Yesterday’s thunderstorm activity probably came as a bit of a surprise to many of us, not so much because they happened but because of how potent they were. We saw a few reports of hail and wind damage around the region. And some incredible sky pictures.

Severe weather damage at M and M Air Service in Winnie. Witnesses say at least two airplanes inside the hangar suffered severe damage. Awaiting @NWS to confirm if tornado. @NWSLakeCharles @NWSHouston #12NewsNow pic.twitter.com/zASLhdSGuM

Our Friday forecast suggested the most activity would be east of US-59 on Saturday, and it was, but I’d be lying if I told you I was expecting the potency that it came with. So why did it happen?
A confluence of factors led to a busy Saturday evening. Storms early in the day in western Louisiana and eastern Texas likely produced some boundaries in the atmosphere, and with winds directing weather in the less common northeast to southwest direction, they ended up moving our way. We probably saw cold air aloft, necessary to help regenerate storms as they moved across southeast Texas. We had sea breeze interaction with some of those boundaries also. There was decent jet stream and upper level support in the northeast flow that helped add extra support. Then, it also hit 94° at IAH, so you had plenty of instability. All these factors came together just right, and we ended up exceeding most people’s expectations, including my own.
So that begs the question: Will we do it again today?
