...STRONG LOW PRESSURE SYSTEM IS EXPECTED TO PRODUCE A VARIETY OF  
SIGNIFICANT WEATHER IMPACTS ACROSS THE CENTRAL AND EASTERN PART OF  
THE NATION THIS WEEKEND...  
 
THE WEATHER WILL BE QUITE ACTIVE ACROSS A LARGE PART OF THE NATION  
THIS WEEKEND AS A LARGE LOW PRESSURE SYSTEM DEVELOPS AND  
INTENSIFIES ACROSS THE PLAINS AND THEN TRACKS NORTHEASTWARD ACROSS  
THE UPPER MIDWEST AND GREAT LAKES REGION BY SUNDAY MORNING. THIS  
IS IN RESPONSE TO A STRONG UPPER LEVEL SHORTWAVE APPROACHING FROM  
THE ROCKIES EARLY SATURDAY. THE ATMOSPHERIC INGREDIENTS WILL BE  
IN PLACE FOR A MAJOR WINTER STORM FROM NEBRASKA TO WISCONSIN, AND  
THE POTENTIAL EXISTS FOR BLIZZARD CONDITIONS ACROSS MUCH OF THE  
EASTERN DAKOTAS AND CENTRAL MINNESOTA AS THE PRESSURE GRADIENT  
TIGHTENS AND WINDS INCREASE TO OVER 35 MPH. WINTER STORM WARNINGS  
ARE CURRENTLY IN EFFECT FROM SOUTHEAST MONTANA TO WESTERN  
WISCONSIN, AND SOME OF THESE AREAS COULD GET 6 TO 12 INCHES OF  
SNOW WITH LOCALLY HIGHER AMOUNTS.  
 
FARTHER SOUTH AND EAST, HEAVY RAIN AND SEVERE THUNDERSTORMS WILL  
BE MAKING WEATHER HEADLINES AS A WARM AND HUMID AIR MASS SURGES  
NORTHWARD FROM THE GULF OF MEXICO AHEAD OF THE COLD FRONT. THE  
STORMS THAT DEVELOP WILL BECOME CAPABLE OF PRODUCING STRONG WINDS,  
LARGE HAIL AND ALSO SOME TORNADOES FROM THE CENTRAL GULF COAST TO  
THE OHIO VALLEY THROUGH SATURDAY EVENING. ELEVATED FIRE WEATHER  
CONDITIONS WILL ALSO BE PRESENT ACROSS EASTERN NEW MEXICO AND  
WESTERN TEXAS ON SATURDAY WITH DRY AIR AND GUSTY WINDS.  
 
ELSEWHERE, THE EASTERN U.S. WILL GENERALLY BE COOLER THAN NORMAL  
THROUGH SATURDAY, FOLLOWED BY A WARM-UP BY SUNDAY AHEAD OF THE  
STORM SYSTEM APPROACHING FROM THE MIDWEST, BUT ONE EXCEPTION WILL  
BE THE NORTHEAST WHERE HIGH PRESSURE ARRIVING FROM SOUTHEAST  
CANADA WILL KEEP TEMPERATURES NOTABLY COLDER. RAIN IS LIKELY FOR  
PARTS OF CENTRAL AND NORTHERN CALIFORNIA WITH AN OFFSHORE LOW  
PRESSURE SYSTEM TRACKING WEST OF THE REGION.
