A SNAPSHOT OF OUR WEATHER PATTERN ACROSS THE LOWER 48 TONIGHT
DEPICTS A SERIES OF SHORTWAVE TROUGHS NEAR THE NATION'S
MIDSECTION, WITH AN UPPER-RIDGE LOCATED OVER THE EASTERN SEABOARD.
AT THE SURFACE, A STRONG COLORADO LOW IS FORECAST TO LIFT FROM THE
UPPER MIDWEST INTO NORTHEAST CANADA TODAY, PULLING A COLD FRONT
SOUTHWARD ACROSS THE HIGH PLAINS TO THE OHIO VALLEY. UPSLOPE FLOW
FROM THIS FRONT COMBINED WITH A SLUG OF PACIFIC MOISTURE WILL LEAD
TO 6-8" OF SNOWFALL ACROSS THE CENTRAL/SOUTHERN HIGH PLAINS TODAY,
WHERE A SWATH OF WINTER STORM WARNINGS ARE IN EFFECT. MEANWHILE,
IN THE LOWER MISSISSIPPI VALLEY AND SOUTHEAST, A CURRENT OF WARM
AND UNSTABLE AIR CONTINUES TO MIGRATE NORTHWARD AHEAD OF THE COLD
FRONT. AS THE FRONT STALLS OUT OVER THE REGION TODAY, NUMEROUS
INSTANCES OF FLASH FLOODING ARE EXPECTED OVER PORTIONS OF SOUTHERN
MISSISSIPPI AND ADJACENT LOUISIANA AS THUNDERSTORMS TRAIN AND
REPEAT, POTENTIALLY LEADING TO 5-8" OF RAINFALL WHEN ALL IS SAID
AND DONE. A FEW TORNADOES, WIND. AND HAIL ARE ALSO EXPECTED WITH
THESE THUNDERSTORMS PER THE LATEST STORM PREDICTION CENTER
FORECAST. BY SATURDAY AND SUNDAY, THE FRONT IS FORECAST TO MIGRATE
INTO THE MID-ATLANTIC, USHERING IN WIDESPREAD (BUT BENIGN)
RAINFALL TO THE REGION. POCKETS OF FREEZING RAIN AND ELEVATION
SNOWS REMAIN POSSIBLE OVER PORTIONS OF NEW ENGLAND WITH THIS
UPCOMING ROUND, HOWEVER.
