THE MAJOR WINTER STORM CONTINUES THROUGH TUESDAY OVER THE CENTRAL
PLAINS INTO THE UPPER MISSISSIPPI VALLEY. SNOW AND STRONG WINDS
WILL CONTINUE FROM THE CENTRAL PLAINS TO NORTHERN MINNESOTA
THROUGH MONDAY NIGHT, ALONG WITH SLEET AND FREEZING RAIN IN PARTS
OF THE UPPER MISSISSIPPI VALLEY.
IN ADDITION, HAZARDOUS IMPACTS WILL BE SNOW, ICING, AND WIND.
BLOWING AND FALLING SNOW WILL SIGNIFICANTLY REDUCE VISIBILITY, AND
BLIZZARD CONDITIONS WILL PERSIST INTO TUESDAY ACROSS PORTIONS OF
THE PLAINS AND NORTHERN MINNESOTA. TRAVEL MAY BE VERY DIFFICULT OR
IMPOSSIBLE AT TIMES. POWER OUTAGES AND TREE DAMAGE ARE POSSIBLE IN
SOME AREAS DUE TO HEAVY SNOW, ICING, AND STRONG WINDS. ALSO, PLAN
ON SLIPPERY ROADS.

NORTHEAST ACROSS THE REGION, WITH GRADUAL IMPROVEMENT ON TUESDAY.
HOWEVER, AREAS OF BLOWING SNOW MAY PERSIST AS SNOW LINGERS INTO
WEDNESDAY OVER PARTS OF THE UPPER GREAT LAKES.
MEANWHILE, THE FRONT ASSOCIATED WITH THE STORM EXTENDS FROM THE
MIDDLE MISSISSIPPI VALLEY/SOUTHERN PLAINS AND MOVES EASTWARD TO
THE LOWER GREAT LAKES INTO THE CENTRAL GULF COAST BY WEDNESDAY
EVENING.
THE SYSTEM WILL CREATE SHOWERS AND SEVERE THUNDERSTORMS OVER THE
LOWER MISSISSIPPI VALLEY. THEREFORE, THE SPC HAS ISSUED AN
ENHANCED RISK (LEVEL 3/5) OF SEVERE THUNDERSTORMS OVER PARTS OF
THE LOWER MISSISSIPPI VALLEY THROUGH TUESDAY MORNING. THE HAZARDS
ASSOCIATED WITH THESE THUNDERSTORMS ARE FREQUENT LIGHTNING, SEVERE
THUNDERSTORM WIND GUSTS, HAIL, AND A FEW TORNADOES. ADDITIONALLY,
THERE IS AN INCREASED THREAT OF EF2 TO EF5 TORNADOS OVER THE AREA.
IN ADDITION, THE SHOWERS AND THUNDERSTORMS WILL PRODUCE HEAVY RAIN
OVER PARTS OF THE MIDDLE/LOWER MISSISSIPPI AND TENNESSEE VALLEYS.
THEREFORE, THE WPC HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF
EXCESSIVE RAINFALL OVER PARTS OF THE MIDDLE/LOWER MISSISSIPPI AND
TENNESSEE VALLEYS THROUGH TUESDAY MORNING. THE ASSOCIATED HEAVY
RAIN WILL CREATE MAINLY LOCALIZED AREAS OF FLASH FLOODING, WITH
URBAN AREAS, ROADS, AND SMALL STREAMS THE MOST VULNERABLE.
BY TUESDAY, THE THREAT OF SEVERE THUNDERSTORMS DECREASES SLIGHTLY
TO A MARGINAL RISK OVER PARTS OF THE GREAT LAKES/OHIO VALLEY, WITH
A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE CENTRAL
GULF COAST. THEREFORE, THE SPC HAS ISSUED A SLIGHT RISK (LEVEL
2/5) OF SEVERE THUNDERSTORMS OVER PARTS OF THE CENTRAL GULF COAST
FROM TUESDAY THROUGH WEDNESDAY MORNING. THE HAZARDS ASSOCIATED
WITH THESE THUNDERSTORMS ARE FREQUENT LIGHTNING, SEVERE
THUNDERSTORM WIND GUSTS, A FEW TORNADOES, AND A MINIMAL THREAT OF
HAIL.
SIMILARLY, THE SHOWERS AND THUNDERSTORMS WILL CREATE HEAVY RAIN
OVER PARTS OF THE CENTRAL/EASTERN GULF COAST. THEREFORE, THE WPC
HAS ISSUED A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER
PARTS OF THE CENTRAL/EASTERN GULF COAST ON TUESDAY THROUGH
WEDNESDAY MORNING. THE ASSOCIATED HEAVY RAIN WILL CREATE MAINLY
LOCALIZED AREAS OF FLASH FLOODING, WITH URBAN AREAS, ROADS, AND
SMALL STREAMS THE MOST VULNERABLE.
ON WEDNESDAY, THE THREAT OF SEVERE THUNDERSTORMS ENDS. HOWEVER,
THE THREAT OF EXCESSIVE RAINFALL CONTINUES OVER PARTS OF THE
EASTERN GULF COAST AND SOUTHEAST. THEREFORE, THE WPC HAS ISSUED A
SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL OVER PARTS OF THE
EASTERN GULF COAST AND SOUTHEAST ON WEDNESDAY. THE ASSOCIATED
HEAVY RAIN WILL CREATE MAINLY LOCALIZED AREAS OF FLASH FLOODING,
WITH URBAN AREAS, ROADS, AND SMALL STREAMS THE MOST VULNERABLE.
ELSEWHERE, FROM TUESDAY EVENING INTO WEDNESDAY, MOISTURE FROM THE
ATLANTIC WILL MOVE ONSHORE OVER NEW ENGLAND, BRINGING WARMER
TEMPERATURES AND TRAPPING COLD AIR IN THE INTERIOR OF NORTHERN NEW
ENGLAND. THE WARM, MOIST AIR WILL CREATE RAIN/FREEZING RAIN OVER
PARTS OF NORTHERN NEW ENGLAND FROM TUESDAY EVENING INTO WEDNESDAY.
FURTHERMORE, A DEEP UPPER-LEVEL TROUGH WILL EXTEND ACROSS THE
WESTERN PORTIONS OF THE U.S. AIDING IN THE DEVELOPMENT
LOWER-ELEVATION RAIN AND HIGHER-ELEVATION SNOW WILL EXTEND FROM
THE PACIFIC NORTHWEST TO SOUTHWEST, AND SOUTHERN ROCKIES THROUGH
TUESDAY EVENING.
HOWEVER, A SURGE OF ENERGY MOVING INTO THE NORTHWEST WILL PRODUCE
