No severe thunderstorms are expected across the U.S. on Saturday. ...Synopsis... On Saturday, a broad upper trough will develop into Ontario, with a leading speed max moving from the northern Plains across the Great Lakes. Meanwhile, an upper high will be centered over the Great Basin, with relatively high midlevel heights extending into the Southeast. At the surface, a high pressure center will move from MI into the Northeast, with the surface ridge extending southwestward into the southern High Plains. Northeasterly surface winds will thus relegate the more robust moisture/dewpoints to the Gulf Coast states. Isolated thunderstorms may develop during the day over the Upper Midwest in association with the shortwave trough, as temperatures aloft cool. Moisture and instability will be minimal, but weak elevated instability should support at least isolated lightning flashes. Otherwise, scattered thunderstorms will affect much of the Gulf Coast and extending into the Carolinas as the air mass will become marginally unstable with heating. Weak shear will further preclude severe possibilities. ..Jewell.. 10/02/2026 $$
