VALID 12Z WED FEB 04 2026 - 12Z FRI FEB 06 2026
...A LOW PRESSURE SYSTEM WILL BRING RAIN AND THUNDERSTORMS ACROSS
THE SOUTH AND SOUTHEAST, WITH LIGHT WINTRY PRECIPITATION ACROSS
THE MID-ATLANTIC TODAY...
...PASSAGES OF FRONTAL SYSTEMS WILL BRING PERIODS OF LIGHT TO
LOCALLY MODERATE SNOW FOR THE GREAT LAKES THURSDAY AND INTO
FRIDAY...
...ARCTIC AIR RETURNS TO THE EASTERN U.S. AS A WARM SPELL EXPANDS
ACROSS THE NORTHERN PLAINS TOWARD THE UPPER MIDWEST...
A LOW PRESSURE WAVE TRACKING EAST TOWARD THE SOUTHERN APPALACHIANS
EARLY THIS MORNING HAS DRAWN MOISTURE AND INSTABILITY FROM THE
WARM WATERS OF THE GULF TO SUPPORT WIDESPREAD SHOWERS ACROSS THE
SOUTH AND SOME ORGANIZED THUNDERSTORMS NEAR THE GULF COAST. THE
COLD FRONT TRAILING SOUTHWEST FROM THE LOW PRESSURE CENTER WILL
STEADILY ADVANCE THESE SHOWERS AND EMBEDDED THUNDERSTORMS FROM
WEST TO EAST ACROSS THE GULF COAST THIS MORNING, AND THEN ACROSS
MUCH OF THE SOUTHEAST TODAY INTO TONIGHT. MEANWHILE, A
REPLENISHMENT OF ARCTIC AIR SPREADING INTO THE GREAT LAKES AND THE
NORTHEAST IS SUPPORTING A PERIOD OF LIGHT SNOW ACROSS THE
MID-ATLANTIC EARLY THIS MORNING. THE SNOW SHOULD TAPER OFF BY
DAYBREAK BUT ANOTHER PATCH OF LIGHT SNOW AND WINTRY MIX IS
EXPECTED TO MOVE ACROSS NORTH CAROLINA FROM WEST TO EAST LATER
TODAY THROUGH TONIGHT AS THE LOW PRESSURE WAVE WILL TAKE SOME TIME
TO MOVE THROUGH THE REGION.
BY THURSDAY, THE LOW PRESSURE WAVE IS FORECAST TO MOVE OFF THE
SOUTHEASTERN U.S. AND INTENSIFY RAPIDLY. SHOWERS AND EMBEDDED
THUNDERSTORMS AHEAD OF THE TRAILING COLD FRONT WILL BE MOVING
THROUGH FLORIDA PENINSULA ON THURSDAY. BEHIND THE SYSTEM, MOSTLY
CLEAR SKIES WILL RETURN TO MUCH OF THE EASTERN U.S., ALLOWING
TEMPERATURES TO FALL BACK TO SINGLE DIGITS AND TEENS FROM THE OHIO
VALLEY TO MUCH OF THE NORTHEAST BY THURSDAY MORNING. BY FRIDAY
MORNING, THE COLD AIR WILL MAKE IT ALL THE WAY DOWN THE SUNSHINE
STATE WHERE 30S TO 40S WILL BE COMMON, WITH BELOW FREEZING
TEMPERATURES RETURNING TO THE FLORIDA PANHANDLE.
MEANWHILE, MUCH OF THE WESTERN U.S. WILL REMAIN DRY WITH MILDER
THAN NORMAL CONDITIONS UNDER THE INFLUENCE OF A PERSISTENT
UPPER-LEVEL RIDGE. A SIGNIFICANT WARM UP WILL EMERGE ACROSS THE
NORTHERN HIGH PLAINS TODAY, EXPANDING EAST ACROSS THE NORTHERN
PLAINS TOWARD THE UPPER MIDWEST THROUGH THE NEXT COUPLE OF DAYS.
THIS IS IN RESPONSE TO A STRONGER CLIPPER LOW PRESSURE SYSTEM TO
MOVE ACROSS CENTRAL CANADA. AHEAD OF A WARM FRONT, LIGHT SNOW
WILL BE MOVING INTO THE GREAT LAKES ON THURSDAY, WITH THE ARRIVAL
OF SNOW SHOWERS AND POSSIBLY SNOW SQUALLS OVER THE UPPER GREAT
LAKES BY EARLY ON FRIDAY, SIGNALING THE ARRIVAL OF THE NEXT
INTENSE SURGE FROM ARCTIC AIR FROM CANADA. IN THE MEAN TIME,
RELATIVELY QUIET WEATHER IS EXPECTED FARTHER DOWN THE GREAT PLAINS
WITH A GRADUAL WARMING TREND SPREADING SOUTH INTO TEXAS HEADING
INTO FRIDAY.
