NWS Buffalo, NY wrote its last area forecast discussion before the first event at Aug 19, 1:02 PM EST, 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 202 PM EDT SUN AUG 19 2001 SHOWERS AND SCATTERED THUNDERSTORMS CONTINUE TO FIRE UP ALONG THE WARM FRONT THAT EXTENDS FROM CENTRAL MICHIGAN TO NORTH CENTRAL PA. THE STRONGEST STORMS ARE CURRENTLY DEVELOPING ACROSS THE EASTERN FINGER LAKES AND JUST WEST OF LAKE ONTARIO. THESE AREAS HAVE SEEN MORE SUNSHINE AND CONSEQUENTLY HAVE HIGHER CAPES AND LOWER LI/S. WE WILL HAVE TO KEEP A CLOSE EYE ON THE STORMS ACROSS THE FINGER LAKES WHERE THERE IS GREATER HELICITY. THE POTENTIAL FOR STRONG TO SEVERE STORMS STILL EXISTS ACROSS WESTERN NEW YORK...IF THE CLOUDS THIN OUT MORE. OTHERWISE...NOT TOO MANY CHANGES FROM THE EARLIER MODEL RUNS. THE SURFACE LOW IS FORECAST TO MOVE SLOWLY TO THE NORTHEAST AND THEN TRACK JUST NORTH OF LAKE ONTARIO ON MONDAY BEFORE REACHING QUEBEC PROVINCE TUESDAY MORNING. THE STEADIER SHOWERS AHEAD OF THE WARM FRONT ARE STILL FORECAST TO LIFT NORTH OF NEW YORK STATE AFTER MIDNIGHT. THE DRY SLOT WILL BRING DRY WEATHER TO MUCH OF OUR FA MONDAY MORNING...BUT THE COMBINATION OF THE DEEP LAYERED CYCLONIC FLOW AND COLD AIR ALOFT WILL GENERATE MORE SHOWERS AND THUNDERSTORMS DURING THE AFTERNOON. TUESDAY WILL STILL BE RATHER UNSETTLED ACROSS THE FINGER LAKES AND THE NORTH COUNTRY...BUT AREAS TO THE WEST SHOULD SEE SOME CLEARING AS DRIER AND MORE STABLE IN AIR WORKS IN FROM THE WEST. .BUF...NONE.
