VALID 12Z THU APR 24 2025 - 12Z SAT APR 26 2025
...ISOLATED TO SCATTERED SEVERE THUNDERSTORMS AND HEAVY RAIN IN
THE CENTRAL AND SOUTHERN PLAINS TODAY...
...HEAVY SNOW POSSIBLE IN THE HIGH ELEVATIONS OF WYOMING TODAY AND
THE SIERRA NEVADA ON SATURDAY...
A SLOW-MOVING FRONTAL BOUNDARY IS EXPECTED TO MOVE SOUTHEAST
ACROSS THE CENTRAL AND EASTERN U.S. OVER THE NEXT COUPLE DAYS AND
WILL BE THE FOCUS FOR DAILY THUNDERSTORM ACTIVITY THROUGH
SATURDAY. TODAY, THE FRONTAL BOUNDARY WILL STRETCH FROM THE GREAT
LAKES TO THE CENTRAL PLAINS WITH A DRY LINE LIKELY EXTENDING TO
THE SOUTH ACROSS WESTERN TEXAS. THE ENVIRONMENT WILL BE FAVORABLE
FOR STRONG TO SEVERE THUNDERSTORM TO DEVELOP TODAY IN THE CENTRAL
AND SOUTHERN PLAINS, WITH WARM MOIST AIR IN PLACE WHILE AN UPPER
LEVEL SHORTWAVE MOVES EAST ACROSS THE REGION. ISOLATED STRONG TO
SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP, AND SEVERE STORM
HAZARDS COULD INCLUDE LARGE HAIL AND STRONG WIND GUSTS.
ADDITIONALLY, THUNDERSTORMS ARE EXPECTED TO PRODUCE HEAVY RAIN,
WHICH MAY LEAD TO ISOLATED TO SCATTERED INSTANCES OF FLASH
FLOODING. THUNDERSTORMS WILL ALSO BE POSSIBLE ACROSS THE SOUTHEAST
TODAY ALONG A DYING STATIONARY BOUNDARY.
THE FRONTAL BOUNDARY WILL GAIN MORE MOMENTUM AS LOW PRESSURE
CONSOLIDATES AND DEEPENS NEAR THE GREAT LAKES ON FRIDAY. THE
BOUNDARY IS EXPECTED TO PUSH INTO THE MISSISSIPPI AND OHIO VALLEYS
ON FRIDAY AND THE NORTHEAST, MID-ATLANTIC, AND SOUTHEAST ON
SATURDAY. SHOWER AND THUNDERSTORM CHANCES WILL MOVE WITH THE
BOUNDARY, AND THERE WILL BE A CONTINUED CHANCE FOR ISOLATED STRONG
TO SEVERE THUNDERSTORMS IN THE SOUTHERN PLAINS WHERE THE TAIL END
OF THE FRONT WILL BECOME STATIONARY. A PORTION OF THE FRONT WILL
ALSO REMAIN STATIONARY UP AGAINST THE ROCKIES, WHICH SHOULD
SUPPORT CONTINUED PRECIPITATION CHANCES THROUGH FRIDAY, WITH HEAVY
SNOW POSSIBLE IN THE HIGHER ELEVATIONS OF WYOMING TODAY.
MEANWHILE, A DEEP UPPER LEVEL LOW IS FORECAST TO APPROACH THE WEST
COAST AND BRING A COLD FRONT TOWARDS THE CALIFORNIA COAST ON
SATURDAY. PACIFIC MOISTURE WILL SPREAD INTO THE WEST, INCREASING
PRECIPITATION CHANCES FRIDAY AND SATURDAY. WIDESPREAD RAIN AND
HIGH ELEVATION SNOW ARE EXPECTED, AND SNOW MAY BE HEAVY IN THE
SIERRA NEVADA ON SATURDAY.
TEMPERATURES WILL GENERALLY BE ABOVE AVERAGE FOR AREAS OF THE
CENTRAL AND EASTERN U.S. ON THE SOUTHERN SIDE OF THE FRONTAL
BOUNDARY TODAY AND FRIDAY, WITH HIGHS IN THE 70S AND 80S, WHILE
AREAS ON THE NORTHERN SIDE ARE A BIT COOLER. BELOW NORMAL
TEMPERATURES SHOULD SPREAD SOUTH AND EAST AS THE FRONT PROGRESSES,
AND BELOW NORMAL TEMPERATURES WILL ALSO DEVELOP ALONG THE WEST
COAST UNDER THE DEEP UPPER LOW.
