.SHORT TERM...
(Rest of today through Sunday)
Issued at 1125 AM CDT Sat Jul 5 2025

Satellite showing clear skies once again across middle Tennessee.
The weekend should be fairly quiet, with some chances for isolated
showers and thunderstorms both days. This is due to moisture return
increasing with southerly flow into the mid-south. This will lead to
triple digit heat indices starting today and going into next week,
though we are expecting them to remain below advisory criteria. This
morning`s sounding showed 1.5" for Precipitable Water. That`s an
increase of half an inch of precipitable water compared to yesterday
morning`s sounding, so the moisture return has begun. With any
diurnally driven thunderstorms, main hazards will be gusty winds and
heavy rainfall.

.LONG TERM...
(Sunday Night through next Saturday)
Issued at 1125 AM CDT Sat Jul 5 2025

Mid-level troughing will drop south into the work week, allowing
disturbances to have more of an effect on middle Tennessee through
the mid week. A ridge in the desert SW will then flatten, allowing
the trough to dip further south at the end of the work week. With
further moisture advection into the area (PWATs mid week are up to
1.8" in the guidance) and these disturbances traversing across the
Ohio Valley then across the state, showers and thunderstorms become
increasingly likely through the remainder of the period. With the
usual caveat of precipitation amounts being higher in thunderstorms,
daily accumulations look pretty light right now each day in the work
week. Total accumulations through the work week are around half an
inch to just over one inch, with a 20 - 40% chance of accumulations
greater than 1". Compared to previous guidance, there seems to be
more of a focus on northern middle TN for the area most likely to
receive over an inch.

As for temperatures, they will return to near normal, which is still
in the upper 80s and 90s. Heat indices will be a concern through mid-
week as well, with triple digit heat indices possible every day
through Wednesday.

.AVIATION...
(12Z TAFS)
Issued at 607 AM CDT Sat Jul 5 2025

Fog has developed across the area, with MVFR and IFR vis popping
up at all terminals this morning. Fog should burn off over the
next hour or two, then expecting VFR conditions. Southerly winds
around 5 knots expected during the daytime hours, becoming light
and variable overnight. Low chance for isolated showers and storms
this afternoon, and confidence not high enough on location to put
into the forecast.
