Houston’s Sunday Forecast: Heat and Scattered Storms
Houstonians can expect another typical summer day this Sunday, July 28, 2024, characterized by pervasive heat and high humidity. While the sun will dominate for much of the day, there’s an increasing chance of scattered afternoon thunderstorms, particularly as we move into the late hours. Staying informed and prepared for rapidly changing conditions will be key to navigating the day comfortably and safely.
Morning Conditions: Warm and Humid Start
As Sunday begins, residents will wake up to warm and notably humid conditions. Overnight lows across the region have generally settled into the upper 70s, setting the stage for a muggy start to the day. Expect partly cloudy skies as the sun begins to rise, with southerly winds already ushering in Gulf moisture. This early humidity will be a persistent theme, contributing significantly to how warm the day will ultimately feel, even before peak afternoon temperatures arrive. Commuters and early risers should anticipate these already heavy air conditions.
Afternoon Peak: Blazing Heat and Storm Potential
The core of Sunday’s weather will be found in the afternoon, where temperatures are forecast to climb steadily. Highs are expected to reach the mid-90s across most of the Houston metro area, with some inland communities potentially touching 96°F. However, the true discomfort will come from the heat index, or “feels like” temperature, which is projected to soar well into the 105°F to 108°F range due to the oppressive humidity. This level of heat poses a significant health risk, making outdoor activities strenuous and potentially dangerous if proper precautions are not taken.
Adding to the afternoon’s complexity is the potential for scattered pop-up thunderstorms. While not everyone will see rain, there’s a 30-40% chance of showers and thunderstorms developing, especially west and northwest of downtown Houston. These storms, if they materialize, could bring brief but heavy downpours, lightning, and gusty winds. Their development is largely driven by the daily heating and ample moisture, creating an unstable atmosphere. Storm activity is most likely between 2 PM and 7 PM, with intensity varying greatly from one neighborhood to another.
Evening Outlook: Lingering Humidity and Clearing Skies
As Sunday transitions into the evening hours, the overall weather pattern is expected to gradually settle down. Any lingering afternoon thunderstorms should begin to dissipate shortly after sunset, though localized heavy rain might continue in areas where storms were more persistent. Temperatures will slowly recede from their daytime highs, dropping into the upper 80s and then eventually into the low 80s overnight. Despite the temperature drop, the humidity will remain very high, ensuring another warm and muggy night for Houstonians. This continued moisture sets the stage for similar weather patterns in the early part of the new week.

What to Watch Next Week
Looking ahead, the early part of the upcoming week is forecast to maintain similar summer conditions. Expect persistent high temperatures in the mid-90s, with heat index values continuing to hover around the 105°F mark. The daily routine of high humidity and a slight chance for scattered afternoon or evening thunderstorms will likely continue through Monday and Tuesday. There are no significant changes in the weather pattern anticipated, meaning Houston will remain under the influence of its typical hot and muggy July climate. Residents should continue to monitor local forecasts for any specific heat advisories or severe weather alerts.
Frequently Asked Questions
- Will it rain all day in Houston on Sunday?
No, while there’s a chance of scattered thunderstorms, they are most likely in the afternoon and will not impact all areas nor last all day. Expect plenty of sunshine otherwise. - How hot will it actually feel on Sunday?
The actual air temperature will be in the mid-90s, but the high humidity will make it feel much hotter, with “feels like” temperatures reaching between 105°F and 108°F during the peak afternoon hours. - Is it safe to be outside for extended periods?
Due to the extreme heat index, it is advisable to limit outdoor activities during the hottest parts of the day (noon to 6 PM). If you must be outside, take frequent breaks in the shade or air conditioning and drink plenty of water. - What should I do if a storm develops in my area?
Seek immediate shelter indoors if you hear thunder or see lightning. Pop-up storms can bring heavy rain, strong winds, and dangerous lightning very quickly. - Are there any heat advisories issued?
Given the forecast “feels like” temperatures consistently above 105°F, it’s highly probable that a Heat Advisory will be in effect for parts of the Houston area. Always check the latest NWS alerts for official guidance.
Remember to stay well-hydrated, take frequent breaks in air-conditioned environments, and monitor local weather updates throughout Sunday to navigate Houston’s intense summer conditions safely.
