...TURNING MUCH COLDER FOR THE NORTHERN PLAINS AND UPPER MIDWEST
BY SATURDAY...
...SOME STRONG TO SEVERE THUNDERSTORMS POSSIBLE FROM THE GULF
COAST TO THE OHIO VALLEY ON FRIDAY...
...REMAINING DRY FROM THE DESERT SOUTHWEST TO THE SOUTHERN
PLAINS...
A SIGNIFICANT CHANGE IN THE WEATHER PATTERN IS EXPECTED ACROSS THE
U.S. OVER THE NEXT FEW DAYS. A SERIES OF UPPER-LEVEL TROUGHS WILL
MOVE EASTWARD ACROSS THE COUNTRY, WITH A MUCH STRONGER TROUGH
DEVELOPING OVER THE GREAT LAKES AND UPPER MIDWEST BY THIS WEEKEND.
THIS WILL USHER IN A MUCH COLDER AIR MASS IN TIME FOR THE WEEKEND,
PARTICULARLY FOR THE NORTHERN PLAINS AND UPPER MIDWEST BRINGING IN
THE COLDEST AIR OF THE SEASON THUS FAR, WITH AFTERNOON HIGHS
LIKELY REMAINING BELOW FREEZING ACROSS PORTIONS OF THE DAKOTAS AND
NORTHERN MINNESOTA BY SATURDAY.
FOR THE PACIFIC NORTHWEST, AN ATMOSPHERIC RIVER WILL PRODUCE RAIN,
ALONG WITH HEAVY SNOW IN THE HIGHER ELEVATIONS OF THE CASCADES
THROUGH EARLY FRIDAY. THE STORM SYSTEM WILL THEN MOVE EASTWARD
OVER THE NORTHERN ROCKIES. THIS WILL LIKELY RESULT IN MODERATE TO
HEAVY SNOW FOR THE HIGHER ELEVATIONS OF MONTANA AND WYOMING.
CONDITIONS IMPROVE BY FRIDAY NIGHT AND INTO SATURDAY WITH DRIER
WEATHER RETURNING.
ACROSS THE NORTHEAST AND MID-ATLANTIC, AN UPPER-LEVEL TROUGH WILL
INTENSIFY OVER THE GREAT LAKES AND MOVE EAST. A COLD FRONT
ASSOCIATED WITH THIS SYSTEM WILL APPROACH LATE FRIDAY, BRINGING A
CHANCE OF SHOWERS ALONG AND AHEAD OF IT FOR THE NORTHEAST. THERE
SHOULD BE ENOUGH INSTABILITY AND UPPER LEVEL DYNAMICS IN PLACE FOR
SOME STRONG TO SEVERE THUNDERSTORMS TO DEVELOP FROM THE DEEP SOUTH
TO THE OHIO VALLEY ON FRIDAY, WITH THE HIGHEST CHANCES OF THIS
ACROSS CENTRAL TENNESSEE AND INTO KENTUCKY. THE FRONT WILL MOVE
THROUGH THE REGION OVERNIGHT INTO SATURDAY, BUT STILL REMAINING
PLEASANT OVERALL FOR SATURDAY AHEAD OF THE MUCH STRONGER COLD
FRONT LATE SUNDAY.
ELSEWHERE ACROSS THE NATION, DRY CONDITIONS ARE EXPECTED TO
CONTINUE FROM CENTRAL/SOUTHERN CALIFORNIA EASTWARD TO ARKANSAS AND
WESTERN LOUISIANA, WITH TEMPERATURES GENERALLY RUNNING ABOVE
NORMAL FOR THIS TIME OF YEAR AS THE INFLUENCE OF THE COLD FRONTS
STAYS TO THE NORTH THROUGH THIS FORECAST PERIOD, AND TURNING
COLDER ACROSS THE SOUTHERN PLAINS BY SUNDAY AS THE COLD CANADIAN
HIGH DROPS FARTHER SOUTH.
