Same story here in Oklahoma. Earlier in the week it was up to the 70s during the day. Yesterday morning my ride to class was dry and about 55F. My ride to work in the afternoon was wet and about 32F. Today it's a little under 20F, and snowing. The water from the rain yesterday has frozen on the roads. Oh yeah, it has been windy since yesterday.

Today work was canceled and class was canceled. I still went for a ride around the neighborhood on my mountain bike though. I have a feeling class will be canceled again tomorrow.
