...HEAVY RAIN AND THUNDERSTORMS TO PERSIST ACROSS THE SOUTHEAST
AND LOWER MISSISSIPPI VALLEY THROUGH THE END OF THE WEEK...
...A NEW FRONTAL SYSTEM, ORIGINATING FROM THE NORTHERN ROCKIES,
WILL BRING SHOWERS AND THUNDERSTORMS THROUGH THE MIDWEST AND GREAT
LAKES BEFORE REACHING THE NORTHEAST...
...TEMPERATURES TO REMAIN BELOW AVERAGE ACROSS MUCH OF THE CENTRAL
U.S., WHILE THE NORTHWEST CONTINUES TO MODERATE...
NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MAKE WEATHER
HEADLINES ACROSS THE GULF COAST REGION THROUGH SATURDAY IN THE
GENERAL VICINITY OF A STALLED FRONTAL BOUNDARY. AREAS FROM
SOUTHEASTERN TEXAS TO THE FLORIDA PANHANDLE HAVE THE POTENTIAL TO
GET 1 TO 2 INCHES OF ADDITIONAL RAINFALL, WITH SOME LOCALIZED 3+
INCH AMOUNTS POSSIBLE WITH MORE PERSISTENT THUNDERSTORMS ACROSS
PORTIONS OF LOUISIANA AND SOUTHERN MISSISSIPPI. IN TERMS OF SEVERE
WEATHER POTENTIAL, A SLIGHT RISK REMAINS VALID THROUGH TONIGHT
FROM THE STORM PREDICTION CENTER ACROSS PORTIONS OF THE FLORIDA
PANHANDLE, AND A MARGINAL RISK GOING INTO FRIDAY AND SATURDAY
EXTENDING FROM THERE TO THE SOUTHERN PLAINS.
FARTHER NORTH, THE SURFACE LOW-PRESSURE SYSTEM THAT DEVELOPED OVER
THE NORTHERN PLAINS AND ROCKIES WILL PROGRESS SOUTHEASTWARD ACROSS
THE MIDWEST AND GREAT LAKES REGION THROUGH THE REMAINDER OF THE
WEEK. THIS SYSTEM WILL BE SUPPORTED BY A MID-LEVEL SHORTWAVE
TROUGH THAT WILL PROVIDE THE NECESSARY LIFT FOR WIDESPREAD SHOWERS
AND THUNDERSTORMS ACROSS THE OHIO VALLEY AND INTO PARTS OF THE
MID-ATLANTIC BY FRIDAY MORNING. AS THE SYSTEM CONTINUES ITS
EASTWARD TREK, PRECIPITATION WILL EXPAND INTO THE NORTHEAST AND
NEW ENGLAND TO END THE WORK WEEK. HIGH-ELEVATION REGIONS IN THE
INTERIOR NORTHEAST COULD SEE A BRIEF TRANSITION TO A WINTRY MIX
DURING THE OVERNIGHT HOURS AS COOLER AIR FILTERS IN BEHIND THE
SYSTEM.
IN THE WAKE OF THE LATE-SEASON WINTER STORM ACROSS THE ROCKIES, A
COOLER AIR MASS WILL REMAIN ENTRENCHED OVER THE CENTRAL AND
EASTERN PORTIONS OF THE COUNTRY. MEANWHILE, IN THE WEST,
ABOVE-AVERAGE CONDITIONS WILL CONTINUE AS THE UPPER-LEVEL TROUGH
VACATES THE REGION AND AN UPPER-LEVEL RIDGE MOVES IN. TEMPERATURES
WILL HOVER AROUND THE UPPER 70S AND LOW 80S TO END THE WEEK, WHILE
PARTS OF THE DESERT SOUTHWEST WILL RETURN TO EXCEEDING 100 DEGREES.
