Thunderstorms with large hail and severe wind gusts will be possible Sunday afternoon and evening from parts of west Texas east-northeastward into the Ark-La-Tex. A marginal severe threat is expected to develop over parts of the eastern Gulf Coast. ...Southern Plains/Ark-La-Tex... At mid-levels, a shortwave trough is forecast to move southeastward through the central U.S. on Sunday, as a cold front advances southward across the southern Plains. South of the front, surface dewpoints mostly in the 60s F will contribute to moderate instability by afternoon from a dryline in west Texas east-northeastward across much of north-central and northeast Texas. As surface temperatures warm and low-level convergence increases near the front, scattered thunderstorms are expected to develop along the northern edge of the moist airmass during the afternoon and evening. Forecast soundings across parts of west and north-central Texas late Sunday afternoon suggest that MLCAPE will peak in the 2000 to 3500 J/kg range with 0-6 shear around 35 knots. This, combined with 700-500 mb lapse rates near 8 C/km, should be favorable for a large-hail threat. In addition, steep 0-3 km lapse rates should support an isolated wind-damage threat, especially if a cold pool can organize. The cold front position is expected to be a bit further south than is currently forecast. This projected position is in relatively good agreement with the most reliable guidance, which adds confidence in a potential severe threat area in west, north-central and northeast Texas Sunday afternoon and evening. ...Central and Eastern Gulf Coast... Westerly mid-level flow is forecast on Sunday across the Gulf Coast region. At the surface, a moist airmass will be in place from the central Gulf Coast eastward to Florida. Some solutions move a subtle shortwave trough eastward across the Southeast on Sunday. This would support isolated to scattered thunderstorm development in the afternoon near the coast from southeast Louisiana eastward to southern Georgia and northern Florida. Instability and deep-layer shear is expected to be strong enough for a marginal severe threat during the mid to late afternoon. ..Broyles.. 05/08/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
