WEAK UPPER-LEVEL ENERGY AND MOISTURE OVER THE SOUTHERN PLAINS WILL

OF THE TEXAS PANHANDLE AND NORTHEASTERN NEW MEXICO. THEREFORE, THE
WPC HAS ISSUED A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF
THE SOUTHERN HIGH PLAINS AND SOUTHERN ROCKIES ON MONDAY INTO

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, 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 20 DEGREES BELOW AVERAGE
OVER THE REGION. IN ADDITION, THE SYSTEM PRODUCES SCATTED AREAS OF
RAIN AND DRIZZLE THROUGH WEDNESDAY.
MOREOVER, AN UPPER-LEVEL LOW JUST OFF THE CALIFORNIA COAST WILL
SLOWLY MOVE ONSHORE OVER CALIFORNIA PRODUCING SHOWERS AND
