A high pressure system sitting in the Gulf of Mexico is continuing to pump moisture into Middle Tennessee ahead of a disturbance that is forecast to move through this afternoon. The National Weather Service believes that our best chance to see showers and thunderstorms will be after 1 PM.

The HRRR shows an organized system of showers and thunderstorms breaking apart as soon as it reaches Middle Tennessee. The scattered showers are forecast to be in Williamson and Davidson counties in the afternoon hours.

Overnight, we will hold onto our chance for showers and storms as the disturbance continues to push through.

The SPC does not think there will be any severe weather in Nashville.

Friday – Mostly Cloudy,  Thunderstorms Likely– Wake Up 71, High 86

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.

The NAM has showers beginning as early as 7 AM and hanging with us all day.
