Sunday's Forecast (Copyright KSAT-12 2026 - All Rights Reserved)
High severe storm chances in Oklahoma and north Texas today. Locally, there’s a slight chance of afternoon/evening storms, but a “cap” on the atmosphere should limit storm development. The “cap” acts as a weak lid on the atmosphere. If the “cap” breaks, then a storm producing large hail is likely. The chance of the “cap” breaking each afternoon is about 20%. It’s a bit of a wildcard an mostly a wait-and-see situation, so have an extra eye and ear to the sky.
EXTENDED FORECAST
A cold front is increasingly likely late next week with a downturn in temperatures by Friday combined with rain chances.
