...SEVERE WEATHER AND FLASH FLOODING THREATS CONTINUE ACROSS
PORTIONS OF THE CENTRAL AND SOUTH-CENTRAL U.S. THE NEXT FEW DAYS
...
...INTENSE HEAT PERSISTS ACROSS PARTS OF THE WEST, SOUTHERN
PLAINS, AND FLORIDA THROUGH FRIDAY...
...ELEVATED FIRE WEATHER FOR PORTIONS OF THE GREAT BASIN AND FOUR
CORNERS THROUGH TOMORROW...
AN ACTIVE SUMMERTIME WEATHER PATTERN WILL MAINTAIN DAILY THREATS
OF SCATTERED SEVERE WEATHER AND FLASH FLOODING ACROSS PARTS OF THE
CENTRAL AND SOUTH-CENTRAL U.S. THROUGH MID TO LATE WEEK. A FEW
SLOWER-MOVING DISTURBANCES AND FRONTAL BOUNDARIES WILL INTERACT
WITH AN ABUNDANCE OF GULF MOISTURE AND INSTABILITY, SETTING THE
STAGE FOR SEVERAL ORGANIZED CLUSTERS OF THUNDERSTORMS THE NEXT FEW
DAYS. THE STRONGEST SEVERE STORMS WILL HAVE THE POTENTIAL TO
PRODUCE DAMAGING WINDS, LARGE HAIL, AND A FEW TORNADOES FROM THE
HIGH PLAINS INTO THE OZARKS. IN ADDITION TO THE SEVERE WEATHER,
INTENSE RAINFALL RATES IN THESE STORMS COULD YIELD SCATTERED
INSTANCES OF FLASH FLOODING OVER MUCH OF THE SAME AREA. WEST OF
THE ROCKIES, AFTERNOON THUNDERSTORMS CAPABLE OF DAMAGING WIND
GUSTS AND ISOLATED EXCESSIVE RAINFALL ARE EXPECTED OVER THE GREAT
BASIN OWING TO AN INFLUX OF MOISTURE ON THE PERIPHERY OF A BROAD
UPPER-LEVEL RIDGE.
THROUGH FRIDAY, MUCH OF THE NORTHERN PLAINS AND GREAT LAKES CAN
ENJOY UNSEASONABLY COOL WEATHER WITH THE ARRIVAL OF MILD CANADIAN
AIR BEHIND A NORTHERN TIER COLD FRONT. IN CONTRAST, PARTS OF THE
WEST, SOUTHERN PLAINS, AND FLORIDA WILL CONTINUE TO BAKE UNDER
INTENSE HEAT THE NEXT TWO DAYS. HIGH TEMPERATURES ACROSS THESE
HEAT-STRICKEN REGIONS WILL RUN FROM THE 90'S INTO THE TRIPLE
DIGITS, PROMPTING NUMEROUS HEAT ADVISORIES AND EXTREME HEAT
WARNINGS THROUGH TODAY AND THURSDAY. THUNDERSTORMS COULD PROVIDE
SOME RELIEF FROM THE HEAT IN THE WEST, ALTHOUGH BY FRIDAY MUCH
COOLER WEATHER WILL BEGIN TO OVERTAKE THE REGION AS A LARGE CLOSED
LOW AND ASSOCIATED FRONTAL SYSTEM ARRIVE FROM THE EASTERN PACIFIC.
THE WARMTH, DRY FUELS, AND GUSTY WINDS WILL ALSO MAINTAIN ELEVATED
FIRE WEATHER CONDITIONS ACROSS PARTS OF THE GREAT BASIN AND FOUR
CORNERS THROUGH TOMORROW.
