Houston Weather: Warm, Muggy, and Afternoon Storms
Houstonians can expect a classic Gulf Coast day this Friday, May 17th, starting off warm and noticeably muggy. While we’ll enjoy a mostly cloudy morning, prepare for scattered showers and thunderstorms to develop during the afternoon and early evening hours.
Today’s Sticky Start and Rising Temperatures
As you step out this morning, you’re likely greeted by the familiar oppressive humidity that defines our late spring weather. Morning temperatures are hovering comfortably in the upper 70s, setting the stage for a warm day ahead. The humidity is already significant, ensuring that even moderate temperatures feel much warmer. Throughout the late morning and early afternoon, conditions will become partly sunny, allowing temperatures to climb steadily.
Expect afternoon highs to reach the upper 80s to even low 90s across the Greater Houston area. However, it’s crucial to remember that the combination of these temperatures with high humidity will make it feel significantly hotter. The heat index, or “feels like” temperature, is projected to be in the mid to upper 90s, especially during the peak afternoon hours before any storms arrive. Staying hydrated and seeking shade will be important, even if the thermometer doesn’t hit triple digits.
Afternoon and Evening Storm Chances
The primary weather story for Friday afternoon will be the potential for scattered showers and thunderstorms. These are not expected to be widespread but rather isolated to scattered in nature, primarily developing after 2 or 3 PM. The highest chances for seeing rain will be along and north of I-10, though isolated cells could pop up anywhere.
When these storms do develop, they have the potential to deliver a punch. The main threats associated with these afternoon cells include heavy downpours, which could lead to localized street flooding, especially in low-lying areas or where drainage is typically poor. Frequent cloud-to-ground lightning is also a significant concern. While organized severe weather, such as tornadoes or widespread damaging winds, is not anticipated, any strong thunderstorm can produce gusty winds and small hail. Rainfall totals could range from 1 to 2 inches in areas under persistent downpours, with isolated higher amounts possible, so keeping an eye on the radar will be beneficial.
Historical Context and Today’s Forecast
To put today’s temperatures in perspective, it’s helpful to look at our historical averages for May 17th. While we’re not breaking any records, we’re certainly above the norm for this time of year.

Looking Ahead: Your Weekend Forecast
For those planning outdoor activities, the weekend offers a mixed bag, though generally hotter and more humid than today. Saturday, May 18th, will see a slight decrease in rain chances, with only very isolated showers (around a 20% chance) possible, mainly during the afternoon. Expect partly cloudy skies, and it will remain hot and muggy, with high temperatures once again pushing close to 90 degrees. The heat index will continue to make it feel significantly warmer.
Sunday, May 19th, promises even more sunshine and heat. The forecast calls for mostly sunny skies, making it a prime day for pool activities or staying indoors with the AC. Temperatures will climb into the low 90s, and with continued high humidity, the “feels like” temperatures will be quite uncomfortable. Remember to prioritize sun protection and hydration if spending extended time outdoors.
