Although yesterday's high temperature of 78 degrees F (10 degrees above average) before 12:30 pm may not have seemed like a predictor of a storm coming, there were quite a few hints yesterday that predicted what today's weather would be like.

All day yesterday, the weather was fair and sunny. My Irish skin even got a good burn going after being outside for an hour. It was a steady upward climb through 12:30 pm for the temperatures yesterday. The coldest point in the day came at 4:45 am when the temperature was 45 degrees F (2 degrees above average).

A nice breeze accompanied the day to cool off the skin of the unsuspecting pasty people of Eau Claire who did not realize they were being burned by the sun's rays. The wind was blowing at about 11 mph from the SW for most of the day. One of the big indicators that we would not be seeing the same kind of weather today as we did yesterday was the shifts in wind direction throughout yesterday. Throughout the day, ESE winds shifted to WSW winds, back to ESE, to SW, to ENE, to predominantly W, then NNE through sunset and then back to W. The drastic nature of these shifts clued me in to the coming cold front.
