81/60 here with higher dews to my south pushing northward temporarily. Interesting low topped line of storms near Chi town might provide some spin ups this afternoon as Alek mentioned in the svr thread. Could see some heavy rain issues. That cell se of Rockford seems like it has been sitting there torever.

nice drenching here on the gfs and NAM for the next 3-4 days. Is it normal for la nina springs to be this cool, wet and up and down with the temps here in the midwest? I know spring usually has temp flunctuations but it just seems more than usual this year.

Yes (in terms of the up and down temps). Last year was a strange La Nina because of how quickly it strengthened, it basically overwhelmed the other indices.
