DISCUSSION

Issued at 1204 PM CDT Mon Jun 22 2026

Convective complex from earlier today is forecast to continue to shift southeast across portions of north Louisiana. Any convection that will be able to redevelop this afternoon into this evening will be along a weak east/west oriented frontal boundary lingering across the region. Timing on late day convection will depend on the amount of diurnal heating that can be generated this afternoon along with the ability for the atmosphere to recover from earlier storms. There is a slight risk for severe thunderstorms across portions of south-central Arkansas this afternoon as an upper- trough exits the region to the east. Severe threat should be short lived as convection moves downstream across Mississippi into Tennessee.

Low-level jet to increase this evening allowing for convergence along the lingering frontal boundary stretched across the region. Rain rates to increase with ongoing convection along the front. With mid-level flow roughly paralleling the boundary, could see training storms capable of producing flash flooding with 1 to 3 inches of rainfall along with isolated higher amounts possible. Thus,a Flood Watch has been issued for this afternoon into the overnight hours across much of the ArkLaTex due to the threat of flash flooding.

Another round of strong convection will again be possible late Tuesday night into Wednesday across portions of mainly southeast Oklahoma and south Arkansas with locally heavy rain and gusty winds being the main threats.

From Wednesday afternoon onward, upper-level ridge to begin to build eastward allowing for a gradual drying trend across the ArkLaTex. However, with increased ridging, high temperatures to soar into the mid 90s by the end of the workweek into the weekend with heat index values approaching Heat Advisory criteria each day. /05/

AVIATION

(18Z TAFS) Issued at 1234 PM CDT Mon Jun 22 2026

VFR conditions prevail for all sites this period. The frontal boundary that acted as the focus for this morning's thunderstorms is still present and is expected to spark redevelopment this afternoon and evening. Locations are still uncertain, but sites along and north of I-20 can expect at least VCTS for an extended period of time due to the limited movement of this front. Expect occasionally deteriorating conditions with these showers and thunderstorms through early tomorrow morning. Cigs will lower to MVFR closer to daybreak Tuesday, with some spots possibly falling to IFR/LIFR. Another round of showers and thunderstorms could initiate along this same boundary tomorrow, but that is significantly more uncertain right now. /57/
