VALID 12Z THU MAR 14 2024 - 12Z SAT MAR 16 2024
...HEAVY SNOW THROUGH TODAY FROM THE CENTRAL ROCKIES, THE
FOOTHILLS, AND NEARBY HIGH PLAINS BEFORE GRADUALLY TAPERING OFF ON
FRIDAY...
...A LONG-DURATION EVENT OF MOUNTAIN SNOW AND LOWER-ELEVATION RAIN
EXPECTED TO DEVELOP OVER THE FOUR CORNERS REGION BEGINNING ON
FRIDAY...
...SEVERE THUNDERSTORMS AND EXCESSIVE RAINFALL EXPECTED TO PUSH
SOUTHWARD FROM THE EAST-CENTRAL PLAINS THIS MORNING TO THE
ARKLATEX REGION ON FRIDAY, AND INTO SOUTHEASTERN TEXAS BY SATURDAY
MORNING...
...VERY MILD/WARM WEATHER EXPANDS EASTWARD FROM THE CENTRAL TO THE
EASTERN U.S. GOING INTO THE WEEKEND...
AN AMPLIFYING UPPER-LEVEL TROUGH CONTINUES TO DIG SOUTHWARD INTO
THE WESTERN U.S. MOISTURE LIFTED AHEAD OF THE UPPER TROUGH WITHIN
A COLD AIR MASS IS PRODUCING HEAVY SNOW ACROSS THE CENTRAL ROCKIES
EARLY THIS MORNING. AS THE COLD AIR CONTINUES TO FILTER
SOUTHWARD, THE RAIN THAT INITIALLY FALLS OVER THE LOWER ELEVATIONS
IS FORECAST TO CHANGE OVER TO HEAVY WET SNOW. THE HEAVIEST SNOW
IS FORECAST TO BE ALONG THE FRONT RANGE OF COLORADO WHERE A FEW
FEET OF SNOW COULD ACCUMULATE. LESSER AMOUNTS ARE EXPECTED IN
ADJACENT AREAS BUT ONE TO TWO FEET OF WET SNOW CAN BE EXPECTED
DOWN INTO THE FOOTHILLS AND HIGH PLAINS SUCH AS BOULDER AND
DENVER, COLORADO. HAZARDOUS TO VERY DIFFICULT TRAVEL IS EXPECTED
AS HEAVY SNOW AND INTENSE SNOW RATES AT TIMES (1-2 INCHES PLUS PER
HOUR) WILL LEAD TO HAZARDOUS TRAVEL CONDITIONS.
BY TONIGHT INTO FRIDAY, THE MAIN UPPER-LEVEL LOW IS FORECAST TO
DIP FURTHER SOUTH INTO THE DESERT SOUTHWEST. SNOW ACROSS THE
CENTRAL ROCKIES/HIGH PLAINS IS EXPECTED TO GRADUALLY TAPER OFF AS
THE DYNAMICS OF THE LOW MOVE FARTHER SOUTH. HOWEVER, THE FOUR
CORNERS REGION WILL BE UNDER THE MOST FAVORABLE REGION FOR
PRECIPITATION TO FORM AND EXPAND BEGINNING ON FRIDAY AS THE UPPER
LOW IS FORECAST TO MEANDER OVER THE REGION. MOUNTAIN SNOW AND
LOWER ELEVATION RAIN ARE EXPECTED TO LINGER OVER THE FOUR CORNERS
REGION GOING INTO THE WEEKEND.
ON THE WARM SIDE OF THE SYSTEM, A LOW PRESSURE SYSTEM IS
DEVELOPING OVER THE CENTRAL PLAINS AND TRACKING TOWARD THE
MIDWEST. INFLUX OF WARM AND MOIST AIR FROM THE GULF OF MEXICO HAS
ORGANIZED STRONG TO SEVERE THUNDERSTORMS AHEAD OF A WARM FRONT.
THESE THUNDERSTORMS CONTAINING HEAVY RAINFALL ARE FORECAST TO PUSH
SOUTHWARD FROM THE EAST-CENTRAL PLAINS THIS MORNING TO THE
ARKLATEX REGION ON FRIDAY, AND INTO SOUTHEASTERN TEXAS BY SATURDAY
MORNING NEAR OR JUST BEHIND AN ADVANCING COLD FRONT. MEANWHILE,
THE LOW PRESSURE SYSTEM WILL BRING WIDESPREAD RAINFALL ACROSS THE
SOUTHERN HALF OF THE GREAT LAKES TODAY, SPREADING INTO NEW ENGLAND
TONIGHT INTO FRIDAY. THE RAIN WILL LIKELY MIX WITH WET SNOW
ACROSS INTERIOR NEW ENGLAND ON FRIDAY BEFORE THE SYSTEM STEADILY
MOVES OFF THE COAST EARLY ON SATURDAY.
AS THE WINTER STORM DEVELOPS OVER THE WESTERN U.S., MUCH OF THE
EASTERN U.S. WILL ENTER AN EXTENDED PERIOD OF VERY WARM AND
PLEASANT WEATHER. HIGH TEMPERATURES IN THE 60S AND 70S FROM THE
OHIO VALLEY TO THE MID-ATLANTIC STATES WILL BE 20-25 DEGREES ABOVE
NORMAL FOR THIS TIME OF
YEAR. HOWEVER, A COLD FRONT FROM CANADA IS FORECAST TO RAPIDLY
DIP INTO THE NORTHERN PLAINS BY EARLY ON SATURDAY. THIS COLD
FRONT WILL SIGNAL THE BEGINNING OF A RAPID COOLING TREND FORECAST
TO HEAD TOWARD THE EAST COAST THEREAFTER.
