KEY MESSAGES

Issued at 12:42 PM CDT Mon Jun 15 2026

- Additional shower and thunderstorm redevelopment and the threat for heavy rainfall and localized flash flooding is expected late tonight over these same areas, persisting through the afternoon Tuesday before diminishing from northwest to southeast during the afternoon.

- An additional threat for heavy rainfall and flash flooding may rematerializes over portions of Deep East Texas and North Louisiana Thursday.

- Further rain could impact the area on Friday into Saturday, but there is still some uncertainty this far out.

DISCUSSION

Issued at 1242 PM CDT Mon Jun 15 2026

The stationary front has stalled around the I-20 corridor from northern Rusk Co, TX eastward. Areas along and south of this front have seen continuous rainfall this morning, with areas seeing close to 3 in/hour rain rates with some of these showers. The D1 ERO has been updated to include our southern zones in a moderate risk with this increase in heavy showers. It should be noted that this short-term concern is mainly due to the heavy rainfall rates as opposed to the total accumulations. Near-record PWATs have been observed and will lead to very efficient rain producers. Soils that are too dry can be somewhat hydrophobic and unable to quickly absorb heavy rain. This will lead to locally considerable flooding today. At the time of writing, a few LA mesonet sites have recorded almost 4 in of rain over the last few hours with more to come. There have also already been reports of stalled vehicles in flood waters. The longer this rain event continues, the more you will see concerns over flooding from training storms and saturated soils.

Showers are expected to continue south of I-30 overnight tonight and reintensify during the day tomorrow. The current D2 ERO has our forecast area in a slight risk, but could be upgraded to moderate based on the rainfall observations from today's rain. We may see a brief break in the rain on Wednesday for most of the region as the stationary boundary acting as a lifting mechanism will be able to move out of the region late Tuesday evening. NBM still has some PoPs along our southern and eastern boundaries during the day, but it shouldn't be enough for more flooding. The break in rain will allow temperatures in the northern half of the region to approach 90 again. Areas to the southeast are expected to stay in the mid to upper 80s with the rain and continued cloud cover.

Rain chances on Thursday are increasing due to the area of low pressure potentially moving in from the Gulf. The GFS is beginning to align more with the ECMWF on timing of the low pressure and increasing confidence of returning heavy rainfall. The D4 ERO already includes parts of north central LA in a moderate, with areas south of I-30 in a slight. Soils will be plenty saturated with days of heavy rainfall at that point, making widespread flooding a concern. Mid to long range models are suggesting that an upper-level low could move southeast through the Ark-La-Tx on Friday. This could bring even more rain to the region and extend the potential for flooding into the weekend. But there is still uncertainty on this, especially if the low pressure in the Gulf interacts with the larger upper-level flow differently than expected.

AVIATION

(00Z TAFS) Issued at 749 PM CDT Mon Jun 15 2026

For the 16/00Z TAF period, MVFR/IFR cigs continue to plague most terminals across our airspace this evening and this trend will continue overnight as a stalled front near I-20 is expected to lift back north on Tuesday. South of the front, convection will ramp back up once again on Tuesday as heating will enhance more showers and thunderstorms through the afternoon, mainly south of I-20. In the meantime, some patchy light rain will persist this evening and overnight with cigs dropping further into IFR/LIFR range along with some patchy dense fog becoming more likely closer to daybreak. Light and variable winds will prevail throughout much of the period before trending more southerly as the front retreats farther north later on Tuesday.
