Snowstorm Threat Shifts South, Hold Everything!

Hold everything! The latest indications are the cross-country storm will shift farther south, raising concerns for substantial snow in places that rarely get it.

Based on the behavior of the storm Tuesday and Wednesday around California, AccuWeather.com meteorologists now believe the cross-country storm will track farther south into the eastern third of the nation, and do so at a slower pace.

Interestingly, a more southern track and push of cold air raises the "possibility" of some snow for Southern cities such as Birmingham, Atlanta and Charlotte.

The new, slower storm idea, now being adopted by AccuWeather.com, would still have disruptive snow pushing across the northern Plains and mid-Mississippi Valley into Christmas Eve, then during the nighttime hours farther east over part of the Ohio and Tennessee valleys.

The possibility of snow in part of the South comes more on Christmas Day.

According to meteorologist and Southern weather veteran Mark Mancuso, "A number of features have to come together for accumulating snow in the South."

Mancuso stated, "Path of the storm with warm versus cold is one big issue, and the speed of dry air racing in, potentially causing the snow to evaporate before reaching the ground, is another."

"This is likely to be a two-loafer," Mancuso added.

Mark was referring to the typical rush on bread (and milk) at grocery stores that occurs when a snowstorm threatens the South. "One loaf for the storm, add a second since it is threatening on Christmas," He said.

Even a couple of inches of snow are a big deal in the South. It is huge, since it will be occurring on or around Christmas.

The issues of a more southern storm, and perhaps a more intense track, have big implications along the Atlantic Seaboard.

Hold on for the ride!

As far as AccuWeather.com meteorologists' take on the expensive, high-tech computer models with this storm, "None of them are right."

People need to pay close attention to the UV index during this time of year. On a sunny day late in the spring and into the summer, the UV is usually at least an 8, which is very high. Readings over 11 are considered extreme values in which only 10 minutes of full exposure to the sun will produce a sunburn.
