More of this? It could happen this weekend.

Like the football team leading by 60 points in the 4th quarter playing their third-stringers against a team that still can't stop them.
Well...writing this makes us feel like we're doing the same to the Midwest, South, and East.
First, we have the current heavy snow affecting the Appalachians, northern New England, and Great Lake snowbelts. Then, we have the widespread cold in the East, including record cold expected in Florida and the Southeast.

Our Facebook fans
have made their feelings crystal clear:
"I thought I left this behind me in Upstate NY when I moved to Orlando in August!" - Claudia Shae Palacios
"20's & 30's [above zero]? That isn't bad.... I live in Montana, where it was in the -20's & -30's over Thanksgiving week, with wind chills well into the -40's! +30's sounds like shorts & t-shirt weather to me! lol" - Eric Drissell
Now...a weekend concern.
Low pressure is expected to wrap-up in the Midwest Saturday, then track to the east Sunday. The exact track of the low is the key, as that will determine both the location and magnitude of weekend impacts. Unfortunately, this far out, there are key differences in the guidance meteorologists examine.
The heaviest snow will fall to the north and west of the track of the surface low. If the low track is farther north, the heavy snow swath will extend from the Upper Midwest into the Great Lakes. If the low track is farther south, it's the Missouri and Ohio Valleys, extending into Upstate New York that may see the most snow to shovel.
For now, here's a general outlook by region:
Midwest: Wind-driven, heavy snow in Plains, moving into the Mississippi Valley, Great Lakes, and possibly the Ohio Valley Saturday, continuing into Sunday, depending on the exact track of the surface low. Major travel disruption seems likely!
Northeast: Precipitation may start as either snow, sleet, or freezing rain Saturday night into Sunday mainly inland of I-95. A changeover to rain is expected particularly near the coast Sunday. However, locations from western NY through the Appalachians will quickly change back to heavy, wind-driven snow from Sunday through early next week. Major travel disruption possible!
Southeast: Severe weather threat looks limited, due to a lack of warm, moist air penetrating northward from the Gulf of Mexico. Some t-storms may bear watching near the Gulf Coast Saturday, then again late Saturday night into early Sunday from the Carolina coast into Florida. More snow is expected for the Smoky Mountains, and possibly parts of the Tennessee Valley late Saturday into Sunday.

And...you guessed it. Behind this weekend storm will be another blast of teeth-chattering cold air penetrating yet again into the Deep South and Florida.
So, again, we profusely apologize if we're "piling on". Look at the bright side...this may greatly increase the odds of a White Christmas!
