Thursday Night/Friday Southeast Winter Event Update.

Previously I mentioned that things are just not adding up to make this a memorable snow event.  As the time has gotten closer to the actual event this is proving to be more true.  Here is the synopsis on it and the reasons why this is proving to be more of a rain event for most of The South.  Temperatures right now for The Southeast Region are ranging from the mid-30's in the northern portions of AL, MS, and GA to the mid-50's in the southern potions of the states.  A cold front is already in central MS and northern AL and continuing to push towards the east-southeast.  Precipitation is stretching from southeast LA thru southern and eastern MS thru central and northern AL and further north in central and eastern TN.  The snow is being experienced in northern AL and most of TN.  The rest of it is all rain.  What this is saying is that where the snow is being experienced is where the cold front has already passed through and sending in the cold air to allow the snow to fall.

Now to tell the reason why the wintry precip isn't going to be as far south as once forecasted.  There is a lot of cold air that is behind the cold front and will drop temperatures low enough for snow to fall, but most of the precip. is ahead of the cold front and gradually dissipating behind the cold front.  This means that most places in The Southeast, with the exceptiong of TN and northern AL, will just see rain and thats it.  Northern AL could see up to a half inch of snow and that is about it.  TN, however, could see as much as 3 inches in some places like along the Cumberland Plateau.  Some people might worry about ice accumulation like the last winter event we had in The Southeast Region.  Ice will not be a worry what so ever either because temperatures have been warm enough to keep the ground from freezing even with the falling temps. from the cold front.

Overall, have no worries for all the people in The South.  Rain will be all of your worries for tonight and into Friday.  Tennessee will see multiple school and business closures due the amount of snow likely to fall.  There will, however, be another winter event pushing into The South Sunday into Monday.  That is far enough in the future where there are a lot of uncertainties to it such as how far south the low pressure will push, where the freezing temperature line will be, and how much precip. of both frozen and liquid types will fall.  I will update more information about this next winter event as it gets closer.
