...MULTIPLE ROUNDS OF STRONG TO SEVERE THUNDERSTORMS ARE EXPECTED
TO IMPACT THE NORTHERN AND CENTRAL PLAINS INTO THE UPPER MIDWEST
WITH EXCESSIVE RAINFALL THREATS THROUGH THE NEXT COUPLE OF DAYS...
..SCATTERED LATE-DAY THUNDERSTORMS LINGER ALONG THE EAST COAST
...MAJOR TO LOCALLY EXTREME HEAT RISK ACROSS PORTIONS OF THE
SOUTHWEST FOR TODAY...
A SUMMER WEATHER PATTERN WITH UPPER-LEVEL DISTURBANCES EJECTING
FROM THE NORTHERN ROCKIES WILL SUPPORT MULTIPLE ROUNDS OF STRONG
TO SEVERE THUNDERSTORMS ACROSS MANY LOCATIONS IN THE NORTHERN AND
CENTRAL PARTS OF THE GREAT PLAINS THROUGH THE NEXT COUPLE OF DAYS,
AS THE DISTURBANCES INTERACT WITH A LIFTING WARM FRONT AND A
LEE-SIDE TROUGH. THE THUNDERSTORMS ARE TRIGGERED DURING THE
AFTERNOON TODAY OVER THE NORTHERN PLAINS WHERE THE SEVERE WEATHER
THREAT IS GREATEST, BEFORE TRAVELING EAST INTO THE UPPER MIDWEST
WHERE THE EXCESSIVE RAINFALL THREAT IS GREATEST. SEVERE WIND
GUSTS AND ISOLATED LARGE HAIL ARE POSSIBLE WITH THESE
THUNDERSTORMS. BY FRIDAY, A REINFORCING COLD FRONT WILL PUSH THE
GREATEST THREATS OF SEVERE WEATHER AND HEAVY RAINFALL FARTHER EAST
INTO THE MIDWEST, UPPER MIDWEST, AND INTO THE CENTRAL PLAINS. BY
EARLY SATURDAY INTO SATURDAY MORNING, STRONG THUNDERSTORMS COULD
BE POPPING UP OVER THE CENTRAL HIGH PLAINS ON THE TRAILING PORTION
OF THE FRONT AS A HIGH PRESSURE SYSTEM BRINGS COOLER AND DRIER AIR
FROM WESTERN CANADA INTO THE NORTHERN HIGH PLAINS.
ALONG THE EAST COAST, SCATTERED LATE-DAY THUNDERSTORMS ARE
EXPECTED EACH DAY AS A LEE-SIDE TROUGH REMAINS IN PLACE ACROSS THE
INTERIOR MID-ATLANTIC. ALTHOUGH THE THREAT OF HEAVY RAINFALL AND
SEVERE WEATHER ARE EXPECTED TO BE LOWER THAN IN THE PAST COUPLE OF
DAYS, SOME OF THE STRONGER AND SLOWER-MOVING STORMS COULD RESULT
IN LOCALIZED HEAVY RAIN AND FLOODING ISSUES. THESE SCATTERED
THUNDERSTORMS ARE ALSO EXPECTED TO EXTEND ACROSS THE INTERIOR
SOUTHEAST INTO THE DEEP SOUTH THROUGH THE NEXT COUPLE OF DAYS AT
LEAST. THE WESTERN PORTIONS OF NEW ENGLAND COULD ALSO SEE SOME
STRONG STORMS TODAY BEFORE MORE STABLE AIR FILTERS INTO THE AREA
ON FRIDAY.
A RETROGRADING UPPER RIDGE WILL SUPPORT ABOVE AVERAGE TEMPERATURES
ACROSS THE WEST OVER THE NEXT COUPLE OF DAYS. MAJOR TO ISOLATED
EXTREME HEATRISK IS EXPECTED FOR MUCH OF THE SOUTHWEST TODAY
BEFORE TEMPERATURES BEGIN TO MODERATE THIS COMING WEEKEND.
HEAT-RELATED IMPACTS ARE ALSO POSSIBLE IN AND AROUND SOUTHERN
GEORGIA AND NORTHERN FLORIDA OVER THE NEXT SEVERAL DAYS.
MEANWHILE, ELEVATED THUNDERSTORMS OVER DRY SOILS WILL CONTRIBUTE
TO ELEVATED FIRE DANGER OVER THE FOUR CORNERS REGION TODAY.A
SUMMER WEATHER PATTERN WITH UPPER-LEVEL DISTURBANCES EJECTING FROM
THE NORTHERN ROCKIES WILL SUPPORT MULTIPLE ROUNDS OF STRONG TO
SEVERE THUNDERSTORMS ACROSS MANY LOCATIONS IN THE NORTHERN AND
CENTRAL PARTS OF THE GREAT PLAINS THROUGH THE NEXT COUPLE OF DAYS,
AS THE DISTURBANCES INTERACT WITH A LIFTING WARM FRONT AND A
LEE-SIDE TROUGH. THE THUNDERSTORMS ARE TRIGGERED DURING THE

THUNDERSTORMS. BY FRIDAY, A REINFORCING COLD FRONT WILL PUSH THE
GREATEST THREATS OF SEVERE WEATHER AND HEAVY RAINFALL THREATS
FARTHER EAST INTO THE MIDWEST, UPPER MIDWEST, AND INTO THE CENTRAL
PLAINS. BY EARLY SATURDAY INTO SATURDAY MORNING, STRONG
THUNDERSTORMS COULD BE POPPING UP OVER THE CENTRAL HIGH PLAINS ON
THE TRAILING PORTION OF THE FRONT AS COOLER AND DRIER AIR
ASSOCIATED WITH A HIGH PRESSURE SYSTEM FROM CANADA OVERSPREADS THE
NORTHERN HIGH PLAINS.
