Location of the event listed here is a proxy to Brazos Santiago just north of the jetty, based on historical analogs of similar events with similar gusts in northerly flow along and behind significant cold fronts.

Wider weather episode

A late season cold front was accompanied by fast moving band of thunderstorms. Wind gusts associated with the storms reached 35 to near 45 knots from the north as they swept through; in some cases, the high gusts lasted for nearly two hours. Similar gusts continued after the storms passed, associated with the pressure gradient from high pressure building through south Texas from the north.
