...HEAVY RAINFALL AND THREAT FOR FLASH FLOODING ACROSS THE EASTERN
FLORIDA PENINSULA TONIGHT...
..WET/UNSETTLED WEATHER IN THE WEST THROUGH THE WEEKEND
...ABOVE AVERAGE TEMPERATURES FROM THE MIDWEST TO EAST COAST
FRIDAY; NORTHERN/CENTRAL PLAINS WARM UP THIS WEEKEND...
THE HEAVY RAIN AND WIND THREAT CONTINUES ALONG A QUASI-STATIONARY
SURFACE FRONT DRAPED ALONG THE CENTRAL FLORIDA ATLANTIC COAST
TONIGHT. THERE'S A SLIGHT RISK (AT LEAST 15%) OF EXCESSIVE
RAINFALL LEADING TO FLASH FLOODING FOR THE AREA EXTENDING FROM
NEAR FORT LAUDERDALE UP TO AROUND PALM COAST WHERE 1-1.5" OF RAIN
IS LIKELY AND ISOLATED MAXIMA OF BETWEEN 3-4"+ ARE POSSIBLE. THE
HEAVY RAIN AND WINDS CLEAR OUT ON FRIDAY.
A COLD FRONT MOVING ACROSS THE MIDWEST, GREAT LAKES AND NORTHEAST
WILL BE A FOCUS FOR SHOWERS AND ISOLATED THUNDERSTORMS OVER THE
NEXT COUPLE OF DAYS. TEMPERATURES OUT AHEAD OF THE FRONT WILL BE
ABOVE AVERAGE AS SOUTHERLY FLOW PUMPS WARM AIR INTO THE MIDWEST
AND EAST COAST THROUGH AT LEAST TONIGHT BEFORE THE COLD FRONT
PASSES AND TEMPERATURES BEGIN TO MODERATE. UPPER RIDGING WILL
BUILD OVER THE PLAINS LEADING TO ABOVE AVERAGE TEMPERATURES FOR
THE REGION THIS WEEKEND.
MEANWHILE, A DEEP UPPER-LEVEL LOW WILL BRING SCATTERED SHOWERS AND
THUNDERSTORMS TO CALIFORNIA AND SNOW TO THE SIERRA NEVADA THIS
WEEKEND. THE UPPER LOW WILL PHASE WITH A NORTHERN STREAM TROUGH
AND EXPAND RAINFALL COVERAGE INTO THE PACIFIC NORTHWEST ON
SATURDAY. SNOW LEVELS WILL DROP AS COOL AIR FILTERS INTO THE
REGION, SUPPORTING HEAVY SNOW OVER THE CASCADES ON SATURDAY AND
SUNDAY.
