Strong to severe thunderstorms are possible across portions of the Midwest late Monday afternoon into Monday night. ...Eastern KS to OH... A deepening upper trough will develop southward into the Upper Midwest on Monday/Monday night. Stronger height falls will remain confined to the Upper Midwest/Great Lakes vicinity, with more modest height falls into the Mid-MS Valley near/after 00z. At the surface, low pressure is forecast to move across Ontario and Quebec, while a trailing cold front develops southward across the Upper MS Valley during the day, and becomes oriented from southern Lower MI to eastern KS by early Tuesday. Gulf moisture return will remain limited, with generally 50s to near 60 F dewpoints expected in a narrow corridor ahead of the cold front. Cool temperatures aloft will support steep lapse rates across the region and MLCAPE around 1000-1500 J/kg is forecast during the afternoon into the nighttime hours from KS into portions of the Mid-MS Valley and eastward into IN/OH/extreme southern Lower MI. Capping and weak forcing for ascent may limit thunderstorm development across the warm sector through peak heating. However, as a southwesterly low-level jet increases around/after 00z, modest height falls overspread the region, and the surface cold front develops southward toward the corridor of modest boundary layer moisture, isolated to scattered thunderstorms may initiate. Effective shear around 35+ kt will aid in organized storm structures, and isolated large hail and locally strong gusts are possible. ..Leitman.. 05/02/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
