The remnants of Tropical Storm Harvey is forecast to push northeast into Tennessee by Thursday night into Friday morning, bringing with it the chance for very heavy rain, some localized flash flooding, and a relatively small tornado threat.
Rain chances will begin as early as late afternoon today with the first bands from the storm pushing north into Middle Tennessee.
Rainfall amounts will range from 3-5 inches across most parts of the Nashville Metro.
And isolated small tornadoes are possible with this system as it pushes across middle Tennessee...
This is the Hazardous Weather Outlook from The National Weather Service:
500 AM CDT Wed Aug 30 2017
This Hazardous Weather Outlook is for portions of Middle Tennessee.
.DAY ONE...Today and Tonight
The remnants of Hurricane Harvey will begin to affect our weather significantly today and tonight. Rainfall amounts will start to increase overnight.
.DAYS TWO THROUGH SEVEN...Thursday through Tuesday
Heavy rain will persist through Friday as Tropical Depression Harvey moves across Middle Tennessee. Total rainfall amounts through Friday are expected to range from less than 2 inches across southern parts of the Cumberland Plateau, to more than 3 inches across the Nashville metro area, to between 6 and 8 inches around Clarksville and Land-between-the-Lakes. As rainfall amounts accumulate over a period of days, flooding may develop, particularly in areas to the west and north of Nashville.
In addition, all of Middle Tennessee is under a marginal risk of severe storms Thursday and Thursday night. As the center of low pressure moves directly across the mid state, it is possible that isolated tornadoes may occur, especially Thursday afternoon.
.SPOTTER INFORMATION STATEMENT...
Spotter activation may be needed tomorrow for severe storms, and also later in the week should flooding develop.
