...LINGERING SHOWERS AND STORMS EXPECTED ACROSS THE SOUTHEAST
TODAY AND FLORIDA THROUGH MONDAY...
...ABOVE AVERAGE TEMPERATURES FORECAST THROUGHOUT THE SOUTHWEST,
WITH BELOW AVERAGE READINGS FOR MOST LOCATIONS EAST OF THE
ROCKIES...
STRONG HIGH PRESSURE OVER THE CENTRAL U.S. TODAY IS SET TO SLIDE
EASTWARD BY EARLY THIS WEEK AND WILL ALLOW FOR MOSTLY TRANQUIL
WEATHER CONDITIONS ACROSS THE NATION. A LINGERING FRONTAL BOUNDARY
ALONG THE SOUTHEAST WILL PRODUCE ADDITIONAL SCATTERED SHOWERS AND
THUNDERSTORMS THROUGH TONIGHT ACROSS THE CAROLINAS, GEORGIA, AND
NORTHERN FLORIDA. RAINFALL AMOUNTS ARE EXPECTED TO REMAIN MOSTLY
LIGHT AS THE ACTIVITY QUICKLY RACES TO THE EAST, WITH RAINFALL
CHANCES ON MONDAY CONFINED TO THE FLORIDA PENINSULA. AS THE
AFOREMENTIONED FRONTAL BOUNDARY CROSSES CENTRAL FLORIDA TO START
THE NEW WORKWEEK, A FEW STORMS COULD STRENGTHEN ENOUGH TO CONTAIN
DAMAGING WIND GUSTS AND HAIL. THE STORM PREDICTION CENTER HAS
ISSUED A MARGINAL RISK (LEVEL 1/5) FOR SEVERE WEATHER ACROSS PARTS
OF THE CENTRAL AND SOUTHERN FLORIDA PENINSULA IN ORDER TO
HIGHLIGHT THIS POTENTIAL.
OUTSIDE OF A FEW RAIN AND SNOW SHOWERS ACROSS NEW ENGLAND
ASSOCIATED WITH AN APPROACHING COLD FRONT ON SUNDAY NIGHT, THE
ONLY OTHER AREAS WITH NOTABLE PRECIPITATION WILL BE LINKED TO A
LOW PRESSURE SYSTEM AND ATTACHED COLD FRONT STRETCHING FROM THE
UPPER GREAT LAKES TO THE CENTRAL PLAINS MONDAY NIGHT. RAINFALL
AMOUNTS ARE EXPECTED TO REMAIN MEAGER AND MOSTLY UNDER A HALF INCH
THROUGH TUESDAY AS THE SYSTEM SWINGS INTO MIDWEST AND OHIO VALLEY.
TEMPERATURES ACROSS THE COUNTRY WILL REMAIN SPLIT TODAY, WITH
WARMTH IN THE SOUTHWEST AND COOLER THAN AVERAGE HIGHS ACROSS THE
CENTRAL AND EASTERN UNITED STATES. AS HIGH PRESSURE WEAKENS AND
SLIDES EAST, A GRADUAL WARM UP CAN BE EXPECTED EAST OF THE
ROCKIES. THE GREATEST TURNAROUND IS ANTICIPATED OVER THE SOUTHERN
PLAINS, WHERE HIGHS IN THE 60S TODAY COULD BE REPLACED BY 80S ON
TUESDAY. MEANWHILE, LOWS INTO THE 20S AND 30S THIS MORNING ARE
LIKELY TO LEAD TO FROST/FREEZE CONCERNS THROUGHOUT THE MIDWEST AND
PARTS OF THE OHIO VALLEY. CHILLY MORNING TEMPERATURES ARE ALSO
EXPECTED TO LINGER ON MONDAY, BEFORE COOL WEATHER ERODES TO THE
NORTHEAST ON TUESDAY WITH PORTIONS THE APPALACHIANS, MID-ATLANTIC,
AND NORTHEAST WAKING UP TO FROSTY TEMPERATURES IN THE 30S.
