...MAJOR STORM SYSTEM TO BRING HEAVY RAIN, GUSTY WINDS, AND
COASTAL FLOODING FROM FLORIDA TO THE MID-ATLANTIC THIS WEEKEND...
..LIGHT SNOW OVER PARTS OF THE UPPER MIDWEST
THE BIG WEATHER MAKER FOR THIS WEEKEND WILL BE AN INTENSE STORM
TRACKING ACROSS FLORIDA AND UP THE SOUTHEAST COAST WITH LIKELY
IMPACTS TO TRAVEL AS WELL. THIS STORM WILL BRING AN ARRAY OF
WEATHER INCLUDING VERY HEAVY RAINFALL, GUSTY WINDS, COASTAL
FLOODING, AND SOME THREAT FOR SEVERE WEATHER FROM FLORIDA TO THE
MID-ATLANTIC STATES. THE LATEST RAINFALL FORECAST FROM WPC THROUGH
SUNDAY EVENING SHOWS POTENTIAL FOR WIDESPREAD 2-4 INCHES OF RAIN,
WITH LOCALLY HIGHER AMOUNTS ESPECIALLY ALONG THE GEORGIA AND SOUTH
CAROLINA COASTS, INCREASING THE THREAT FOR FLOODING AND FLASH
FLOODING. SOME OF THESE RAINFALL AMOUNTS COULD ALSO APPROACH OR
EXCEED DAILY RAINFALL RECORDS FOR MID-DECEMBER. GUSTY WINDS AND
ONSHORE FLOW WILL ALSO LIKELY BRING COASTAL FLOODING ALONG MUCH OF
THE EAST COAST INTO EARLY NEXT WEEK. THE LOW PRESSURE SYSTEM WILL
DEEPEN AS IT LIFTS UP THE EAST COAST NEXT MONDAY AND TUESDAY AS
WELL, PAST THE SHORT RANGE PERIOD, WITH RAIN AND WIND IMPACTS
MOVING INTO THE NORTHEAST.
ELSEWHERE, A COUPLE OF FRONTS TRACKING FROM THE PLAINS INTO THE
MIDWEST WILL FOCUS SHOWERS FROM THE SOUTHERN PLAINS/GULF COAST
NORTHWARD INTO THE UPPER GREAT LAKES. COLDER AIR FILTERING IN
BEHIND THE FRONTS MAY BRING A PERIOD OF LIGHT TO MODERATE SNOWFALL
ACROSS THE UPPER MIDWEST, WITH GENERALLY ONLY A FEW INCHES OF
ACCUMULATION FORECAST. OUT WEST, A COLD FRONT MOVING TOWARDS
CALIFORNIA MAY BEGIN TO BRING SOME RAIN SHOWERS TO PORTIONS OF THE
NORTHERN AND CENTRAL CALIFORNIA COAST BY SUNDAY AFTERNOON. MUCH OF
THE U.S. THIS WEEKEND WILL EXPERIENCE WELL ABOVE AVERAGE
TEMPERATURES, WITH DAYTIME HIGHS 10 TO 20 DEGREES ABOVE AVERAGE
ACROSS THE WESTERN U.S., NORTHERN TIER, AND INTO THE NORTHEAST.
