NWS Albany, NY wrote its last area forecast discussion before the first event at May 25, 12:24 AM EST, 6 hours 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 124 AM EDT TUE MAY 25 2004 DISCUSSION... AFTER CHECKING THE LATEST MODEL FORECASTS FROM THE AVIATION...ETA... AND THE TWO CANADIAN MODELS (REGIONAL/GLOBAL)...IT IS BELIEVED THAT THE BEST CHANCE OF IMPROVING THE GRID/ZONE FORECAST FROM MONDAY IS TO INTRODUCE A CHANCE OF PRECIPITATION INTO THE FRIDAY FORECAST. A MINOR UPPER-LEVEL SHORT WAVE AND CYCLONE MAY BRING SOME SHOWERS AND THUNDERSTORMS ON FRIDAY. THE CANADIAN GLOBAL AND AVIATION MODELS FORECAST SIGNIFICANT PRECIPITATION FRIDAY...A PROJECTION OF THE ETA FORECAST BEYOND ITS 84-HOUR LIMIT SUGGESTS PRECIPITATION FOR FRIDAY FROM THAT MODEL AS WELL. OTHER THAN FRIDAY...WELL LIKELY BE STICKING FAIRLY CLOSE TO THE PREVIOUS FORECAST. IT LOOKS LIKE THE RELATIVELY COOL AIR OVER MUCH OF NEW ENGLAND WILL HOLD IN PLACE FOR SEVERAL MORE DAYS AS AN ANTICYCLONE OVER THE CANADIAN MARITIMES AND WESTERN ATLANTIC MOVE VERY LITTLE. THE STATIONARY FRONT THAT WAS DRAPED ACROSS THE SOUTHERN PORTION OF NEW YORK AND NEW ENGLAND OVER THE WEEKEND WAS SAGGING SOUTHWARD THIS MORNING...AND DRIER AIR WAS TAKING HOLD. THE PRECIPITABLE WATER AMOUNTS FOR TODAY IN EASTERN NEW YORK AND WESTERN NEW ENGLAND ARE FORECAST TO BE 20 MILLIMETERS (8 TENTHS OF AN INCH) OR LESS IN THE BULK OF THE COUNTY WARNING AREA. THATS ABOUT 3 QUARTERS OF AN INCH LESS THAN AMOUNT THAT WAS OVER THE REGION DURING THE WEEKEND AND ON MONDAY. THE DRIER AIR WILL BE AROUND ONLY A SHORT WHILE...HOWEVER. A WEAK CYCLONE OVER THE GREAT LAKES TODAY WILL MOVE NORTH AND EAST. THE CIRCULATION ACROSS EASTERN NEW YORK WILL QUICKLY DEVELOP A SOUTHERLY COMPONENT...AND AIR OF RELATIVELY HIGH WATER CONTENT WILL RETURN TO THE REGION. DYNAMICS AND INSTABILITY NEEDED TO PRECIPITATE THIS WATER ARE LIKELY TO BE MOST FAVORABLE IN THE SOUTHEASTERN PORTION OF THE COUNTY WARNING AREA LATE TONIGHT THROUGH MID AFTERNOON WEDNESDAY. FROM THE CAPITAL DISTRICT SOUTHWARD...THE AVIATION MODEL FORECASTS UP TO AN INCH AND A HALF OF RAINFALL DURING THIS PERIOD. THE ETA FORECASTS MUCH LESS...GENERALLY BETWEEN A TENTH AND A THIRD OF AN INCH...WHILE THE CANADIAN REGIONAL CHECKS IN WITH BETWEEN HALF AN INCH AND AN INCH. THE GLOBAL HAS A LITTLE LESS THAN ITS REGIONAL KIN. THE CANADIAN REGIONAL MODEL IS FORECASTING A QUITE INTENSE AND COMPACT UPPER-LEVEL VORTICITY MAXIMUM TO RIDE JUST SOUTH OF NEW YORK LATE TONIGHT AND EARLY WEDNESDAY. IT HAS THE APPEARANCE OF CONVECTIVE FEEDBACK CONTAMINATION. MODEL CONSENSUS IS FOR A MUCH LESS VIGOROUS UPPER-LEVEL FEATURE. THE ETA BARELY INDICATES A VORTICITY MAXIMUM. BUT IT IS CLEAR...THAT ALL THE MODELS ARE FORECASTING THE BEST DYNAMICS ACROSS THE SOUTHERN PORTION OF OUR COUNTY WARNING AREA WITH THE NEXT PRECIPITATION EVENT. WHEN WILL IT ARRIVE? THERE ARE SOME DIFFERENCES FROM MODEL TO MODEL. THE AVIATION FORECASTS VERY LITTLE PRECIPITATION TONIGHT...WHILE THE ETA BRINGS NEARLY HALF AN INCH TO THE LOWER HUDSON VALLEY LATE TONIGHT. THE CANADIAN REGIONAL APPEARS TO HOLD OFF UNTIL AFTER MIDNIGHT...AND PREFERS TO BRING THE MORE WIDESPREAD PRECIPITATION TO THE COUNTY WARNING AREA WEDNESDAY. THE FORECAST THAT WAS ISSUED MONDAY LOOKS LIKE A REASONABLE COMPROMISE OF THE LATEST MODEL GUIDANCE...AND WE DONT EXPECT TO DEVIATE MUCH. THE AVIATION FORECASTS THE SYSTEM TO LEAVE MORE QUICKLY THAN THE OTHER MODELS. AS A RESULT...IT IS FORECASTING DRY WEATHER WEDNESDAY NIGHT. THE CANADIAN REGIONAL AND ETA LINGER SOME LIGHT PRECIPITATION INTO WEDNESDAY EVENING. THE GRID/ZONE FORECAST FROM MONDAY HAD A CHANCE FOR THE ENTIRETY OF WEDNESDAY NIGHT...WELL CUT IT BACK TO ONLY THE EVENING HOURS. ALL MODELS ARE FORECASTING DRY WEATHER ON THURSDAY...AND THIS AGREES WITH WHAT WE ISSUED MONDAY. THEREFORE...NO CHANGES. THE CANADIAN GLOBAL BRINGS PRECIPITATION INTO THE COUNTY WARNING AREA MORE QUICKLY THAN THE AVIATION OR ETA MODELS LATE IN THE WEEK. THE CANADIAN HAS SOME RAINFALL FORECAST LATE FRIDAY NIGHT. THIS IS AT ODDS WITH THE CANADIAN ENSEMBLE FORECASTS FROM 24 HOURS AGO. THUS...WELL IGNORE IT AND KEEP THE FORECAST DRY THROUGH THURSDAY NIGHT PER ETA AND AVIATION FORECASTS. THEN AS MENTIONED...WELL INTRODUCE A CHANCE OF SHOWERS AND THUNDERSTORMS FRIDAY. UNLESS SURROUNDING OFFICES MAKE CHANGES TO THEIR WEEKEND FORECASTS WELL HOLD THE LINE. WE HAD A SMALL CHANCE OF SHOWERS SATURDAY AND A DRY FORECAST FOR SUNDAY. HOWEVER...THIS IS AT ODDS WITH THE LATEST FORECASTS OF THE CANADIAN GLOBAL AND AVIATION MODELS WHICH ARE DRY FOR SATURDAY AND WET SUNDAY. BUT...ITS FAR ENOUGH INTO THE FUTURE TO BELIEVE THAT AN ENSEMBLE APPROACH MAY BE BEST. AND ENSEMBLE FORECASTS WONT BE AVAILABLE UNTIL LATER THIS MORNING. WELL VIEW THEM BEFORE TAKING ON THE DAY 8 GRIDS AROUND 5 AM. THE LATEST TEMPERATURE GUIDANCE SUGGESTS THAT WE SHOULD MAKE LITTLE CHANGE TO THE MAXIMUM AND MINIMUM TEMPERATURES TODAY AND TONIGHT. HOWEVER...OUR FORECAST FOR WEDNESDAY MAY NOT BE QUITE COOL ENOUGH...AT LEAST IF ONE BELIEVES THE LATEST ETA FORECASTS. HOWEVER...WITH OUR FORECAST OF WIDESPREAD READINGS IN THE 60S FOR WEDNESDAY...IT DOES NOT SEEM UNREASONABLE TO BELIEVE THAT THIS WILL BE CLOSE TO WHAT VERIFIES BECAUSE OF THE TIME OF THE YEAR. THE READINGS IN THE MID 50S THAT ARE FORECAST BY THE ETA FOR WEDNESDAY IN SOUTHERN VERMONT LOOK A LITTLE TOO EXTREME. THE AVIATION GUIDANCE IS 10 DEGREES HIGHER THERE. .HYDROLOGY...ON MONDAY...RAINFALL OF 6 TO 7 INCHES (RADAR ESTIMATES) OCCURRED IN SOME LOCATIONS ACROSS THE NORTHERN PORTION OF THE COUNTY WARNING AREA (ESPECIALLY IN THE SOUTHERN ADIRONDACKS AND EXTREME SOUTHERN WASHINGTON COUNTY). ONE TO TWO INCH AMOUNTS WERE WIDESPREAD ACROSS THE SOUTHERN PORTION OF THE COUNTY WARNING AREA. TODAY WILL BE DRY...BUT THERE IS A HIGH PROBABILITY THAT SOME RAINFALL WILL RETURN TONIGHT (ESPECIALLY AFTER MIDNIGHT IN THE SOUTHEAST). SHOWERS AND THUNDERSTORMS ARE LIKELY FOR A GOOD PORTION OF WEDNESDAY MORNING AND EARLY WEDNESDAY AFTERNOON. RAINFALL FORECASTS VARY FROM MODEL TO MODEL...WITH THE AVIATION THE MOST THREATENING...FORECASTING AN INCH TO AN INCH AND A HALF WEDNESDAY. MAINLY DRY WEATHER IS FORECAST WEDNESDAY NIGHT...AND THURSDAY IS LIKELY TO BE DRY. FLOODING IS OCCURRING ON PORTIONS OF THE MOHAWK RIVER AND ITS DRAINAGES. THE FLOODING SHOULD BEGIN TO EASE UP TODAY AND MAY END ALTOGETHER THIS EVENING. THE MAIN THREAT OF FLOODING WEDNESDAY APPEARS MOST LIKELY TO BE FROM THE CAPITAL DISTRICT SOUTHWARD LATE TONIGHT AND WEDNESDAY...AND IT DOESNT SEEM VERY HIGH NOW. BUT IT BEARS WATCHING AS CONVECTIVE PRECIPITATION AMOUNTS CAN OFTEN BE SURPRISINGLY LARGE. AVIATION...CONDITIONS WILL BE QUITE VARIABLE BEFORE DAYBREAK DUE TO THE PRESENCE OF AREAS OF STRATUS AND FOG. SOME LOCATIONS WILL BE VFR...WHILE OTHER WILL BE LIFR. AFTER DAYBREAK...VFR CONDITIONS WILL BECOME WIDESPREAD BY MID MORNING AND CONTINUE THROUGH MUCH OF TONIGHT. CONDITIONS MAY BECOME OCCASIONALLY MVFR IN SHOWERS AND POSSIBLE THUNDERSTORMS LATE TONIGHT...ESPECIALLY FROM THE LOWER CATSKILLS INTO THE MID HUDSON VALLEY AND SOUTHERN NEW ENGLAND. .ALY...OTHER THAN SOME FLOOD WARNING FOR TODAY ON PORTIONS OF THE MOHAWK RIVER...NONE HEMMERICH
HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE ALBANY NY 508 AM EDT TUE MAY 25 2004 CTZ001-013-MAZ001-025-NYZ032-033-038>043-047>054-058>061-063>066- 082>084-VTZ013>015-261100- THIS HAZARDOUS WEATHER OUTLOOK IS FOR EASTERN NEW YORK AND WESTERN NEW ENGLAND. .DAY ONE...TODAY NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME. BUT FORECASTERS ARE KEEPING A WARY EYE ON THE WEATHER FOR EARLY WEDNESDAY MORNING, SHORTLY BEFORE DAYBREAK. WE DONT THINK SEVERE THUNDERSTORMS WILL OCCUR AT THAT TIME...BUT IF THEY DO THE MOST LIKELY THREAT WILL BE FROM HAIL. .DAYS TWO THOUGH SEVEN... THERE MAY BE SOME POTENTIAL FOR SEVERE WEATHER ON WEDNESDAY, BUT IT IS NOT A LARGE RISK BY ANY MEANS. IT IS THE CONTINUATION OF THE EVENT FROM LATE TUESDAY NIGHT. NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME BEYOND WEDNESDAY. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT ANTICIPATED.
