Today's video starts with a look at a storm off the North Carolina coast, then winds through the twists and turns of the next week's changeable weather patterns.
THE CHAMELEON MONTH OF MARCH
This is the chameleon month of March. Always searching for a sense of identity, its days stagger through punches of waning winter, dance with the sunlit caresses of coming spring and hide behind thick clouds through the wind-swept battles between the two.
The midday sky looks brighter now, but the sun sneaks out of view before the dinner dishes can be cleared. Winter's cloak of white melts down to oozing mud and rushing streams. The crocus and daffodil bravely blossom, but wiser plants bide their time til a less treasonous season. Dark December, Jailer January and Fortress February no longer hold the keys around here. We peer out and the door to winter's dungeon creaks open.
And yet, rather than seizing this moment of weakness, rather than racing headlong into warmer times, spring prefers the test-market approach: try a hint of south wind here, a puffy cumulus there; teasing breezings between the freezings. Even the south wind has ragged, chilly edges on many a March day; subtle hints of warmth vanish all too quickly in the gathering dim of dusk.
Like a 12 year-old on Saturday morning, March is full of hope. However, Mother Nature and Old Man Winter rule the household. One day, with icewater in its veins, the northwest wind can blast in from the still frozen hinterlands of the Arctic north.
However, if the south wind quickens, there's usually some double-agent storm waiting in the wings, a two-faced wanderer of the westerlies dealing dreadful thunderstorms on its south side and freezing gales with drifting snow to its north. As storms approach, the day carries a hint of mildness, but the fading sun gives ground to a milky veil that would all too readily drop snow but for the want of a few degrees.
Through it all we mortals whose days are most surely numbered somehow yearn for them to pass ... so sweet the lure of prospective spring: its meadows splashed with gold, its captivating sunshine, its renewal of earthly life. The set changes each March, and the players follow different scripts, but it's really the same show. No matter how many times we see it in life, we're always ready for it again. For as much as March means memories of dark, chilly winter, it surely means brighter and better times are just ahead.
On this map from 10 a.m. ET Thanksgiving Day, you can see the high pressure area that is causing dry and mild weather in the East and the cold front farther west.
During the late afternoon and early evening hours, the cold front of a knife will slice through the turkey and cause it to accumulate 1-2 inches on plates...
This satellite picture shows clouds over parts New York and Pennsylvania, as well as areas of low clouds, fog and snow cover from Michigan to Illinois. Most of the Northeast should have at least some sunshine through Thanksgiving Day.
As we go through the week, the flow aloft over the East will become southwesterly. This will promote a major warmup. This map shows the projected upper-air flow for Thanksgiving afternoon:
A major snowstorm will affect the area from Iowa to Michigan tonight and tomorrow. At first, snow can melt on streets, but as it continues and the temperature drops, the area impacted by slippery conditions will increase dramatically. This map shows expected accumulations:
This map shows two cold fronts in the northeast quarter of the nation; 9 a.m. ET temperature are plotted. The isobars are closest together over the central and western Great Lakes, and this is where the strongest winds were occurring.
