The Great Lakes have been unusually ice-free this winter. In this image from Feb. 13, ice cover on the lake was 7 percent – the lowest ice cover measured on this date of any year since 1973 when satellite-based record keeping began.

We've been having spring-like temps in North Carolina since the big arctic freeze hit us at Christmas. Overnight temps have mainly been in the 40s and 50s, when they would normally be in the 20s and lower 30s, with at least a few nights in the teens. Yesterday I saw a cloud of gnats flying in the yard. We don't usually see them until late May.
