A small storm complex make its way over Iowa on Monday dumping heavy rain and producing a fair amount of wind damage in its wake. This wind damage was from a strong "wake low" structure that can be seem by observing rapid pressure falls behind an area of precipitation. The featured chart is from the Colo KCCI SchoolNet station showing a rapid pressure drop along with increasing winds to over 65 mph. If you look carefully, you can see the absolute peak in wind speed (68 mph) occurred as the pressure reached its lowest value.
