More Snow Possible Across the Southeast

Between now and early next week, it could snow 3 more times across places like Dallas, Atlanta and Charlotte, and most points in between. All of these "storms" are still iffy, but lets take the first one. A weak wave of low pressure begins to develop along a cold front early Wednesday across Mississippi and at the same time cold air aloft is coming into our area, light moisture should begin to overrun this frontal boundary. Right now it appears Shelby is on the western edge, but all the weather models do develop light precip, probably wet snow, around rush hour Wednesday and then taper it off by afternoon. I don't think accumulations will be a problem except on grassy areas and cartops, but it will be something to keep an eye on future model output to see just how close this becomes to something significant. The big deal could be the wind and the return to much colder air ushering in.

Up next, by early Friday another strong disturbance will be developing over the lower Plains around Oklahoma and Texas. Once again, snow flies there and streaks eastward into Arkansas and Mississippi. However by then, we have a strong cyclone sitting over New York City that is forecast to become extremely powerful and may actually supress the southern plains storm to our south. Yet, some models are actually close to bringing this system just to our south, and often times the models are a little too supressed with systems in this time range. So, something else to watch, but this one could barely miss us. Still, its worth mentioning for the fact that Dallas to Atlanta stand a reasonable shot at more snow in this unbelievable Winter.

The potential "big dog" is the final one. For several days now the models have all been adamant about developing a powerful looking low in Texas or the Gulf of Mexico by Sunday evening. This is getting really far out there, but it appears that cold air is still pouring into our region by then, and anything could happen with that storm. From total supression, to a full phase with northern energy and rain. Right now, its definitely worth watching as the most reliable models in this time range still paint a major snowfall across much of the Southeast, from about Atlanta to the Carolinas. If everything were to come together perfectly, this storm has the potential to drop around a foot of snow over a large area. But for now, thats all it is: potential.  Suffice it to say, Spring weather is going to be delayed yet again.  Already, this has been the coldest Winter since 1977/78....and thats something.

I'll have more updates as time goes along.
