UPPER LEVEL TROUGHING WILL REMAIN IN PLACE OVER THE WEST FOR THE

PROVIDING SUPPORT FOR PRECIPITATION ACROSS THE REGION. MOST OF THE
HIGHER ELEVATIONS OF THE REGIONAL MOUNTAIN RANGES WILL SEE SOME
MODERATE TO LOCALLY HEAVY SNOWFALL. THE HIGHEST SNOW AMOUNTS ARE

OR RAIN, AND LIMITED SNOWFALL ACCUMULATIONS WILL BE POSSIBLE IN
SOME AREAS. TEMPERATURES IN THE WEST WILL BE BELOW AVERAGE THROUGH
THE WEEKEND DUE TO FORECAST PRECIPITATION AND CLOUD COVER, THEN
TEMPERATURES WILL RETURN TO NEAR NORMAL NEXT WEEK.
TO THE EAST, A LOW PRESSURE SYSTEM IS SLOWLY MOVING ACROSS THE
UPPER MIDWEST AND WILL CONTINUE ACROSS THE GREAT LAKES ON FRIDAY.
THIS SYSTEM WILL CONTINUE TO PRODUCE WINTRY PRECIPITATION ACROSS

WEST TO EAST EARLY FRIDAY MORNING. AHEAD OF THIS SYSTEM, SHOWERS
AND THUNDERSTORMS WILL SPREAD INTO THE GREAT LAKES REGION AND
ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE FROM EASTERN IOWA
THROUGH SOUTHWESTERN PARTS OF LAKE MICHIGAN. TO THE SOUTH OF THE
TRAILING COLD FRONT ASSOCIATED WITH THIS SYSTEM, STAGNANT
SOUTHERLY FLOW IS FUNNELING MOISTURE FROM THE GULF OF MEXICO INTO
THE SOUTHERN UNITED STATES. WITH AMPLE MOISTURE IN PLACE, SHOWERS
AND THUNDERSTORMS WILL SPREAD FROM THE SOUTHERN PLAINS TO THE
TENNESSEE AND OHIO VALLEYS ON FRIDAY AS THE COLD FRONT APPROACHES
AND PRECIPITATION WILL EXPAND INTO THE MID-ATLANTIC AND NORTHEAST
ON SATURDAY.

THE NATION THROUGH SATURDAY, WITH THE HIGHEST ANOMALIES REACHING

REACH THE 40S AND 50S IN THE UPPER MIDWEST AND GREAT LAKES, AND
THE 60S TO NEAR 70 IN THE MIDDLE MISSISSIPPI VALLEY. THE HIGHEST
