...THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PARTS OF THE
SOUTHERN PLAINS AND THE LOWER MISSISSIPPI/TENNESSEE VALLEYS ON
MONDAY AND OVER THE SOUTHERN PLAINS, LOWER MISSISSIPPI
VALLEY/SOUTHEAST, AND OHIO VALLEY/CENTRAL APPALACHIANS ON
TUESDAY...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE SOUTHERN PLAINS/LOWER MISSISSIPPI VALLEY ON MONDAY AND
TUESDAY...
A QUASI-STATIONARY FRONT EXTENDING FROM THE SOUTHEAST TO THE
SOUTHERN PLAINS AND CENTRAL ROCKIES WILL HAVE A WAVE OF LOW
PRESSURE MOVE INTO THE OHIO VALLEY BY WEDNESDAY. MOISTURE FLOWING
NORTHWARD OUT OF THE GULF OF AMERICA WILL OVERRUN THE BOUNDARY,
CREATING SHOWERS AND THUNDERSTORMS WITH HEAVY RAIN OVER PARTS OF
THE SOUTHERN PLAINS AND LOWER MISSISSIPPI/TENNESSEE VALLEYS.
THEREFORE, THE WPC HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF
EXCESSIVE RAINFALL OVER PARTS OF THESE AREAS THROUGH TUESDAY
MORNING. THE ASSOCIATED HEAVY RAIN WILL CREATE MAINLY LOCALIZED
AREAS OF FLASH FLOODING, WITH URBAN AREAS, ROADS, SMALL STREAMS,
AND LOW-LYING AREAS THE MOST VULNERABLE.
SEVERE THUNDERSTORMS WILL DEVELOP OVER PARTS OF THE SOUTHERN
PLAINS/LOWER MISSISSIPPI VALLEY. THEREFORE, THE SPC HAS ISSUED A
SLIGHT RISK (LEVEL 2/5) OF SEVERE THUNDERSTORMS OVER PARTS OF THE
SOUTHERN PLAINS/LOWER MISSISSIPPI VALLEY THROUGH TUESDAY MORNING.
THE HAZARDS ASSOCIATED WITH THESE THUNDERSTORMS ARE FREQUENT
LIGHTNING, SEVERE THUNDERSTORM WIND GUSTS, HAIL, AND A FEW
TORNADOES. HOWEVER, THERE IS AN INCREASED RISK OF HAIL, TWO INCHES
OR GREATER, OVER PARTS OF THE SOUTHERN PLAINS.
FURTHER, SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER PARTS OF THE
CENTRAL PLAINS INTO THE NORTHERN ROCKIES ON MONDAY.
ON TUESDAY, THE STATIONARY FRONT STARTS TO MOVE SOUTHEASTWARD OVER
THE SOUTHERN PLAINS AND INTO THE LOWER MISSISSIPPI VALLEY,
PRODUCING SEVERE THUNDERSTORMS. THEREFORE, THE SPC HAS ISSUED A
SLIGHT RISK (LEVEL 2/5) OF SEVERE THUNDERSTORMS OVER TWO AREAS:
THE FIRST AREA OVER THE SOUTHERN PLAINS AND THE SECOND OVER THE
LOWER MISSISSIPPI VALLEY FROM TUESDAY THROUGH WEDNESDAY MORNING.
THE HAZARDS ASSOCIATED WITH THESE THUNDERSTORMS ARE FREQUENT
LIGHTNING, SEVERE THUNDERSTORM WIND GUSTS, HAIL, AND A FEW
TORNADOES. FURTHER, THERE IS AN INCREASED RISK OF HAIL, TWO INCHES
OR GREATER, OVER PARTS OF THE SOUTHERN PLAINS.
MOREOVER, THE THREAT OF EXCESSIVE RAINFALL WILL EXTEND ALONG THE
FRONT FROM THE SOUTHERN PLAINS TO THE SOUTHEAST. THEREFORE, THE
WPC HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL
OVER TWO AREAS, THE SOUTHERN PLAINS AND THE LOWER MISSISSIPPI
VALLEY, INTO THE SOUTHEAST TUESDAY THROUGH WEDNESDAY MORNING. THE
ASSOCIATED HEAVY RAIN WILL CREATE MAINLY LOCALIZED AREAS OF FLASH
FLOODING, WITH URBAN AREAS, ROADS, SMALL STREAMS, AND LOW-LYING
AREAS THE MOST VULNERABLE.
FURTHERMORE, AS THE WAVE OF LOW PRESSURE MOVES INTO THE OHIO
VALLEY, SHOWERS AND THUNDERSTORMS WILL PRODUCE HEAVY RAIN OVER THE
OHIO VALLEY AND CENTRAL APPALACHIANS. THEREFORE, THE WPC HAS
ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER PARTS
OF THE OHIO VALLEY AND CENTRAL APPALACHIANS FROM TUESDAY THROUGH
WEDNESDAY MORNING. THE ASSOCIATED HEAVY RAIN WILL CREATE MAINLY
LOCALIZED AREAS OF FLASH FLOODING, WITH URBAN AREAS, ROADS, SMALL
STREAMS, AND LOW-LYING AREAS THE MOST VULNERABLE.
IN ADDITION, THE WAVE OF LOW PRESSURE WILL PRODUCE RAIN OVER PARTS
OF THE UPPER MIDWEST, LOWER GREAT LAKES, AND MID-ATLANTIC ON
TUESDAY INTO WEDNESDAY. SHOWERS AND THUNDERSTORMS WILL ALSO
DEVELOP OVER THE SOUTHEAST.
MEANWHILE, A FRONT OVER THE PACIFIC NORTHWEST ON MONDAY MOVES
INLAND TO THE NORTHERN ROCKIES AND DISSIPATES OVERNIGHT TUESDAY.
THE SYSTEM WILL PRODUCE LIGHT RAIN OVER PARTS OF THE PACIFIC
NORTHWEST ON MONDAY MORNING AND INTO PARTS OF THE NORTHERN
INTERMOUNTAIN REGION BY LATE MONDAY EVENING AND END OVER THE
NORTHWEST OVERNIGHT MONDAY. ON TUESDAY, THE RAIN WILL MOVE SLOWLY
INTO THE NORTHERN ROCKIES/NORTHERN PLAINS. FURTHERMORE, AN
UPPER-LEVEL LOW WILL DEVELOP OVER THE UPPER MIDWEST MONDAY EVENING
INTO WEDNESDAY, CREATING LIGHT RAIN OVER PARTS OF THE UPPER
MIDWEST.
ELSEWHERE, LINGERING UPPER-LEVEL ENERGY OVER THE NORTHEAST WILL
PRODUCE SCATTERED RAIN AND SHOWERS OVER PARTS OF THE NORTHEAST
THROUGH LATE MONDAY.
