The featured plot was taken from the RWIS time series plotter for the Ames site. You may want to click the image to get a better view. You can see how the pavement temperatures warm more than the air temperatures during the day. The implication is that the increasing solar angle is becoming more direct on the pavement surface and thus able to more efficiently warm it. So the next time winter precipitation falls, it won't take much sunshine to quickly melt the mess away.
