What happened

The episode as NWS SHV wrote it up.

An expansive upper level ridge spanning much of the Southern U.S. in early July led to consecutive days of abnormally hot temperatures across all of the Four State Region, with daytime temperatures climbing into the mid and upper 90s to lower 100s each afternoon. Wet soils from near widespread rains back on the 2nd-3rd also did not allow for much mixing of dew points, with oppressively hot conditions observed as heat indices ranged from 105-109 degrees each day during the peak heating hours.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Jul 4, 10:03 AM CST, 57 minutes earlier.

.SHORT TERM...
(This afternoon through Tuesday)
Issued at 1049 AM CDT Mon Jul 4 2022

The morning water vapor imagery indicates that upper level ridging
has built in over the center of the region into Lower MS Valley,
although a weak shear axis, remnant from the tropical low that
affected the region this past weekend, is situated from SE AR/far
NE LA into Wrn and Srn MS. In fact, the morning visible satellite
imagery depicts areas of ACCAS has developed near this shear axis
over these areas, even resulting in isolated convection over NW
MS just E of the MS River. The morning progs indicate that the
ridge may begin to drift W and N through the afternoon, with
strong heating within a high PW environment characteristic of
1.8-2.0+ inches over these areas near this shear axis to focus
isolated convection during the afternoon. Have maintained slight
chance pops for the afternoon, with a very hot and dry forecast
expected elsewhere as strong subsidence results in temps climbing
into the upper 90s/in excess of 100 degrees over much of the
region. Only minimal changes were needed to the max temp
forecast, mainly to bump temps up a degree or so across the Ern
zones given the 10am readings near 90. Also beefed up the sky
grids to reflect the AC present along the shear axis, as well as
the cu field which should expand more NNE across much of the
region this afternoon. With only limited mixing expected today,
heat indices are expected to range from 105-110 degrees across the
area, where the Heat Advisory is currently in place. Otherwise,
the remainder of the forecast is on track.

Zone update already out...grids will be available shortly.

.LONG TERM...
(Tuesday Night through Monday)
Issued at 327 AM CDT Mon Jul 4 2022

A large upper level ridge will remain in place across the Southern
Plains and Lower Mississippi Valley by Wednesday, and continuing
through Friday of the upcoming work week. Above normal temperatures
should continue, with afternoon highs generally in the upper 90s to
triple digits in many locations, especially across the western half
of the region. There may be enough weakness on the southern and
eastern flank of the ridge to allow some diurnal marine convection
to make it into portions of our Central and NE Louisiana zones
during the afternoon hours, but confidence only remains high enough
to include slight chance POPs at this time. Because of this, those
areas could see afternoon temps closer to the mid 90s. Heat
Advisories are likely during this time, as models suggest this
stagnant airmass will keep dewpoints in the upper 60s to mid 70s
range. This would result in heat index values approaching and likely
exceeding the 105 degree threshold.

By next weekend and into the first portion of next week, the center
of the upper ridge will start to shift westward into portions of
western Texas and eventually into the Rockies. However, the above
normal temperatures and possible heat advisories will remain,
including some triple digit readings.  However, because of the
placement of the ridge, there could be enough weakness for isolated
diurnal convection to develop and increase in coverage, mainly
across our eastern zones on Saturday. Could see more widespread
convection on Sunday and possibly Monday, as a weak frontal boundary
moves into the region.

.AVIATION...
(12Z TAFS)
Issued at 635 AM CDT Mon Jul 4 2022

Starting with mostly VFR conditions across our airspace attm. The
exception is up and down local VSBY restrictions at the ELD
terminal and some increasing MVFR/IFR ceilings trying to move
northward towards the LFK terminal. These issues should be brief
this morning with VFR conditions overall prevailing through the
day across our airspace. Look for a developing cu field across our
region today with that cloud cover likely dissipating by this
evening. VFR conditions should prevail through the overnight hours
with the exception of some VSBY restrictions late tonight once
again, mainly at the ELD terminal.

This Hazardous Weather Outlook is for south central Arkansas,
southwest Arkansas, north central Louisiana, northwest Louisiana,
southeast Oklahoma, east Texas and northeast Texas.

.DAY ONE...Today and tonight.

...HEAT ADVISORY IN EFFECT FROM 11 AM THIS MORNING TO 7 PM CDT THIS
EVENING...

Upper level ridging will begin building in over the region today.
Afternoon temperatures will likely range from the mid 90s to upper
90s, with 100 degree temperatures possible across East Texas and
Northwest Louisiana. Combined with the high humidity, heat indices
will likely reach the heat advisory range of 105 to 110 degrees this
afternoon.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.

Upper level ridging will persist through much of this upcoming week.
Afternoon temperatures will likely range from the mid 90s to in
excess of 100 degrees each day. Heat advisories are very possible,
as temperatures combined with the high humidity, will likely result
in heat indices ranging from 105 to 110 degrees for much of the Four
State Region. Slight chances for afternoon isolated showers and
thunderstorms will remain across the southern and eastern sections of
the region during the upcoming work week. This could expand to the
remainder of the area by next weekend, as a weak frontal boundary
moves into the region.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel, amateur radio
operators, and storm spotters will not be needed through tonight.
