A STRONG STORM OVER THE CENTRAL PLAINS WILL MOVE NORTHEASTWARD TO  
NEAR JAMES BAY BY SATURDAY. HEAVY, WET SNOW WILL CONTINUE WEST  
AND NORTH OF THE ASSOCIATED 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. A SLIGHT  
RISK OF SEVERE THUNDERSTORMS IS IN EFFECT FOR THE WESTERN OHIO  
VALLEY IN THE STORM PREDICTION CENTER'S OUTLOOK FOR THURSDAY.  
MARGINAL RISKS OF EXCESSIVE RAINFALL/FLASH FLOODING ARE IN PLACE  
FOR PORTIONS OF THE UPPER GREAT LAKES AND OHIO VALLEY ON THURSDAY.  
SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG AND AHEAD OF THE  
ASSOCIATED FRONT THIS AFTERNOON AND EVENING FROM THE WESTERN OHIO  
VALLEYS SOUTHWARD TO THE LOWER MISSISSIPPI VALLEY. THE SHOWERS AND  
THUNDERSTORMS WILL MOVE EASTWARD TO PARTS OF THE NORTHERN  
MID-ATLANTIC, CENTRAL APPALACHIANS, AND INTO THE CENTRAL GULF  
COAST BY FRIDAY EVENING INTO SATURDAY.  
 
BEHIND THE STORM AND AN ASSOCIATED DRYLINE, CONDITIONS WILL BE  
FAVORABLE FOR FIRE WEATHER THROUGHOUT THE SOUTHWEST AND  
SOUTHERN/CENTRAL PLAINS, AS HIGH WINDS AND HIGHER GUSTS COMBINE  
WITH VERY LOW RELATIVE HUMIDITIES. A CRITICAL RISK OF FIRE DANGER  
IS IN PLACE IN THE STORM PREDICTION CENTER'S FIRE WEATHER OUTLOOK  
FOR THE WEST TEXAS AND SOUTHERN NEW MEXICO ON THURSDAY. RED FLAG  
WARNINGS ARE WIDESPREAD THROUGHOUT THESE AREAS. 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 OVER THE PACIFIC NORTHWEST WILL MOVE  
SOUTHWARD TO NORTHERN MEXICO BY FRIDAY EVENING. THE ENERGY WILL  
INDUCE LOW PRESSURE TO DEVELOP OVER WESTERN TEXAS/NORTHERN MEXICO  
BY SATURDAY. THE SYSTEM WILL PRODUCE RAIN AND HIGHER ELEVATION  
SNOW OVER THE PACIFIC NORTHWEST AND INTERMOUNTAIN REGION THROUGH  
SATURDAY MORNING. FROM THURSDAY INTO FRIDAY, SNOW WILL DEVELOP  
OVER PARTS OF THE GREAT BASIN INTO THE CENTRAL ROCKIES. ON FRIDAY  
INTO SATURDAY, SNOW AND LOWER ELEVATION RAIN WILL DEVELOP OVER  
PARTS OF THE CENTRAL/SOUTHERN ROCKIES AND SOUTHWEST. AS THE  
ENERGY BEGINS TO MOVE ONTO THE SOUTHERN PLAINS, MOISTURE FROM THE  
WESTERN GULF OF MEXICO WILL STREAM NORTHWARD OVER PARTS OF THE  
WESTERN GULF COAST AND THE CENTRAL GULF COAST INTO THE LOWER  
MISSISSIPPI VALLEY ON FRIDAY EVENING INTO SATURDAY. THE MOISTURE  
AND ENERGY WILL DEVELOP SHOWERS AND THUNDERSTORMS OVER THE LOWER  
MISSISSIPPI VALLEY INTO THE SOUTHERN PLAINS ON FRIDAY INTO  
SATURDAY.
