A 4WARN Weather Alert is in effect through the weekend for the threat of flooding as 3-6″ of rain is possible between now and Sunday. The National Weather Service has posted a Flood Watch in effect for half of the mid state through Saturday night.

Widespread rain will fall into the evening, getting heavier overnight with possible isolated thunderstorms. Those should not be severe. Temperatures are cooler this evening than this morning as the front has now passed the area. Showers and some thunderstorms will continue in waves overnight and on Thursday. Here is the latest Futurecast depiction.

Friday the rain will not be as widespread, but you’ll still want to keep the umbrella with you. Temperatures should rebound to the 70s. Here is the latest timing with the Futurecast model.

Late Saturday, strong thunderstorms will pass through. Some of those storms could be severe with damaging wind. After some morning showers the weather will dry out and cool down some on Sunday, but still we’ll have a high in the low 60s. When all is said and done the northwest corner of Middle Tennessee will have received the most rain. That is where flash flooding is most likely.

Monday and Tuesday will be sunny and mild. Yippee…that’s good news after days of rain. I’ll have the latest on the forecast after the Olympics on News 4.
