...STRONG TO SEVERE THUNDERSTORMS EXPECTED FROM THE NORTHERN TO
CENTRAL PLAINS AND UPPER MIDWEST...
..DANGEROUS HEAT CONTINUES ACROSS THE SOUTHEAST AND SOUTHWEST
...ELEVATED TO CRITICAL FIRE WEATHER THREAT ACROSS PORTIONS OF THE
WEST...
A SLOW-MOVING FRONTAL BOUNDARY EXTENDING ACROSS THE NORTHERN
PLAINS INTO THE UPPER MIDWEST WILL BE THE FOCUS FOR SHOWERS AND
THUNDERSTORMS DEVELOPING LATER TODAY AND CONTINUING INTO THE
OVERNIGHT HOURS. SOME OF THESE STORMS ARE EXPECTED TO BECOME
STRONG TO SEVERE, WITH LARGE HAIL AND DAMAGING WINDS POSSIBLE,
ESPECIALLY FROM THE MONTANA AND WYOMING HIGH PLAINS EASTWARD INTO
SOUTHERN MINNESOTA.
ON WEDNESDAY, THE SEVERE WEATHER THREAT SHIFTS FARTHER SOUTH AND
EAST, WITH THE GREATEST POTENTIAL FOR SEVERE THUNDERSTORMS
EXTENDING FROM THE UPPER GREAT LAKES SOUTHWESTWARD INTO THE
CENTRAL PLAINS. IN ADDITION TO SEVERE WIND AND HAIL, LOCALLY HEAVY
RAINFALL MAY LEAD TO AREAS OF FLASH FLOODING. BY THURSDAY, THE
FRONT PUSHES EAST OF THE GREAT LAKES WHILE LINGERING ACROSS THE
CENTRAL PLAINS, SUPPORTING ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS, INCLUDING THE POTENTIAL FOR ADDITIONAL SEVERE
WEATHER.
ISOLATED SEVERE THUNDERSTORMS ARE ALSO POSSIBLE ALONG A STALLED
FRONTAL BOUNDARY EXTENDING FROM VIRGINIA AND NORTH CAROLINA
WESTWARD INTO THE OHIO AND TENNESSEE VALLEYS.
ACROSS THE SOUTHEAST, HOT AND HUMID CONDITIONS WILL PERSIST AND
LIKELY INTENSIFY THROUGH MIDWEEK. ABOVE-NORMAL TEMPERATURES, HIGH
HUMIDITY, AND WARM OVERNIGHT LOWS WILL CONTINUE TO INCREASE THE
RISK OF HEAT-RELATED ILLNESSES, ESPECIALLY FOR THOSE WITHOUT
ACCESS TO ADEQUATE COOLING OR HYDRATION. TEMPERATURES WILL ALSO
REMAIN ABOVE NORMAL ACROSS PORTIONS OF THE SOUTHWEST, WHERE
EXCESSIVE HEAT WARNINGS AND HEAT ADVISORIES REMAIN IN EFFECT
ACROSS PARTS OF ARIZONA AND SOUTHERN CALIFORNIA.
MOSTLY DRY CONDITIONS ARE EXPECTED WEST OF THE ROCKIES. DRY FUELS,
LOW RELATIVE HUMIDITY, AND GUSTY WINDS WILL SUPPORT ELEVATED TO
LOCALLY CRITICAL FIRE WEATHER CONDITIONS ACROSS PORTIONS OF THE
CASCADES, SIERRA NEVADA, GREAT BASIN, AND FOUR CORNERS REGION
THROUGH MIDWEEK.
