Because this is the eve of the Country Music Marathon, Franklin’s Main Street Festival, countless baseball, soccer, [insert preferred outdoor sport] games, let’s go way overboard with the weather models. We’ll ask the weather models about Tonight, Sat 7 a.m., Sat 1p.m., and Sat 7 p.m. Sunday’s forecast is mentioned at the end. read more

We are in the peak of tornado season in Middle Tennessee. The good news is there is no widespread severe weather in the forecast.

Tuesday

Clouds arrive. read more

Monday & Tuesday

The run of nice weather continues. Monday we’ll hit 73, Tuesday 74. Rain may sneak in late Tuesday night.

Wednesday

A cold front is forecast to shove rain and maybe a few storms during the wee hours of Wednesday morning. Severe weather is possible off to our west, but modest dew points and meager instability should limit our severe weather potential. Expect around 1/2″ rain, mostly Wednesday morning.

Thursday & Friday

Clouds and sun, highs 67 Thursday and 71 Friday.

Saturday – Country Music Marathon
