Cold air is settling into the Tennessee valley tonight.  A shot of moisture continues to move from the northwest to southeast.  As the moisture moves in tonight the rain showers will become mixed with some sleet and then snow.  I think amounts will be light especially in the valleys.  Lows tonight will be in the low to mid 30's in the valley and near 30 in the higher elevations.  So as of now I think the road conditions should be pretty good in the morning.  As for amounts I think an inch is likely in the valleys, especially in TN and maybe an inch or two in some of the higher elevations.  The temperatures will be cold enough for snow but I think there will be a lack of enough moisture to make a big snow storm.

Highs will be in the low 50's Sunday as the skies clear.  Expect fair skies Sunday night with lows near freezing.  Rain will be likely Monday and flurries are possible Tuesday.  Highs both days will be in the 40's.

Wednesday will be chilly with low to mid 40's expected and partly cloudy skies.  Thursday should be sunny with highs in the low 50's.  A few showers will be possible Friday and Saturday with highs in the mid to upper 50's.
