...ARCTIC AIR DESCENDING INTO THE PLAINS TODAY WILL BE FOLLOWED BY
A POTENT WINTER STORM FROM THE UPPER MIDWEST TO THE GREAT LAKES
TODAY INTO MONDAY...
...RECORD WARMTH ACROSS THE CENTRAL AND SOUTHERN U.S. THIS MORNING
WILL BE DRASTICALLY DISPELLED BY ARCTIC WIND CHILLS TONIGHT...
OVER THE NEXT 48 HOURS, AN INTENSE CYCLONE WILL TAKE THE CENTER
STAGE WITH IMPACTS FROM THIS SYSTEM RANGING FROM HEAVY SNOW AND
BLIZZARD CONDITIONS ACROSS THE UPPER MIDWEST TO THE GREAT LAKES,
FREEZING RAIN ACROSS NEW ENGLAND, THUNDERSTORMS THROUGH THE
EASTERN U.S. AND THE SOUTH, AS WELL AS WIDESPREAD BLUSTERY WINDS
TO LOCALLY DAMAGING WINDS TO THESE AREAS. A LOW PRESSURE SYSTEM IS
RAPIDLY DEVELOPING OVER THE MID-MISSISSIPPI VALLEY ALONG AN ARCTIC
FRONT AS THE INCOMING FRIGID AIR FROM CANADA MINGLES WITH THE
ANOMALOUS WARM AIRMASS THAT HAS SETTLED ACROSS THE
CENTRAL/SOUTHERN U.S. FOR MANY DAYS. AS THE SYSTEM ACCELERATES
NORTHEASTWARD TODAY, HEAVY SNOW AND BLIZZARD CONDITIONS WILL
CONTINUE ACROSS THE UPPER MIDWEST AND THE GREAT LAKES THROUGH
TOMORROW. MEANWHILE, FREEZING RAIN AHEAD OF A WARM FRONT IS
FORECAST TO EXPAND ACROSS THE NORTHEAST BEFORE MOVING EASTWARD
THROUGH INTERIOR NEW ENGLAND TONIGHT. BY MONDAY MORNING, A MIX OF
SNOW SLEET AND FREEZING RAIN WILL LIKELY IMPACT NORTHERN NEW
ENGLAND BEFORE WARMER AIR CHANGES THE WINTRY MIX TO ALL RAIN LATER
ON MONDAY. ACROSS THE CENTRAL GREAT LAKES, WIND-SWEPT RAIN AND
EMBEDDED THUNDERSTORMS LATER TODAY INTO TONIGHT ARE FORECAST TO
TURN INTO A BLIZZARD BY EARLY ON MONDAY WITH BLOWING SNOW.
SNOWFALL AMOUNTS ARE EXPECTED TO WELL EXCEED A FOOT ACROSS THE
UPPER GREAT LAKES, PARTICULARLY ALONG THE SOUTH SHORE OF LAKE
SUPERIOR WHERE 2 FEET OF SNOW IS POSSIBLE TOGETHER WITH WHITEOUT
CONDITIONS AT THE HEIGHT OF THE STORM. SEE THE LATEST WPC KEY
MESSAGE AT WPC.NCEP.NOAA.GOV FOR FURTHER INFORMATION ON THIS
POTENT WINTER STORM.
WINTER PRECIPITATION ASIDE, THE ARCTIC COLD FRONT SWEEPING SOUTH
WILL BRING A DRASTIC END TO THE WARMTH TODAY AS A QUICK ROUND OF
STRONG THUNDERSTORMS SIGNAL THE ARRIVAL OF THE "BLUE NORTHER".
AREAS FROM THE ARKLATEX TO THE MIDWEST CAN EXPECT THESE
THUNDERSTORMS TO SWEEP THROUGH LATER TODAY, FOLLOWED BY THE
OHIO/TENNESSEE VALLEYS AND THE DEEP SOUTH INTO MONDAY MORNING. A
COUPLE OF TORNADOES AND DAMAGING WIND GUSTS ARE POSSIBLE WITH SOME
OF THESE STORMS IN THE OHIO VALLEY THIS AFTERNOON OWING TO THE
UNUSUALLY WARM AND MOIST PRE-FRONTAL AIRMASS IN PLACE. BY
TOMORROW, THE ARRIVAL OF THE ARCTIC AIRMASS ACROSS THE EAST COAST
WILL USHER IN SHOWERS AND GUSTY WINDS FROM THE WEST, LEAVING IN
IT'S WAKE HIGH TEMPERATURES 30 TO 40 DEGREES COLDER THAN TODAY
ACROSS MUCH OF THE NATION'S MIDSECTION.
IN THE WEST, TRANQUIL CONDITIONS WILL BROADLY PREVAIL AS THE
DEVELOPING BIG STORM IN THE UPPER MIDWEST BECOMES THE DOMINANT
FEATURE ACROSS THE LOWER 48, WITH THE EXCEPTION BEING SOUTHEASTERN
NEW MEXICO AND SOUTHWEST TEXAS TOMORROW AS BLOWING, ACCUMULATING
SNOW FALLS NEAR THE TAIL END OF THE ARCTIC FRONT. MEANWHILE, THE
BIG STORM IN THE GREAT LAKES WILL SLOWLY MOVE INTO EASTERN CANADA
LATER ON MONDAY. BUT THE HUGE CIRCULATION OF THE SYSTEM WILL
CONTINUE TO SPREAD VERY STRONG AND GUSTY WINDS INTO THE ENTIRE
EASTERN U.S. WITH SNOW LINGERING ESPECIALLY DOWNWIND FROM THE
LOWER GREAT LAKES. RAIN SHOWERS SHOULD TAPER OFF OR END AS LIGHT
SNOW ACROSS MAINE BY TUESDAY MORNING BEHIND THE COLD FRONT.
ASHERMAN/KONG
AREAS OF SNOW CONTINUE TO EXPAND ACROSS THE NORTHERN PLAINS THIS
AFTERNOON, WHILE RAIN AND EMBEDDED THUNDERSTORMS ARE TRACKING
MIDWEST AHEAD OF THE LOW PRESSURE CENTER.
