KEY MESSAGES

Issued at 1134 AM CDT Mon Jun 22 2026

- Flood Watch is in effect through for much of the ArkLaTex until 7 AM Wednesday morning.

- Temperatures will climb into the mid 90s by late week into the weekend possibly prompting Heat Advisory headlines each day.

DISCUSSION

Issued at 1119 AM CDT Tue Jun 23 2026

An upper-level disturbance to translate southeast from the Texas Panhandle and western Oklahoma into the ArkLaTex early this evening prompting another round of showers and thunderstorms within the ongoing Flood Watch area. With soils becoming nearly saturated across the region from previous periodic rain events over the past week or two, the flash flood thresholds are becoming much lower, resulting in flash flooding concerns with lesser rainfall rates. Thus, the ongoing Flash Flood Watch has been extended to 7 AM Wednesday morning to account for upcoming overnight convection.

Conditions are forecast to improve areawide on Wednesday afternoon, signaling a pattern shift characterized by hotter and drier conditions as an upper-level ridge builds east across Texas.

Although there may still remain a chance for diurnally driven showers and thunderstorms across portions of southwest Arkansas and southeast Oklahoma on Thursday afternoon, precip chances will become mostly non-existent through the weekend. Afternoon high temperatures will climb into the mid 90s areawide with heat index values exceeding 100 degrees, possibly approaching Heat Advisory criteria. /05/

AVIATION

(18Z TAFS) Issued at 1241 PM CDT Tue Jun 23 2026

VFR conditions are expected to prevail for much of the evening with southwesterly winds under 10 kts. There still is significant model uncertainty for early tomorrow morning. The expectation is that a line of showers and thunderstorms will move southeastward into the region and weaken into showers around daybreak. But there are model solutions where this line falls apart before making it into the area, which makes this period difficult to forecast. This package leans toward the former solution in assuming that the storms can hold together. Areas that see thunderstorms are likely to see some relatively higher cigs compared to the norm, but will see worse visibilities and stronger winds. Assuming this scenario plays out, thunderstorms will weaken and leave behind some showers for the late morning hours before beginning to clear by the end of this period. /57/
