.SHORT TERM...
(Rest of today through Monday)
Issued at 1130 AM CDT Sun Jul 19 2026

Today's chosen area of morning convective initiation is south of I-
40, with cumulus fields bubbling well on satellite in that area and
beginning to bubble north of I-40 as well. High temperatures will
get into the mid 80s to low 90s for highs today, with heat indices
in the triple digits especially west of the Plateau.

While we are not in a severe risk area today, we are still expecting
thunderstorms in Middle Tennessee. Some guidance is showing an
organized storm cluster forming near the TN/AL state line tonight
and continuing into Alabama, whereas other guidance is not showing
anything more than the pop-up showers and thunderstorms we've grown
accustomed to. Guidance seems to do better once we have more
widespread initiation, so we will see what is spit out when storms
form. Not expecting severe weather today, but some stronger storms
are possible. As usual, main hazards continue to be gusty winds and
heavy rainfall that could result in localized flash flooding with
stronger storms.

As for Monday, highs will be more widespread in the 90s, even in
some areas of the Plateau. While we will continue to see an increase
in heat indices to start the work week, spots meeting and exceeding
heat advisory criteria will be more isolated in Middle Tennessee
compared to other areas. This leads us to forgo a heat product, at
least for Monday. Rain wise, popcorn convection will continue on
Monday in the scattered fashion we have seen lately. The atmosphere
is chock full of moisture right now, and that's the way it will stay
through mid-week.

&&

.LONG TERM...
(Monday Night through next Sunday)
Issued at 1130 AM CDT Sun Jul 19 2026

The beginning and middle of the work weeks are a bit complicated
with multiple hazards at the same time. Tuesday into Wednesday, a
500mb trough and accompanying low pressure system will swing through
Ontario, dragging behind them the cold front we will see Tuesday
night into Wednesday. This will bring us some forcing and not
surprisingly, a risk for severe weather. SPC has seen this setup in
the guidance and put us in a Day 3 slight risk (level 2 out of 5)
for severe weather. As it stands now, damaging winds continue their
streak of being a popular hazard with our severe chances this
summer. There appears to be a low end tornado threat in CAMs with
this system, with a linear storm mode to boot. Something we will
have to keep an eye on in future forecast packages. In addition to
the severe risk, heat indices will be dangerously high on Tuesday,
exceeding 105 in quite a few areas west of the plateau.

After the cold front, we will enter a quieter period for the mid-
week. Highs will be in the mid 80s starting on Wednesday, slowly
warming back into the 90s into next weekend. It does look like we
could see another system Friday into Friday night associated with a
shortwave in the mid-levels, but specifics are not too clear on that
system just yet.

.AVIATION...
(18Z TAFS)
Issued at 1228 PM CDT Sun Jul 19 2026

Scattered storms have once again developed across Middle Tennessee
with medium chances of impacting CSV/SRB and low to medium chances
of impacting BNA/MQY/CKV through the afternoon. Activity will
decrease after 00z. Areas of fog are expected to develop after 06z
with medium to high chances of dropping vis to IFR/MVFR at
CSV/SRB/CKV. Confidence is lower at BNA/MQY, so VFR conditions
were maintained. PROB30 was not included at BNA for Monday as
storm coverage is expected to be lower. Winds will generally
remain around 5 kts or less for the forecast period shifting from
the WNW to the SSW overnight and into Monday morning.
