Meanwhile, a weak southern-stream perturbation - apparent in moisture-channel imagery over central TX and the Edwards Plateau - will move eastward across east TX and LA/MS through 00Z, while slowly weakening. Related 500-mb height falls should extend about as far south as TN today, before the trough ejects across QC and the Northeast overnight. This trough is forecast to pivot across the upper Great Lakes and lower/mid-Ohio Valley today, while assuming less-positive tilt. Damaging wind gusts will be the primary hazard, with a tornado or two possible.Ī broadly cyclonic pattern has developed in mid/upper levels over most of the CONUS, with the dominant feature being a strong shortwave trough initially located from Lake Superior across southern WI to northeastern KS. Scattered strong to severe storms are expected today from east Texas to portions of the Tennessee Valley. Here is the latest text from the Storm Prediction Center: Damaging winds up to 60 mph will be the main threat, but there is also a small, non-zero, threat of a brief spin-up tornado. Severe threat will continue across the area from northwest to southeast from now until at least 1 pm today. A Marginal Risk for severe storms continue for Scottsboro, Rainsville, Gadsden, Anniston, Talladega, Clanton, Alexander City, Auburn, Montgomery, and Troy. The Slight Risk includes the cities of Russellville, Athens, Decatur, Huntsville, Hartselle, Cullman, Guntersville, Hamilton, Birmingham, Hoover, Tuscaloosa, Demopolis, and Selma. The Storm Prediction Center has upgraded the severe risk across much of North/Central Alabama to a Slight Risk for severe storms.
