...MAJOR WINTER STORM SET TO BEGIN IN THE SOUTHEAST AND
MID-ATLANTIC ON FRIDAY...
...PRECIPITATION CONTINUES IN THE PACIFIC NORTHWEST AND
INTERMOUNTAIN WEST...
...FRIGID TEMPERATURES ARE SET TO CONTINUE THROUGHOUT MUCH OF THE
EASTERN UNITED STATES THROUGH THE WEEKEND...
A LOW PRESSURE SYSTEM FORMING IN THE SOUTHERN PLAINS IS FORECAST
TO PROGRESS THROUGH THE GULF COAST AND INTO THE SOUTHEAST BY
FRIDAY. THIS IS EXPECTED TO PRODUCE A MAJOR WINTER STORM FOR
PORTIONS OF THE MID-ATLANTIC AND SOUTHEAST, INCLUDING THE
CAROLINAS, SOUTHERN VIRGINIA, AND THE CHESAPEAKE BAY REGION. BY
FRIDAY EVENING/SATURDAY MORNING, THE LOW WILL MOVE OFFSHORE INTO
THE ATLANTIC AND TRAVERSE NORTHEASTWARD, WHERE IT IS EXPECTED TO
CONTINUE BRINGING SNOW INTO THE MID-ATLANTIC. THIS SYSTEM IS ALSO
EXPECTED TO BRING STRONG FLOW ONSHORE INTO THE EAST COAST. WHERE
THE WINDS OVERLAP WITH SNOWFALL, BLOWING SNOW AND SIGNIFICANTLY
REDUCED VISIBILITY ARE EXPECTED, CREATING DANGEROUS, NEAR-BLIZZARD
CONDITIONS ACROSS NORTHEAST NORTH CAROLINA AND SOUTHEAST VIRGINIA.
ADDITIONALLY, STRONG WINDS COMBINED WITH HIGH TIDES COULD PRODUCE
LOCALLY SIGNIFICANT COASTAL FLOODING AND DAMAGING WAVES.
IN THE PACIFIC NORTHWEST, PRECIPITATION IN THE FORM OF RAIN IN THE
COASTAL REGIONS, AND SNOW/MIXED PRECIPITATION IN UPSLOPE REGIONS
IS EXPECTED TO CONTINUE FOR THE NEXT FEW DAYS. A SET OF
UPPER-LEVEL TROUGHS INTRUDING INTO THE REGION WILL AID IN
GENERATING VARIOUS SURFACE LEVEL FRONTAL SYSTEMS WHICH ARE
FORECAST TO APPROACH THE COAST. THESE SYSTEMS WILL BRING ABOVE
AVERAGE MOISTURE CONTENT, AND COMBINED WITH STRONG ONSHORE FLOW,
HEAVY PRECIPITATION IS EXPECTED IN UPSLOPE REGIONS OF NORTHWEST
WASHINGTON AND THE COASTAL REGIONS OF OREGON. FARTHER DOWNWIND, IN
THE INTERMOUNTAIN WEST REGION, THE HIGHER ELEVATION REGIONS IN THE
MOUNTAINS WILL ALSO EXPERIENCE UPSLOPE WESTERLY FLOW, BRINGING
SNOW AND MIXED PRECIPITATION TO PARTS OF IDAHO, MONTANA, AND
WYOMING. MEANWHILE IN THE NORTHERN PLAINS, A PERSISTENT STATIONARY
BOUNDARY WILL BRING SNOWFALL TO THE DAKOTAS AND NEBRASKA THROUGH
FRIDAY EVENING.
IN THE EASTERN UNITED STATES, A POWERFUL ARCTIC BLAST IS SET TO
MOVE SOUTH FROM THE NORTHERN PLAINS, REACHING THE GULF COAST BY
FRIDAY EVENING. NUMEROUS DAILY RECORD LOW TEMPERATURES ARE
EXPECTED THROUGHOUT PORTIONS OF THE UPPER OHIO VALLEY AND
MID-ATLANTIC. DANGEROUSLY COLD TEMPERATURES AND RECORD LOW
TEMPERATURES ARE THEN EXPECTED TO REACH THE SOUTHEAST THIS
WEEKEND. WITH THE FORMATION OF THE AFOREMENTIONED WINTER STORM,
STRONG GUSTY WINDS WILL BRING EXTREMELY COLD WIND CHILLS,
INCLUDING SUB-ZERO VALUES, OVER MUCH OF THE SOUTH. CONTINUE TO
COVER UP IF YOU ARE OUTSIDE, ENSURE THAT PETS AND ANIMALS HAVE
PROTECTION FROM THE COLD, AND CONTINUE TO TAKE STEPS TO PREVENT
FROZEN PIPES.
