The high pressure that has been pumping in moisture from the Gulf will begin to usher in even more moisture during the day Friday. This will make our chances to see showers and thunderstorms “likely”.
The NAM has the rain beginning to fall as early as 10 AM.
The NWS thinks that two inches of rain fall is possible for many areas but widespread flooding will not be an issue.
A disturbance will approach from our West keeping our rain chances at “likely” overnight.
Saturday– Mostly Cloudy, Chance of Thunderstorms – Wake Up 71, High 88
The disturbance will attempt to cross through Middle Tennessee on Saturday, but an upper level high will cause it to wash out (disintegrate). Ample low level moisture will fuel showers as the the disturbance attempts to track across Middle Tennessee.

These showers and thunderstorms will continue overnight into Sunday.
