.UPDATE...
Issued at 635 PM CDT Sun Jun 28 2026

As an upper ridge builds over the midwest and Ohio River valley,
temperatures will warm into the mid-upper 90s for most of the mid-
state. With surface dewpoints in the 70s, the heat and humidty
will yield heat index values of 105 to 110 degrees for areas
within the Extreme Heat Warning. On portions of the plateau where
it`s cooler, heat indices will still approach the high 90s. Expect
little relief at night as lows in the 70s, especially mid to high
70s for the western two thirds of Middle Tennessee, will persist.
Winds will be light enough for some patchy fog development later
tonight and again tomorrow night, but coverage is going to be
localized and a Dense Fog Advisory is not anticipated at this
time.

.SHORT TERM...
(Rest of today through Monday)
Issued at 1220 PM CDT Sun Jun 28 2026

Our focus is now going to turn to dangerous heat over the next
week. A short wave trough is exiting the eastern part of the
state and as it does we will see dry conditions set in. There will
be just a low chance for a few pop up showers and thunderstorms
through 6 PM. Highs this afternoon will reach the lower 90s with
afternoon heat index values as hot as 106.

An upper level ridge has already started to amplify over the
central part of the country and will continue to build over the
next week. This will bring dangerous heat to the area starting
Monday and will last at least through Friday. Monday highs will
warm into the mid to upper 90s. Dew points will be humid in the
low to mid 70s pushing afternoon heat index values as hot as 110.

.LONG TERM...
(Monday Night through next Sunday)
Issued at 1220 PM CDT Sun Jun 28 2026

The upper level ridge will continue to amplify and be centered
over Middle TN through at least the middle part of the week. This
will bring a prolonged period of very hot temperatures. Highs
through at least Friday will be in the mid to upper 90s and
afternoon heat index values will be as hot as 110. There will be
limited relief from the heat overnight as lows will only fall into
the mid to upper 70s. This heat and duration will bring extreme
heat risk to much of Middle TN by Tuesday and will remain extreme at
least through Friday. Extreme Heat Risk means that there is rare
and or long duration extreme heat with little to no overnight
relief affecting anyone without cooling/hydration as well as
health systems, industries, and infrastructure.

The upper level ridge will drift east late week and start to
break down some next weekend. That will bring some cooling for the
4th of July weekend but it will be limited. Highs will still
remain in the low to mid 90s with afternoon heat index values in
the triple digits. With the upper level ridge just to our east we
will see low chances for pop up afternoon/evening thunderstorms
Friday into the weekend.
