Sporadic damaging winds will be the most likely severe hazard throughout this corridor, with the greatest likelihood across the Lower Great Lakes. Synopsis A midlevel trough is forecast to move from the northern Plains into Ontario on Saturday As this happens, a surface low should lift northward from northern Illinois/southern Wisconsin into Ontario as well and a surface cold front will accelerate eastward across the Great Lakes and be approaching the East Coast by Sunday morning. To the southwest, the cold front will not progress as quickly, but should advance south and east through the day. Southeast Lower Michigan, Ohio, Western Pennsylvania, and western New York As the surface low lifts northward into Canada on Saturday, showers and thunderstorms are expected to be ongoing along and ahead of the trailing composite cold front/convective outflow. At the same time, a surface warm front will lift slowly northward across Lower Michigan. To the south of this front, and ahead of the cold front/outflow, a moist airmass, characterized by low-to-mid 60Fs dewpoints should be in place. Despite the strongest large-scale ascent being displaced to the north and west of the warm sector and weak midlevel lapse rates atop the warm sector, pockets of insolation should be sufficient to destabilize the environment enough to support some convective redevelopment along and ahead of the composite outflow/cold front. Modest instability will combine with seasonably strong low-level wind fields to support a convective wind threat and an isolated tornado threat along the leading edge of any sustained linear segments. Tennessee Valley southwest to eastern Texas Widespread thunderstorms are expected to be ongoing across the western portions of this area at the start of the forecast period. These thunderstorms will likely be driven by convergence along the east/southeast moving composite cold front/convective outflow boundary, with the exact western edge of any severe threat demarcated by where this boundary is located at the start of the forecast period. Seasonably high precipitable water values should support some threat for strong wind gusts in the most intense thunderstorm cores. These thunderstorms are expected to continue through the day, despite weakening large-scale ascent and vertical wind shear as the midlevel low pulls farther away. Given the seasonably high precipitable water values, modest insolation should support MUCAPE values between 500 and 1000 J/kg (perhaps as high as 1500 J/kg) across portions of Texas, Louisiana, and Mississippi. This may support a re-intensification of ongoing convection which would be capable of sporadic damaging downbursts
