A HIGHLY AMPLIFIED UPPER-TROUGH CENTERED NEAR THE OHIO VALLEY WILL
MAINTAIN AN INFLUX OF UNSEASONABLY COLD CONTINENTAL POLAR AIR,
WHICH IS FORECAST TO THREATEN MANY TEMPERATURE RECORDS OVER THE
DEEP SOUTH, LOWER MID-ATLANTIC, AND FLORIDA PENINSULA THROUGH

ADVISORIES EXTEND ACROSS THESE AREAS WHERE TEMPERATURES SHOULD BE
ON AVERAGE 20-30 DEGREES BELOW NORMAL. MEANWHILE, FIRE WEATHER
CONCERNS ACROSS THE SOUTHEAST AND NORTHERN GULF COAST SHOULD WANE
THIS EVENING WITH THE APPROACH OF THE SURFACE HIGH PRESSURE
CENTER, BEFORE SHIFTING INTO THE SOUTHERN PLAINS TOMORROW AMID DRY
DOWNSLOPING WINDS.
THE NORTHWESTERLY FLOW SUPPLYING COLD AIR ACROSS THE MIDWEST AND
INTERIOR NORTHEAST WILL ALSO GENERATE SNOWFALL FOR PORTIONS OF THE
GREAT LAKES AND APPALACHIANS TODAY, WHERE AN ADDITIONAL 4-8" ARE
EXPECTED WITH ISOLATED HIGHER AMOUNTS POSSIBLE BY WEDNESDAY
MORNING. LAKE EFFECT SNOW WARNINGS REMAIN IN EFFECT DOWNWIND OF
LAKE ERIE, WHILE WINTER STORM WARNINGS AND WINTER WEATHER
ADVISORIES DOT DOWNWIND AREAS OF THE GREAT LAKES, NORTHERN MAINE
AND THE CENTRAL/SOUTHERN APPALACHIANS. IN THE WEST, A LOW PRESSURE
SYSTEM IS STILL ON TRACK TO USHER IN AN ATMOSPHERIC RIVER CENTERED
OVER SOUTHERN OREGON AND NORTHERN/CENTRAL CALIFORNIA LATE
WEDNESDAY, ALTHOUGH MUCH OF THE PRECIPITATION LOOKS TO FALL BEYOND
THE FORECAST PERIOD. WHILE FORECAST SPECIFICS WILL BECOME MORE
APPARENT IN THE COMING DAY, USERS ARE ENCOURAGED TO STAY TUNED AS
ISOLATED FLOODING AND HEAVY ELEVATION SNOWFALL ARE POSSIBLE WITH
THIS UPCOMING SYSTEM.
