5-Day Outlook

The heat continues, but rain chances increase to low-moderate (20-40) across deep South Texas with increased Gulf moisture. Isolated showers and thunderstorms off the Gulf will move inland through today. Widespread rainfall amounts of 0.25 inches or less are expected, but locally heavier showers could bring higher totals which can lead to ponding. Storms are not expected to be severe.

An unsettled weather pattern along with a plume of Gulf moisture will increase rain chances throughout Deep South Texas today and tomorrow. Rain amounts are expected to be low (less then 0.25 inches for most areas) but heavier showers and thunderstorms can cause locally higher totals along with some water ponding. No severe weather or flash flooding is expected.

Wildfires are caused by a spark (usually man-made) in the presence of fuel (dry vegetation) and oxygen. Strong winds, high temperatures, low humidity and drought conditions can further impact the fire’s spread.

Favorable weather and surf conditions are in store for local beaches today.

Hot temperatures and daily chances of showers and thunderstorms will persist into next week. Elevated rain chances across deep South TX last through Friday, before returning to an afternoon sea breeze pattern near the coast this weekend.
