An Enhanced Risk for severe thunderstorms exists across northeast Texas, southeast Oklahoma, and adjacent counties in southwest Arkansas while a Slight Risk of severe storms extends across Deep East Texas, northwest Louisiana, and south Arkansas for this afternoon. Additionally, there is a Flood Watch in effect from this morning through overnight tonight across the I-30 corridor and points northward.
An upper-low across the Desert Southwest is forecast to swing east into the Texas Panhandle today. Instability will increase as the upper-low approaches a surface low embedded within a frontal boundary extending from northeast Texas into Oklahoma and Missouri with showers and thunderstorms forecast to develop at the time of peak heating. Dewpoint values in upper 60s in the warm sector south and east of the front will further aid in destabilizing the atmosphere ahead of the upper-low. Damaging winds, tornadoes, large hail and flash flooding may be possible as storms become supercellular with large hail being the initial threat. Convection may evolve into an MCS by early to mid-evening resulting in an all threats scenario.
Conditions to gradually improve through the overnight hours as the surface and upper-low swing east into Missouri.
A Slight Risk for severe weather is possible again on Thursday afternoon across most of the ArkLaTex. A remnant frontal boundary across the region, combined with an upper-level disturbance translating east within the mean zonal flow pattern aloft, will allow for convection to develop during the afternoon hours with damaging winds being the main threat. /05/
LONG TERM
(Thursday Night through Wednesday)
Issued at 1247 AM CDT Wed Apr 30 2025
A lingering frontal boundary across the region will serve as the focus for convection on Friday into Friday evening as a longwave upper-trough swings southeast across the mid-CONUS. As the upper- trough pushes into the Appalachians, ridging to build from the west bringing dry conditions to the ArkLaTex from Saturday through Monday night. At the surface, high pressure building across the region will allow for cooler temperatures with low temperatures early next week ranging from lows in the 50s to highs in the upper 70s to around 80 degrees. Otherwise, could see showers and thunderstorms returning to east and northeast Texas on Tuesday as the surface high and upper-ridge shift east. /05/
AVIATION
(12Z TAFS)
Issued at 627 AM CDT Wed Apr 30 2025
For the 30/12Z TAFs, conditions will continue to deteriorate through the coming hours, as IFR/MVFR CIGs overspread ArkLaTex airspace. Showers and storms look to begin to impact the region into the morning, largely remaining north of the I-30 corridor, with visibility impacts to KTXK possible as the day continues.
Storms will become more widespread into the afternoon across the region, with locally heavy rainfall leading to VSBY reductions and related severe impacts possible, primarily gusty winds, as well as hail and tornadoes. Southerly winds will pick up during the day to maximum sustained speeds of 10 to 15 kts with gusts of 15 to 25 kts possible, and locally higher values in the vicinity of stronger storms.
