Quiet with persistent clouds Wednesday, but rain returns tomorrow!
Good afternoon Tennessee Valley,
It looks likely clouds will persist for much of the day. Perhaps some peeks of sun in the afternoon, otherwise, temperatures will be rather on the balmy side this afternoon with highs in the middle to upper 50s feeling more like late November.
Tonight, temperatures will be 10 degrees above normal in the low 40s. Thursday will bring more clouds and showers by afternoon, once again in the upper 50s. A strong system arrives on Thursday night bringing heavy rain and a few thunderstorms. At this time, severe weather does not look likely, however rain and storms will produce high rainfall rates Thursday night, leading to localized flash flooding and river flooding through Friday morning. The heaviest rain arrives west of I-75 by 8PM-9PM in the evening, increasing in Chattanooga by 10PM-Midnight. This is when the heaviest rainfall looks to occur, moving east of I-75 by Friday morning 1AM-3AM.
There will likely still be showers ongoing on Friday morning for the commute east of Chattanooga, with clouds breaking by Friday afternoon. Rainfall amounts of 1" to 3" is very possible with this event.
Besides the rainfall, a Wind Advisory will be valid starting at 6AM CST Thursday through Friday 6AM CST for Grundy and Van Buren counties, for sustained winds of 15-30 mph and gusts up to 45 mph. This will also be valid for Sequatchie, Bledsoe, and Marion counties starting at 7AM EST through Friday morning at 6AM EST for sustained winds of 10-20 mph and wind gusts up to 40 mph. This means, holiday decorations, trash cans will be displaced, and loosened soils/weak tree limbs could result in downed trees. Please plan for a wet commute on Friday morning, with downed debris in these locations.
