225 AM EST TUE JAN 28 2025
VALID 12Z TUE JAN 28 2025 - 12Z THU JAN 30 2025
...LOCALLY HEAVY SNOW AND SNOW SQUALLS POSSIBLE FOR THE GREAT
LAKES AND NORTHEAST THROUGH WEDNESDAY...
...FLOODING RAIN AND SEVERE THUNDERSTORMS POSSIBLE FROM THE
SOUTHERN PLAINS TO THE MID/LOWER MISSISSIPPI VALLEY WEDNESDAY INTO
THURSDAY...
...WELL ABOVE AVERAGE TEMPERATURES EXPECTED ACROSS MUCH OF THE
CENTRAL AND EASTERN U.S., WHILE BELOW AVERAGE TEMPERATURES LINGER
IN SOUTHERN CALIFORNIA AND THE SOUTHWEST...
A SLOW MOVING LOW PRESSURE SYSTEM WILL GRADUALLY PUSH EAST ACROSS
THE SOUTHWEST AND INTO THE SOUTHERN PLAINS OVER THE NEXT FEW DAYS.
THIS SYSTEM WILL PRODUCE SOME WINTRY WEATHER IN THE FOUR CORNERS
STATES, BUT A LACK OF MOISTURE MAY LIMIT PRECIPITATION AMOUNTS.
THE HEAVIEST SNOW IS EXPECTED LATE TONIGHT THROUGH THURSDAY IN THE
HIGHER ELEVATIONS IN NORTHERN NEW MEXICO AND SOUTHERN COLORADO
WHERE MORE THAN 6 INCHES OF SNOW COULD FALL. AS THE SYSTEM EMERGES
IN THE PLAINS WEDNESDAY INTO THURSDAY, IT WILL TRIGGER WIDESPREAD
SHOWERS AND THUNDERSTORMS FROM THE SOUTHERN PLAINS TO THE
MID/LOWER MISSISSIPPI VALLEY. THERE WILL BE A RISK OF SEVERE
THUNDERSTORMS IN TEXAS, AND POTENTIAL STORM HAZARDS COULD INCLUDE
HAIL AND DAMAGING WIND GUSTS. ISOLATED TO SCATTERED INSTANCES OF
FLASH FLOODING WILL ALSO BE POSSIBLE FROM CENTRAL/NORTH TEXAS TO
THE MID-MISSISSIPPI VALLEY, ESPECIALLY IN URBAN AND POOR DRAINAGE
AREAS AND PLACES WITH TRAINING/REPEAT CONVECTION.
WHILE THE SLOW LOW IMPACTS THE SOUTH-CENTRAL U.S., A SWIFT MOVING
CLIPPER TYPE LOW PRESSURE SYSTEM WILL SWING ACROSS THE GREAT LAKES
AND NORTHEAST, BRINGING WINTRY WEATHER TO THESE REGIONS. A LEADING
COLD FRONT WILL SINK SOUTH ACROSS THE NORTHEAST TODAY, THEN THE
MAIN LOW WILL DIP INTO THE NORTHERN GREAT LAKES TONIGHT, SWING
ACROSS THE NORTHEAST ON WEDNESDAY, AND PUSH OFFSHORE WEDNESDAY
NIGHT. SNOW SQUALLS WILL BE POSSIBLE AS THESE FEATURES MOVE ACROSS
THE GREAT LAKES AND NORTHEAST, WHICH WOULD CREATE INTENSE BURSTS
OF HEAVY SNOWFALL WITH GUSTY WINDS, RESULTING IN LOW VISIBILITY
AND DANGEROUS DRIVING CONDITIONS. MODERATE TO LOCALLY HEAVY SNOW
ACCUMULATIONS ARE EXPECTED FROM THE GREAT LAKES INTO NEW ENGLAND
TODAY THROUGH WEDNESDAY.
TEMPERATURES WILL BE BELOW AVERAGE ACROSS SOUTHERN CALIFORNIA AND
THE SOUTHWEST UNDER THE INFLUENCE OF THE UPPER LOW, AND BELOW
AVERAGE TEMPERATURE ARE ALSO EXPECTED ACROSS PORTIONS OF THE GREAT
LAKES AND NORTHEAST AFTER A COLD FRONT SINKS SOUTH INTO THESE
REGIONS TODAY. SANDWICHED BETWEEN THE SOUTHWEST AND NORTHEAST
CORNERS OF THE NATION, MUCH OF THE CENTRAL AND EASTERN U.S. WILL
EXPERIENCE WELL ABOVE AVERAGE TEMPERATURES THROUGH THURSDAY. THE
HIGHEST ANOMALIES WILL BE IN THE NORTH-CENTRAL U.S. WHERE HIGHS
ARE FORECAST TO BE 15-25 DEGREES ABOVE NORMAL, WHICH COULD
CHALLENGE A FEW DAILY HIGH TEMPERATURE RECORDS IN THE NORTHERN
PLAINS AND UPPER MIDWEST.
