NWS Buffalo, NY wrote its last area forecast discussion before the first event at May 27, 8:33 AM EST, 2 hours 54 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BUFFALO NY 933 AM EDT SUN MAY 27 2001 THE WELL DEFINED VORT MAX THAT IS PUSHING THROUGH EASTERN OHIO THIS MORNING WILL APPROACH WESTERN NEW YORK THIS AFTERNOON. THE SHOWERS THAT ARE ASSOCIATED WITH THIS FEATURE ARE ALREADY MOVING INTO CHAUTAUQUA COUNTY...BUT THE CIRCULATION AROUND THE CLOSED UPPER LOW IS DIRECTING THE SHOWERS TOWARD THE NORTH NORTHWEST...SO THERE WILL BE A SLOW EASTWARD PROGRESSION TO THE PCPN. THE DYNAMICS WILL CERTAINLY BE MORE FAVORABLE THIS AFTERNOON WITH THE APPROACH OF THE SHORT WAVE...BUT THE CLOUDS WILL PUT A CAP ON THE HEATING...ESPECIALLY IN THE WEST. HOWEVER...THE PRESENCE OF THE UNSEASONABLY COLD AIR ALOFT WILL STILL SET OFF A FEW THUNDERSTORMS. THE INSTABILITY WILL BE MORE FAVORABLE ACROSS THE GENESEE VALLEY AND THE FINGER LAKES WHERE THE COMBINATION OF MORNING SUNSHINE AND SLIGHTLY HIGHER DEWPOINTS WILL RESULT IN HIGHER CAPES AND LOWER LI/S DURING THE AFTERNOON. THE THUNDERSTORMS WILL TAPER OFF AFTER SUNSET...BUT THE SHOWERS WILL PROBABLY LINGER THROUGH A GOOD PART OF THE NIGHT AS THE SHORT WAVE MOVES EAST ACROSS THE STATE. .BUF...NONE TJP
