...UNSETTLED WEATHER AND SCATTERED FLASH FLOOD CHANCES EXIST
ACROSS PARTS OF THE CENTRAL/SOUTHERN PLAINS AND FOUR CORNERS
REGION OVER THE NEXT FEW DAYS...
...THREAT OF LOCALLY HEAVY RAINFALL CONTINUES ACROSS THE NORTHEAST
TONIGHT BEFORE THE NEXT ROUND OF SHOWERS AND THUNDERSTORMS ENTER
ON TUESDAY...
...COOLER AND MORE FALL-LIKE TEMPERATURES TO OVERSPREAD MUCH OF
THE CENTRAL UNITED STATES BY EARLY THIS WEEK...
A COLD FRONT CURRENTLY STRETCHING FROM THE MIDWEST TO THE CENTRAL
HIGH PLAINS IS FORECAST TO PUSH SOUTH AND EAST THROUGH EARLY THIS
WEEK, SPREADING RAINFALL CHANCES AND COOLER TEMPERATURES
THROUGHOUT MUCH OF THE NATION'S HEARTLAND. THUNDERSTORMS MAY TURN
SEVERE THROUGH TONIGHT ACROSS PARTS OF THE CENTRAL AND SOUTHERN
HIGH PLAINS, INCLUDING A SLIGHT RISK (LEVEL 2/5) OF SEVERE
THUNDERSTORMS FROM SOUTHWEST KANSAS TO THE TEXAS PANHANDLE.
ADDITIONALLY, HEAVY RAIN MAY LEAD TO INSTANCES OF FLASH FLOODING
OVER A SIMILAR REGION. THE ISOLATED-TO-SCATTERED HEAVY RAIN THREAT
SHIFTS SOUTH INTO TEXAS BY MONDAY, WITH THE WET WEATHER PATTERN
EXPECTED TO LINGER FOR SEVERAL DAYS OVER CENTRAL AND NORTHERN
PORTIONS OF THE STATE. FARTHER WEST, A CONSISTENT FLOW OF PACIFIC
MOISTURE INTO THE SOUTHWEST WILL HELP FUEL SHOWER AND THUNDERSTORM
CHANCES, WHICH COULD PRODUCE SCATTERED FLASH FLOODING OVER
NORTHWEST NEW MEXICO ON TUESDAY.
A LINGERING STATIONARY FRONT OVER THE EAST COAST CONTINUES TO
SPARK SCATTERED SHOWERS AND THUNDERSTORMS FROM THE SOUTHERN
APPALACHIANS TO NEW ENGLAND TODAY. THE GREATEST THREAT ASSOCIATED
WITH THESE STORMS THROUGH TONIGHT IS ANTICIPATED TO BE ASSOCIATED
WITH HEAVY RAIN. SLOW-MOVING THUNDERSTORMS WITH PLENTIFUL
ATMOSPHERIC MOISTURE CONTENT TO WORK WITH WILL BE CAPABLE OF
PRODUCING A FEW INCHES OF RAINFALL WITHIN A SHORT PERIOD OF TIME.
FLOOD WATCHES REMAIN IN EFFECT ACROSS MUCH OF WEST VIRGINIA AND
THE CENTRAL APPALACHIANS, WITH A SLIGHT RISK (2/4) OF EXCESSIVE
RAINFALL EXTENDING FROM SOUTHWEST VIRGINIA TO WESTERN MAINE. BE
SURE TO REMAIN WEATHER AWARE IN THESE REGIONS AND NEVER DRIVE
THROUGH FLOODED ROADWAYS. ISOLATED DOWNPOURS MAY LINGER ACROSS NEW
ENGLAND AND THE NORTHEAST ON MONDAY, BEFORE THE NEXT ROUND OF
UNSETTLED WEATHER ENTERS ON TUESDAY ALONG WITH A STRONGER COLD
FRONT.
AFTER ONE FINAL DAY OF POTENTIALLY RECORD-BREAKING HEAT ACROSS THE
SOUTHWEST AND SOUTHERN TEXAS TODAY, COOLER TEMPERATURES ARE
EXPECTED TO BEGIN THE NEW WORKWEEK. ELSEWHERE, A TASTE OF FALL IS
IN THE FORECAST AS BELOW AVERAGE TEMPERATURES OVERSPREAD THE
CENTRAL U.S. THROUGH TUESDAY. HIGHS INTO THE 70S AND WIDESPREAD
LOWS IN THE 50S AND UPPER 40S ARE EXPECTED FOR MUCH OF THE
CENTRAL/NORTHERN PLAINS, MIDWEST, AND UPPER GREAT LAKES. SLIGHTLY
ABOVE AVERAGE TEMPERATURES ARE LIKELY TO REMAIN ACROSS THE
SOUTHEAST, GULF COAST, AND NORTHERN GREAT BASIN FOR THIS TIME
PERIOD.
