DISCUSSION

Issued at 154 PM CDT Fri Jun 19 2026

An active morning across the region, as a shift in our synoptic pattern has resulted in widespread rainfall over the area. Upper ridging as settled over the Southwest CONUS into western Texas. As result, we have transition to a northwesterly flow aloft pattern, with a long wave trough draped from Southern Oklahoma into extreme northern Louisiana. A potent short-wave moved along the flow this morning, producing a MCS. Ahead of that MCS, showers and thunderstorms developed along the aforementioned long-wave trough. That MCS pushed moved along the long-wave trough, producing heavy rainfall across extreme northeast Texas and adjacent southern Arkansas. This prompted a Flash Flood Watch to be issued for most of the region along and north of I-20 through 7 pm this evening, along with a few warnings, as some locations were reporting 2" hourly rainfall rates. Earlier progs had more widespread and robust convection down to the I-20 corridor, but that didn't quite materialize. Even so, will keep the current watch in place for continuity, and because of the heavier rainfall on the northern end of the watch this morning. Also, with another short-wave still lingering back across north-central Texas, some additional convection is possible through this evening. Elsewhere, a Heat Advisory remains in place, generally for all portions of the forecast area south of I-20. We have seen heat index values reach the 105 degree threshold within the advisory today, but convection is staring to develop in those areas this afternoon, which should cool temperatures and drop heat indices.

The other short-wave trough across north-central Texas will slowly move eastward across the region overnight through Saturday. This will ignite additional convection throughout this period, along with more locally heavy rainall. The Weather Prediction Center has a Slight Risk for Excessive rainfall over a large portion of the region Saturday. Also, some isolated damaging wind gusts can't be ruled out in the stronger convection. Models are trending drier on Sunday, but some rain chances will remain, as another disturbance moves across the region.

On Monday, the upper ridge over the Southwest CONUS will flatten out and expand eastward into the Southern Plains and Lower Mississippi Valley. The northwesterly flow will become more zonal and shift north of I-20 into our extreme northern zones. Rain chances will remain for areas along and north of I-20 Monday. Additional heat advisories could be needed, mainly south of I-20, where the the lack of rain will allow temperatures to climb into the mid 90s. The ridge will retrograde back into the SW CONUS by Tuesday and remain through the end of the work week. This will bring a return of northwest flow with embedded disturbances and returning rain chances. Drought conditions should continue to improve across the area, but we could see flooding concerns going forward. /20/
