Summary: Severe, or high rainfall-producing storm clusters, will be a possible tonight into Friday morning, generally along and northwest of a Brenham to Crockett line.
A mid to upper level storm system will approach from the west through the day with its associated slow-moving cold front reaching central Texas tonight. This front will be entering a highly moist and warm environment and, due to the overall slow movement of the front itself, developing clusters of rain and embedded storms will increase the extreme northern forecast area flood threat. The higher rainfall is forecast to be west/northwest of southeastern Texas tonight through Friday morning.
A slow moving band of thunderstorms may move into or develop over points northwest of a Brenham to Crockett line that could produce a flash flood threat Thursday night into Friday morning.
Light rain, or showers with isolated thunderstorms, will linger behind this near-stationary front Friday afternoon through Saturday, but any early Friday severe thunderstorm threat will significantly diminish. At this time, Friday night through late Saturday’s rain will not produce a flash flood threat.
A secondary, stronger cold frontal passage Saturday afternoon will strengthen offshore winds in its wake. Saturday afternoon through mid Sunday coastal sustained northeast winds will range between 20 to 30 mph with higher gusts. Marine small craft advisories will likely be required, along with a possible overnight coastal wind advisory.
