SO FAR MOST INTERESTING CONVECTION OCCURRED EARLY THIS AFTERNOON
ALONG THE LAKE ONTARIO SHORELINE. ECHOES WERE BOWING IN REGION OF
MID LVL SPEED MAX BUT AGAIN INSTABILITY WAS LACKING AND WEAKENED
QUICKLY IN RAIN COOLED AIR. ANOTHER CLUSTER HAS JUST STARTED OVER
WESTERN NY IN THE WESTERN SRN TIER AND WILL NEED WATCHING.

FROPA AT BGM AROUND 00Z FRI THEN THROUGH FAR SE ZONES BY 06Z. WILL GO
LIKELY POPS WRN/NRN ZONES EARLY THIS EVENING AND CAT UNTIL MIDNIGHT
REST OF FA. BEHIND FRONT AIRMASS WILL DRY TOWARDS MORNING WITH SOME
CLEARING NRN/CNTRL ZONES.

FRIDAY...HIGH PRESSURE OVER SRN ONTARIO WILL ADVECT DRIER AIR ACROSS
FA IN NE FLW. MOISTURE CONTINUES TO LINGER ESP OVR FAR SE ZONES. MS
NORTHERN SECTIONS AN PS ELSEWHERE.

FRIDAY NIGHT...MODEL DIFFERENCES CONTINUE. ETA MOST AGGRESSIVE WITH
DEVELOPING A WEAK SFC LOW OVR WRN PA, NGM/AVN MUCH FARTHER SOUTH.
MID LVL LIFT RATHER WEAK WITH THIS FEATURE WILL CONTINUE WITH JUST
LOW CHC POPS TOWARD MORNING CNTRL SRN TIER.

SATURDAY...WILL GO MORE OPTIMISTIC THAN ETA SOLUTION. PARTLY CLOUDY
NRN ZONES WITH MC CNTRL/SE ZONES. WILL DROP POPS BACK TO CHC IN ALL
AREAS BUT FAR SE ZONES WHERE WEAK SFC LOW MAY GENERATE MORE LIFT IN
MOIST AIRMASS.

REST OF EXTENDED UNCHANGED.
