KATC StormTeam 3 Weather BLOG

As expected the weak disturbance just off the Louisiana Coast has hurled some tropical moisture into Acadiana bringing clouds with scattered thunderstorms across the area. Tomorrow should bring better coverage of the storms with chances of getting wet increasing to at least 50%. We do need the rain and also the break from the heat should be nice with Wednesday’s projected highs near 90. The disturbance in the Gulf looks small but impressive on the visible satellite imagery with some mid-level cyclonic turning showing. Buoy, ship and platform data have not shown organized winds nor have pressures dropped; however, this feature is under a tropical ridge aloft. Therefore, some weak development could be possible as long as this feature remains over water. This disturbance is expected to drift inland across the area late tomorrow and then weaken and get sheared off to the northeast as a very weak frontal trough drops down from the north later this week. The bottom line should translate to a good chance of showers and storms tomorrow with a better than average chance of showers and a few storms through the end of the week. It will get a little hotter this weekend with highs pushing back into the low-mid 90s but there will still be the chance of a few afternoon storms. The longer range models are interestingly enough indicating another disturbance that may spin off from the aforementioned frontal trough over the Gulf States this weekend and then drift westward across the area next week so we could see enhanced rain chances again by Sunday or early next week. Elsewhere in the tropics a couple good looking waves have emerged off the African Coast.
