...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 BECOME VERY ACTIVE ACROSS A LARGE PART OF THE  
NATION THIS WEEKEND AS A STRONG LOW PRESSURE SYSTEM IS FORECAST TO  
TRACK ACROSS PLAINS TOWARD THE GREAT LAKES. THE PRIMARY FOCUS  
INITIALLY WILL BE ACROSS THE WEST AS THE STORM SYSTEM CONSOLIDATES  
AND BRINGS RATHER WIDESPREAD RAIN AND SNOW ACROSS PORTIONS OF THE  
PACIFIC NORTHWEST, THE GREAT BASIN AND INTO THE ROCKIES. AS A  
STRONG UPPER LEVEL SHORTWAVE APPROACHES FROM THE WEST, A LOW  
PRESSURE SYSTEM IS FORECAST TO RAPIDLY INTENSIFY AS IT MOVES  
EAST-NORTHEAST ACROSS THE CENTRAL PLAINS ON 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. TOTAL SNOWFALL IS EXPECTED TO RANGE FROM 4 INCHES  
ACROSS THE NORTHERN HIGH PLAINS, INCREASING TO A FOOT POSSIBLE  
OVER WESTERN MINNESOTA.  
 
FARTHER SOUTH AND EAST, RAIN COULD BE HEAVY, ALONG WITH A GOOD  
CHANCE OF SEVERE THUNDERSTORMS AS A STRONG COLD FRONT SWEEPS  
ACROSS THE PLAINS ON SATURDAY, PASSING EAST OF THE MISSISSIPPI  
VALLEY SATURDAY NIGHT. BY SUNDAY MORNING, MUCH OF THE RAIN SHOULD  
BE MORE FOCUSED FARTHER TO THE NORTHEAST ACROSS THE CENTRAL  
APPALACHIANS AND INTO THE NORTHERN MID-ATLANTIC. NEW ENGLAND  
SHOULD SEE SNOW MOVING IN AND QUICKLY CHANGE OVER TO MIXED  
PRECIPITATION OR EVEN PLAIN RAIN AS THE STORM CENTER TRACKS WELL  
TO THE NORTH INTO CANADA. SOME THUNDERSTORMS CAN BE EXPECTED  
ACROSS THE SOUTHEAST AND NEAR THE GULF COAST AHEAD OF THE COLD  
FRONTS BUT THE STORMS ARE EXPECTED TO BE LESS SEVERE.  
 
MEANWHILE, ANOTHER PACIFIC CYCLONE IS FORECAST TO SKIRT THE  
CALIFORNIA COAST FROM NORTH TO SOUTH THROUGH THE WEEKEND. SOME  
RAIN IS EXPECTED TO SPREAD ACROSS CALIFORNIA WHILE SNOW IS  
EXPECTED FOR THE SIERRA NEVADA AND INTO THE GREAT BASIN.
