Oklahoma winter chill

Ugh. After a brief flirt with 72F (22 C), Oklahoma has plunged back into winter's icy grip. Biking, walking, jogging, heck even sleeping (with not-so-efficient [i.e., drafty] windows) are all made more difficult when the temp doesn't get much above freezing for over a week. The map at left is the morning wind chills during my jog. 4F isn't exactly balmy (18F temp + 15 mph wind = 4F wind chill). Ugh.
