NWS Albany, NY wrote its last area forecast discussion before the first event at Sep 18, 12:50 AM EST, 7 hours 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 150 AM EDT SAT SEP 18 2004 .SYNOPSIS... LOW PRESSURE WILL MOVE ACROSS THE NORTHERN MID ATLANTIC REGION AND OUT TO SEA LATER TODAY. HEAVY RAINFALL IS ASSOCIATED WITH THIS LOW ACROSS THE SOUTHERN TWO THIRDS OF THE COUNTY WARNING AREA. DRIER AIR WILL MOVE IN FROM THE NORTH AND WEST TODAY. BY TONIGHT...THE COUNTY WARNING AREA WILL BE IN A DRY AIR MASS. AN ANTICYCLONE WILL BUILD FROM NORTH OF THE GREAT LAKES EARLY TODAY TO BE CENTERED OVER NEW YORK AND NEW ENGLAND MONDAY. A TIGHT PRESSURE GRADIENT WILL BE ACROSS EASTERN NEW YORK AND WESTERN NEW ENGLAND SUNDAY...AND WILL QUICKLY RELAX SUNDAY NIGHT. THE ANTICYCLONE WILL SINK SOUTHWARD ACROSS THE MID ATLANTIC REGION TUESDAY AND WEDNESDAY. A WEAK COOL FRONT WILL MOVE TO NEAR THE ST LAWRENCE VALLEY WEDNESDAY EVENING AND WILL WASH OUT WEDNESDAY NIGHT. A LARGE ANTICYCLONE WILL IMPACT THE AREA FROM THE GREAT LAKES AND INTO THE NORTHEASTERN UNITED STATES DURING THE LATTER PORTION OF THE WEEK. && .SHORT TERM (TODAY THROUGH SUNDAY NIGHT)... ALL THE MODELS ARE INDICATING A HEAVY DUMP OF RAINFALL IN THE SOUTHEAST HALF OF THE COUNTY WARNING AREA THROUGH THIS MORNING. BASED ON THE FACT THAT SIGNIFICANT RAINFALL IS FORECAST TO OCCUR LATE THIS MORNING INTO EARLY THIS AFTERNOON IN THE SOUTHEAST...AND FACTORING IN THE USUAL LAG BETWEEN RAINFALL AND THE OCCURRENCE OF FLOODING...WE MAY EXTEND THE FLOOD WATCH UNTIL AT LEAST 2 PM...PERHAPS UNTIL 4 PM. AN EXTENSION UNTIL 430 PM...MIGHT WORK BEST LOGISTICALLY SPEAKING AS THE LATE AFTERNOON FORECAST PACKAGE WILL BE OUT AROUND THAT TIME. WE WILL BOOST THE PROBABILITY OF PRECIPITATION FORECAST TO HIGHER VALUES THAN THE PREVIOUS FORECAST ACROSS THE SOUTHEASTERN PORTION OF THE COUNTY WARNING AREA FOR TODAY. DOING THIS WOULD BE IN GOOD AGREEMENT WITH THE LATEST MODEL FORECAST GUIDANCE. WE WILL LOWER THE MAXIMUM TEMPERATURE JUST A TAD BASED ON THE LATEST GUIDANCE FROM NESTED GRID...ETA AND AVIATION MODEL FORECASTS. RAPID CLEARING IS INDICATED TONIGHT. THE TEMPERATURE WILL LIKELY FALL TO THE LOWER AND MID 30S IN THE SOUTHERN ADIRONDACK AREA. THESE VALUES REQUIRE THAT A FROST ADVISORY BE ISSUED. HOWEVER...THE GUIDANCE TEMPERATURES MAY BE TOO LOW AS A TIGHT GRADIENT IS FORECAST ACROSS THIS REGION...AND IT IS REASONABLE TO BELIEVE THERE WILL BE ENOUGH OF A NORTHERLY BREEZE TO KEEP THE TEMPERATURES ABOVE FROST LEVELS. ON SUNDAY...A BRISK NORTH BREEZE AND PLENTY OF SUNSHINE IS EXPECTED FOR THE BULK OF THE DAY. THE MAXIMUM TEMPERATURES WILL BE LOWERED A TAD FROM WHAT WAS FORECAST IN THE PREVIOUS GUIDANCE. SUNDAY NIGHT WILL FEATURE A CLEAR SKY...LIGHTER WIND...AND THE POTENTIAL FOR FROST IN AT LEAST THE REGION FROM THE SOUTHERN ADIRONDACKS INTO SOUTHERN VERMONT. IT IS STILL TOO EARLY TO ISSUE A HEADLINE ON ANY FROST...BUT IT SHOULD BE MENTIONED IN THE BODY OF THE ZONE FORECAST. ALL THE LATEST MODEL GUIDANCE SUGGESTS CUTTING AT LEAST A FEW DEGREES FROM THE PREVIOUSLY FORECAST MINIMUM TEMPERATURES FOR SUNDAY NIGHT. THE GUIDANCE POINTS TO TEMPERATURES LOW ENOUGH FOR A FREEZE WARNING IN A PORTION OF THE NORTHERN HERKIMER AND HAMILTON COUNTIES. && .LONG TERM (MONDAY THROUGH FRIDAY)... LATEST GUIDANCE FROM THE CANADIAN REGIONAL AND AVIATION MODELS...SUGGESTS DRY WEATHER THIS PERIOD. THE PREVIOUS FORECAST HAD A 20 PERCENT PROBABILITY FOR FRIDAY. WE MAY LOWER THE PROBABILITY && .AVIATION...WIDESPREAD MVFR AND IFR CONDITIONS THROUGH MID MORNING IN HEAVY RAINFALL. CONDITIONS IMPROVING TO VFR FROM NORTH TO SOUTH THROUGH THE AFTERNOON. VFR CONDITIONS TONIGHT. NORTHEAST WIND 5 TO 15 KNOTS TODAY...NORTH WIND TONIGHT MAINLY 10 KNOTS OR LESS. && .HYDROLOGY... HEAVY RAINFALL HAS OCCURRED ACROSS THE CATSKILLS EAST INTO THE BERKSHIRES. OVER 3 INCHES OF RAINFALL HAS BEEN REPORTED IN SOME LOCATIONS. FLASH FLOOD WARNINGS HAVE BEEN ISSUED FOR A PORTION OF THE CATSKILL REGION AND THE CAPITAL DISTRICT EARLY THIS MORNING. OTHER FLOOD WARNINGS MAY BE ISSUED DURING THE COURSE OF THE MORNING. A FLOOD WATCH IS IN EFFECT THROUGH LATE THIS MORNING. LATER THIS MORNING...THIS FLOOD WATCH MAY HAVE TO BE EXTENDED INTO THIS AFTERNOON. A LONG PERIOD OF DRY WEATHER IS LIKELY AFTER TODAY WHICH WILL ALLOW RIVERS TO RECOVER FROM THE HEAVY RAINFALL. && .ALY WATCHES/WARNINGS/ADVISORIES... CT...FLOOD WATCH UNTIL 10 AM SAT...CTZ001-013.
