.KEY MESSAGES...
Issued at 1249 AM CDT Mon Jul 27 2026

- Hazardous heat will continue in earnest through Wednesday with
  temperature maximums likely in the upper 90s/lower 100s and
  mostly dry conditions.

- A pattern change by the end of the week into the weekend will
  yield a return to near-normal summertime heat (mid-90s) and
  higher chances of rain.

.DISCUSSION...
Issued at 1249 AM CDT Mon Jul 27 2026

Hazardous heat will persist for the Ark-La-Tex over the next
several days as ridging continues to build back eastward across
the southern Great Plains. A recent, more persistent trend has
been for slightly stronger southeasterly winds across western
zones to more efficiently mix the atmosphere underneath the ridge
axis. This will preclude the most hazardous heat to east of I-49
for today, however, all areas will remain at risk of heat indices
at or over 105 degrees. Heat hazard product issuance is likely to
continue through this time period. Medium-range guidance suggests
some light at the end of this tunnel as ridging finally starts to
break down by the end of the week and the end of the month.
Synoptic- scale flow aloft will gain more of a meridional
orientation as a troughing pattern takes shape between Atlantic
ridging further to our east and Intermountain ridging to our west.
A return to normal summertime heat (mid-90s) is likely as a
result by this time with a coinciding increase in the potential
for productive rounds of convection to form in the afternoons with
daytime heating. Long- range guidance suggests an increasing
chance of a summertime frontal boundary that delivers even cooler
air and higher rain chances by the weekend (potential for lower
90s). Future forecast updates will resolve that potential relief
further.

Until then, fairly light southerly winds will still not offer much
relief. Dew points are expected to remain mostly in the upper
60s/low-to-mid 70s through the next several days. Heat indices
will range above 105 degrees as a result, and hazardous heat will
be impactful for all groups of people, not just heat-sensitive
groups. Precautions and awareness are encouraged to continue now
against the elevated potential for heat illnesses. This includes
(and is not limited to) altering outdoor plans, taking frequent
breaks if you must be outside, checking the backseat of your
vehicle, and knowing the signs and symptoms of heat exhaustion in
addition to heat stroke. /16/

(06Z TAFS)
Issued at 124 AM CDT Mon Jul 27 2026

VFR conditions should prevail across all terminal locations
through the next 24 hours. The only exception to this may be MVFR
VSBYs near sunrise at LFK but elsewhere, should not have any VSBY
concerns. Weak cu field will likely develop across our airspace by
mid to late morning with that cu field dissipating by late
afternoon into the evening hours.
