..SNOW CONTINUES ACROSS THE MID ATLANTIC AND NORTHEAST
...ADDITIONAL FREEZING RAIN AND ELEVATION SNOWFALL EXPECTED OVER
THE PACIFIC NORTHWEST...
...BRIEF REPRIEVE FROM THE BRUTAL COLD AFTER THIS MORNING; ANOTHER
ARCTIC BLAST EXPECTED LATE THIS WEEK...
ONCE AGAIN WINTER WEATHER HEADLINES DOMINATE MUCH OF THE WEATHER
STORY ACROSS THE LOWER 48, WITH CONCURRENT AREAS OF WINTRY
PRECIPITATION ALONG BOTH COASTLINES AND FRIGID ARCTIC AIR
SANDWICHED OVER THE CENTRAL AND SOUTHERN U.S. AFTER PRODUCING
WIDESPREAD SNOW, SLEET, AND FREEZING RAIN OVER THE MID-DEEP SOUTH
THE LAST 24 HOURS, A QUICK MOVING UPPER-TROUGH AND ASSOCIATED
COASTAL-LOW PRESSURE AREA CONTINUES TO SPREAD MODERATE TO HEAVY
SNOWFALL INTO THE MID-ATLANTIC THIS MORNING. WIDESPREAD WINTER
WEATHER ADVISORIES BLANKET THE MID-ATLANTIC INTO NEW ENGLAND,
WHERE MINOR TO LOCALLY MODERATE WINTER WEATHER IMPACTS ARE
POSSIBLE TODAY WHERE AN ADDITIONAL 2-4" CAN BE EXPECTED THROUGH
NEW YORK STATE. AS THE COASTAL LOW DEEPENS THIS AFTERNOON,
MODERATE TO HEAVY SNOWFALL IS EXPECTED IN UPPER NEW ENGLAND
LEADING TO 6-8 INCHES THROUGH TOMORROW. MEANWHILE, HEAVY
LAKE-EFFECT SNOWFALL MAY BRIEFLY SUBSIDE TODAY, BEFORE RENEWING
LATE THIS WEEK WITH WINTER STORM WATCHES HOISTED DOWNWIND OF LAKE
ERIE AND ONTARIO IN NEW YORK.
OVER THE PACIFIC NORTHWEST, OFFSHORE LOW PRESSURE INTERACTING WITH
THE STUBBORN COLD ARCTIC AIRMASS ENTRENCHED ATOP THE REGION WILL
LEAD TO YET ANOTHER EPISODE OF SIGNIFICANT FREEZING RAIN BEGINNING
THIS MORNING, WHICH INCLUDES THE PORTLAND METROPOLITAN AREA. ICE
STORM WARNINGS ARE IN EFFECT THROUGH TOMORROW MORNING AS ONE
QUARTER TO A HALF INCH OF ICE IS EXPECTED. PORTIONS OF THE
CASCADES INTO THE NORTHERN ROCKIES WILL ALSO SEE SIGNIFICANT
IMPACTS FROM THIS STORM IN THE FORM OF SNOW, WITH 15-28 INCHES
POSSIBLE.
ONE MORE DAY OF RECORD BREAKING COLD TEMPERATURES CAN BE EXPECTED
ACROSS MUCH OF THE ROCKIES, GREAT PLAINS, AND MIDWEST TODAY WITH
WIND CHILLS BELOW MINUS 30 EXTENDING INTO THE MID-MISSISSIPPI
VALLEY THIS MORNING. FORTUNATELY, A BRIEF REPRIEVE FROM THE FRIGID
AIR IS EXPECTED AS THE AIRMASS MODERATES BEGINNING WEDNESDAY,
LEADING TO BELOW AVERAGE (BUT NOT BRUTALLY COLD TEMPERATURES) IN
ITS WAKE. UNFORTUNATELY, THE BREAK WILL NOT LAST LONG AS ANOTHER
SURGE OF ARCTIC AIR REACHES THE PLAINS STATES AND DEEP SOUTH BY
THURSDAY-FRIDAY. STAY TUNED AS THE FORECAST CONTINUES TO EVOLVE
WITH THIS UPCOMING SURGE OF COLD AIR.
