.UPDATE...
Issued at 642 PM CDT Tue Jun 23 2026

Pleasant conditions persist with overnight temperatures hanging in
the mid to low 60s. Calm winds will make way for patchy fog chances
overnight, though some cloud cover is possible. Temperatures
reach back up into the mid 80s tomorrow afternoon, with winds
remaining calm and no rain chances through tomorrow night.

.SHORT TERM...
(Rest of today through Wednesday)
Issued at 1132 AM CDT Tue Jun 23 2026

Pleasant weather is expected today with diurnal cumulus already
blooming on satellite this afternoon. With dewpoints in the 60s, it
certainly feels more tolerable outside compared to previous days, so
get outside and enjoy it. Highs today will be in the upper 70s to
low 80s and precipitation free, thankfully.

Tonight, our main focus is the dense fog we`re expecting to form.
Light winds and lows around our dewpoint are favorable for fog
formation across Middle Tennessee into Wednesday morning. Make sure
you plan your commute accordingly Wednesday morning, leaving ample
time to get to your destination and using your low beams if you
encounter areas of dense fog. Wednesday should be nice, albeit
cloudy. Not expecting any precipitation Wednesday either, with highs
in the low to mid 80s.

.LONG TERM...
(Wednesday Night through next Tuesday)
Issued at 1132 AM CDT Tue Jun 23 2026

A more zonal upper level pattern begins on Thursday, and with it
comes the heat. 850mb winds will turn more southwesterly, advecting
in heat to the mid-state. Highs through Saturday will gradually
creep into the upper 80s and low 90s. The more zonal pattern will
also lend to more rain chances into the weekend, as shortwaves can
easily pass through the area. Low to medium rain chances are
expected through Saturday, with QPF looking to be under an inch
total across the area. At this time, we`re not expecting any severe
weather with these shortwaves, but we will let you know if that
changes.

A high pressure system builds right over the southeastern United
States Sunday into Monday, intensifying the heat. Highs will stay in
the low to mid 90s, eventually building into the upper 90s, with
heat indices in the triple digits. Make sure you remember to stay
cool and take breaks in the AC or shade if you`re working outside.

.AVIATION...
(00Z TAFS)
Issued at 623 PM CDT Tue Jun 23 2026

The main issue for the taf period is the low to medium chance of
fog impacting the terminals after 06z. SRB/CSV have the highest
chances but fog at MQY/CKV is possible as well. Chances at BNA are
low but not zero. Any fog will mix out by 14z with VFR conditions
returning. Winds will be 5 kts or less for the taf period with
periods of variable wind direction.
