Realy track one major system to affect the country the next few days producing just about everything including heavy rain, heavy snow, maybe some ice, and even a few isolated severe storms.
The setup will see an upper trough dig from the Northern Plains to the Southeast, and a surface low that will track down the Plains today through the South Saturday, and then up through the Mid-Atlantic Sunday and into southern New England by Monday morning. Several inches of snow will be possible mainly on the northern side of this system from southeast SD to northern MO today/tonight, southern MO to western TN Saturday/Saturday night, and then from central TN to western NY Sunday/Sunday night. Rainfall in excess of 1.5 inches or more will be possible for much of AL, GA, the Carolinas. and the FL panhandle. As for an isolated severe storm threat, that will come possibly Saturday/Saturday night along the FL Gulf Coast from Pensacola to Tampa Bay.
