Unseasonably warm this week. A roller coaster ride of temps will follow.
False fall is over, and highs are back in the 90s for the next few days. Rain chances are few and far between, until we get to the end of the weekend. It's the Tennessee Valley's first shot at rain in about two weeks. No rain chance for the rest of today. Temperatures near 90 will cool off into the 70s this evening.
Temperatures will continue to climb through Thursday, until an approaching front will cool us off significantly. This will be a dry front- no rain chances to come along for the ride. We will still reap the benefits of cooler temperatures in the wake. highs will go from 90 to upper 70s within a day.
Before we get to the end of the week cool down, we will be dealing with very hot temperatures and heat indices near triple digits. With the frontal passage during the day Thursday, temperatures will still reach the upper 80s at least- but will quickly come crashing down. Lows Wednesday night will be in the upper 60s. Lows Thursday night will be in the mid 50s.
Our next rain chance comes with another approaching front that will affect us as early as Saturday night. Right now, it's looking like Sunday will hold the highest rain chance, but rain is also possible late Saturday night and early Monday morning.
An update on Hurricane Fiona this afternoon shows the storm strengthening as it moves north of the Dominican Republic. Fiona is a Category 1 storm as I write this, but is expected to strengthen into a major hurricane (Category 3 or higher) by Wednesday morning. While Puerto Rico and the Dominican Republic are dealing with the aftermath of the storm, the storm will miss the lower 48 and turn northeast out to sea.
The National Hurricane Center is also monitoring another potential tropical development that could form early next week. While it's still too early to tell much about what could develop and where it could be headed, models are hinting at the Gulf of Mexico. We will keep an eye on this potential development and what it could mean, if anything, for the gulf coast.
