Very heavy rain, the potential for flooding, and a few strong storms are possible late Wednesday night and Thursday.

Wednesday as a whole will be a lot like today.  It'll be warm, even windier than today, and a bit cloudier.  Start temperatures will look like this.

FUTURECAST -- Thursday 7am

There are two primary concerns with this weather system for Thursday morning.  The first is rainfall.  Tremendously heavy downpours, some persistent, could trigger flooding, especially where a Flood Watch has been issued.

There could also be a few strong storms with damaging wind gusts or even a short-lived minimal strength isolated tornado.  The primary threat area for that is southeast of Nashville.
