Widespread severe thunderstorm potential appears limited through the remainder of March amid persistent upper-level ridging across the central and western CONUS. Isolated to scattered thunderstorms may materialize across portions of the TN Valley and Mid-Atlantic on D4/Friday as a strong cold front pushes east/southeast towards the East Coast and northern Gulf. However, limited mid-level lapse rates across the southeastern U.S. will likely modulate the potential for severe thunderstorms. Surface high pressure building across the eastern Plains and OH Valley in the wake of the cold front - combined with the re-amplification of the upper ridge over the western U.S. - will further limit severe thunderstorm potential for much of the weekend and very early next week. A gradual eastward translation of the surface high will likely promote the initial stages of moisture into the central U.S. around the D7/Mon or D8/Tues time frame. Most deterministic solutions and ensemble systems hint at an upper-level regime shift as the upper ridge shifts east and southwesterly flow becomes more prominent over the Southwest. This may support some increase in severe weather potential by the middle of next week, and possibly as early D8/Tuesday, but predictability at this range appears very limited. ..Moore.. 03/24/2026 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
