...INCREASING PRECIPITATION CHANCES, INCLUDING MOUNTAIN SNOW, AS
WELL AS MUCH COOLER TEMPERATURES AND GUSTY WINDS FOR THE WEST TO
START THE WEEK...
...MUCH ABOVE AVERAGE, RECORD-TYING/BREAKING WARMTH FOR PORTIONS
OF THE PLAINS AND MIDWEST THROUGH MIDWEEK...
..SHOWERS AND THUNDERSTORMS FOR THE GREAT LAKES TUESDAY
A DEEPENING UPPER-LEVEL TROUGH AND ACCOMPANYING SURFACE COLD FRONT
WILL CONTINUE SOUTHEASTWARD ACROSS THE NORTHWEST TODAY (SUNDAY),
SPREADING INCREASING PRECIPITATION CHANCES, COOLER TEMPERATURES,
AND GUSTY WINDS THROUGHOUT THE WEST OVER THE NEXT COUPLE OF DAYS.
SHOWERS AND THUNDERSTORMS PRODUCING HEAVY RAINFALL IN THE PACIFIC
NORTHWEST TODAY WILL REMAIN POSSIBLE SUNDAY NIGHT INTO MONDAY
BEFORE BEGINNING TO WANE LATER MONDAY EVENING. LOWER
ELEVATION/VALLEY RAIN AND HIGHER ELEVATION MOUNTAIN SNOW WILL
SPREAD INLAND FROM THE NORTHWEST INTO THE NORTHERN ROCKIES AND
GREAT BASIN MONDAY AND THE CENTRAL ROCKIES BY EARLY TUESDAY. THE
LOWER ELEVATION RAINS WILL MAINLY REMAIN LIGHT TO MODERATE, BUT
SOME LOCALLY HEAVY SNOWFALL WILL BE POSSIBLE FOR THE HIGHER
ELEVATION MOUNTAINS, PARTICULARLY FROM THE EASTERN GREAT BASIN
INTO THE CENTRAL ROCKIES ON TUESDAY. SNOWFALL TOTALS OF 6-12" WILL
BE POSSIBLE. HIGHER ELEVATIONS OF THE BLACK HILLS MAY ALSO SEE
SOME HEAVIER SNOWFALL TOTALS OF 4-8". A TRANSITION TO SOME SNOW
LATER TUESDAY LOOKS POSSIBLE FOR AREAS OF THE HIGH PLAINS ALONG
THE FRONT RANGE OF THE ROCKIES, BUT TIMING AND ANY POTENTIAL
ACCUMULATION REMAINS UNCERTAIN AT THIS TIME. MUCH COOLER
TEMPERATURES WILL ALSO FOLLOW BEHIND THE COLD FRONT AS IT PUSHES
EASTWARD THROUGH THE WEST. HIGHS ON MONDAY WILL FALL INTO THE 50S
FOR MOST OF THE PACIFIC NORTHWEST, NORTHERN GREAT BASIN, AND
NORTHERN ROCKIES, WITH HIGHS ONLY REACHING INTO THE 40S BY TUESDAY
ACROSS THE ENTIRE GREAT BASIN AND INTO THE NORTHERN ROCKIES. HIGHS
WILL ALSO FALL INTO THE 70S ACROSS THE SOUTHWEST BY TUESDAY AFTER
A HOT SUNDAY THAT SAW HIGHS INTO THE 90S FOR MANY LOCATIONS. GUSTY
WINDS ARE EXPECTED AS WELL, ESPECIALLY ACROSS SOUTHERN CALIFORNIA,
THE SOUTHWEST, AND INTO THE CENTRAL/SOUTHERN ROCKIES MONDAY, AND
THE CENTRAL/SOUTHERN PLAINS MONDAY INTO TUESDAY. THE STORM
PREDICTION CENTER HAS NOTED AN ELEVATED RISK OF FIRE WEATHER
(LEVEL 1/3) ACROSS MUCH OF THIS REGION MONDAY.
MEANWHILE, MUCH ABOVE AVERAGE, RECORD WARMTH FOR LATE OCTOBER IS
EXPECTED FOR THE PLAINS AND MIDWEST AS A BROAD RIDGE OF HIGH
PRESSURE BUILDS NORTHWARD AHEAD OF THE DEEP UPPER-LEVEL SYSTEM IN
THE WEST. FORECAST HIGHS ARE IN THE 70S AND 80S FOR THE NORTHERN
PLAINS AND MIDWEST AND 80S TO LOW 90S FOR THE CENTRAL/SOUTHERN
PLAINS. NUMEROUS, WIDESPREAD RECORD-TYING/BREAKING HIGH
TEMPERATURES WILL BE POSSIBLE. HOWEVER, THESE TEMPERATURES WON'T
LAST FOR LONG FOR MORE NORTHERN LOCATIONS AS THE COLD FRONT IN THE
WEST QUICKLY PUSHES OUT INTO THE NORTHERN PLAINS TUESDAY, WITH
HIGHS BEHIND THE FRONT DROPPING INTO THE 50S. WHILE NOT QUITE AS
ABNORMAL, TEMPERATURES WILL ALSO WARM AFTER A COOLER SUNDAY ALONG
THE EAST COAST, INCLUDING SOME POSSIBLE FREEZING TEMPERATURES FOR
PORTIONS OF THE MID-ATLANTIC SUNDAY NIGHT. HIGHS MONDAY-TUESDAY
WILL RISE INTO THE 60S AND 70S FOR THE MID-ATLANTIC AND CAROLINAS
AND THE 50S AND 60S IN NEW ENGLAND. WHILE MUCH OF THE REST OF THE
COUNTRY WILL BE DRY OUTSIDE OF THE WEST, STORM CHANCES WILL BEGIN
TO INCREASE FOR THE GREAT LAKES AS MOISTURE INCREASES WITH A WARM
FRONT LIFTING NORTHWARD THROUGH THE REGION ON TUESDAY. SOME
SHOWERS AND THUNDERSTORMS ARE ALSO POSSIBLE ALONG AND BEHIND THE
COLD FRONT PUSHING THROUGH THE NORTHERN PLAINS BY LATER TUESDAY
AFTERNOON/EVENING.
