...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF THE
SOUTHERN HIGH PLAINS THROUGH TUESDAY...
...TEMPERATURES WILL BE 15 TO 25 DEGREES BELOW AVERAGE OVER NEW
ENGLAND...
WEAK UPPER-LEVEL ENERGY OVER THE GREAT BASIN AND EXTENDING INTO
THE CENTRAL PLAINS SLOWLY RETREATS NORTHWARD TO THE NORTHERN
ROCKIES BY TUESDAY MORNING. HOWEVER, THE UPPER-LEVEL ENERGY WILL
DRAW MOISTURE NORTHWARD OVER THE SOUTHERN PLAINS PRODUCING SHOWERS
AND THUNDERSTORMS AND CREATING HEAVY RAIN OVER PARTS OF THE TEXAS
PANHANDLE. THEREFORE, THE WPC HAS ISSUED A SLIGHT RISK OF
EXCESSIVE RAINFALL OVER PARTS OF THE SOUTHERN HIGH PLAINS ON
SUNDAY INTO MONDAY MORNING. THE ASSOCIATED HEAVY RAIN WILL CREATE
MAINLY LOCALIZED AREAS OF FLASH FLOODING, WITH URBAN AREAS, ROADS,
AND SMALL STREAMS THE MOST VULNERABLE. MOREOVER, THE THREAT OF
EXCESSIVE RAINFALL CONTINUES OVER THE REGION FROM MONDAY INTO
TUESDAY MORNING.
FURTHERMORE, SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER PARTS OF
THE CENTRAL ROCKIES INTO THE NORTHERN INTERMOUNTAIN REGION ON
SUNDAY AND MONDAY. IN ADDITION, MOISTURE TRAPPED UNDER THE
UPPER-LEVEL RIDGE AND WEAK UPPER-LEVEL IMPULSES OVER THE UPPER
MIDWEST WILL PRODUCE SCATTERED SHOWERS AND THUNDERSTORMS OVER THE
AREA THROUGH TUESDAY.
MEANWHILE, BY TUESDAY, AN UPPER-LEVEL LOW OVER NEW ENGLAND MOVES
SLOWLY NORTHEASTWARD INTO SOUTHEASTERN CANADA. THE UPPER-LEVEL LOW
WILL CREATE TEMPERATURES THAT WILL BE 15 TO 25 DEGREES BELOW
AVERAGE OVER THE REGION. IN ADDITION, THE SYSTEM PRODUCES SCATTED
AREAS OF RAIN AND DRIZZLE THROUGH TUESDAY.
MOREOVER, WEAK IMPULSES AND MOISTURE WILL AID IN CREATING SHOWERS
AND THUNDERSTORMS OVER PARTS OF THE CENTRAL APPALACHIANS, OHIO,
AND TENNESSEE VALLEYS ON SUNDAY. THE REGION OF SHOWERS AND
THUNDERSTORMS MOVE TO THE CENTRAL GULF COAST ON MONDAY.
ELSEWHERE, TROPICAL MOISTURE OVER FLORIDA WILL CREATE SHOWERS AND
THUNDERSTORMS OVER THE STATE THROUGH SUNDAY EVENING.
