...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...
HEAVY RAIN 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" ARE 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 THE FOCUS FOR SHOWERS AND ISOLATED THUNDERSTORMS OVER THE
NEXT COUPLE OF DAYS. HIGH WIND WARNINGS ARE IN EFFECT FOR PORTIONS
OF THE NORTHERN PLAINS AND UPPER MIDWEST ALONG A TIGHT PRESSURE
GRADIENT ON THE BACKSIDE OF THE COLD FRONT. 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.
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 ON AS COOL AIR FILTERS INTO THE
REGION, SUPPORTING HEAVY SNOW OVER THE CASCADES ON SATURDAY AND
SUNDAY.
