VALID 00Z WED NOV 08 2023 - 00Z FRI NOV 10 2023
...COOLER TEMPERATURES AND BENEFICIAL PRECIPITATION EXPECTED
THROUGH MIDWEEK ACROSS THE NORTHERN TIER STATES...
...VERY WARM WEATHER INCLUDING SOME RECORD HIGH TEMPERATURES CAN
BE EXPECTED ALONG WITH DRY CONDITIONS FOR MUCH OF THE CENTRAL AND
EASTERN U.S. THROUGH THE MIDDLE OF THE WEEK...
..SOME RAIN TO BEGIN IMPACTING PARTS OF THE SOUTH BY THURSDAY
AN UPPER LEVEL TROUGH ADVANCING EASTWARD ACROSS THE NORTHERN TIER
STATES WILL KEEP UNSETTLED CONDITIONS IN STORE FOR THE NEXT FEW
DAYS. AS THE UPPER TROUGH MOVES THROUGH THE WEST-CENTRAL PORTIONS
OF THE COUNTRY COOL PACIFIC MOISTURE WILL ADVECT INTO THE WEST
RESULTING IN BELOW SEASONAL NORMAL TEMPERATURES ALONG WITH
SCATTERED RAIN/SNOW SHOWERS FOR THE PACIFIC NORTHWEST AND NORTHERN
ROCKIES. THE SNOW LIKELY REMAIN CONFINED TO THE HIGHEST ELEVATIONS
OF THE CASCADES AND NORTHERN ROCKIES. IN ITS WAKE HIGH PRESSURE
WILL BUILD OVER THE WEST WEDNESDAY AND THURSDAY WHILE LINGERING
PRECIPITATION TAPERS OFF.
DIFFLUENCE ASSOCIATED WITH THE AFOREMENTIONED UPPER TROUGH WILL
GENERATE LIGHT MIXED PRECIPITATION FROM THE NORTHERN PLAINS TO THE
NORTHEAST THROUGH THE END OF THE WEEK. A DEEP MID-LATITUDE CYCLONE
WILL HAVE DEVELOPED BY THURSDAY OVER THE MIDWEST AND WILL SPREAD
SHOWERS AND ISOLATED THUNDERSTORMS INTO THE INTERIOR NORTHEAST.
SHOWERS AND THUNDERSTORMS WILL ALSO DEVELOP ALONG THE ATTENDANT
COLD FRONT OVER THE SOUTHERN PLAINS AND LOWER MISSISSIPPI VALLEY
BY THEN. COOLER AIR WILL FILTER INTO THE UPPER MIDWEST, GREAT
LAKES AND THE NORTHEAST ON THE BACKSIDE OF THE LOW PRESSURE
SYSTEM. MEANWHILE, SNOW SHOWERS WILL SPREAD SOUTH ACROSS THE
COLORADO ROCKIES ON WEDNESDAY INTO THURSDAY MORNING. THERE IS A
CRITICAL RISK FOR WILDFIRES TODAY GIVEN THE THE DRY AND WINDY
CONDITIONS OVER THE SOUTHERN HIGH PLAINS OF EASTERN NEW MEXICO
INTO THE TEXAS PANHANDLE. SOUTHERLY FLOW ACROSS THE CENTRAL AND
SOUTHEASTERN U.S. WILL PRODUCE ANOMALOUS WARMTH FOR MUCH OF THE
GREAT PLAINS TO THE EAST COAST BEFORE THE COLD FRONT SWEEPS
THROUGH ON THURSDAY. MANY PLACES FROM THE SOUTHERN PLAINS TO THE
CENTRAL/SOUTHERN APPALACHIANS MAY EXPERIENCE RECORD HIGH
TEMPERATURES TODAY AND WEDNESDAY.
