Good morning/afternoon Tennessee Valley,

There's a lot to get to over the next several days, so let's get to it.

Dew points have risen to the upper 60s this morning. This will rise to the 70s by afternoon making a high temperature of 90 feel more like 92-95 today. Showers will be developing east of I-75 by 2PM.  Isolated showers/ t-storms look to be tracking west/northwestward in the evening, ending by 7PM. There's a slightly better shower chance today, so keep the umbrella handy.

Isolated rain chances and temperatures near 90 will be trend through Saturday. New forecast model data places now the remnants of Hurricane Florence over the Tennessee Valley Sunday through Monday.

I've increased pops to 30% for rain Sunday and 40% for Monday. Areas that will have the biggest impact in the Channel 3 viewing area will be in the highest elevations as wind speeds of 30-40 mph will be increasing at 2500 feet above sea level. 

With that said, areas on Lookout Mountain may experience these wind gusts starting up on Sunday, and closer to the Blue Ridge stronger winds up to 50 mph look possible. This means, downed trees and power lines can't be ruled out Sunday through Monday. Rain will be increasing Sunday morning over the Blue Ridge by 6AM-9AM. Areas east of I-75 will have the best potential for rainfall during the day on Sunday increasing from I-75 and west Sunday night through Monday of next week. Rainfall doesn't look terribly impressive for Chattanooga near 0.30" to 1" Sunday-Monday, while those east of I-75 over Polk, Monroe, Cherokee, Gilmer, and Fannin counties 2" to 4" looks possible.
