It is not too common to see a perfect lake forecast in October, but we have one this weekend. Typically, we have high's in the upper 70's to lower 80's this time of the year, but we will be dealing with lower 90's the next several days. Looking below at the expected temperatures across the US on Tuesday, very warm across the eastern half of the United States. This is all associated with a strong ridge, locking in warm temperatures, keeping us dry, and making things feel muggy outside. Oppositely to the west, very cold temperatures (associated with a deep trough) and that will provide the first major snow of the year for parts of Montana and the Rockies. This will likely be a very strong blizzard with feet of snow expected to fall in the Rockies early next week. This eventually will slide toward the east, which in turn, will bring some cooler temperatures and the chance for some much needed rainfall to east TN. We will be eyeing this as it grows closer to time late next week.
For our surface map, you can see the high pressure system keeping things dry across the region through the weekend. We could see an isolated shower (mainly in the higher elevations) tomorrow afternoon associated with the low to our north, but that will quickly move out leaving us sunny through next week.
With the lack of rain last week and into much of this one, the drought monitor for the state has increased dramatically to a moderate drought. Toward the south for our friends in Bradley and Hamilton counties (Chattanooga), very dry with a severe drought intensity. Unfortunately, this will only get worse as we will remain hot, sunny, and dry over the next week or so.
The latest model guidance shows the chance for an isolated shower in the higher elevations tomorrow afternoon. For us in the valley, though, expect to stay mostly sunny and dry with high's in the lower 90's.
Thats all we have for your Friday, but go out and enjoy an early October lake day with mostly sunny skies and highs in the 90's. Have a great weekend!
