Snow Possible Tommorow and Tomm. Night

I can't resist there is snow forecasted for tomorrow and tomm. night.


First before I say what I am going to say know that the models that show this nice snow system have been poor at best, and that we have saw total model agreement go up in flames on the day of the event this past 2 winters so this event and any more that may occur in March will have a low confidence.


We will start as a trough digs into the southeast a low pressure system will form in South Alabama into South GA. This will cold air nearby will be moisture into TN and even into parts of West and Central KY not a lot of moisture but that is that main uncertainty. It may be enough to where bands of snow may form after the rain that will start tonight and tomorrow by model guidance the rain will change to snow by noon west of I-65 and by say 6pm east of I-65 if it doesn't change by those times or soon after than we will probably have to chalk up another bust event.


Tough part is not only when rain changes to snow but where a band of heavier snow may set up. This might be one of those events where a dusting might occur at your house but 10 miles down the road they have 5 inches of snow.


While nothing like March 2008 or March 1996 is expected it is late Feb/March where surprises can occur.


Right now for west ky esp south of the West KY Parkway 1 to 1 and a 1/2 inches of snow seems reasonable if things go as planned. If banding occurs could be locally more.


For Mid TN about 1 to 2 inches could occur but depending on some models and band may run across North TN from Springfield to Jamestown TN area down to the plateau and produce up to 4 inches of snow but that is very low confidence of now.


stay tuned for updates on this potential winter situation and enjoy as it could be the last winter storm chance of this winter.
maybe it will maybe it won't
