THROUGH TUESDAY
Humidity will return Monday, and temperatures will be in the mid-80s. Tuesday will be downright hot and humid. Expect a high near 90° with a peak heat index closer to 100°.
WEDNESDAY
An upper-level low and a cool front will approach Texas. This will spark off a couple of storms, especially Wednesday afternoon. If a storm can get going, it would be strong or severe. We’ll continue to monitor.
THURSDAY & FRIDAY
Spotty rain is possible (20%-30%). The bigger story will be that Thursday will be much cooler. Highs in the low-70s thanks to a north wind and some cloud cover.
MOTHER’S DAY WEEKEND
There’s still a question as our storm chances. Right now, we have spotty (30%) storms in the forecast for both Saturday and Sunday. Otherwise, it will be warm and humid. We’ll continue to keep you updated as we adjust the forecast!
