SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
221 AM EST SAT JAN 10 2026
VALID 12Z SAT JAN 10 2026 - 12Z MON JAN 12 2026
...LINGERING HEAVY RAINFALL AND SEVERE WEATHER OVER PARTS OF THE
SOUTHERN APPALACHIANS AND SOUTHEAST TODAY...
...WINTRY WEATHER TO SPREAD FROM THE NORTHERN GREAT LAKES INTO NEW
ENGLAND...
A SNAPSHOT OF THE WEATHER PATTERN TONIGHT SHOWS A PAIR OF LOW
PRESSURE CENTERS WHICH WILL DRIVE MUCH OF OUR INTERESTING WEATHER
FOR THE NEXT TWO DAYS, INCLUDING A CLIPPER ALONG THE NORTHERN TIER
AND A SOUTHERN LOW NEAR THE GULF COAST. THE SOUTHERNMOST LOW AND
ASSOCIATED COLD FRONT CONTINUES TO DRIVE FLASH FLOODING AND SEVERE
WEATHER ACROSS THE SOUTHEAST AS IT INTERACTS WITH A VERY WARM AND
UNSTABLE PRE-FRONTAL AIRMASS. THROUGH THIS MORNING, NUMEROUS
INSTANCES OF FLASH FLOODING AND SCATTERED SEVERE WEATHER REMAIN
POSSIBLE OVER PORTIONS OF THE LOWER MISSISSIPPI VALLEY AND GULF
STATES AS ADDITIONAL THUNDERSTORM COMPLEXES FORM. FORTUNATELY, THE
THREAT OF EXCESSIVE RAINFALL WILL DECREASE WITH THE FRONTAL
PASSAGE BEYOND THIS MORNING, ALTHOUGH AN ISOLATED FLASH FLOOD CAN
NOT BE RULED OUT IN THE SOUTHERN APPALACHIANS TODAY. ADJACENT
AREAS ACROSS OF THE MID-ATLANTIC AND TENNESSEE VALLEY CAN EXPECT
A WASHOUT TODAY AS STEADY (BUT BENIGN) RAIN OVERSPREADS THE
REGION.
AT THE SAME TIME, WINTRY WEATHER IS EXPECTED TO INCREASE OVER THE
NORTHERN GREAT LAKES AND UPPER MIDWEST AS COLD AIR PROVIDED BY THE
CLIPPER MINGLES WITH AN INFLUX OF MOISTURE FROM THE GULF LOW.
MODERATE TO LOCALLY HEAVY SNOWFALL IS FORECAST TO OVERSPREAD THE
NORTHERN GREAT LAKES THIS MORNING AND CONTINUE THROUGH THE DAY,
LEADING TO 4-6" DOWNWIND OF LAKE MICHIGAN AND ATOP THE UPPER
PENINSULA. BY TOMORROW AFTERNOON, ONE DOMINANT LOW IS EXPECTED TO
EMERGE NEAR LAKE ERIE, WHILE A WINTRY MIX FORMS OVER THE INTERIOR
NORTHEAST AND NEW ENGLAND. FREEZING RAIN REMAINS THE BIGGEST
HAZARD WITH THIS MIX WITH COLD AIR DAMMING IN PLACE, AND SOME
AREAS IN EASTERN NEW YORK, VERMONT, AND WESTERN MASSACHUSETTS
COULD MEASURE A TENTH OF AN INCH THROUGH SUNDAY.
TEMPERATURE WISE, THE PASSAGE OF A COLD FRONT ON SUNDAY WILL
INTERRUPT THE UNSEASONABLY MILD WEATHER THE EASTERN U.S. HAS SEEN
FOR THE LAST FEW DAYS, BRINGING IN HIGHS BACK DOWN TO THE 30'S AND
40'S. IN CONTRAST, MUCH ABOVE NORMAL WARMTH CAN BE FOUND OVER THE
NORTHERN AND CENTRAL PLAINS AS WARM AIR DESCENDS THE ROCKIES,
LEADING TO HIGHS WHICH RANGE FROM THE 40'S-60'S.
