...ANOTHER DAY OF HEAVY RAIN AND SEVERE WEATHER EXPECTED ACROSS
THE CENTRAL U.S. BEFORE SHIFTING EAST INTO THE ARKLATEX,
MID-MISSISSIPPI VALLEY AND MIDWEST BY MONDAY NIGHT...
...MOUNTAIN SNOW MOVING ACROSS THE INTERMOUNTAIN WEST AND ROCKIES
TODAY WILL BEGIN TO TAPER OFF ON MONDAY AS THE NEXT ROUND OF
MOUNTAIN SNOW AND WIND QUICKLY OVERSPREADS THE PACIFIC NORTHWEST
ON MONDAY...
...ABOVE AVERAGE TEMPERATURES APPROACHING RECORD LEVELS WILL SHIFT
EAST FROM THE PLAINS TODAY TOWARDS THE MISSISSIPPI VALLEY BY
MONDAY WITH NO RAIN IN SIGHT ALONG THE EAST COAST...
THE ONGOING ACTIVE WEATHER SYSTEM OVER THE SOUTH-CENTRAL U.S. WILL
CONTINUE TO TRIGGER ADDITIONAL ROUNDS OF HEAVY RAIN AND SEVERE
WEATHER FOR THE REMAINDER OF TODAY, WITH THE HEAVIEST RAINFALL
EXPECTED TO IMPACT CENTRAL TO EASTERN OKLAHOMA INTO PORTIONS OF
NORTHWESTERN ARKANSAS AND SOUTHERN MISSOURI. MORE ENERGY EJECTING
FROM THE UPPER-LEVEL TROUGH CURRENTLY SPREADING MOUNTAIN SNOW
ACROSS THE INTERMOUNTAIN WEST WILL EVENTUALLY CONSOLIDATE A LOW
PRESSURE SYSTEM OVER THE CENTRAL HIGH PLAINS BY TONIGHT. THIS LOW
PRESSURE SYSTEM WILL TRACK NORTHEASTWARD ACROSS THE CENTRAL PLAINS
FOLLOWED BY ANOTHER LOW PRESSURE SYSTEM TO DEVELOP OVER THE
SOUTH-CENTRAL PLAINS ON MONDAY. THIS SECOND SYSTEM SYSTEM IS
FORECAST TO PUSH A COLD FRONT FARTHER EASTWARD MONDAY NIGHT,
ENDING THE HEAVY RAIN THREAT ACROSS OKLAHOMA BUT SHIFTING THE
HEAVY RAIN AND SEVERE WEATHER THREAT INTO THE ARKLATEX REGION,
MID-MISSISSIPPI VALLEY AND MIDWEST BY MONDAY NIGHT.
THE UPPER TROUGH WILL USHER COLDER THAN NORMAL TEMPERATURES
THROUGH MUCH OF THE WESTERN U.S. FOR THE NEXT COUPLE OF DAYS WITH
MOUNTAIN SNOW PASSING THROUGH THE INTERMOUNTAIN REGION TODAY,
FOLLOWED BY THE CENTRAL AND SOUTHERN ROCKIES ON MONDAY.
MEANWHILE, A RATHER STRONG LOW PRESSURE SYSTEM FROM THE PACIFIC
OCEAN WILL QUICKLY SPREAD THE NEXT ROUND OF COASTAL RAIN INTO THE
PACIFIC NORTHWEST ON MONDAY FOLLOWED BY A GOOD DOSE OF MOUNTAIN
SNOW FARTHER INLAND ALONG WITH QUITE A BIT OF WIND. THE MOUNTAIN
SNOW WILL REACH INTO THE NORTHERN ROCKIES MONDAY NIGHT INTO
TUESDAY MORNING AS THE LOW PRESSURE SYSTEM REDEVELOPS OVER THE
NORTHERN HIGH PLAINS. THE GREATEST CHANCES (>80%) FOR OVER 8
INCHES OF SNOWFALL IN A 24-HOUR PERIOD IS FORECAST OVER THE
NORTHERN CASCADES ON MONDAY. BE SURE TO PREPARE FOR WINTER
DRIVING CONDITIONS IF TRAVELING THROUGHOUT THESE ELEVATED MOUNTAIN
RANGES AND STAY TUNED TO THE LATEST LOCAL WEATHER FORECAST.
WARMER AND MOSTLY DRY CONDITIONS WILL BE FELT EAST OF THE
MISSISSIPPI RIVER THROUGH EARLY NEXT WEEK, BESIDES RAIN CHANCES
ENTERING PARTS OF THE MIDWEST AND GREAT LAKES. A LARGE HIGH
PRESSURE SYSTEM CENTERED OVER THE GREAT LAKES IS FORECAST TO SLIDE
EASTWARD AND OFF THE NEW ENGLAND COASTLINE BY MONDAY, USHERING IN
WARM SOUTHERLY FLOW ON THE WESTERN PERIPHERY. THIS WILL SUPPORT
WIDESPREAD ABOVE AVERAGE HIGH TEMPERATURES INTO THE UPPER 60S AND
70S FROM THE CENTRAL/SOUTHERN PLAINS TO THE MID-ATLANTIC BY
MONDAY, WITH 80S ALONG THE GULF COAST STATES. WHEN COMPARED TO
EARLY NOVEMBER CLIMATOLOGY, THE MIDWEST IS EXPECTED TO EXPERIENCE
TEMPERATURES WELL ABOVE AVERAGE ON MONDAY. THE ANOMALOUS WARMTH
WILL THEN SPREAD ACROSS THE OHIO VALLEY INTO THE GREAT LAKES BY
MONDAY NIGHT INTO EARLY TUESDAY AS SHOWERS AND THUNDERSTORMS AHEAD
OF THE COLD FRONT REACH INTO THE MIDWEST.
