A few isolated thunderstorms are possible in the Texas Coastal Plain Wednesday morning. Scattered thunderstorms are possible early Thursday morning from the Ozarks to the Lower Ohio River Valley. ...Synopsis... A mid-level trough will amplify while traversing the north-central CONUS on Wednesday, prompting the rapid eastward progression of a 990 mb surface low along the U.S./Canada border. A trailing cold front will extend from the surface low to the Rockies, preceded by surface troughing and associated southerly moisture return from the western Gulf. Low-level warm-air advection should take place across eastern TX to the Ozarks through the day Wednesday, promoting marginal buoyancy amid some synoptic ascent attributed to surface troughing. By early Thursday morning, enough buoyancy should be in place for the development of isolated thunderstorms across the Sabine River Valley into the Ozarks. ..Squitieri.. 12/15/2025 $$
