WITH THE THUNDERSTORMS AGAIN IN THE GRIDS/TEXT PRODUCTS. H850 TEMPS INCREASE CLOSE TO +17 TO +18C WITH THE GFSMOS TEMPS MUCH WARMER THAN THE METMOS TEMPS. A BLEND WAS USED WITH A SHADING A LITTLE CLOSER TO THE GFSMOS VALUES WITH SOUTHWEST TO WEST WINDS IN THE SFC TO BOUNDARY LAYER...TEMPS MAY SPIKE UP A LITTLE BIT IN THE VALLEYS DUE TO DOWNSLOPING WITH HIGHS IN THE U80S TO L90S WITH U70S TO M80S OVER THE HILLS AND MTNS. APPARENT TEMPS COULD GET INTO M90S OR EVEN A FEW U90S IN THE MID HUDSON VALLEY. MONDAY NIGHT...SOME SUBSIDENCE OR DRYING ALOFT IN THE WAKE OF THE TROUGH WILL ALLOW THE SKIES TO GO AT LEAST PARTLY CLOUDY...ESPECIALLY THE NRN ZONES. PATCHY FOG WILL BE POSSIBLE AGAIN WITH LOWS IN THE 60S. TUE-TUE NIGHT...THE BROKEN RECORD FCST CONTINUES WITH DIURNAL DRIVEN ISOLD-SCT SHOWERS AND THUNDERSTORMS AGAIN. INITIAL CONVECTION WILL LIKELY BE FROM DIFFERENTIAL HEATING BTWN THE MTNS AND VALLEYS...BUT POTENTIAL LAKE BREEZES OR WEAK SFC TROUGHS UPSTREAM WILL HAVE TO BE MONITORED FOR MORE ORGANIZED CONVECTION. STILL FAVORING THE GFS IN TERMS OF SHEAR AND INSTABILITY. SBCAPES WILL LIKELY BE IN THE 1000-1500 J/KG RANGE WITH WEAKER MID LEVEL LAPSE RATES COMPARED TO MONDAY. HIGHS WILL BE SIMILAR TO MON WITH SOME L90S IN THE HUDSON RIVER VALLEY...AND WIDESPREAD 80S OVER THE FCST AREA. MUGGY CONDITIONS WILL CONTINUE OVERNIGHT WITH MID AND U60S IN THE VALLEYS...AND L60S OVER THE HIGH PEAKS. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... THE MODEL GUIDANCE AND ENSEMBLES ARE IN GOOD AGREEMENT WITH THE LONGWAVE PATTERN AND CONTINUE TO INDICATE THE SUBTROPICAL RIDGE SETTLES IN OVER THE SOUTHWESTERN UNITED STATES AND AMPLIFIES WITH TROUGHING OVER THE GREAT LAKES REGION AND NORTHEAST INCREASING. OVERALL THIS WILL RESULT IN THE WEATHER BECOMING MORE UNSETTLED OVER THE NORTHEAST AS PIECES OF SHORT WAVE ENERGY MOVE THROUGH THE TROUGH DEEPENING IT. THE DIFFERENCES IN THE GUIDANCE LIES WITH THE TIMING OF INDIVIDUAL SHORT WAVES AND THE MOVEMENT AND PLACEMENT OF BOUNDARIES. A WEAK BACKDOOR FRONT IS EXPECTED TO MOVE SOUTHWARD INTO THE REGION MID WEEK THEN RETURN BACK NORTHWARD AS A WARM FRONT LATE IN THE WEEK AS THE TROUGH DEEPENS OVER THE REGION AND A LOW PRESSURE SYSTEM APPROACHES. THE REGION IS EXPECTED TO BE IN THE WARM SECTOR OF THE SYSTEM INTO THE WEEKEND WITH THE SYSTEM'S COLD FRONT EVENTUALLY CROSSING THE REGION SATURDAY NIGHT/SUNDAY. TEMPERATURES ARE EXPECTED TO RETURN TO MORE SEASONABLE LEVELS. HOWEVER DEWPOINTS WILL REMAIN HIGH...IN THE 60S...MAKING FOR HUMID CONDITIONS. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... WITH A VERY WARM AND MUGGY AIR MASS IN PLACE...SCATTERED SHOWERS AND THUNDERSTORMS ARE DEVELOPING ACROSS NORTHERN AND WESTERN PORTIONS OF THE REGION. THERE IS THE POTENTIAL FOR THESE TSRA TO AFFECT KGFL/KALB/KPOU BY THE LATE AFTN OR EVENING HOURS...SO HAVE INCLUDED A TEMPO FOR THOSE SITES. KPOU SHOULD REMAIN FAR ENOUGH TO THE SOUTH AND CAPPED TO AVOID ANY TSTM ACTIVITY. WITHIN ANY TSTM...THERE IS THE POSSIBILITY OF A QUICK BURST OF HVY RAINFALL AND A STRONG WIND GUST AS WELL. ANY TSTM ACTIVITY SHOULD DIMINISH AFTER EVENING WITH THE LOSS OF HEATING. WITH THE HIGH DEWPOINTS AND LIGHT WINDS IN PLACE...SOME FOG WILL DEVELOP TONIGHT...ESP IF ANY TERMINALS RECEIVE ANY RAINFALL. THE SITES MOST LIKELY TO SEE IFR FOG WOULD BE KGFL/KPSF...MAINLY AFTER MIDNIGHT. ANY FOG WILL DISSIPATE SHORTLY AFTER SUNRISE ON MONDAY...ALLOWING FOR VFR CONDITIONS TO RETURN TO ALL SITES FOR MONDAY MORNING. OUTLOOK... MON PM-TUE...MAINLY VFR.

CHC -TSRA/-SHRA. && .FIRE WEATHER... A WARM AND HUMID AIR MASS WILL CONTINUE TODAY THROUGH THE MIDDLE OF NEXT WEEK. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE IN THE AFTERNOON AND EARLY EVENING THE NEXT FEW DAYS. RH LEVELS WILL REMAIN HIGH EACH NIGHT INTO THE MIDDLE OF NEXT WEEK FOR THE FORMATION OF DEW ACROSS EASTERN NEW YORK AND WESTERN NEW ENGLAND. NO FIRE WEATHER CONCERNS ARE EXPECTED AT THIS TIME. && .HYDROLOGY... FLOWS CONTINUE TO RECEDE TO LATE JUNE SEASONAL LEVELS. THE NEXT 5 DAYS WILL FEATURE ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WHICH WILL LIKELY NOT HAVE A SIGNIFICANT IMPACT ON THE MAIN STEM RIVERS. SLOW MOVING THUNDERSTORMS COULD PRODUCE A QUICK INCH OR TWO OF RAINFALL WITH HIGHER THAN NORMAL PRECIPITABLE WATER VALUES OVER THE HYDRO SERVICE AREA. SOME POOR DRAINAGE FLOODING OF LOW LYING AREAS...AND PONDING OF WATER ON ROADWAYS WILL BE POSSIBLE ANY DAY INTO THURSDAY. SOME SMALL STREAMS...CREEKS...AND BROOKS MAY REACH BANKFULL QUICKLY IN THE HEAVY RAINFALL ASSOCIATED WITH THE THUNDERSTORMS.
