A SEQUENCE OF SHORTWAVE ENERGIES WILL SUPPORT IMPACTFUL WEATHER

WILL ORGANIZE AHEAD OF A LOW PRESSURE SYSTEM OVER THE MIDDLE/LOWER
MISSISSIPPI VALLEY AND SPREAD INTO THE SOUTHEAST THIS MORNING AND

LEADING TO FLASH FLOODING IS IN EFFECT FOR PORTIONS OF TENNESSEE,
MISSISSIPPI AND ALABAMA TODAY. MEANWHILE, SOME DRY-LINE STORMS
COULD TURN SEVERE OVER PARTS OF THE CENTRAL/SOUTHERN HIGH PLAINS
THIS AFTERNOON. THE STORM PREDICTION CENTER ISSUED A SLIGHT RISK
(LEVEL 2/5) OF SEVERE THUNDERSTORMS FOR THE AFOREMENTIONED AREAS
WITH SUPERCELLS POSSIBLY ORGANIZING INTO CLUSTERS AND SPREADING
INTO THE PLAINS TONIGHT. SEVERE WIND, HAIL AND BRIEF TORNADOES ARE
POSSIBLE.
ANOTHER LOW PRESSURE SYSTEM EMERGING FROM THE ROCKIES WILL BRING A
RENEWED THREAT OF SEVERE WEATHER TO THE NORTHERN/CENTRAL PLAINS
AND UPPER MIDWEST ON SUNDAY. A SLIGHT RISK (LEVEL 2/5) OF SEVERE
THUNDERSTORMS IS IN EFFECT FROM SOUTHEASTERN NORTH DAKOTA TO
WESTERN MINNESOTA AND DOWN INTO CENTRAL NEBRASKA, WHERE A LINE OF
SEVERE STORMS MAY PRODUCE DAMAGING WIND GUSTS AND HAIL COULD BE
THE MAIN SEVERE THREATS. THERE'S ALSO A SLIGHT RISK (AT LEAST 15%)
OF EXCESSIVE RAINFALL LEADING TO FLASH FLOODING OVER PARTS OF
SOUTHERN MINNESOTA, SOUTHEASTERN SOUTH DAKOTA, EASTERN NEBRASKA
AND IOWA ON SUNDAY.
DEEP UPPER-LEVEL TROUGHING WILL BRING RAIN AND COOLER TEMPERATURES
TO THE PACIFIC NORTHWEST ON SUNDAY. TEMPERATURES WILL REMAIN ABOVE
AVERAGE ACROSS SOUTHERN TEXAS, WHILE WARMER CONDITIONS EXPAND
ACROSS THE GREAT PLAINS THROUGH EARLY NEXT WEEK. APPROACHING
SHORTWAVE ENERGY AND AN UPPER LOW LOCKED IN JUST OFF THE NORTHEAST
COAST WILL SUPPORT WARMER THAN AVERAGE TEMPERATURES OVER THE
