ROCKIES...
...CRITICAL FIRE WEATHER RISK RETURNS TO SOUTHERN HIGH
PLAINS/SOUTHWEST TODAY; EXTREMELY CRITICAL RISK ON THURSDAY...
..SEVERE WEATHER RETURNS TO CENTRAL U.S. BEGINNING THURSDAY
..WELL ABOVE AVERAGE TEMPERATURES OVER THE CENTRAL U.S.
SNOW SHOWERS SHOULD COME TO AN END OVER THE LOWER GREAT LAKES THIS
EVENING WHILE THE ASSOCIATED UPPER-LEVEL LOW SPINS OFF INTO THE
CANADIAN MARITIME. BELOW AVERAGE TEMPERATURES PERSIST THROUGH THIS
EVENING AS SURFACE HIGH PRESSURE SETTLES IN. MEANWHILE, AN
AMPLIFYING UPPER TROUGH WILL PIVOT OVER SOUTHERN CANADA AND SEND A
STRONG COLD FRONT SURGING SOUTHWARD THROUGH THE ROCKIES. MODERATE
TO HEAVY MOUNTAIN SNOW AND STRONG WINDS ARE EXPECTED TO EXPAND
FROM 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 SHIFT
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 UPPER
PATTERN OVER THE FOUR CORNERS WILL SUPPORT THE MIGRATION OF WARM,
WINDY AND VERY DRY CONDITIONS EASTWARD INTO THE SOUTHERN HIGH
PLAINS LATE THIS WEEK. THUS, THE STORM PREDICTION CENTER ISSUED A
SERIES OF CRITICAL TO EXTREMELY CRITICAL FIRE WEATHER OUTLOOKS FOR
THE REGION BEGINNING TODAY AND EXTENDING INTO THE WEEKEND.
THE AFOREMENTIONED AMPLIFYING UPPER TROUGH WILL ALSO PHASE WITH A
SOUTHERN STREAM LOW AND PROMOTE SCATTERED TO SEVERE THUNDERSTORM
ACTIVITY ACROSS THE CENTRAL U.S. BEGINNING TONIGHT. ISOLATED TO
SEVERE STORMS CAPABLE OF PRODUCING LARGE TO VERY LARGE HAIL, A
COUPLE TORNADOES AND LOCALIZED DAMAGING WINDS MAY OCCUR, ACCORDING
TO THE STORM PREDICTION CENTER'S SLIGHT RISK AREA CENTERED OVER
THE CORN BELT STATES FOR THURSDAY. THE COLD FRONT ASSOCIATED WITH
THIS ACTIVITY WILL BECOME THE FOCUS FOR ADDITIONAL SEVERE WEATHER
AND EXCESSIVE RAINFALL CONCERNS EXTENDING FROM THE UPPER GREAT
LAKES TO THE SOUTHERN PLAINS THROUGH THE WEEKEND.
