.SHORT TERM...
(Tonight through Tuesday Night)
Issued at 1033 PM CDT Sun Jun 22 2025

Strong high pressure remains over the eastern US and will still
be the main focus of this week as it`s responsible for dangerous
heat. High temperatures Monday & Tuesday will warm into the mid
and upper-90s each afternoon. And with dewpoints reaching into
the 70s each day, heat index values will continue to be in the
triple digits. A Heat Advisory remains in effect for most counties
west of the Plateau where heat index values are highest. Still,
it`ll be hot areawide so continue to practice heat safety,
including staying hydrated and taking breaks in the AC if you`re
outdoors for prolonged periods of time.

With high pressure controlling our pattern, this continues to
suppress widespread thunderstorm development. But with abundant
instability, this is still enough to allow for pop-up
thunderstorms each afternoon. Any stronger thunderstorm will be
capable of heavy rain and brief strong wind gusts.

.LONG TERM...
(Wednesday through next Monday)
Issued at 1033 PM CDT Sun Jun 22 2025

Dangerous heat continues well into the work week as the center of
the upper-level high slowly builds back towards the west and more
over Middle TN. This leads to a steady climb in high temperatures
through the week with highs peaking Wednesday. Current forecast
high at Nashville on Wednesday is 98 with model guidance showing
about a 50% chance that the high could hit the 100 degree mark.
Regardless, heat indices will be in the triple digits for most of
the area all week with the dominant high pressure.

By Friday and into the weekend, temperatures look to back off ever
so slightly as the center of the high is displaced south as an upper-
level trough tracks to the north. This also increases our chances
for rain and thunderstorms this weekend.

VFR conditions prevail this taf cycle with light and variable
winds. There is a 15-20% chance of a pop up thunderstorm impacting
CKV this afternoon. Due to low confidence in thunderstorm
development, no TS mention has been included in the taf.
