A BROAD UNORGANIZED UPPER-LEVEL LOW OVER THE ROCKIES WILL SLOWLY
WEAKEN BY MONDAY MORNING. IN CONTRAST, AN UPPER-LEVEL RIDGE OVER
THE UPPER MIDWEST AND SOUTH-CENTRAL CANADA WILL SLOWLY MOVE
WESTWARD TO THE NORTHERN PLAINS. THE UPPER-LEVEL ENERGY WILL DRAW
MOISTURE NORTHWARD OVER THE SOUTHERN PLAINS AND THE UPPER-LEVEL
HIGH WILL STEER THE MOISTURE INTO THE HIGH PLAINS. THE MOISTURE
WILL PRODUCE SHOWERS AND THUNDERSTORMS, 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 SATURDAY INTO SUNDAY MORNING. THE ASSOCIATED HEAVY RAIN
WILL CREATE MAINLY LOCALIZED AREAS OF FLASH FLOODING, WITH URBAN
AREAS, ROADS, AND SMALL STREAMS THE MOST VULNERABLE. IN ADDITION,
A SECOND AREA OF SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER PARTS
OF MONTANA AND WYOMING. THEREFORE, THE WPC HAS ISSUED A SLIGHT
RISK OF EXCESSIVE RAINFALL OVER PARTS OF THE NORTHERN
ROCKIES/NORTHERN HIGH PLAINS ON SATURDAY INTO SUNDAY MORNING. THE
ASSOCIATED HEAVY RAIN WILL CREATE MAINLY LOCALIZED AREAS OF FLASH
FLOODING, WITH URBAN AREAS, ROADS, AND SMALL STREAMS THE MOST
VULNERABLE.
FURTHERMORE, WEAK UPPER-LEVEL ENERGY EXTENDING FROM THE GREAT
LAKES TO THE CENTRAL APPALACHIANS WILL CREATE SHOWERS AND
THUNDERSTORMS OVER PARTS OF THE OHIO VALLEY, CENTRAL APPALACHIANS,
AND THE MID-ATLANTIC DURING THE LATE AFTERNOON SATURDAY INTO LATE
SATURDAY NIGHT.
ON SUNDAY, THE THREAT OF EXCESSIVE RAINFALL CONTINUES AS SHOWERS
AND THUNDERSTORMS DEVELOP OVER NORTHWESTERN TEXAS. THEREFORE, THE
WPC HAS ISSUED A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF
THE SOUTHERN HIGH PLAINS FROM 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. FURTHERMORE, THE SHOWERS AND THUNDERSTORMS CONTINUE
OVER PARTS OF THE NORTHERN ROCKIES, CREATING LIGHT TO MODERATE
RAIN OVER THE AREA.
ELSEWHERE, UPPER-LEVEL ENERGY MOVING SOUTHWARD OVER NEW ENGLAND
WILL TRIGGER RAIN SHOWERS OVER THE REGION THROUGH MONDAY MORNING.
ADDITIONALLY, TROPICAL MOISTURE OVER FLORIDA WILL CREATE SHOWERS
AND THUNDERSTORMS OVER THE STATE THROUGH MONDAY. FURTHER, TROPICAL
STORM ARLENE OVER THE EASTERN GULF OF MEXICO WILL MOVE
SOUTHEASTWARD TOWARDS CUBA AND DISSIPATE BY MONDAY.
