.DISCUSSION...
Issued at 1006 PM CDT Tue Sep 16 2025
Unsettled weather will continue to be the rule throughout the
period, with an active weather pattern in place. This will be due
to generally robust precipitable water values interacting with
daytime heating, the east-to-west migration of the daytime
seabreeze boundary, and a series of disturbances that will "ridge
ride" 500 mb high pressure centered more or less over northwest
Mexico.
Temperature-wise, the daily threat for showers and thunderstorms,
along with the associated cloud cover, will have a dampening
effect, with values more near normal for this time of year.
Finally, with continued slightly elevated seas, a Moderate Risk of
rip currents is likely for the beaches along the Lower Texas
Coast.
