...RELIEF FROM THE HEAT IS ON THE WAY...

QUESTION IS HOW MUCH (IF ANY) TSTM ACTIVITY WILL PRECEDE/ACCOMPANY THE
COOL DOWN ACRS CNTRL NYS AND NE PA. AGAIN NOT A HIGH CONFIDENCE
FCST.

COMBINATION OF SUBSIDENCE BEHIND 1ST MCS AND SLIGHTLY LOWER SFC
TEMPS/TDS HAS PRETTY MUCH SQUASHED ACTIVITY SO FAR THIS AFTN WITH XCPTN
OF A FEW CELLS WHICH HAVE DVLPD ALONG LAKE BREEZE NEAR ROC. ALSO SOME
INDICATION FROM SAT PIX THAT CELLS MAY BE TRYING TO DVLP ACRS THE WRN
SRN TIER OF NY. IN GNRL THE MDLS SUGGEST A SPLIT TNGT WITH SOME ACTION
TO OUR N AND PSBL MCS DVLPMNT TO OUR W...WITH THCK DIFFLUENCE SUGGESTING
ANY MCS WOULD TRACK SE INTO THE OH VLY AND WRN PA.

WILL KEEP IN A 30 POP FOR THIS EVNG OR UNTIL MIDNIGHT...THEN JUST
KEEPING SKIES PARTLY CLOUDY OVERNIGHT. AGAIN CANT RULE OUT ISOLD OR
WDLY SCT ACTIVITY ANY TIME TNGT BUT GIVEN DVLPMNTS SO FAR THINK BEST
POTNL WILL BE THIS EVNG. CDFNT WILL PASS THE RGM TMRW...AGAIN THE POTNL
IS THERE FOR SOME STRONG TSRA BUT PARAMS ARE NOT IN SYNC. ALTHO LIS
ARE -2 TO -4...ETA/NGM CONTINUE TO SHOW A MINIMUM IN K INDEX VALUES ACRS
CNTRL NYS/NRN PA. IN ADDN LL MSTR CONVERGENCE FIELDS ARE WEAK AT BEST.
COULD SEE THE FNT GOING THRU DRY TMRW....BUT WE ALL KNOW WHAT CAN
HAPPEN IN NW FLOW EVENTS. WILL RETAIN A 30 POP FOR SHRA/TSRA.

MAINLY CLEAR SKIES TMRW NIGHT...BECOMING COOLER AND LESS HUMID. COULD
SEE A FAIR AMT OF SCT-BKN STRATO-CU ON SAT WITH DECENT CAA AND CYCLONIC
FLOW ALOFT...SO PARTLY SUNNY WITH MAXES L/M70S.

COORD WITH BUF. ZONES BY 215. LATER...

.BGM...NONE.
