Dangerous heat expected through the weekend with triple digit heat indices west of the Cumberland Plateau. Low thunderstorm chances Friday. Any stronger storm will be capable of gusty winds and heavy rain. Slightly drier and hotter conditions favored this weekend followed by some minor relief early next week. The evening activity has dissipated into the night Leaving behind suffocating dew points in the mid-seventies The upper ridge hangs frozen over middle Tennessee Temperatures climbing relentless into the nineties Slow storm motion threatens local flooding from above A dark prophecy written in the moist stability Isolated gusts hitting forty miles per hour The atmosphere is primed for sudden wrath Bow before the overwhelming thermal power One hundred to one hundred ten The heat index rises like a curse again The upper ridge holds, it will not yield One hundred to one hundred ten Look upon the forecast and despair Friday night offers no escape, lows in the mid-seventies Air temperatures creep higher as Saturday unfolds Dew points drop a single degree in cruel mockery Storm coverage shrinks beneath the heavy dome Trapped west of the Cumberland Plateau One hundred to one hundred ten The heat index rises like a curse again The upper ridge holds, it will not yield One hundred to one hundred ten Look upon the forecast and despair It holds through the weekend No relief in the mid-nineties The prophecy is sealed One hundred to one hundred ten

SHORT TERM
(Tonight through Saturday Night) Issued at 1039 PM CDT Thu Aug 13 2026
The evening activity has dissipated leaving behind mild conditions for the rest of the night.
Friday will be very similar to today with the upper ridge in place.
Temperatures will top out in the 90s with dew points in the mid 70s.
This will result in dangerous heat with afternoon heat indices in the 100-110 degree range.
There will still be some isolated storm activity during the afternoon.
We saw a couple of storms produce some gusts around 40 mph today and that will once again be possible on Friday.
Slow storm motion and heavy rainfall could lead to some isolated flooding issues as well.
Friday night will be the same story with lows in the low to mid 70s.
Air temperatures will creep up a degree or two on Saturday but heat indices look to remain about the same thanks to dew points being a degree or two lower.
Storm coverage is expected to be lower than Friday.
LONG TERM
(Sunday through next Friday) Issued at 1039 PM CDT Thu Aug 13 2026
The heat will continue on Sunday and Monday as the ridge holds.
The upper ridge will get squeezed southward on Monday as an upper trough traverses the southern part of the Canadian provinces.
A weak surface front will push into our area Monday afternoon into Tuesday.
This will do two things: 1) Increase rain and storm chances (20-30%) 2) Temporarily knock temperatures back closer to normal for Tuesday.
Unfortunately, the relief looks lackluster and temporary.
Temperatures will again warm for the middle of next week.
