NWS Albany, NY wrote its last area forecast discussion before the first event at Jun 30, 12:35 AM EST, 2 hours 55 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTION NATIONAL WEATHER SERVICE ALBANY NY 135 AM EDT MON JUN 30 2003 .DISCUSSION... THE COOL FRONT WAS KIND OF HARD TO LOCATE ON THE SURFACE REPORTS EARLY THIS MORNING. A BAND OF THUNDERSTORMS WAS ORGANIZING IN WEST CENTRAL NEW YORK SHORTLY AFTER MIDNIGHT. PERHAPS THAT WAS THE LOCATION OF THE FRONT. FROM THE THICKNESS AND MOISTURE PARAMETERS OF THE LATEST RUN OF THE FORECAST MODELS, IT APPEARED THAT THE FRONT WOULD BY LYING NEAR KPOU AT HOUR 12 UNIVERSAL COORDINATION TIME TODAY. THE ETA AND CANADIAN REGIONAL MODELS SUGGESTED THAT THE CONVECTIVE AVAILABLE POTENTIAL ENERGY WOULD BE SLIGHTLY OVER 1000 JOULES PER KILOGRAM IN THAT AREA THIS MORNING. DRIER AIR IS FORECAST TO ADVECT INTO SOUTHEASTERN NEW YORK BY EARLY THIS AFTERNOON AS THE FRONT CONTINUES TO SAG SOUTHWARD INTO THE NORTHERN PORTION OF THE MID ATLANTIC REGION LATER TODAY. THE NEXT RELEASE OF THE ZONE FORECAST WILL LIKELY HAVE TO HAVE A MENTION OF SOME PRECIPITATION THIS MORNING, ALMOST CERTAINLY BEFORE DAYBREAK AND PERHAPS LATER THIS MORNING AS WELL, ACROSS THE LOWER HUDSON VALLEY INTO WESTERN CONNECTICUT AND THE SOUTHERN BERKSHIRES. THE ETA MODEL INDICATES FAVORABLE MOISTURE FLUX DIVERGENCE WILL OCCUR IN THAT AREA THIS MORNING, AND THE MESOSCALE ETA FORECAST SOUNDINGS NEAR POUGHKEEPSIE THIS MORNING WERE INDICATIVE OF POSSIBLE DEEP CONVECTION TOPPING AT AROUND 40 THOUSAND FEET. THE SOUNDINGS INDICATE THAT THE AIR MASS BECOMES MORE STABLE THERE THIS AFTERNOON, AND THE MOISTURE FLUX DIVERGENCE BECOME UNFAVORABLE FOR CONVECTION. THE NESTED GRID, ETA, AND CANADIAN REGIONAL MODELS WERE ALL INDICATING DRY WEATHER ACROSS MOST, IF NOT ALL OF THE COUNTY WARNING AREA AFTER HOUR 12 UNIVERSAL COORDINATION TIME. THE AVIATION FORECAST MEASURABLE PRECIPITATION IN THE SOUTHEASTERN PORTION OF THE COUNTY WARNING AREA INTO THIS AFTERNOON, YET ITS CLIMATOLOGICAL- STATISTICAL FORECAST PROBABILITIES OF PRECIPITATION WERE WELL BELOW THE THRESHOLD FOR MENTIONING PRECIPITATION. THE NESTED GRID GENERALLY HAD THE HIGHEST PROBABILITIES, AND THESE WERE BARELY 30 PERCENT IN THE MOST FAVORABLE SOUTHEASTERN LOCATIONS, IF THAT. WITH THE FRONT MOVING SOUTH OF THE AREA AND THE AIR DRYING BY THE TIME THE ATMOSPHERE HEATS UP ENOUGH TO GENERATE CONVECTION, IT IS BELIEVED THAT SHOWERS AND THUNDERSTORMS ARE NOT LIKELY TO OCCUR TODAY, EVEN IN THE SOUTHEAST. HOWEVER, WITH THE AIR MASS AS UNSTABLE AS IT IS INDICATED TO BE BY THE FORECAST MODELS, IT SEEMS PRUDENT TO MENTION AT LEAST A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS IN THE SOUTHEASTERN ZONES FOR TODAY. MAXIMUM TEMPERATURES ARE FORECAST TO BE IN THE LOW AND MID 80S IN THE HUDSON VALLEY, FALLING OFF TO THE MID 70S IN THE ADIRONDACKS AND OTHER MOUNTAIN LOCATIONS. A RATHER LIGHT WEST WIND THIS MORNING SHOULD BECOME WEST-NORTHWEST AT 10 TO 15 MILES AN HOUR THIS AFTERNOON. DRIER AIR WILL TAKE HOLD BY THIS EVENING, AND TONIGHT IS EXPECTED TO BECOME CLEAR. LOW TEMPERATURES WILL BE IN THE 50S, AND THE WIND WILL BECOME LIGHT AND VARIABLE. A SHORT WAVE TROUGH MOVING SOUTHEASTWARD ACROSS CENTRAL AND EASTERN CANADA LATER TODAY INTO TUESDAY, WILL INDUCE A COLD FRONT TO DIP SOUTHWARD TO THE VICINITY OF THE NORTHERN BORDER OF NEW YORK AND VERMONT TUESDAY MORNING. THIS IS FORECAST TO BE A DRY FRONT BY THE TIME IT REACHES THE NORTHEASTERN UNITED STATES, AND LITTLE, IF ANY CLOUDINESS IS EXPECTED TO IMPACT ALBANYS COUNTY WARNING AREA TUESDAY. MAXIMUM TEMPERATURES SHOULD BE SIMILAR TO TODAYS VALUES. THE LATEST RUN OF THE CANADIAN GLOBAL MODEL INDICATED THAT THIS FORECAST TOOL WAS TRYING TO MAKE MORE OF THE SYSTEM IN THE SOUTHEAST THAN IT HAD BEEN DOING ON PREVIOUS RUNS. IT WAS DEVELOPING A CYCLONE IN THE SOUTHEASTERN UNITED STATES AND WAS BRINGING SOME PRECIPITATION ACROSS THE SOUTHERN BORDER OF NEW YORK WEDNESDAY. THE LATEST RUN OF THE AVIATION MODEL WAS SIMILAR, BUT HAD LIGHTER PRECIPITATION, AND LESS DEVELOPMENT. THE CANADIAN MODEL WAS ESSENTIALLY DRY FOR SEVERAL DAYS THEREAFTER, WHILE THE AVIATION, AS WAS THE CASE ON THE HOUR 12 UNIVERSAL COORDINATION TIME RUN, WAS DEVELOPING SOME CONVECTIVE PRECIPITATION IN SOUTHEASTERN NEW YORK THURSDAY AFTERNOON. THIS WAS ASSOCIATED WITH INCREASING INSTABILITY ALONG THE LEADING EDGE OF A LITTLE COOLER AIR THAT IS FORECAST TO MOVE INTO NEW YORK WEDNESDAY NIGHT AND EARLY THURSDAY. ON INDEPENDENCE DAY THE AVIATION MODEL CONTINUED TO SUGGEST THAT THERE COULD BE SCATTERED CONVECTION. SUNDAYS ZONE FORECASTS DID NOT INDICATE ANY PRECIPITATION LATER IN THE WEEK, AND FOR NOW WELL CONTINUE TO RIDE A DRY FORECAST THROUGH THE END OF THE WEEK. .HYDROLOGY...ANY RAINFALL FROM SHOWERS AND THUNDERSTORMS THIS MORNING IS EXPECTED TO RESULT IN BASIN-WIDE AVERAGES BELOW FLOOD GUIDANCE. THERE SHOULD BE SEVERAL DRY DAYS WELL INTO THE COMING WEEK. NO FLOODING IS ANTICIPATED FOR THE FORESEEABLE FUTURE. .ALY...NONE. HEMMERICH
