FORECAST

The last day of April will give us a slight storm chance. We’re also watching storm chances on Friday night. Here’s an update on what may unfold.

ISOLATED SEVERE STORMS LATER TODAY

We’ll start the day off mostly cloudy, with sunshine by midday. This will give us some warm temperatures (near 90). It’ll also destabilize the atmosphere. So, as a low pressure system passes to our north, a few storms may flare up between 3pm and 10pm. While we don’t expect widespread stormy weather, should a storm pop up, severe weather is likely. Otherwise, it’ll by partly cloudy, warm, and humid.

RAIN CHANCES INCREASE FRIDAY EVENING

Thursday brings another round of isolated storms (severe weather remains possible). But, it’s on Friday that rain chances really ramp up. A weak front will sink south towards South Texas. While the exact timing remains in question, the best rain chances are trending later on Friday. We’ll continue to see a chance for showers and storms through Saturday morning. Heavy rain, at least in spots, could become an issue.
