What happened

The episode as NWS FWD wrote it up.

The start of what would be one of the hottest summer months on record began in July. North and Central Texas experienced above average temperatures from July 10 through the end of the month. Several prolonged Heat Advisories were in effect, and at times Excessive Heat Warnings were needed. The average temperature for the month of July ranked in the Top 10 warmest for climate sites in both North and Central Texas. However, it was the month of August that really tipped the average temperature for the summer season into the Top 5. Unfortunately several fatalities were reported in the DFW Metroplex related to heat.

What forecasters said that day

...New Aviation, Short Term...

.SHORT TERM... /NEW/
Update:
Elevated convection continues to fire in a line oriented from
Montague county through Rains county. These cells are a result of
moist ascent over a stalled front currently across Central Texas.
A general weakening trend will occur after sunrise as the cells
move southeast. Some additional showers and storms may develop
closer to the front this afternoon across Central Texas.

Otherwise, it will be mostly sunny and hot today with highs in the
90s to around or just above 100. The only exception will be across
the northeast zones where clouds will linger, keeping high
temperatures in the middle and upper 80s. We will leave the
current Heat Advisory as is for now and allow the next shift
decide its fate beyond today.

Still expecting convection to move in from the west this evening
and overnight with the best chance of storms north of the I-20
corridor.

No major changes were made to the previous forecast package with
this update.

Previous Discussion:
/Through Monday Night/

A welcomed summer cold front continued moving south through
Central Texas late this evening. Temperatures north of the front
were already in the 70s and lower 80s as of 10 PM with mainly
middle and upper 80s south of the front. Overnight lows will cool
into the 70s region-wide with even a few upper 60s possible
across the north.

After a quiet evening, showers and storms will continue to
develop through the night with increasing return flow over the
front. Storm coverage will be scattered, especially near and north
of the I-20 corridor. Showers and storms will be possible through
the morning hours Monday but should finally weaken or move to the
east by midday with the loss of the nocturnal LLJ. The front is
progged to lift slowly northward Monday afternoon. Weak moisture
convergence on the lifting front and strong large scale subsidence
provided by the ridge to the west should prevent any new storms
from developing during the afternoon.

Highs Monday will be hot once again across Central Texas with
upper 90s to near 103. Lower and middle 90s are expected across
the remainder of the forecast area, except for the northeast where
temps will struggle to get out of the 80s. We will leave the
current Heat Advisory south of the I-20 corridor through Monday
but it will likely need to be expanded northward later in the
week.

A weak shortwave will move around the northeastern periphery of
the ridge to the west Monday afternoon, resulting in scattered
thunderstorms across West Texas. These storms will likely
organize into a complex as they move east Monday night. The best
storm chances will be generally north of the I-20 corridor. A few
strong to severe storms will be possible with damaging winds
being the primary hazard.

.LONG TERM... /Issued 334 AM CDT Mon Jul 10 2023/
/Tuesday through Sunday/

Scattered convection from the overnight complex moving in from
the west should be ongoing across mainly North Texas on Tuesday
morning. Much of this activity will weaken after sunrise, but a
few of the high res models do advertise a lingering MCV over the
region which may spark new convection later in the day and
farther south into Central Texas. As a result low PoPs will be
advertised over most of the CWA, but the best chances will be over
the northeast zones and early in the day. The additional clouds
and potential rain-cooled air means high temps will be near normal
for most of the region, but humidity will be higher than Sunday
and today, so max heat indices will range from 105 to 110 over
most of the area. The heat advisory will likely be expanded.

The upper level ridge will build into the region from the west on
Wednesday and there are no indications of any convection forming
upstream over West Texas and the High Plains. This means our
chances of rain will end for a few days, while strong subsidence
results in a warming thermal profile with some slight drying.
High temps will jump to above 105 degrees over the western zones
Wednesday, near 100 along the I-35 corridor, and upper 90s in the
east. Temps will climb a degree or two more on Thursday. Heat
indices will continue to range from 105 to 110, with some spotty
areas eclipsing 110. Meanwhile southerly winds are forecast to
increase midweek into the 10 to 20 mph range, which will take
some of the edge off of the daytime heat. However, in part due to
these winds, low temps will be unseasonably warm in the upper 70s
to lower 80s. The increased winds will also enhance the wildfire
danger, especially west of I-35 where air temps above 105 will
result in minimum RH in the 20s.

The upper ridge will weaken by late in the week so we will see
some subtle cooling. Models today have backed off a bit on the
prospects for a weak cold front and chances of rain next weekend.
Instead most of the ensemble members are keeping this just to our
north. Some low PoPs are advertised along the Red River Saturday
night into Sunday, but otherwise will show a dry and continued hot
forecast for most of the region.

.AVIATION... /NEW/
/12Z TAFs/
The main aviation concern with this TAF package will be
scattered storms this morning and evening/overnight storms. The
convection this morning is a result of moist ascent over a stalled
front across Central Texas. Although a storm or two could briefly
reach DAL or DFW over the next couple of hours, VCTS at all the
metroplex TAF sites should be sufficient based on current coverage
and movement. Storms should dissipate a few hours after sunrise
and no additional storms are expected until a complex of storms
arrives from the west overnight.

Scattered to broken middle and upper level clouds associated with
the morning storms will linger through much of the day with few to
scattered Cu between 3500 and 5000 ft. Clouds will likely clear
in the early to mid evening hours but increase in coverage overnight
with the approach and eventual arrival of the storms from the
west.

An east to southeast wind will prevail through Tuesday morning at
speeds generally less than 12 knots.
