A cold low is churning well to our north with an upper level disturbance passing through the area. This will provide renewed showers today, with increasing chances this afternoon and evening. A changeover to rain/snow mix can't be ruled out overnight either. Temperatures today will be chilly, ranging from the upper 40s to mid 50s. Cooler temps continue into Saturday as well, with highs in the upper 40s and low 50s.
Looking at guidance, scattered showers will become more widespread this afternoon with a few thunderstorms possible. Transitioning overnight, temperatures will cool and and a change over to rain/snow mix will be possible. No impacts are expected across the majority of East Tennessee, but the same can't be said for the higher elevations. Locations 2500 feet and above will see the opportunity for accumulating snow overnight and into Saturday. Those that hike, camp, or may be in the Smokies, plan ahead and don't be surprised to see some snowfall.
Other than showers today and into early Saturday, our next round doesn't arrive until mid week. Early analysis suggests heavy rainfall will be possible, but where this band sets up will be in question. For now, the WPC suggests this to be a bit further southwest, but changes are likely and a slight trend more eastward has been seen. We'll keep a close eye on this but for now, brace for a cold rain and below average temperatures through tomorrow.
Forewarning, cover those plants tonight and tomorrow! Low temperatures in the upper 20s to low 30s could easily kill newly planted seeds and plants. A frost/freeze advisory or warning will likely be issued for tonight and/or tomorrow night. By Sunday, things will warm back up with sunshine again in the forecast.
