DISCUSSION

Issued at 1148 PM CDT Mon Sep 21 2026

This evening's convection has at last dissipated, with quiet and mild conditions to persist overnight as lows drop into the upper 60s north to lower 70s south. Synoptic scale guidance continues to depict ridging reasserting itself over eastern Texas and setting up shop over the ArkLaTex. Despite the implied subsidence of such a feature, short range high resolution guidance resolves some isolated to scattered showers across the southern ArkLaTex during the afternoon hours Tuesday. Given the similar overperformance this afternoon, elected to increase PoPs along and south of the I-20 corridor between 18Z and 00Z. Coverage of anything that develops will most likely be limited and short-lived.

Through the rest of the week, ridging will remain locked in place and very much shuts out any further rainfall chances. With the ridge axis directly overhead, the only real uncertainty at this point is the extent to which our advertised cooling trend (to temperatures which are less ridiculously above average) actually develops. Our Arkansas counties still look to enjoy some afternoons of highs in the upper 80s late this week, but south and west, the so-called cooling will be less pronounced. That being said, highs in the lower 90s are at least a step in the right direction. Lows will likewise trend downward, with sites areawide waking up to temperatures in the 60s by Friday and Saturday morning. With dry air filtering in, low relative humidity values in conjunction with very dry antecedent conditions may result in returning fire weather conditions late in the week.

By this weekend, the ridging will recede to the south and west, making room for an upper level trough to ride the northwest flow into the ArkLaTex Sunday, lingering over the middle Mississippi Valley into early next week. Scattered showers look to return to our northeastern zones Sunday, with lower-end chances becoming more widespread into the new work week. A more pronounced trough digs south across the Plains, bringing higher chances of showers and storms next Tuesday. Temperatures will meanwhile warm slightly, with highs returning to the 90s and lows to the upper 60s and lower 70s.

AVIATION

(06Z TAFS) Issued at 1217 AM CDT Tue Sep 22 2026

For the 22/06Z TAF period, VFR conditions are expected through the majority of the period as a lingering frontal boundary continues to slowly advance southward through our airspace. Patchy fog may develop briefly toward daybreak so have maintained tempo MVFR vsby restrictions at most sites early in the period. Otherwise, expect some convective redevelopment with daytime heating later on today before the front eventually clears the region. Therefore, opted to mention VCTS once again this afternoon at a few sites to account for this possibility. Light and variable winds overnight and early this morning will trend more N/NE with fropa, averaging between 5-10 kts.
