DISCUSSION

Issued at 1217 AM CDT Wed Jun 24 2026

Showers and thunderstorms seen across the northern half of the region this evening are starting to clear the area to the east, with some lingering light showers across northeast Louisiana and south central Arkansas. Gradually this moisture will come to an end and we will see a short couple of hours with no precipitation, followed by another round of showers and thunderstorms towards sunrise. This activity will linger into the early to mid afternoon hours before starting to diminish, although we could still see some lingering showers into Wednesday evening. Thinking the best chances will be along and northeast of a line from Mount Pleasant, TX to Shreveport LA, to Natchitoches, LA. Some of these storms will be capable of producing heavy rain, with some training possible. With the current trends pointing that precipitation will be ongoing through the morning hours, I have extended the Flood Watch out through 18z on Wednesday. With the amount of moisture this area has received over the past week, it won't take much to bring on flooding concerns.

To some this might come as a sigh of relief, while others will dread this news, but once the last rain drop falls on Wednesday, the sauna cranks the dial and steals the show heading into the end of the week. Should the forecast remain true, meaning the end of precipitation as we know it for the foreseeable future (after Wednesday), temperatures will quickly start to climb starting on Thursday as an upper-level ridge begins to build into the region. Thursday will see highs range from the upper 80s across our northern zones to the upper 90s across our southern zones. Similar conditions are expected on Friday, but the 90s return to the entire region on Saturday and will be the mid to upper 90s by the start of next week. While these temperatures appear to be manageable, considering the relatively "cool" June, add in the humidity and we are looking at heat index values in the lower to mid 100s by Friday. The values increase to around 105 to 110 as early as Sunday and then linger here for Monday and Tuesday. As such, heat headlines will likely be needed heading into the weekend and into the start of next week. All it takes is a wave of scorching heat to make us truly miss the rainy days we sometimes take for granted. /33/

AVIATION

(06Z TAFS) Issued at 102 AM CDT Wed Jun 24 2026

The leading edge of the deeper convection has just exited MLU as of 0545Z, with areas of -RA and mostly VFR cigs expected to linger across Srn AR/NCntrl/NE LA through 08-10Z before diminishing. VFR conditions should persist elsewhere through much of the overnight hours beneath some residual convective debris, although patchy IFR/LIFR cigs should develop over SE OK/SW AR and possibly extreme Nrn LA between 09-12Z once the elevated cigs begin to thin. Should also see scattered convection redevelop overnight across portions of SE OK/SW AR and portions of extreme Nrn LA, where VCSH was inserted for the N LA/SW AR terminals. Additional low MVFR cigs should develop after 12Z farther WSW across E TX, but quickly lift/scatter out by mid to late morning. However, cigs will be slower to lift/return to VFR across Srn AR/NE LA where scattered convection may linger through the afternoon hours. The cu field should diminish by/shortly after 00Z except across Srn AR, with VFR conditions persisting through much of the overnight hours Thursday morning. Lt/Vrb winds overnight, except S winds around 5kts across E TX, will become SSW 5-10kts after 15Z, except remain Vrb around 5kts across Srn AR. /15/
