346 AM EDT TUE MAY 28 2024
VALID 12Z TUE MAY 28 2024 - 12Z THU MAY 30 2024
...NUMEROUS STRONG TO SEVERE THUNDERSTORMS AND AREAS OF FLASH
FLOODING LIKELY ACROSS PORTIONS OF NORTHERN AND CENTRAL TEXAS
TODAY...
...UNSETTLED WEATHER WITH THUNDERSTORMS AND HEAVY RAIN POSSIBLE
OVER THE NORTHERN GREAT BASIN/ROCKIES TODAY BEFORE SHIFTING INTO
THE NORTHERN HIGH PLAINS ON WEDNESDAY...
...SWELTERING HEAT CONTINUES ACROSS PARTS OF SOUTH TEXAS AND
SOUTHERN FLORIDA...
THE LONE STAR STATE WILL BE THE FOCUS FOR ACTIVE WEATHER TODAY AS
STRONG THUNDERSTORMS DEVELOP ALONG A SOUTHERN HIGH PLAINS DRYLINE
AND LINGERING STATIONARY FRONT. AMPLE ATMOSPHERIC MOISTURE CONTENT
AND INSTABILITY WILL SUPPORT THE LIKELIHOOD OF STORMS CONTAINING
SIGNIFICANT DAMAGING WIND GUSTS AND VERY LARGE HAIL. ONGOING
THUNDERSTORMS ALONG THE RED RIVER VALLEY OF THE SOUTH ARE EXPECTED
TO CONTINUE THROUGH THE MORNING HOURS BEFORE NUMEROUS ADDITIONAL
STORMS FORM ACROSS WESTERN AND NORTH-CENTRAL TEXAS BY THE
AFTERNOON. MERGING CELLS AND CLUSTERS OF STORMS ARE ALSO LIKELY TO
CONTAIN INTENSE RAINFALL RATES CAPABLE OF TRIGGERING SEVERAL FLASH
FLOODS, PARTICULARLY FOR AREAS JUST WEST OF DALLAS-FORT WORTH AND
NORTH OF AUSTIN. THE THREAT OF SCATTERED FLASH FLOODING AND SEVERE
THUNDERSTORMS INCLUDES A MUCH LARGER REGION EXTENDING FROM THE
TEXAS PANHANDLE TO THE WESTERN GULF COAST. FOR THE OVERNIGHT
TIMEFRAME, HEAVY RAIN AND SEVERE WEATHER CHANCES ARE FORECAST TO
GRADUALLY DECREASE AND SLIDE EASTWARD WITHIN TEXAS. RESIDENTS AND
VISITORS ARE REMINDED TO REMAIN WEATHER AWARE, HAVE NUMEROUS WAYS
TO RECEIVE WARNINGS AND NEVER DRIVE ACROSS FLOODED ROADWAYS.
A COLD FRONT PROGRESSING ACROSS THE NORTHWEST, NORTHERN GREAT
BASIN, AND NORTHERN ROCKIES TODAY WILL PROVIDE ENOUGH FORCING TO
PRODUCE THE POTENTIAL FOR SCATTERED SEVERE THUNDERSTORMS CAPABLE
OF CONTAINING DAMAGING WIND GUSTS FOR PARTS OF NORTHEAST OREGON,
NORTHERN/CENTRAL IDAHO, AND WESTERN MONTANA. A FEW STORMS MAY ALSO
PRODUCE HEAVY RAIN AND ISOLATED FLASH FLOODING. THIS AREA OF
UNSETTLED WEATHER IS EXPECTED TO SWING EASTWARD BY MIDWEEK AND
ENTER THE NORTH-CENTRAL HIGH PLAINS BEFORE AN EXPANDING AREA OF
STORMINESS RETURNS TO THE CENTRAL/SOUTHERN PLAINS ON THURSDAY.
ELSEWHERE, COLD AIR ADVECTION ON THE SOUTHWESTERN PERIPHERY OF AN
EASTERN CANADA LOW PRESSURE SYSTEM WILL PRODUCE SCATTERED AREAS OF
SHOWERS AND STORMS OVER THE NEXT FEW DAYS FROM THE GREAT LAKES AND
UPPER MIDWEST TO THE OHIO VALLEY, MID-ATLANTIC, AND NORTHEAST. A
FEW STORMS COULD CONTAIN HAIL AND BRIEF DAMAGING WINDS TODAY FROM
SOUTHERN WISCONSIN TO NORTHERN ILLINOIS AND NORTHWEST INDIANA.
THE HEAT PLAGUING MUCH OF THE GULF COAST AND SOUTHERN TEXAS IS
FINALLY ABATING, BUT WILL LINGER ACROSS PARTS OF SOUTHERN TEXAS
TODAY WITH HEAT INDICES UP TO 115 DEGREES. HIGH TEMPERATURES ARE
ALSO EXPECTED TO REMAIN ABOVE AVERAGE AND NEAR DAILY RECORD HIGHS
THROUGHOUT THE CENTRAL AND SOUTHERN FLORIDA PENINSULA OVER THE
NEXT FEW DAYS.
