What forecasters said that day

The local office's own words before this excessive heat warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Jackson, MS wrote its last area forecast discussion before this excessive heat warning went out at Jul 27, 12:25 PM CDT, 2 hours 29 minutes earlier.

Area forecast discussion, Jul 27, 12:25 PM CDT, 2 hours 29 minutes before
Area Forecast Discussion
National Weather Service Jackson MS
1225 PM CDT Tue Jul 27 2021

.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion:

VFR conditions will prevail at all terminals through the period. A
scattered cumulus deck will continue to develop this afternoon
with the main focus being another round of afternoon to early
evening scattered showers and thunderstorms. Brief reductions in
visibility and ceiling are likely with any of these storms that
impact airfields. TAF amendments will be utilized as storms
develop if any impacts are expected. Otherwise, storms should
gradually dissipate by 28/06z with broken to scattered high clouds
overnight. MVFR to IFR visibilities from fog cannot be completely
ruled out during the morning hours, but will leave out of the TAF
for now given low confidence in timing/placement. /TW/

&&

.DISCUSSION...

Stout upper ridging extending from the Central Plains into the
Lower Mississippi Valley will remain in place today. This will
continue to support hot and humid conditions across the area with
heat index values surging into the 105-110 degree range for much
of the area. The ongoing heat advisory is well placed and no
adjustments were needed. Scattered afternoon showers and
thunderstorms will also be possible, however, near moist adiabatic
lapse rates and a lack of sufficient DCAPE will preclude the
potential for severe weather. Otherwise, the ongoing forecast
remains on track and only minor changes were needed. /TW/

Prior discussion below:

Today and Tonight...

There is no doubt about it that dangerous heat conditions will
continue on today. A surface high pressure stretching from the west
across to the Deep South will remain in control today. Diurnally
driven afternoon showers and storms will also be the case and any
rain we get, can add on to the already muggy conditions we've been
experiencing these last several days. Even with the showers and
storms we've seen these last couple of days, we've managed to exceed
expectations in regards to heating. Dewpoints will remain in the
mid to upper 70s causing increased humidity and combined with high
temperatures climbing into the mid 90s, another hot summer day
can be expected. Heat indices could reach up to 110F for a long
duration of time and with conditions unchanging, have gone ahead
and added additional northeast counties to the current 'Heat
Advisory' including a line from Attala to Noxubee and everywhere
north of there. The 'Heat Advisory' goes into effect at 10AM and
will last until 7PM this evening. The dangerous heat is also being
advertised in our HWO with an 'Elevated risk' covering areas
under the heat advisory and a 'Limited Risk' covering the
remaining counties who might not reach our heat advisory criteria
but could still see heat indices reach near 105F.

Depending on how early rain and storms kick off, some counties might
not reach the advisory criteria and if that happens, new assessments
will go underway and the advisory will be adjusted as needed but
until then, will keep what's in place. Most activity should
diminish as we start to lose day time heating during the early
evening hours but a few showers and a storm or two could linger
into the night. Muggy conditions will continue tonight as lows
only drop into the mid to upper 70s. Heat can be very dangerous so
it is suggested that outside work/play is limited, to drink
plenty of fluids and to stay in cool places!/JNE/

Wednesday through Monday...

Very hot conditions will develop at mid to late week over much of
the area, especially over the ArkLaMiss Delta region. Building
mid/upper level ridge axis from the Central Plains into the
MidSouth looks to keep most convective chances over the far south
during the mid to late week timeframe. Meanwhile over the north,
increasing warmth aloft will limit diurnal convective chances
allowing lots of sun and strong evaporation to occur of the
continued moist soil from recent rains. This will result in
dewpoints remaining in the mid to upper 70s through the max mixing
part of the day. With afternoon maxes in the mid to upper 90s and
dewpoints remaining in the mid to upper 70s, maximum heat indices
of 105-110 will be common with values from 110-115 possible over
portions of the ArkLaMiss Delta where excessive heat warnings may
become necessary Wednesday into Saturday.

Thereafter, a digging mid/upper level trough over the northeast will
begin to squash the ridge axis to the south allowing better
northwesterly flow and better convective chances Sunday into
Monday./GG/
