Thunderstorms will be possible Tuesday night into Wednesday morning. Confidence is increasing in strong to severe storms capable of gusty winds and hail. An isolated tornado threat cannot be ruled out.
Windy conditions will exist outside of the thunderstorms. Gusts above 30 mph are likely.
Weaker low-level moisture return is expected farther north into parts of the Midwest and Ohio Valley in advance of a cold front. Despite weak buoyancy, favorable large-scale ascent and strong deep-layer flow could support a threat of locally damaging gusts with any sustained low-topped convection. There is some potential for a damaging wind threat to spread farther north than currently indicated, and some northward expansion of wind probabilities is possible depending on shorter-term observational and guidance trends.
