SNOW SHOWERS SHOULD COME TO AN END OVER THE LOWER GREAT LAKES THIS

THE MONTANA RANGES TODAY INTO NORTHWESTERN WYOMING ON THURSDAY,
FOLLOWED BY COLORADO BY FRIDAY. THE HEAVIEST SNOWFALL TOTALS ARE
LIKELY OVER PORTIONS OF SOUTHERN MONTANA INTO WYOMING WHERE 1-2
FEET, ISOLATED HIGHER AMOUNTS, ARE PROBABLE BY THURSDAY MORNING.
WIDESPREAD MODERATE TO ISOLATED MAJOR IMPACTS ARE EXPECTED FROM
THE COMBINATION OF SNOW AND WIND. COOLER AIR FILTERS INTO THE
ROCKIES AND INTERMOUNTAIN WEST BEHIND THE COLD FRONT, LEADING TO
WELL BELOW AVERAGE TEMPERATURES FOR THE REGION LATE THIS WEEK.
AN UPPER RIDGE OVER THE CENTRAL U.S. WILL CONTINUE TO STREAM WARM
SOUTHERLY AIR INTO THE GREAT PLAINS TODAY AND GRADUALLY SHIFTING
EASTWARD OVER THE NEXT FEW DAYS. TEMPERATURES IN THE 80S AND 90S
WILL REPRESENT 20-30 DEGREE WARM ANOMALIES OVER PARTS OF THE
CENTRAL/SOUTHERN PLAINS FOR THIS TIME OF YEAR. AN AMPLIFYING
PATTERN OVER THE FOUR CORNERS WILL SUPPORT A MIGRATION OF VERY DRY
CONDITIONS EASTWARD INTO THE SOUTHERN HIGH PLAINS LATE THIS WEEK.
