Area forecast discussion, Jul 1, 10:08 AM EDT, 3 hours 12 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT 1008 AM EDT WED JUL 1 1998 SEVERAL FLASH FLOOD WARNINGS CURRENTLY IN EFFECT ACROSS OUR CWA THIS MORNING. THE LATEST IR SATELLITE PICTURES SHOW CLOUD TOPS CONTINUE TO COOL ACROSS NORTHERN NY AND NORTHWESTERN VT. THIS SPELLS TROUBLE SINCE RAINFALL AMOUNTS ACROSS THESE AREAS HAVE RANGED FROM THE HALF- INCH TO ONE-INCH...WITH SOME LOCALLY HIGHER AMOUNTS. ALREADY SINCE EARLY THIS MORNING. VIGOROUS S/WV MOVING ACROSS CTRL NYS ATTM AS INDICATED BY SATELLITE TRENDS. WOULD EXPECT THE HEAVIEST RAIN TO CONT TO MOVE VERY SLOWLY SOUTHEAST THROUGH THE AFTERNOON HOURS AS S/WV TRACKS SE ACROSS NYS. WITH UPR TROF AND COLD AIR COMING IN ALOFT CANNOT RULE OUT SOME TRW JUST TO ADD TO THE MISERY. WOULD SUGGEST A FEW MINOR CHANGES TO CURRENT ZONE WORDING. INSTEAD OF OCCASIONAL SHOWERS WOULD PREFER TO SAY PERIOD OF RAIN...HEAVY AT TIMES. ALSO...I DONT EXPECT MUCH CHANGE IN TEMPS THIS AFTERNOON SO WOULD PREFER TO SAY TEMPERATURES REMAINING IN THE LOW TO MID 60S. TD
