VALID 12Z WED MAR 5 2025 - 12Z FRI MAR 7 2025
...STRONG LOW PRESSURE WITH BLIZZARD CONDITIONS FOR PORTIONS OF
THE UPPER MIDWEST AND GREAT LAKES THROUGH WEDNESDAY NIGHT...
...STRONG TO SEVERE THUNDERSTORMS EXPECTED FROM FLORIDA TO THE
MID-ATLANTIC REGION AHEAD OF A STRONG COLD FRONT...
...RAIN AND MOUNTAIN SNOW RETURNS TO THE WEST COAST AND
INTERMOUNTAIN WEST...
A MAJOR LOW PRESSURE WILL BE MAKING NUMEROUS HEADLINES ACROSS THE
EASTERN U.S. THROUGH THE MIDDLE OF THE WEEK AS THE LOW CENTER
TRACKS FROM THE GREATER CHICAGO METRO AREA TO SOUTHERN MICHIGAN
AND EVENTUALLY OVER SOUTHERN QUEBEC BY THURSDAY AFTERNOON.
BLIZZARD CONDITIONS ARE EXPECTED NORTHWEST OF THE LOW CENTER FROM
NORTH OF KANSAS CITY TO IOWA AND UP TO THE UPPER PENINSULA OF
MICHIGAN, WITH SEVERAL INCHES OF SNOWFALL COMBINED WITH WINDS
GUSTING 40-60 MPH AT TIMES. THIS WILL LEAD TO WHITE-OUT CONDITIONS
AT TIMES, THUS CAUSING HAZARDOUS DRIVING CONDITIONS. CONDITIONS
SHOULD IMPROVE FOR THOSE AREAS BY THURSDAY MORNING AS THE CORE OF
HEAVIEST SNOW MOVES OUT AND WINDS GRADUALLY SUBSIDE.
AREAS TO THE EAST FROM NORTHERN FLORIDA TO NEW ENGLAND WILL HAVE A
BRIEF WARM-UP AHEAD OF THE STRONG COLD FRONT APPROACHING THE EAST
COAST. STRONG SOUTHERLY FLOW AHEAD OF IT WILL LEAD TO WIDESPREAD
HEAVY SHOWERS AND THUNDERSTORMS. THE STORM PREDICTION CENTER IS
EXPECTING THE POTENTIAL FOR SOME SEVERE WEATHER TO DEVELOP FROM
THE MID-ATLANTIC TO NEAR JACKSONVILLE, FLORIDA ON WEDNESDAY, WITH
THE GREATEST THREAT ACROSS THE EASTERN CAROLINAS INTO SOUTHEAST
VIRGINIA WHERE THE BEST COMBINATION OF WIND SHEAR AND INSTABILITY
WILL RESIDE. GIVEN THE OVERALL PROGRESSIVE NATURE OF THE STORM
SYSTEM, RAINFALL TOTALS ARE NOT EXPECTED TO BE EXTREME, BUT SOME
AREAS MAY GET 1 TO LOCALLY 2 INCHES OF RAINFALL BEFORE DRIER
WEATHER COMMENCES BY EARLY THURSDAY.
OUT ACROSS THE WESTERN U.S., THE NEXT STORM SYSTEM WILL BE
ARRIVING ACROSS CALIFORNIA WEDNESDAY AFTERNOON AS AN UPPER LEVEL
TROUGH MOVES IN. THIS WILL LEAD TO INCREASING SHOWERS ACROSS THE
STATE AND HEAVY SNOWFALL FOR THE SIERRA THROUGH THURSDAY NIGHT.
THE MOISTURE ASSOCIATED WITH THIS MOVES INLAND ACROSS THE
INTERMOUNTAIN WEST THROUGH THE DAY THURSDAY, AND REACHING THE
ROCKIES BY THURSDAY NIGHT INTO FRIDAY MORNING. A BAND OF LIGHT TO
MODERATE SNOW IS LIKELY TO DEVELOP ACROSS NEBRASKA AND SOUTHERN
SOUTH DAKOTA BY FRIDAY MORNING AS A NEW SURFACE LOW DEVELOPS
ACROSS THE CENTRAL PLAINS.
ELSEWHERE ACROSS THE NATION, MAINLY DRY CONDITIONS ARE FORECAST
ACROSS THE SOUTH-CENTRAL U.S., WITH FIRE WEATHER CONDITIONS
IMPROVING ACROSS TEXAS ON WEDNESDAY. DRY CONDITIONS ARE ALSO
EXPECTED FROM CENTRAL MONTANA TO NORTHERN MINNESOTA. A WARM DAY
FOR THE EAST COAST ON WEDNESDAY WILL BE FOLLOWED BY A RETURN TO
MORE SEASONAL CONDITIONS ON THURSDAY AFTER THE COLD FRONT MOVES
THROUGH, ALTHOUGH MILD CONDITIONS SHOULD LINGER A LITTLE LONGER
FOR NEW ENGLAND THROUGH LATE THURSDAY. A SHORT RETURN TO BELOW
AVERAGE TEMPERATURES ARE FORECAST TO THE SOUTHEAST U.S. TO CLOSE
OUT THE WORK WEEK BEFORE MILDER CONDITIONS RETURN THIS WEEKEND.
