A mid/upper level storm system will approach from the west tomorrow, and coupled
with a slow moving cold front and deep moisture, will set the stage for shower and
thunderstorm development. Most of the storms will be west/northwest of southeast
Texas tonight through Thursday morning.
On Thursday afternoon, showers and thunderstorms will increase in coverage especially
across northwest areas. This is also the time that severe thunderstorms will become a
possibility, generally along and northwest of a Brenham to Crockett line. The severe
thunderstorm threat will persist through the evening hours. See the attached graphic.
A slow moving band of thunderstorms is expected to move into or develop over northwest
areas of southeast Texas which could produce a flash flood threat Thursday night into Friday morning. We will be monitoring the Brenham to Crockett and westward area for a
Flash Flood Watch.
The chance of showers and thunderstorms will remain behind the front Friday afternoon and Saturday, but the severe thunderstorm threat is expected to diminish. Locally heavy rainfall
is a possibility on Friday night into Saturday morning generally across the northern half of
southeast Texas. At this time the rainfall Friday night does not look to produce a flash
flood threat.
