...BLIZZARD CONDITIONS ONGOING IN THE CENTRAL/NORTHERN PLAINS WITH  
A POTENT LATE-SEASON WINTER STORM...  
 
...SEVERE THUNDERSTORMS ARE FORECAST OVER PARTS OF THE CENTRAL  
PLAINS WEDNESDAY...  
   
..EXTREME FIRE WEATHER DANGER FOR THE SOUTHERN HIGH PLAINS
 
 
A STRONG LOW PRESSURE SYSTEM WILL CONSOLIDATE WEDNESDAY NIGHT IN  
THE CENTRAL PLAINS AND MOVE INTO THE MISSISSIPPI VALLEY ON  
THURSDAY NIGHT AS AN UPPER-LEVEL LOW STRENGTHENS AS WELL. HEAVY,  
WET SNOW WILL CONTINUE WEST AND NORTH OF THE SURFACE LOW, AND 1 TO  
2 FEET OF SNOW IS FORECAST FROM NORTHERN NEBRASKA NORTHEASTWARD  
INTO PARTS OF THE DAKOTAS AND MINNESOTA. HIGH WINDS ARE ALSO  
LIKELY, CREATING BLIZZARD CONDITIONS IN THE CENTRAL/NORTHERN  
PLAINS. DIFFICULT TO IMPOSSIBLE TRAVEL CONDITIONS AND POWER  
OUTAGES ARE EXPECTED. FREEZING RAIN IS ALSO A THREAT ALONG THE  
RAIN/SNOW LINE; A QUARTER OF AN INCH OF FREEZING RAIN IS POSSIBLE  
NEAR THE IOWA/MINNESOTA BORDER AND INTO WISCONSIN. FARTHER SOUTH  
IN THE WARM AIR AHEAD OF THE LOW SYSTEM, RAIN AND THUNDERSTORMS  
ARE EXPECTED. AN ENHANCED RISK OF SEVERE THUNDERSTORMS IS IN  
EFFECT FOR THE CENTRAL PLAINS IN THE STORM PREDICTION CENTER'S  
OUTLOOK FOR WEDNESDAY, AND A SLIGHT RISK OF SEVERE WEATHER IS  
EXPECTED ON THURSDAY IN PARTS OF ILLINOIS AND INDIANA. MARGINAL  
RISKS OF EXCESSIVE RAINFALL/FLASH FLOODING ARE IN PLACE FOR  
PORTIONS OF NEBRASKA AND IOWA THROUGH WEDNESDAY NIGHT, AND FOR  
PORTIONS OF THE UPPER GREAT LAKES REGION AND OHIO VALLEY ON  
THURSDAY. RAIN AND THUNDERSTORMS WILL SPREAD INTO THE EASTERN  
SEABOARD ON FRIDAY.  
 
BEHIND THE STORM AND AN ASSOCIATED DRYLINE, CONDITIONS WILL BE  
FAVORABLE FOR FIRE WEATHER THROUGHOUT THE SOUTHWEST AND  
SOUTHERN/CENTRAL PLAINS, AS HIGH SUSTAINED WINDS AND EVEN HIGHER  
GUSTS COMBINE WITH VERY DRY HUMIDITIES. AN EXTREME RISK OF FIRE  
DANGER IS IN PLACE IN THE STORM PREDICTION CENTER'S FIRE WEATHER  
OUTLOOK FOR THE SOUTHERN HIGH PLAINS ON WEDNESDAY. RED FLAG  
WARNINGS ARE WIDESPREAD THROUGHOUT THESE AREAS, AND CRITICAL  
CONDITIONS ARE EXPECTED TO CONTINUE ON THURSDAY. MORE BROADLY,  
GUSTY WINDS ARE A THREAT FROM CALIFORNIA THROUGH THE SOUTHWEST,  
INTERMOUNTAIN WEST, ROCKIES, PLAINS, AND MISSISSIPPI VALLEY FOR  
THE NEXT COUPLE OF DAYS. THE BIGGEST THREAT FOR HIGH WINDS IN THE  
SOUTHERN/CENTRAL PLAINS, WHERE HIGH WIND WARNINGS ARE IN EFFECT.  
 
ELSEWHERE, UPPER-LEVEL ENERGY WILL MOVE THROUGH THE WEST DURING  
THE PERIOD, WHICH WILL CAUSE HIGHER ELEVATION SNOW AND LOWER  
ELEVATION RAIN IN THE PACIFIC NORTHWEST AND INTERMOUNTAIN WEST  
THROUGH THURSDAY NIGHT, SPREADING INTO THE SOUTHWEST AND SOUTHERN  
PLAINS ON FRIDAY. HIGHER ELEVATIONS OF THE CASCADES AND NORTHERN  
ROCKIES COULD SEE 6 TO 12 INCHES OF SNOW THROUGH FRIDAY.
