AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE ALBANY NY 950 AM EST SAT DEC 11 2004 .SHORT TERM (TODAY)...PCPN NOT THAT WIDESPREAD AT THIS TIME AND SOME LOW-LYING AREAS IN THE ADIRONDACKS STILL APPEAR TO BE GETTING RAIN...SO WILL DROP THE WINTER WEATHER ADVISORIES FOR THE THREE NORTHERN ZONES AND ONLY MENTION ANOTHER INCH OF SNOW FOR THIS AFTERNOON. HAVE LOWERED POPS TO CHANCE LEVELS FOR THE SOUTHERN PART OF THE AREA BASED ON CURRENT RADAR/SFC OBSERVATION TRENDS...AND WILL KEEP LIKELY POPS ACROSS THE NORTHERN ZONES. .PREV DISCUSSION... SHORT TERM (TODAY THROUGH SUNDAY NIGHT)... AN UPPER LEVEL TROUGH OVER LAKE ERIE WAS TIED TO A SURFACE LOW PRESSURE OVER THE SOUTHERN CATSKILLS SHORTLY AFTER MIDNIGHT. RADAR COMPOSITES INDICATED THE HEAVIEST AND MOST WIDESPREAD PRECIPITATION WAS OVER CENTRAL NEW YORK. SOME BRIGHT BANDING APPEARS TO BE OCCURRING IN THE WESTERN ADIRONDACKS...AS SOME MELTING OF SNOW IN THE LOWER LEVELS OF THE ATMOSPHERE WAS LIKELY OCCURRING. THE MESOETA MODEL FORECAST SOUNDINGS FORECAST SOME COOLING TO OCCUR. WITH ABOUT HALF AN INCH OF LIQUID EQUIVALENT PRECIPITATION TONIGHT...THERE MAY BE SEVERAL INCHES OF SNOW IN THE ADIRONDACKS WHERE MAINLY SNOW OCCURS. THUS...THE WINTER WEATHER ADVISORY THAT WAS ISSUED EARLIER TO APPLY TO THE PERIOD 9 PM FRIDAY THROUGH 5 PM SATURDAY...WILL BE CONTINUED ON THE NEXT FORECAST. THE FORECAST SOUNDINGS INDICATED THAT THE PRECIPITATION IS LIKELY TO REMAIN SNOW IN THE ADIRONDACKS TODAY. THE LATEST GUIDANCE IS CONSISTENT WITH OUR PREVIOUS FORECAST INDICATING THE BEST CHANCE OF PRECIPITATION TODAY TO BE IN THE NORTHERN ZONES. WE WILL CONTINUE WITH CATEGORICAL PROBABILITIES NORTH...AND CHANCE VALUES IN THE SOUTHERN ZONES. THE LATEST MAXIMUM TEMPERATURE GUIDANCE IS LOBBYING FOR VALUES A FEW DEGREES HIGHER THAN OUR PREVIOUS FORECAST IN THE ADIRONDACKS...SO WELL TWEAK THE HIGH TEMPERATURE UP A FEW DEGREES IN THIS AREA. LITTLE CHANGE IS INDICATED IN OTHER LOCATIONS. LOTS OF CLOUDS INDICATED FOR TODAY ON THE LATEST GUIDANCE. THE SURFACE WIND WILL BE LIGHT THIS MORNING...AND SLOWLY SWITCH TO THE WEST THIS AFTERNOON AS THE LOW PRESSURE MOVES TO THE NORTH. EASTERN NEW YORK AND WESTERN NEW ENGLAND WILL BE IN A SNOW SHOWER REGIME MOST OF TONIGHT...WITH A WESTERLY LOW LEVEL WIND FLOW OF COLDER AIR. THE LATEST GUIDANCE INDICATES THAT THE MINIMUM TEMPERATURE WILL BE NEAR FREEZING IN THE LOWER HUDSON VALLEY AND NEAR 20 IN THE ADIRONDACKS. THE AVIATION VALUES OF MINIMUM TEMPERATURE WERE SLIGHTLY HIGHER THAN THE ETA AND NESTED GRID FORECAST. THE ETA AND NESTED GRID WERE QUITE SIMILAR TO OUR PREVIOUS FORECAST...AND WE WILL FAVOR THEM FOR CONSISTENCY SAKE. WELL BE STAYING WITH LIKELY PROBABILITY IN THE WESTERN ADIRONDACKS...AND FORECASTING AN INCH OR LESS OF SNOWFALL THERE. ON SUNDAY...AN UPPER LEVEL SHORT WAVE WILL BECOME CLOSED OFF OVER THE CENTRAL GREAT LAKES BY EVENING. AN ASSOCIATED SURFACE LOW PRESSURE WILL BE IN THE VICINITY OF LAKE HURON SUNDAY EVENING. THE SURFACE WIND WILL BACK AROUND TO THE SOUTH LATE IN THE DAY AND SOME SNOW IS LIKELY TO OCCUR AROUND SUNSET IN THE WESTERN ZONES. THE AVIATION GUIDANCE AGREES WITH OUR PREVIOUS FORECAST IN THIS REGARDS. THE ETA AND NESTED GRID INDICATE DRY WEATHER ACROSS THE ENTIRE COUNTY WARNING AREA. THE CANADIAN REGIONAL MODEL FORECASTS SNOW RIGHT UP TO THE CAPITAL DISTRICT BY HOUR ZERO UNIVERSAL COORDINATION TIME SUNDAY...WHICH APPEARS TO BE MORE IN AGREEMENT WITH THE AVIATION FORECAST. SO...WELL STICK WITH OUR PREVIOUS FORECAST...SINCE THERE IS NOT A CONSENSUS REGARDING THE OUTCOME. THE GUIDANCE FROM THE NESTED GRID...ETA AND AVIATION INDICATE THAT THE HIGH TEMPERATURE MAY BE A TAD LOWER THAN OUR PREVIOUS FORECAST IN THE ADIRONDACKS. IN THE HUDSON VALLEY...THE AVIATION AND ETA HAVE HIGHER VALUES...AND THE NESTED GRID LOWER. WELL GO FOR HIGHS VERY SIMILAR TO OUR PREVIOUS FORECAST. THE FORECAST SOUNDINGS SUGGEST PARTLY CLOUDY CONDITIONS IN THE HUDSON VALLEY...WITH LOTS OF CLOUDS TO THE NORTH AND WEST. THIS AGREES WELL WITH CLOUD GUIDANCE. THE CYCLONE PASSES ACROSS NORTHERN NEW YORK INTO NORTHERN NEW ENGLAND AND THE CANADIAN MARITIMES FROM SUNDAY EVENING THROUGH MONDAY EVENING. THE LATEST ETA AND NESTED GRID GUIDANCE HAVE ONLY CHANCE PROBABILITIES IN THE EAST AND SOUTH PORTION OF THE COUNTY WARNING AREA. THE AVIATION HAS HIGHER VALUES ACROSS THE COUNTY WARNING AREA. BASED ON THE LATEST CANADIAN ENSEMBLE FORECAST WHICH HAS LIKELY PROBABILITY ACROSS THE REGION...WELL GO CLOSER TO THE AVIATION FORECAST. THE SURFACE WIND WILL VEER TO THE WEST LATE SUNDAY NIGHT. THE LATEST MINIMUM TEMPERATURE GUIDANCE SUGGESTS MAKING LITTLE CHANGE TO OUR PREVIOUS FORECAST. THUS...WELL HAVE VALUES RANGING FROM THE LOWER 20S IN THE ADIRONDACKS TO THE LOWER 30S IN THE LOWER HUDSON VALLEY. && .LONG TERM (MONDAY THROUGH FRIDAY)... LITTLE CHANGE FOR MONDAY. THE REGION WILL RETURN TO A SNOW SHOWER REGIME WITH A CHILLY WESTERLY SURFACE WIND MONDAY. LIKELY PROBABILITY VALUES IN THE WEST...AND CHANCE IN THE HUDSON VALLEY AND TO THE EAST. THE AVIATION HIGH TEMPERATURES ARE CONSIDERABLY LOWER THAN THE ETA VALUES FOR MONDAY. WELL STICK WITH THE AVIATION AS IT AGREES BEST WITH OUR PREVIOUS FORECAST. THE PROBABILITY WILL BE A BIT LOWER MONDAY NIGHT...BUT STILL A CHANCE OF SNOW SHOWERS IN THE WEST. THE MINIMUM TEMPERATURE WILL BE BUMPED UPWARD SLIGHTLY TO CONFORM TO THE LATEST GUIDANCE. A COLD DAY TUESDAY AS THE 1000 TO 500 MILLIBAR LAYER THICKNESS IS FORECAST TO BE AROUND 5160 METERS. THE LATEST MAXIMUM TEMPERATURE GUIDANCE IS CLOSE TO OUR PREVIOUS FORECAST. A NORTHWEST WIND AND AN UPPER LEVEL TROF OVER THE REGION SPELLS CHANCE SNOW SHOWERS IN THE FAVORED TERRAIN OF THE WESTERN PART OF THE COUNTY WARNING AREA. DRY WEATHER CONTINUES TO LOOK LIKELY FOR MIDWEEK...BUT QUITE COLD...WITH BELOW FREEZING TEMPERATURES EVERYWHERE FOR WEDNESDAY. THE LATEST GUIDANCE FROM THE CANADIAN ENSEMBLE PRODUCT LOOKS TO BE IN REASONABLE AGREEMENT WITH THE AVIATION FORECAST DURING THE LATTER PART OF THE WEEK. LITTLE CHANGE WILL BE MADE TO THIS PORTION OF THE FORECAST. A MINOR WAVE PASSING NORTH OF THE REGION EARLY FRIDAY MAY BRING A COLD FRONT THRU. BUT WHAT WE ARE DEALING WITH HERE IS BASICALLY A MEAN WESTERLY LOW LEVEL FLOW OF COLD AIR ACROSS THE EASTERN GREAT LAKES WHICH SHOULD RESULT IN SNOW SHOWERS IN AT LEAST THE FAVORED TERRAIN OF THE COUNTY WARNING AREA. DAY 8 (SATURDAY) WILL BE CONSTRUCTED USING THE CANADIAN ENSEMBLE PRODUCT AND THE LATEST AVIATION GUIDANCE. EARLY INDICATIONS ARE THE CONTINUED CHANCE OF SNOW SHOWERS IN THE WESTERN PORTION OF THE COUNTY WARNING AREA FOR SATURDAY. && .AVIATION...

CONDITIONS WILL BE MOST FAVORABLE IN THE MID HUDSON REGION OF NEW YORK AND NORTHWEST CONNECTICUT AND WORST OVER THE ADIRONDACKS. CONDITIONS WILL SLOWLY IMPROVE LATE THIS AFTERNOON TO MVFR WITH CEILINGS AROUND 3500 FEET...AND SOME VFR CONDITIONS WILL PROBABLY OCCUR ON SUNDAY BEFORE THE NEXT SYSTEM CAUSES THEM TO DETERIORATE WSUNDAY NIGHT. && .HYDROLOGY... RIVER STATEMENT WAS ISSUED AROUND 215 AM TO HANDLE RISING LEVELS OF THE MOHAWK RIVER AND SCHOHARIE CREEK FROM THE RAIN. LAKES DELTA AND HINCKLEY SPILLING WHICH IS OF SOME CONCERN ALSO. THE GROUND IS WET. UTICA FORECAST TO GET WITHIN INCHES OF FLOOD LATER THIS AFTERNOON. && .ALY WATCHES/WARNINGS/ADVISORIES... CT...NONE. MA...NONE. NY...NONE. &&
