Around 16:00PST Monday 23 Jan, the corner station weather station outside temp increased by about 13F. It occassionally drops back to the actual temps, but most of the time it has an offset. The wind speeds do not show this problem, so it looks like a possible sensor issue. Jim restarted tbe MSR base station which did not fix the issue.

The attached plot shows 3 days of minimum temps. The black plot is the CS, joined by a line to show the times it corrects itself.
