KATC StormTeam 3 Weather BLOG

After three days in a row with temperatures in the upper 90s we are somewhat optimistic on a few more clouds with a few showers and storms to help reduce the heat (a little) tomorrow through Thursday. A weak disturbance in the form of a surface trough and weak upper low off of the southeast coast of Louisiana will drift westward through Wednesday, allowing for deeper tropical moisture to move into at least parts of Acadiana, especially coastal and eastern parts through mid-week. Therefore we should see more clouds, earlier in the day limited the hot temperatures to the mid-90s, but as winds turn more SW’rly tomorrow afternoon our humidity will increase slightly thereby keeping heat indices close to the 105 degree mark during the afternoon. Rain chance tomorrow should increase to 20-30% and will be in the neighborhood of 40% for Wednesday and possibly Thursday. Highs will hopefully drop into the lower 90s for Wednesday and Thursday but unfortunately the ridge of high pressure will re-strengthen by the weekend, knocking the rain chances back down to the low side while highs creep back into the mid-90s. The tropics remain rather quiet other than the aforementioned weak trough in the Gulf of Mexico. At this point we are not expecting any development with this feature but if it persists for more than a day or two that could change.
