First things first.. I hope you’re having a good Labor Day…

We are dealing with two different weather features on this Labor Day. As far as this
statement is concerned, I will deal with them separately..

… Tropical Cyclone Gordon …
See the graphics below courtesy of the NWS/National Hurricane Center. Model guidance
is very consistent on bringing the tropical cyclone.. as a minimal hurricane.. onshore in the middle Gulf Coast region of Southeastern Louisiana.. Mississippi and Alabama coasts in the nighttime and overnight hours tomorrow night into the predawn hours Wednesday morning. After landfall, the system will move northwestward and weaken with the most direct effects being well to the east and northeast of our area. Unless things change, this will be my last reference to Gordon.

… Heavier Rainfall Potential for South Central Texas Over the Next Seven Days …
Not the direct effect of tropical cyclone Gordon, we have had major changes occurring over the last couple of  days in our atmosphere over south central Texas. In addition to the weakening/collapse of the upper level high pressure area which as been holding stubbornly overhead through the summer – I often refer to as a “lid” on the atmosphere – we’ve seen a big increase in Gulf of Mexico moisture moving northwestward into our area. You combine all of this with an increasingly unstable atmosphere and a weak atmospheric low over north and west Texas, we have higher rain chances than we’ve seen lately; this type of weather pattern is expected to persist through much of the next seven day forecast period. With the threat of periods of heavier rain will come the danger of frequent cloud-to-ground lightning as well as some strong, gusty and variable winds to 40mph. Even with the ongoing drought over the area, some flooding of low water crossings and urban/small stream areas is possible. It is possible that a few NWS issued Flash Flood Warnings will be
released where heaviest amounts fall quickly.

The latest NWS/Weather Prediction Center rainfall guidance suggests that our area of south central Texas could see, on average, about 2 to 4 inches of rain through next Sunday with isolated higher amounts certainly possible.

In closing, I will continue to keep you informed on this potential heavier rainfall event for south central Texas.
