...QUIET AND GENERALLY MILD PATTERN ACROSS THE COUNTRY WILL MEAN
MINIMAL WEATHER-RELATED DISRUPTIONS FOR NEW YEAR'S EVE AND NEW
YEAR'S DAY FESTIVITIES...
...A WEAK CLIPPER-TYPE LOW CENTER WILL BRING A LIGHT WINTRY MIX TO
PARTS OF THE OHIO VALLEY, CENTRAL APPALACHIANS, AND MID-ATLANTIC...
...UNSETTLED WEATHER TO ARRIVE ACROSS CALIFORNIA AND PORTIONS OF
THE SOUTH BY LATE TUESDAY...
LITTLE TO NO PRECIPITATION IS EXPECTED FOR MOST OF THE COUNTRY AS
WE RING IN 2024 TONIGHT AND HEAD THROUGH NEW YEAR'S DAY, AND
TEMPERATURES FOR THIS TIME OF THE YEAR WILL BE RATHER MILD FOR
MANY AREAS GIVEN THE CURRENT PATTERN THAT IS IN PLACE. MUCH OF THE
COLD AIR THAT COULD BE COMING SOUTH INTO THE NATION THIS TIME OF
THE YEAR REMAINS FOCUSED WELL TO THE NORTH ACROSS CANADA, AND THIS
WILL CONTINUE TO RESULT IN A LACK OF WINTRY WEATHER GOING INTO THE
START OF 2024. OVER THE NEXT COUPLE OF DAYS, TEMPERATURES WILL BE
AS MUCH AS 10 TO 20 DEGREES ABOVE AVERAGE FOR PORTIONS OF THE
INTERMOUNTAIN WEST, NORTHERN PLAINS, UPPER MIDWEST, AND THE GREAT
LAKES.
RELATIVELY COOLER TEMPERATURES THOUGH WILL BE NOTED ACROSS AREAS
OF THE OHIO VALLEY, MID-SOUTH AND THE SOUTHERN PLAINS IN BEHIND A
COLD FRONT THAT WILL BE TRAVERSING THIS REGION. A WEAK
CLIPPER-TYPE LOW CENTER ATTACHED TO THIS COLD FRONT WILL BE
CROSSING PARTS OF THE UPPER OHIO VALLEY AND HEADING THROUGH THE
CENTRAL APPALACHIANS THROUGH TONIGHT, AND THEN THE MID-ATLANTIC
REGION ON NEW YEAR'S DAY. JUST ENOUGH COLD AIR WILL BE IN PLACE
FOR THIS WEAK SYSTEM TO PRODUCE A LIGHT WINTRY MIX, AND SOME
ACCUMULATING SNOWFALL IS EXPECTED ACROSS MAINLY THE HIGHER TERRAIN
OF THE CENTRAL APPALACHIANS WHERE A FEW INCHES OF SNOW IS EXPECTED.
BY LATE TUESDAY, THE PATTERN WILL BEGIN TO GRADUALLY BECOME MORE
ACTIVE AS TWO SEPARATE STORM SYSTEMS BEGIN TO IMPACT THE COUNTRY.
ONE WILL BE ACROSS CALIFORNIA AS A PACIFIC COLD FRONT OFFSHORE
APPROACHES THE REGION AND BEGINS TO BRING IN A NEW SURGE OF
MOISTURE ALONG WITH AN AXIS OF MODERATE TO LOCALLY HEAVY RAIN. THE
SECOND AREA OF INTEREST WILL ACROSS PARTS OF THE SOUTH, WITH AN
EMPHASIS ON THE WESTERN GULF COAST REGION AND LOWER MISSISSIPPI
VALLEY, AS LOW PRESSURE ORGANIZING NEAR THE LOWER RIO GRANDE
VALLEY BEGINS TO TAP INTO GULF MOISTURE WHICH WILL ALLOW FOR AREAS
OF MODERATE TO LOCALLY HEAVY RAIN, POSSIBLY A FEW THUNDERSTORMS,
TO DEVELOP AND BEGIN LIFTING NORTHEAST ACROSS THE REGION.
