...COLD WEATHER ARRIVES OVER THE EASTERN U.S. TODAY; WINTRY
WEATHER TO SPREAD FROM THE MIDWEST INTO THE NORTHEAST...
..SYSTEM LATE THURSDAY TO PRODUCE SNOW ALONG THE NORTHERN TIER
AFTER AN UNSEASONABLY WARM AND DRY START TO THE WORK WEEK, COLD
WEATHER FINALLY RETURNS EAST OF THE MISSISSIPPI RIVER TODAY AS A
SERIES OF COLD FRONTS MERGE OVER THE OHIO VALLEY THIS AFTERNOON.
WHILE THIS COLD FRONT IS NOT EXPECTED TO SET ANY RECORDS, TOMORROW
WILL FEEL MUCH CHILLIER ACROSS MUCH OF THE EASTERN U.S AS DAYTIME
HIGH TEMPERATURES PLUMMET 10-20 DEGREES ACROSS THE BOARD BENEATH
ARCTIC HIGH PRESSURE. TEMPERATURES ASIDE, STRONG NORTHWESTERLY
FLOW BEHIND FRONT WILL FOCUS HEAVY LAKE EFFECT SNOWS IN THE
NORTHERLY SNOW BELTS OF THE GREAT LAKES. THE MOST INTENSE LAKE
EFFECT IS EXPECTED ALONG THE SOUTHEAST SHORE OF LAKE MICHIGAN,
WHERE 8-12 INCHES OF SNOWFALL IS POSSIBLE THROUGH THURSDAY WITHIN
A BAND WHICH IS FORECAST TO MATERIALIZE LATER THIS MORNING.
MEANWHILE, WINTRY WEATHER WILL BLOSSOM OVER THE OHIO VALLEY AND
NORTHEAST THIS AS RAIN SWITCHES OVER TO SNOW ON THE NORTHWEST
FLANK OF A DEVELOPING LOW PRESSURE CENTER. MODERATE TO LOCALLY
HEAVY SNOWFALL SHOULD PERSIST THROUGH TOMORROW AS THE LOW TAKES
SHAPE, LEADING TO SNOWFALL AMOUNTS OF 3-6" (LOCALLY HIGHER 8-10")
OVER PARTS OF THE APPALACHIANS AND THE TUG HILL OF NEW YORK.
BEYOND THURSDAY, ANOTHER SYSTEM IS FORECAST TO DIVE OUT OF THE
CANADIAN PRAIRIES INTO THE NORTHERN TIER, LEADING TO ADDITIONAL
SNOWFALL OVER PARTS OF THE NORTHERN PLAINS AND MIDWEST. WHILE
EXACT SNOWFALL AMOUNTS WITH THIS NEXT ROUND APPEAR PRETTY LOW AS
OF NOW, BLOWING SNOW MAY BE AN ISSUE WITH THIS SYSTEM OWING TO THE
STRONG PRESSURE GRADIENT IN PLACE. CHECK BACK FOR UPDATES AS
FORECAST DETAILS COME INTO VIEW.
