AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 415 PM EDT TUE AUG 12 2003 WORKZONES AVAILABLE. SORRY FOR BEING A BIT LATE ON THINGS...AND NOT RESPONDING ON 12 PLANET. LOTS OF TECHNICAL ISSUES GOING ON IN THIS OFFICE TODAY...PLUS MORE HEAVY RAINERS GOING ON. .DISC...FINALLY...THERE IS END TO THIS REALLY NASTY WEATHER PATTERN HE ETERNAL UPPER AIR TROUGH IS FINALLY BEGINNING TO BREAK DOWN...BUT NOT WITHOUT ONE MORE EVENING OF HEAVY RAINERS. TWO TROUGHS ARE THE FOCUSING MECHANISMS FOR THE DEVELOPMENT...ONE ACROSS OUR SOUTHERN ZONES...AND ANOTHER JUST NORTH OF OUR REGION. THE NORTHERN ONE...IS THE LEADING OF THE LONG AWAITED DRIER AIR. TDS ACROSS QUEBEC DROPPED MARKEDLY...AS LOW AS THE 40S IT WILL TAKE AWHILE BEFORE WE GET ANYWHERE NEAR THAT DRY. WE EXPECT THE ACTIVITY TO PEAK AROUND SUNSET...THEN SLOWLY DIE OFF THEREAFTER. WILL SPLIT THE TONIGHT PERIOD INTO TWO PERIODS...AND CONFINED THE ACTIVITY TO THE EVENING. (MAVS AND FWCS GIVE MOST OF OUR AREA > 30 POP THRESHOLD FOR THE ENTIRE EVENING PERIOD). WE WILL LEAVE THE FLOOD WATCH UP AS IS...AND LET IT EXPIRE AT 11 PM...UNLESS THE ACTIVITY SETTLES DOWN BEFORE THEN. TOMORROW...WE WILL STILL HAVE THE HUMIDITY AROUND...BUT SLOWLY THE COLUMN WILL DRY OUT AS THE NORTHERN TROUGH SHIFTS TO OUR SOUTH AND RUNS OUT OF SUPPORT. STILL...SURFACE BASED CAPES ARE HIGH (NARROW) AND WITH SOME SUBSIDENCE...A CAP WILL BEGIN TO FORM. WITH THE WET GROUND WILL KEEP A SLIGHT CHANCE GOING FOR THE AFTERNOON...BUT THE ACTIVITY SHOULD BE A LOT LESS THAN TODAY AND MORE PROGRESSIVE. BY THURSDAY INTO FRIDAY...THE TROUGH RETROGRADES INTO A CUTOFF TO OUR SOUTHWEST...AND A RIDGE BUILDS OVERHEAD. NOW...IT WILL GET RATHER HOT...BUT NOT AS HUMID. WE SHOULD BE CAPPED PRETTY FIRMLY. HOWEVER...AGAIN WITH THE MOIST GROUND...WOULD NOT BE SURPRISED IF AN ISOLATED SHOWER OR STORM POPS UP BUT BELIEVE RIGHT NOW THE CHANCES OF THAT HAPPENING ARE < 20 AND NOT ENOUGH TO WORTH MENTION. .EXTENDED...THE MODELS HAVE FINALLY COME AROUND AND THE GFS IS PRETTY MUCH ON BOARD WITH THE OLD EUROPEAN. THEY BOTH TAKE THE NEXT UPSTREAM TROUGH AND MOVE IT QUICKLY TO OUR EAST...AS ANOTHER TROUGH DROPS EAST...BUT MUCH FURTHER EAST THAN THE ONE THAT HAS PLAGUED US FOR THE PAST 11 DAYS. LOOKS AS IF WE WILL BE ON THE ANTICYLONIC SIDE OF IT...WITH A FRESH CANADIAN HIGH BUILDING IN ON SATURDAY. THE COLD FRONT LOOKS TO GO THROUGH FRIDAY NIGHT. BY CROSSING AT NIGHT THIS SHOULD MINIMIZE ANY CONVECTION. ALSO...THE ONLY UPPER AIR SUPPORT (WEAK AT THAT) IS ACROSS OUR NORTHERN ZONES SO WILL KEEP CHC IN THOSE ZONES ONLY. A WEAK SHORT WAVE LOOKS TO MOVE BEHIND THE FRONT ON SATURDAY. WITH A NW FLOW...WILL THROW A CHANCE OF SHOWERS AGAIN TO MY NORTH DURING THE AFTERNOON. SUNDAY LOOKS REALLY NICE FROM THIS VANTAGE POINT...LOW HUMIDITY AND COMFORTABLE TEMPS. ANOTHER FAST MOVING COLD FRONT MIGHT BRING SOME SHOWERS MONDAY...BUT IT SHOULD MOVE ALONG...AS ANOTHER CANADIAN HIGH BUILDS IN BEHIND THAT FOR MIDWEEK. .HYDROLOGICAL DISCUSSION...MORE HEAVY RAINERS IN STORE FOR THIS EVENING. HEAVY RAIN IN CENTRAL HAMILTON AND SOME MORE ACROSS VERMONT. SAME OLD DEAL...MOST AREAS WILL NOT RECEIVE THAT MUCH RAIN...BUT A FEW SPOTS COULD HAVE LOCALIZED FLOODING. THE SHOWERS HAVE NOT BEEN A LONG LASTING AS YESTERDAY AND SO FAR HAS LEFT BEFORE DOING ANY SUBSTANTIAL FLOODING. AFTER THIS EVENING...THE THREAT OF FLASH FLOODING WILL BEGIN TO DIMINISH. ONLY WIDELY SCATTERED ACTIVITY EXPECTED ON WEDNESDAY...AND ISOLATED (AT MOST) THURSDAY AND FRIDAY. THE WEEKEND LOOKS MAINLY RAINFREE...SO FINALLY WE CAN DRY OUT .ALY...FLOOD WATCH FOR THE ENTIRE COUNTY WARNING AREA THIS AFTERNOON AND EVENING. HWJIV
