Showers & Storms Tonight Into Saturday

A slow moving cold front brings the threat of heavy rains tonight, where a marginal threat of flash flooding is in place according to WPC. I believe this is an excessive excessive rainfall outlook given how dry we have been the past 10 days, but it is there nonetheless. As such, keep in mind heavy swaths of showers and/or storms will be possible later tonight into Saturday. Activity will then begin to diminish from west to east into Saturday afternoon, where sunnier skies find East Tennessee Sunday. 

Along with sunshine, MUCH cooler air will also come. This graphic below represents our usual average compared to expectations for the day. As you can see, highs will be 10+ degrees below average, generally in the upper 50s to low 60s for the day. That is a 20+ degree swing from what we will see this afternoon. We will warm a touch toward mid week, but really below average temperatures should be expected from Sunday through Friday.

Another shot at rainfall will also be in the forecast, where additional amounts up to an inch will be possible. This next week system will primarily impact the Tennessee Valley and south towards mid week. This will add to our rainfall tonight into Saturday, bringing total rainfall amounts of 1-2" over the next 7 days. Locally higher amounts will be possible within thunderstorms.

That will do it for today. After the warm and dry weather we have had changes are in store. Unsettled and cool conditions return through much of the next 7 days.
