Each Has An Entirely Different Personality
A storm system moving across the Lone Star state Friday will be strengthening in the Gulf of Mexico, developing a strong low pressure area which will be the center of large scale storm circulation. While the upper level winds will be controlling the track of that storm, a secondary area of lowering pressure will then move into the Mid-South, and could… COULD… throw this forecast into a bit of a spin. SO it is indeed becoming a MUCH more interesting forecast.
Unless a secondary low pressure area moves the first system off track, the core of heaviest snow will fall from between Montgomery and Birmingham to Columbus and Atlanta, then into the Carolinas. The northwestern extent of the accumulating snow will likely remain south of a Hamilton to Cullman to Fort Payne to Chattanooga line. If the secondary storm forms, that line could back into Decatur, Huntsville and Fayetteville. If the forecast is wrong, that is the direction of error.
Later in the weekend, another storm will drop toward the Tennessee Valley from the northwest, potentially starting off as a rain/freezing rain/sleet/snow mix, stopping, then restarting later as the same mix before converting to all light snow Sunday night and Monday. It is too far away to discuss any accumulation chances, at this point, any would be light.
COLD temps will remain for the next week.
