Latest 18Z ETA (4/4 run) looks interesting for the Great Lakes on Thursday afternoon. Good instability combined with good low level helicities, may create a good severe weather threat. ETA indicates convective initiation around 18-21Z THU across this area, so it should be during prime heating...Overall, looks like a decent threat for severe weather, with the potential for some supercells...Unlike the last couple "events" across the Great Lakes, maybe this one will actually happen...
