From KIND
A closed upper
low and associated surface low are progged to track through the
northern Great Lakes Region on Tuesday. This will be a quick moving
system though with any shower/thunderstorm chances out of the area
by Tuesday night. However, thunderstorms will be a threat on Tuesday
afternoon/evening as the environment destabilizes in the warm sector
of the surface low. Southwest surface flow will push daytime highs
back into the mid to upper 80s for a day with dew points in the 60s.
With the moderate instability and forcing, would not rule out
isolated strong thunderstorms at times.
