The episode as NWS ALY wrote it up.
As a strong area of low pressure moved across upstate New York on Monday, July 28th, repeated rounds of thunderstorms occurred during the afternoon and evening hours. This led to flash flooding across northern Windham County, as small streams and creeks rapidly overspread their bands. In addition, the Williams River reached flood stage due to the rapid surge in water. Although the worst of the flooding remained north of Windham County in Windsor County, many residents reported this flooding to be the worst seen in the area since Tropical Storm Irene in 2011.
Cooler and less humid air worked into the area behind the front for Monday night, ending the rainfall and allowing water to recede.
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 Jul 28, 1:16 PM EST, 1 hour 29 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 216 PM EDT MON JUL 28 2014 .SYNOPSIS... LOW PRESSURE OVER THE SOUTHERN TIER OF NEW YORK...WILL MOVE NORTHEAST TO NEAR NORTHERN MAINE BY TUESDAY MORNING. THIS WEATHER SYSTEM WILL BRING CLOUDS AND SHOWERS TO THE ALBANY FORECAST AREA TODAY. A WEAK RIDGE OF HIGH PRESSURE WILL BRING MAINLY FAIR AND COOL WEATHER ON TUESDAY. ON WEDNESDAY...MOSTLY FAIR AND COOL WEATHER IS EXPECTED...BUT AN UPPER LEVEL IMPULSE MAY CAUSE A FEW AFTERNOON SHOWERS OR THUNDERSTORMS. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... ...INCLUDED SEVERE THUNDERSTORM WATCH...VALID UNTIL 8 PM... UPPER IMPULSE PIVOTING EAST NOW EARLY THIS AFTERNOON...AND TWO DISTINCT AREAS OF VORTICITY SEEN IN RADAR IMAGERY...ONE BETWEEN RME/GTB AND THE OTHER NEAR BGM. CONVECTION DEVELOPING AND INCREASING IN COVERAGE ALONG THE LEADING EDGE OF THE DEEPER CLOUDINESS IN CENTRAL/NORTHERN NY. BREAKS IN THE CLOUDS IN SOUTHERN AND EASTERN NY AND WESTERN NEW ENGLAND HAS ALLOWED TEMPERATURES TO WARM A LITTLE MORE THAN CURRENT FORECAST...SO SOME TEMPERATURE ADJUSTMENTS THROUGH THIS AFTERNOON. ADJUSTING RAIN CHANCES BASED ON RADAR TRENDS AND INCLUDING WORDING FOR GUSTY WINDS...SMALL HAIL AND HEAVY RAIN. UPPER IMPULSES LIKE THIS ONE CAN ENHANCE CHANCES FOR SEVERE THUNDERSTORMS AND LOCALIZED FLOODING...SO WILL SUGGEST AREAS OF URBAN AND SMALL STREAM FLOODING IN SOME AREAS...WITH ISOLATED FLASH FLOODING NOT OUT OF THE QUESTION...BUT NO FLASH FLOOD WATCH AT THIS TIME. ANTECEDENT RAINFALL HEAVIEST IN WESTERN MA/VT AND NORTHERN TACONICS OF NY...WHERE PRECIPITATION AMOUNTS SHOULD BE LESS THAN IN THE SCHOHARIE VALLEY...WESTERN MOHAWK VALLEY AND EASTERN CATSKILLS. INTERESTING 12Z SOUNDINGS ACROSS THE REGION WITH OBVIOUS COOLING ALOFT BETWEEN KBUF AND KALB...SO AGAIN...CHANCES FOR SEVERE ARE PRESENT BUT SHOULD BE ISOLATED...ALONG AND JUST SOUTH OF THE LEADING EDGE OF THE UPPER COMMA HEAD AND VORTICITY CENTERS SEEN ON RADAR. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... WITH THE PASSAGE OF THE SYSTEM'S COLD FRONT...THE THREAT FOR THUNDERSTORMS WILL COME TO AN END. WILL HAVE LINGERING THREAT OF SHOWERS THROUGH THE EVENING AS THE LOW IS DRAWN NORTHWARD AS THE SHORT WAVE BECOMES ABSORBED BY THE LARGE CUT OFF LOW CENTERED NEAR HUDSON'S BAY CANADA. . WITH THE PASSAGE OF THE SYSTEM COOLER AIR WILL BE DRAWN INTO THE REGION ON NORTHWEST FLOW. INTO MID WEEK THE REGION WILL BE UNDER A LONGWAVE TROUGH WITH PIECES OF ENERGY SPINNING ABOUT THE LARGE CLOSED LOW OVER SOUTHERN CANADA...WHICH WILL BE HARD TO TIME. WHILE AT THE SURFACE HIGH PRESSURE BUILDS IN. GUIDANCE IS IN AGREEMENT THAT THE REGION SHOULD BE BETWEEN SHORT WAVES TUESDAY SO EXPECTING A DRY DAY. HAVE POPS IN FORECAST FOR WEDNESDAY MAINLY TO THE WEST OF THE HUDSON RIVER VALLEY. TEMPERATURES WILL AVERAGE BELOW NORMAL FOR LATE JULY BY 5 TO 10 DEGREES. && .LONG TERM /THURSDAY THROUGH SUNDAY/... THE WEATHER WILL CONTINUE TO BE SOMEWHAT UNSETTLED DURING THE EXTENDED PERIOD. A LARGE CUT OFF UPPER LEVEL LOW WILL REMAIN SITUATED JUST TO OUR NORTHWEST OVER SOUTHERN CANADA TO START THE LONG TERM PERIOD. ALTHOUGH THIS UPPER LEVEL LOW WILL BE WEAKENING...IT WILL REMAIN CLOSE ENOUGH TO THE AREA TO ALLOW FOR CYCLONIC FLOW SHOWERS AND THUNDERSTORMS FOR THURSDAY AND FRIDAY...ESP DURING THE DIURNALLY FAVORED AFTERNOON AND EVENING HOURS. DAYTIME TEMPS WILL BE CLOSE TO NORMAL...WITH HIGHS IN THE UPPER 70S TO LOW 80S FOR VALLEY AREAS...AND MINS GENERALLY IN THE 50S TO LOW 60S. ALTHOUGH THE UPPER LEVEL LOW WILL FINALLY START TO LIFT OUT TO THE NORTHEAST...ANOTHER IMPULSE DIVING OUT OF THE SOUTH CENTRAL CANADA WILL MOVE TOWARDS THE GREAT LAKES AND NORTHEAST FOR THE WEEKEND. THIS WILL STRENGTHEN THE MEAN LONGWAVE TROUGH OVER THE EASTERN PORTION OF THE CONUS...WHILE A STRONG RIDGE REMAINS IN PLACE ACROSS THE WESTERN US. THE RESULT WILL BE A CONTINUED THREAT FOR SCATTERED SHOWERS AND THUNDERSTORMS OVER THE WEEKEND. AGAIN...THE HIGHEST COVERAGE/BEST CHANCE WILL BE DURING PEAK DAYTIME HEATING. TEMPS WILL CONTINUE TO RUN SIMILAR TO THE PAST FEW DAYS...WITH HIGHS RIGHT AROUND 80 AND LOWS IN THE UPPER 50S TO LOW 60S FOR VALLEY AREAS. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... CHANGEABLE FLYING CONDITIONS CAN BE EXPECTED AT ALL TERMINALS OVER THE NEXT 6-10 HOURS THANKS TO A STRONG STORM SYSTEM MOVING ACROSS THE AREA. THUNDERSTORMS HAVE DEVELOPED OVER CENTRAL NEW YORK...THE CATSKILLS...AND THE MID HUDSON VALLEY. THESE STORMS ARE MOVING TOWARDS THE NORTHEAST AT 20-30 MPH. WE HAVE INCLUDED THUNDER AT ALL THE TERMINALS FOR THIS AFTERNOON. THERE IS THE POTENTIAL FOR MVFR WITH ANY SHOWERS/THUNDERSHOWERS THAT HIT A TERMINAL SITE. A COLD FRONT SHOULD CLEAR THE AREA BETWEEN 00Z AND 02Z THIS EVENING. BEHIND THIS FRONT...WESTERLY WINDS WILL TRANSPORT COOLER AND LESS HUMID AIR INTO THE REGION. THIS WILL END THE THREAT FOR PRECIP...WITH SURFACE WINDS INCREASING TO AROUND 10-15 KTS WITH A FEW HIGHER GUSTS FOR THIS EVENING. SOME LINGERING CLOUDS WILL CONTINUE INTO THE FIRST HALF OF TONIGHT...BUT FLYING CONDITIONS SHOULD BE VFR FOR ALL SITES. BY LATE TONIGHT...CLOUDS SHOULD SCATTER OUT AND WINDS WILL START TO DIMINISH SO LOCALIZED FOG IS A THREAT AT THE TAF SITES. OUTLOOK... TUE NIGHT-WED: NO OPERATIONAL IMPACT. NO SIG WX. WED NIGHT: LOW OPERATIONAL IMPACT. SLIGHT CHANCE OF SHRA...TSRA. THU: MODERATE OPERATIONAL IMPACT. CHANCE OF SHRA...TSRA. THU NIGHT: NO OPERATIONAL IMPACT. NO SIG WX. FRI: MODERATE OPERATIONAL IMPACT. CHANCE OF SHRA...TSRA. FRI NIGHT: LOW OPERATIONAL IMPACT. SLIGHT CHANCE OF SHRA...TSRA. SAT: MODERATE OPERATIONAL IMPACT. CHANCE OF SHRA...TSRA. && .FIRE WEATHER... SHOWERS ARE LIKELY MUCH OF THE DAY WITH SCATTERED THUNDERSTORMS AS A A LOW PRESSURE SYSTEM OVER NEW YORK STATE CONTINUES TO MOVE EASTWARD. THE SYSTEM WILL MOVE OFF TO OUR NORTHEAST TONIGHT ALLOWING COOLER AIR TO FILTER INTO THE REGION. HIGH PRESSURE WILL BUILD IN AT THE SURFACE AS WE HEAD THROUGH MID WEEK...HOWEVER ALOFT DISTURBANCES WILL PASS OVER THE REGION. && .HYDROLOGY... SHOWERS ARE LIKELY MUCH OF THE DAY WITH SCATTERED THUNDERSTORMS AS A A LOW PRESSURE SYSTEM OVER NEW YORK STATE CONTINUES TO MOVE EASTWARD. HEAVY RAINFALL WILL OCCUR WITH SOME STORMS AS THE ATMOSPHERE IS VERY MOIST WITH DEW POINTS IN THE 60S. HAVE CONTINUED WITH ENHANCED WORDING IN FORECAST FOR HEAVY RAINFALL. THE HIGHEST RAINFALL TOTAL ARE EXPECTED MAINLY NORTH OF I-90 WITH AROUND AN INCH OF ADDITIONAL RAINFALL TODAY. LOCALLY HEAVY RAINFALL MAY RESULT IN SOME FLOODING OF LOW LYING AND POOR DRAINAGE AREAS. AREAS WHICH HAVE ALREADY RECEIVED A ROUND OF HEAVY RAINFALL WILL BE THE MOST VULNERABLE.
