Lows tonight will drop into the mid 70s. Scattered storms remain possible through next weekend. The storm threat will be for hail and damaging winds. Greatest chance for storms will be Sunday night into Monday. Storms will gradually diminish once we reach sunset Sunday evening.
We finally start to dry out and heat up by the end of next week. The heat begins to build on Monday with isolated storms expected during the overnight hours Monday into Tuesday morning.
"Saturday's chance of rain is highest near U.S. 278 and lowest in Southern Tennessee; these storms may be heavy enough to deliver 1-2" of rainfall in a few spots, but that kind of rain looks sparse. High temperatures each afternoon will generally be in the upper 80s to lower 90s, just depending on where and when it rains each day.
Scattered and isolated showers and thunderstorms will form over the foothills Friday and spread to the northern plains by early afternoon. Winds will be very light with high pressure across the area.
That said I am still going with about a 40% chance for pop-up showers and storms Sunday afternoon, especially for the areas that saw the heaviest rainfall on Saturday.
Highs will remain in the low 80s through early next week before climbing toward more seasonal norms by Wednesday and Thursday.
