UPDATE...
MADE FEW CHANGES OTHER THAN ADJUSTING HOURLY THERMAL PROFILES.
MAIN AREA OF HEAVY RAIN IS NOW MOVING INTO EASTERN MAINE WITH THE
MOST CONVECTIVE ELEMENTS OVER ANDROSCOGGIN AND CUMBERLAND
COUNTIES. THESE FEATURES ARE HELPING TO CONTRIBUTE TO VERY HEAVY
DOWNPOURS WITH DUAL POL 1 HR ACCUMULATIONS OF AROUND 0.75" AND
DUAL POL INSTANTANEOUS RAINFALL RATES AS HIGH AS 4-5 IN/HR. WRF
ARW/NMM SHOW THIS CONVECTIVE SYSTEM TRANSLATING EAST OVER THE NEXT
FEW HOURS AND INTENSIFYING AS IT DOES SO. SHOULD BE ABLE TO DROP A
FEW COUNTIES FROM THE FF WATCH SHORTLY.
&&
525 PM UPDATE...HAVE UPDATED THE FORECAST A BIT TO ACCOUNT FOR
LATEST TRENDS IN OBSERVATIONAL DATA. ADJUSTED POP TIMING A LITTLE
BIT. DID NOT TAKE DOWN THE FLASH FLOOD WATCH FOR SOUTHWESTERNMOST

THIS PLUME OF HEAVY RAINFALL WILL CONTINUE MOVING EASTWARD ACROSS
THE CWA THIS EVENING AND OVERNIGHT. WE THINK MOST FOLKS WILL SEE

THE WHITE MOUNTAINS AND MAINE FOOTHILLS WILL ENHANCE RAINFALL
RATES...WITH A FEW LOCATIONS POSSIBLY GETTING UPWARDS OF 4

TEMPER AMOUNTS. AT LEAST ISOLATED FLASH FLOODING IS

FLOW BEHIND THE FRONT WILL HELP KEEP TEMPS UP. EXPECT LOWS IN THE
MID TO UPPER 30S NORTH AND LOWER TO MID 40S SOUTH.
SUNDAY LOOKING COOL AND BLUSTERY AS STRONG NORTHWEST FLOW PERSISTS
ACROSS THE REGION. EXPECT MOSTLY CLOUDY SKIES IN THE MOUNTAINS
