Windy wake low

Posted: 10 Jul 2009 06:05 AM

Sometimes the winds experienced on the backside of a storm complex can be stronger than what occurs with the precipitation. The featured chart is a 1 minute interval timeseries from the United Community SchoolNet8 station east of Boone Iowa. The rapid pressure drop shown was associated with the backside of a thunderstorm complex to the south comprising a surface "wake low" structure. Wind speeds increased until when the pressure stopped dropping.

Good = 27
Bad = 10
