AUSTIN / UNIVERSITY OF TEXAS WEATHER
SEVEN DAY WEATHER HEADLINES…
(1) A general area of upper level high pressure, acting like a “lid” on our atmosphere, has, as advertised, has weakened and shifted more north of the area. This allowed a weak westward moving disturbance to move into far southeast Texas and into the Texas coastal plains today with scattered rain showers and thunderstorms expected later today and tomorrow over the IH35 corridor and Austin metro area.
(2) As the atmosphere becomes a little more stable Thursday, rain chances will drop from the forecast.
(3) Our next west northwestward moving tropical wave is forecast to move through the Gulf of Mexico this week arriving in the northwestern Gulf of Mexico by late Thursday through Friday and then moving ashore into Texas Friday night into the weekend with better rain chances locally with some of that rainfall potentially heavy. With the now increased NWS/National Hurricane Center chance of tropical cyclone development, all interests along and onshore of the Texas coast should closely monitor the latest information from the National Weather Service and the National Hurricane Center over the next few days.
