DISCUSSION

Issued at 241 PM CDT Wed Jun 24 2026

Persistent ridging over West Texas has been the primary driver to steer thunderstorm complexes across the Southern Plains into the Four State Region over the last several days. High-resolution guidance suggests another round of convection overnight across zones along and north of I-30. Afterward, this pattern finally begins to break down over the next 24-48 hours, with the lingering stationary front lifting away as a warm front and mid-level flow becoming quasi-zonal. Most of the additional rainfall left to fall this week is expected in south Arkansas. Ridging aloft is expected to redevelop in earnest overhead by Saturday with the coincident surface ridge across the Southeastern U.S. maintaining southerly surface winds.

This new synoptic setup will maximize warm air advection with temperature maximums in the low-to-mid 90s on Saturday, then mid- to-upper 90s on Monday. Long-range guidance currently gives a 60 to 70 percent chance of temperatures greater than 95 degrees by next Tuesday. With dew points expected to remain in the low-to-mid 70s by this time, hazardous heat will be impactful for all groups of people and not just heat-sensitive groups, likely prompting Heat Advisories by that time. Adequate precautions and awareness are encouraged 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 and heat stroke. /16/

AVIATION

(00Z TAFS) Issued at 636 PM CDT Wed Jun 24 2026

For the 25/00Z TAFs, VFR conditions will prevail through the majority of this forecast period. BKN to SCT decks of 4000 to 5000 ft will persist through much of the night, accompanied by BKN high clouds. Brief reductions to MVFR CIGs are possible near daybreak, most likely at KLFK, Scattered showers and thunderstorms may still move into our northern airspace this evening, but confidence does not merit including prevailing impacts to terminals at this time. Light and variable winds overnight will resume a southwesterly course during the day tomorrow at maximum sustained speeds of 5 to 10 kts with gusts of up to 20 kts possible.
