This is a MODIS Great Lakes satellite picture from Weds. (from NOAA Coastwatch). You can see plentiful cumulus clouds over the land areas (with the cool air aloft), but it’s mostly clear over Lake Michigan, where the cool water prevented the rising thermals. The wind is west along the shore in W. Michigan, N-NW in N. Indiana, NNE or NE in Chicago, but the lake breeze is not penetrating inland north of Milwaukee, where the cumulus clouds drift out over the lake and dissipate.

Typhoon Rammasun will hit far SE China and N. Vietnam today with very strong winds and heavy rain. This storm heads inland (does not recurve toward Alaska), so the ridge can build over the Midwest and Great Lakes and we can get warm early next week. The next tropical storm, Matmo, is a little weaker than Rammasun, and will head toward Taiwan. Overnight, roads flooded in the Bryan-College Station, TX area. Water rescues also occurring according to law enforcement. In 45 minutes, 0.78″ of rain accumulated near Mt. Morrison, CA, reports a NWS spotter – California needs all the rain they can get. Tennis ball-sized hail in Alberta, Canada.
