Unusually warm humid air will build up ahead of a Canadian cold front arriving in the Coastal Bend late Wednesday night. It will be windy ahead of the front then a line of scattered thundershowers along and just ahead of the front moving from north to south across mainly the eastern half of the area between 10 pm and 4 am. Much cooler and drier air will push in behind the front with some fine Fall weather to follow for Thursday through Saturday.
Wednesday will be on the windy side humid and rather warm with variable sunshine and a high of 86.
Wednesday night will be warm breezy and stuffy for trick or treaters the scattered showers and thundershowers developing from the north mainly after midnight and a low of 61.
Thursday expect clearing skies with decreasing winds less humid and much cooler with a high of only 72.
Temperatures sink all the way to near 50 degrees under clear skies Thursday night and Friday looks fabulous.
