Wind chill temperatures this Wednesday morning are brutal with air temperatures well below zero and a brisk NW wind pushing values even further below zero over Iowa. The NWS has a Wind Chill Warning in effect primarily over northeastern Iowa covering locations like Cedar Rapids. The featured chart presents the frequency of having either a Wind Chill Advisory or Warning active at a given wind chill temperature since early 2006 for Cedar Rapids. The chart nicely delineates the thresholds at which these warning/advisory events are issued at. Values below -20 are mostly covered by the advisory with values below -30 and particularly below -35/-40 covered by the warning. One can hope this is the worst that this winter will have to offer, but there is still plenty more time to go!
