The intense dome of hot air over Texas has shifted westward, allowing high temperatures to drop a few degrees. This also allows the sea breeze to become more active with afternoon showers forming along the coast and drifting westward.

Sea breeze showers will become more numerous starting today. These might produce some brief downpours and occasional thunder but rain chances remain near 20% area wide. Whatever showers that do develop dissipate quickly with sunset.

Overall though, the summer pattern continues with hot, breezy and humid afternoons. Highs will be in the middle 90s through the weekend. Overnight conditions will generally be clear with low cloud cover in the pre-dawn hours and early morning. Lows remain in the middle 70s.

In the tropics, a large area of disorganized showers and thunderstorms over the western Caribbean Sea is associated with a trough of low pressure. This area of disturbed weather is expected to move westward to northwestward over Central America and the Yucatan Peninsula during the next couple of days. Little, if any, development is expected during that time.

Beware of any prediction based on a single forecast model. Social media is especially prone to dramatic forecasts of this type. Share only trusted sources of weather information like the National Hurricane Center, taking appropriate precautions when reliable predictions are issued.

Longer range forecast models indicate a tropical wave may form in the southwestern Gulf of Mexico by Sunday. It is still too soon to know exactly how this potential system may develop. Right now it looks like deep tropical moisture may move into Texas and northern Mexico bringing an extended chance of rain which may linger well into the next week.
