Looking ahead, a pattern change could favor an uptick in severe weather potential over the central United States this weekend into early next week. A trough, or dip in the jet stream, will allow periodic spurts of cool air to spill out of the West while warm, moist air overspreads the Plains. Disturbances riding the jet stream will eject out of the Rockies, likely triggering thunderstorms, some severe, as they plow through humid air on the Plains.
