Coastal Bend "Wake Low" High Wind Event - April 24, 2015

High winds between 35 and 60 mph developed between 430 and 630 AM on April 24th, 2015 across portions of the Coastal Bend and adjacent waters. These winds were  produced by a meteorological phenomena called a "wake low". High winds from a wake low are normally caused  by rapid warming and drying on the back edge of a trailing stratiform region of rain  (usually associated with weakening thunderstorm complexes). This physical process can lead to falling pressure which in turn causes the winds to increase dramatically.  Winds several hundred feet above the surface reached speeds close to 90 mph at the  peak of this event! Pressure falls averaged between 5 and 7 millibars with this wake low event.
