A SLOW-MOVING OCCLUDED FRONT MOVING ACROSS THE NORTHERN PLAINS
WILL PRODUCE SEVERE THUNDERSTORMS AND HEAVY RAIN. THE SEVERE

GUSTS, HAIL, AND A FEW TORNADOES. IN ADDITION, THE WPC HAS ISSUED
A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER PARTS OF THE
NORTHERN PLAINS THROUGH SUNDAY MORNING. THE ASSOCIATED HEAVY RAIN

AREAS, ROADS, SMALL STREAMS, AND LOW-LYING AREAS BEING THE MOST
VULNERABLE. FURTHERMORE, AS THE FRONT MOVES EAST, OVER THE
NORTHERN PLAINS/UPPER MISSISSIPPI VALLEY, SEVERE WEATHER WILL

NORTHERN PLAINS/UPPER MISSISSIPPI VALLEY ON SUNDAY INTO MONDAY

UPPER MISSISSIPPI VALLEY ON MONDAY. THE WPC HAS A MARGINAL RISK OF

SEVERE THUNDERSTORMS OVER PARTS OF THE SOUTHERN MID-ATLANTIC ON
SUNDAY THROUGH MONDAY MORNING. THEREFORE, THE WPC HAS ISSUED A
SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL WITH THESE
THUNDERSTORMS. THE ASSOCIATED HEAVY RAIN WILL CREATE MAINLY
LOCALIZED AREAS OF FLASH FLOODING, WITH URBAN AREAS, ROADS, SMALL
STREAMS, AND LOW-LYING AREAS BEING THE MOST VULNERABLE. THE THREAT
OF EXCESSIVE RAINFALL WILL END ON MONDAY. IN ADDITION, SHOWERS AND
THUNDERSTORMS WILL DEVELOP ALONG AND EAST OF THE DRYLINE ON
