...HEAVY RAIN IS POSSIBLE ACROSS PARTS OF THE NORTHEAST AND NEW
ENGLAND THROUGH EARLY THIS WEEKEND...
...FREEZE WATCHES ISSUED THROUGHOUT PORTIONS OF THE
CENTRAL/NORTHERN PLAINS AS COOLER TEMPERATURES OVERSPREAD MUCH OF
THE CENTRAL AND EASTERN UNITED STATES BEHIND A POTENT COLD FRONT...
WIDESPREAD SHOWERS AND THUNDERSTORMS AHEAD OF AN APPROACHING COLD
FRONT AND IN CONJUNCTION WITH MOISTURE SURGING NORTHWARD OF
TROPICAL STORM PHILIPPE ARE FORECAST TO IMPACT THE NORTHEAST AND
NEW ENGLAND BETWEEN THURSDAY AND SATURDAY. LOCALLY HEAVY RAIN
SHOULD BE THE MAIN WEATHER HAZARD, WITH REPEATING ROUNDS OF
MODERATE TO HEAVY RAIN POTENTIALLY LEADING TO INSTANCES OF FLASH
FLOODING. SATURDAY HAS THE GREATEST RISK FOR FLOODING CONCERNS AS
THE COLD FRONT CLASHES WITH INCREASING MOISTURE OFF THE WESTERN
ATLANTIC. A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL IS IN
EFFECT FOR PARTS OF NEW ENGLAND ON SATURDAY, HIGHLIGHTING THE
POTENTIAL FOR SCATTERED FLASH FLOODS. THE CENTER OF PHILIPPE IS
FORECAST TO TRACK CLOSER TOWARDS EASTERN MAINE BY SATURDAY NIGHT,
WHILE LOSING ITS TROPICAL CHARACTERISTICS AND PROVIDING ANOTHER
FOCUS FOR HEAVY RAINFALL.
MEANWHILE, A MUCH COOLER AIRMASS IS OVERSPREADING THE CENTRAL
UNITED STATES BEHIND THE AFOREMENTIONED COLD FRONT AS IT PUSHES
EASTWARD. THE COLDEST TEMPERATURES OF THIS SEASON ARE POSSIBLE
OVER PARTS OF THE PLAINS, AS WELL AS GUSTY WINDS UP TO 50 MPH. LOW
TEMPERATURES BELOW FREEZING FORECAST THROUGHOUT THE CENTRAL AND
SOUTHERN PLAINS ON FRIDAY HAVE PROMPTED FREEZE WATCHES TO BE
ISSUED. THESE FALL-LIKE TEMPERATURES WILL CONTINUE TO INFILTRATE
SOUTH AND EAST BEFORE COVERING A MAJORITY OF THE CENTRAL AND
EASTERN U.S. BY THIS WEEKEND. OVERALL, HIGHS ARE EXPECTED TO
REMAIN 10 TO 20 DEGREES BELOW AVERAGE AND ONLY REACH INTO THE 50S
AND 60S OUTSIDE OF TEXAS AND THE GULF COAST.
ELSEWHERE ACROSS CONUS, MOSTLY DRY AND TRANQUIL WEATHER CAN BE
EXPECTED THROUGH SATURDAY AS HIGH PRESSURE BUILDS INTO THE MIDDLE
PART OF THE NATION. DRY GROUND CONDITIONS, LOW RELATIVE HUMIDITY,
AND GUSTY WINDS BEHIND THE COLD FRONT MAY INCREASE THE FIRE
WEATHER THREAT THROUGHOUT PARTS OF THE CENTRAL GULF COAST ON
SATURDAY, PROMPTING RED FLAG WARNINGS TO BE HOISTED. HOTTER
WEATHER IS FORECAST ACROSS COASTAL SECTIONS OF CENTRAL AND
SOUTHERN CALIFORNIA, WHERE HEAT ADVISORIES HAVE BEEN ISSUED DUE TO
HIGH TEMPERATURES APPROACHING THE UPPER 90S.
