VALID 12Z TUE NOV 07 2023 - 12Z THU NOV 09 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
UPPER TROUGHING MOVING ACROSS THE NORTHERN TIER WILL BRING
UNSETTLED WEATHER ACROSS THE REGION OVER THE NEXT COUPLE OF DAYS.
AN UPPER TROUGH PROPAGATING THROUGH THE WEST-CENTRAL U.S. WILL
ALLOW FOR THE ADVECTION OF COOL PACIFIC AIR INTO THE WEST OVER THE
NEXT FEW DAYS. IN ADDITION TO THE BELOW AVERAGE TEMPERATURES,
SCATTERED RAIN/SNOW SHOWERS WILL OCCUR FROM THE PACIFIC NORTHWEST
TO THE NORTHERN ROCKIES TODAY. SNOW WILL LIKELY REMAIN CONFINED TO
THE HIGHEST ELEVATIONS OF THE CASCADES AND NORTHERN ROCKIES. HIGH
PRESSURE BUILDS OVER THE WEST ON WEDNESDAY, WHICH SHOULD BRING AN
END TO ANY LINGERING PRECIPITATION.
DIFFLUENCE ASSOCIATED WITH THE AFOREMENTIONED UPPER TROUGH WILL
GENERATE LIGHT MIXED PRECIPITATION FROM THE NORTHERN PLAINS TO THE
NORTHEAST OVER THE NEXT COUPLE OF DAYS. MIXED PRECIP OVER THE
NORTHERN PLAINS TODAY SHOULD SHIFT INTO THE UPPER MIDWEST/GREAT
LAKES TONIGHT BEFORE ARRIVING OVER THE OHIO VALLEY AND LOWER GREAT
LAKES ON WEDNESDAY. BY THURSDAY A DEEP MID-LATITUDE CYCLONE WILL
HAVE DEVELOPED 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.
COOL AIR FILTERS INTO THE UPPER MIDWEST AND NORTHEAST ON THE
BACKSIDE OF THE LOW PRESSURE SYSTEM.
ELSEWHERE, SNOW SHOWERS WILL SPREAD SOUTH ACROSS THE COLORADO
ROCKIES ON WEDNESDAY INTO THURSDAY MORNING. DRY AND WINDY
CONDITIONS OVER THE SOUTHERN HIGH PLAINS OF EASTERN NEW MEXICO
INTO THE TEXAS PANHANDLE WILL SUPPORT A CRITICAL RISK OF FIRES
TODAY. 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.
