Severe thunderstorms are not expected on Tuesday. ...Synopsis... A series of upper troughs will migrate across the north-central U.S. on Tuesday while upper ridging amplifies over the East. Southerly low-level flow will maintain modest boundary layer moisture (mainly 50s F dewpoints) from OK/KS into the Upper Midwest/Great Lakes, with 60s F dewpoints possible further south across TX. A surface front initially over KS to central IA will lift northward through the period in response to increasing low-level warm advection ahead of a shortwave trough traversing the northern Plains. Isolated thunderstorms are possible within the broader warm advection regime across parts of the Plains from South TX into the Mid-MO Valley. Modest instability and generally weak vertical shear will preclude severe potential. ..Leitman.. 10/25/2026 $$
