Thunderstorms are possible across parts of Deep South Texas and the Texas Gulf Coast on Saturday. Severe potential appears low at this time. ....Synopsis... A positive-tilt upper-level trough is forecast to extend from the Great Lakes southwestward into the central/southern High Plains Saturday morning. The large-scale trough and multiple embedded shortwaves will move east-southeastward through the day. Dry and stable conditions in the wake of an earlier cold frontal passage will result in negligible thunderstorm potential across most of the CONUS. One exception is across parts of the TX Gulf Coast and Deep South Texas, where the southernmost embedded shortwave trough may impinge on modest low-level moisture return, resulting in at least isolated thunderstorm potential. ....TX Gulf Coast into Deep South TX... Guidance continues to vary regarding the magnitude of inland low-level moisture return on Saturday. Recent GFS solutions remain somewhat more aggressive compared to other guidance, with 60s F dewpoints spreading across parts of the TX Gulf Coast and Deep South TX during the afternoon. This scenario could result in some potential for organized storms near a southward-moving cold front, in the presence of strengthening deep-layer shear. Other guidance is generally less aggressive with inland moisture return, keeping stronger instability and the bulk of deep convection offshore. Uncertainty regarding the development of sufficient instability is too high for severe probabilities at this time. ...Dean.. 10/30/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
