AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 400 PM EDT FRI AUG 12 2005 .SHORT TERM (TONIGHT THROUGH SUNDAY NIGHT)... EASTERN NEW YORK AND WESTERN NEW ENGLAND ARE NOW WELL IN THE WARM SECTOR. THUNDERSTORMS ARE ACTIVE IN WESTERN AND CENTRAL NEW YORK AND ARE EXPECTED TO CONTINUE TO MOVE TO THE EAST THIS EVENING AND POSSIBLY OVERNIGHT. TRAILING COLD FRONT WILL ARRIVE LATER THAN PREVIOUSLY ANTICIPATED AND NOW WILL BE OVER CENTRAL NEW YORK SATURDAY MORNING AND OVER SOUTHEAST NEW YORK AND ALONG THE PENNSYLVANIA BORDER LATE SATURDAY NIGHT WHERE IT WILL STALL. LOW PRESSURE WILL MOVE BACK INTO THE REGION ALONG THE FRONT SUNDAY. SINCE THE FRONT IS DELAYED WE CAN EXPECT ONE MORE HOT AND HUMID DAY TOMORROW WITH SCATTERED THUNDERSTORMS. RAIN IS LIKELY SUNDAY AND SUNDAY NIGHT. IT WILL HELP TO ALLEVIATE THE CURRENT DRY CONDITIONS BUT RAINFALL WILL NOT BE ENOUGH TO ELIMINATE THEM. && .LONG TERM (MONDAY THROUGH FRIDAY)... 12Z GFS THIS MORNING WAS DIFFERENT FROM EARLIER 00Z GFSLR RUN. MAIN PROBLEM IS WITH TIMING OF SYSTEMS. FLOW ALOFT GENERALLY FAST AND NEARLY ZONAL AND THIS MAKES TIMING DIFFICULT. CHANGED FORECAST FOR MONDAY NIGHT AND TUESDAY FROM CHANCE POPS TO DRY.
