AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BUFFALO NY
913 AM EDT TUE JUL 6 1999

MORNING SATELLITE SHOWS WEAKENING BAND OF CLOUD ASSOC WITH PREVIOUS
CONVECTION LYING ACROSS SRN ONTARIO INTO LOWER MICH ATTM. EARLIER
SHWRS HAVE ALL BUT DISSIPATED AND WE WILL HAVE TO WAIT FOR
REDEVELOPMENT MIDDAY-EARLY AFTERNOON TIME FRAME FOR ANY ACTIVITY FOR
OUR FCST AREA.

BEST DYNAMICS WILL STAY WELL TO OUR NORTH AND EAST WITH 500 MB JET IN
OTTAWA VALLEY AND NRN NEW ENG LATER IN AFTERNOON AND 45 KT 700 MB JET
DROPPING INTO ERN LK ONTARIO REGION DURING AFTERNOON. LOOKS LIKE WE
WILL HAVE TO DEPEND ON HEATING RATHER THAN DYNAMICS...BUT WITH SOUPY
75-DEG DEW PTS...THIS SHOULDNT BE TOO DIFFICULT TO SET SOMETHING OFF.
ETA CAPES GET TO 2000 BY 21Z...BUT NGM ZILCH...THIS DUE TO ERRONEOUS
SFC DEW PTS ON NGM (17C VS 23C ON ETA). STILL...CURRENT FCST MUCH TOO
PESSIMISTIC AND WLL GET UPDATE OUT BY 930. EXPECT STRONG LK ERIE
STABILIZATION AGAIN...SO WLL LOWER POPS TO SCATD FROM BUF TO
ROC...AND HOLD LIKELY TO SOUTH AND EAST...BUT ALSO GO WITH P/SUNNY.
TEMPS WILL APPROACH 90 AWAY FROM LK INFLUENCES...MID 80S NIAG
FRONTIER.

WLL LEAVE IN EVE CHC POP EAST (& INCL IN WRN SRN TIER)...OTWS REST OF
FCST FINE...NICE BREAK IN HEAT/HUMIDITY REST OF WEEK.

POST MORTEM...ALTHOUGH WNY WAS HOT AND HUMID...WE DID NOT GET THE
EXTREME CONDITIONS PREVALENT E OF MOUNTAINS. GEN VALLEY/FINGER LAKES
AND SRN TIER VALLEYS REACHED LO-MID 90S...BUT AREAS NEAR LK ERIE HELD
IN MID-UPPER 80S. DEW PTS WERE UNUSUALLY HIGH THOUGH...HANGING IN MID
70S LAST 3 DAYS. 3-DAY MAXES AT ROC...89...91 AND 92 WERE HIGH BUT
NOT UNUSUAL FOR EARLY JULY...BUF ONLY 89...84 AND 85. NOT A BAD TIME
OF YEAR TO BE UNDER LAKE ERIES INFLUENCE.

THATS IT FROM THE BREEZY BUF. WRKZONES GONE. ON STREET BY 930.
TAKE IT EASY.

.BUF...SCA NR SHORES LK ERIE RIPLEY TO BUF AND BUF HRBR/NIAG RIV.
