Ok Here We Go!!!!

Confidence is now high that much of the Deep South will be impacted by a major winter storm Sunday and Monday with great impacts to North and Central Alabama possible, and we will fine tune everything tomorrow. Right now At this point, it looks like heavy snow is a very real possibility over the northern third of Alabama. Areas in and around Decatur and the Tennessee River could see 4-8 inches of snow Sunday afternoon through Monday morning. The main period for this heavier snow will be from around noon Sunday through noon Monday. There is a chance that there could be a lot more than we are thinking right now. Euro model has 7-9 inches, The NAM model through midnight Sun has 4-6" for Huntsville, the DGEX model (Which is below) that starts where it leaves off adds 8-9" more for a total of 12-14, and the GFS has about 4-6" inches. So this goes to show you the model madness is still there but this time it is a madness on the depth of snowfall we will see. Whatever does fall will for sure be around for days, and the travel problems will be real bad as well. Now lets turn to the possibility of ICE. There is a potential for Ice from the I-20 corridor to the south including Tuscaloosa and Birmingham with snow accumulations of snow on top of the ice as well.


DGEX total snowfall estimates


HPC 5 day valid thru Next Tuesday. There is a potential for a lot of precipitation with this system. Remember the ratio for rain/ snow is 10" of snow= 1"of rain.

NAM 06z Monday (which is Midnight Sunday) snowfall potential. This model is just now getting in line with the others. So the eastimates may go up.

This is the Canadian valid 06z Monday. This model is a little more robust the last few runs. On this particular one it looks as if 8-10" of snow in Huntsville.

This is the European model that nailed the Christmas Snow across Alabama valid 06z Monday. It is a little weaker than the Canadian but it is still 4-6" possible.
