Rain and storms for Thursday. Clearing for Friday and Saturday. Unsettled heading into next week.
We've had a few "illegal" showers across the Tennessee Valley from time to time today, especially across southern middle Tennessee. These have become much more isolated as we have worked into the afternoon, but one or two will still hang around into the early evening hours before dissipating with the loss of daytime heating across the area. Otherwise, it's been a cloudy, breezy, warm day for everyone with highs in the upper 70s and lower 80s again areawide.
Looking at temperatures nationally, warmer air is in place across much of the central and eastern portions of the United States, and even as a frontal boundary works through the area, that warmer air isn't really going anywhere. We only step down into the mid 70s behind the front for Friday and Saturday before rebounding into the upper 70s and lower 80s again coming out of the weekend and going into early next week.
That aforementioned frontal boundary approaches on Thursday, bringing a good chance of showers and thunderstorms to the area. A few widely scattered showers may be around as early as the morning hours, but the more widespread activity moves through during the afternoon and overnight, before tapering off during the predawn hours of Friday morning. One or two of the storms may be strong during the afternoon and evening, with gusty winds or maybe even small hail, but the overall risk of organized severe weather is very low, and the risk of a tornado is as close to zero as is possible.
Clouds clear out during the day on Friday, and we are left with a nice first half of the weekend, with a mix of sun and clouds and highs in the mid 70s going through Saturday. However, unsettled weather returns to the area Sunday through midweek with multiple chances of showers and thunderstorms each day.
