Houston Weather: Sunny Skies, Poor Air Quality, High Pollen, and Approaching Rain

Tuesday's Weather Conditions

• ☀️ Houston is experiencing sunny skies and calm conditions on Tuesday.
• ⚠️ A key concern is poor air quality due to ground-level ozone, exacerbated by sunny conditions and regular pollutants.
• 😷 Individuals with asthma, respiratory issues, or heart/lung conditions are advised to limit outdoor activity, especially strenuous exercise.
• 🤧 Sky-high pollen levels, particularly from trees (over 9,000), along with moderate ash, hackberry, grasses, and mold, are also contributing factors.

Temperature and Humidity

• 🌡️ High temperatures are expected to reach near 90 degrees, close to record highs but not breaking them.
• 💧 Significant moisture is present, with a strong Gulf breeze contributing to humid and sticky conditions.

Mid-Week and Weekend Outlook

• ☁️ Wednesday will see an increase in cloud cover, leading to slightly cooler temperatures.
• 🌧️ Shower chances begin on Thursday with a 40% probability, primarily affecting areas southwest of Houston like Corpus Christi and Brownsville.
• ⚾ For Opening Day at the Astros game on Thursday, expect scattered showers on and off throughout the afternoon, with cooler temperatures in the low 70s.
• 🌊 Friday brings a significant increase in rain chances to 80% as a low-pressure system moves directly over Houston, bringing heavier downpours.
• ⚠️ Flood risks are present on both Thursday and Friday, with a marginal risk for street flooding in northern areas and a level two threat (majority of Harris County) for localized flooding closer to downtown and along I-10.
• 🌫️ Overnight and early morning on Thursday, there's a potential for dense fog streaming in from the Gulf, which could reduce visibility to half a mile to a mile, particularly impacting travel to airports.
• ☀️ By Monday, rain chances drop off, and sunshine is expected to return.
