Thursday 9 A.M.
The powerful storm that caused tornadoes across the Gulf states, heavy snow from Texas and Arkansas to northern Maine and wind-driven, heavy rain along the East Coast from Maryland to southern Maine was centered just south of Cape Cod at 9 a.m. this morning.
A new storm will from in the Gulf states tomorrow and track toward New England's offshore waters by Sunday morning. By taking that kind of track, the chance of accumulating snow is increased for the I-95 corridor. Last night's various computer projections showed scenarios ranging all the way from no snow to heavy snow. This video is illustrated using one GFS version from its 1 a.m. EST run this (Thursday) morning.
Outside our house (in central Pennsylvania), the falling snow was highlighted by the camera's flash around dusk last evening. It looked like an outdoor version of a snow globe.
A storm that has brought hardship and danger to parts of Texas and Arkansas with an assortment of ice and snow will send a swath of snow northeastward today and tonight. Here is a map showing our overall estimates as of 10 a.m. ET:
That could lead to tough travel at the end of the weekend. This map for Sunday at 7 p.m. ET shows where those troubles could be (north of the line with the label "snow rain line.")
This table shows the ensemble means for the next two weeks at Philadelphia: It suggests that whereas it does turn cold, any snowfall looks quite limited.
It is too early to be confident about any forecast for Christmas Day (or even the week before). However, the GFS model does go out 16 days, and it has a cold look for the Northeast exactly one week before Christmas.
As the flow aloft becomes southwesterly, mild moist air will spread northeastward from the Gulf States. In summer, this creates a hazy, very warm and humid scene for the Northeast. Now though, the warmth is slowly drained away as the moist mild air advances over cold ground. With temperatures near the saturation point, clouds form.
If each one of us lights an inner flame for just one thing- just one aspect of our lives we are thankful for, the warmth we create can light the world on Thanksgiving. The flame of warmth and love can burn so bright that no cold wind on earth can blow it out.
