HOUSTON – Summer has officially settled into Southeast Texas, and the weather is starting to look the same day after day. A strong area of high pressure is parked over the region, bringing plenty of sunshine, limited rain chances and afternoon temperatures climbing into the mid-90s. When you factor in Houston’s trademark humidity, it’ll feel even hotter, with heat index values topping 100 degrees each afternoon through the end of June.
Friday’s Forecast:
Expect another hot summer afternoon across Southeast Texas with plenty of sunshine. High temperatures will climb into the low to mid-90s, but the humidity will make it feel much hotter, with heat index values reaching 104 to 107 degrees.
A light southerly breeze will provide only limited relief, and while an isolated shower can’t be ruled out, most neighborhoods will stay dry through the evening.
The weather pattern changes very little through the next 7 days:
After what felt like two solid months of rain and a region that is no longer in a drought, a strengthening ridge of high pressure will take control this week, bringing hotter temperatures, fewer clouds, and no rain. The result will be a quieter forecast overall, but one that comes with increasing heat and humidity.
Afternoon highs will generally range from 92 to 96 degrees through much of the week, with overnight lows falling into the upper 70s and lower 80s.
While this won’t be an extreme heat wave by Houston standards, the lack of rainfall combined with several consecutive days of triple-digit heat indices will make for a prolonged stretch of summer heat. Most afternoons will feature heat index values between 104 and 107 degrees, and there may be isolated spots that briefly exceed those numbers.
Staying safe in the heat:
Wear loose-fitting, light-colored clothing if you do head outside, seek shade when possible, and check on elderly neighbors, young children, and pets. And never, under any circumstances, leave a person or animal alone in a closed car.
Plus, as our temperatures hit the 90s, it’s a good reminder of how hot it gets inside your car - reaching life-threatening temperatures quickly. According to Stanford researchers, on a 90-degree day a parked car’s interior can reach 109 in just 10 minutes and 133 in 60 minutes. Cracking the windows make no significant difference in the rate of temperature rise, it can still be life-threatening.
10 Day Forecast:
Looking ahead, the forecast remains remarkably consistent. High temperatures stay in the low-to-mid 90s through the beginning of July, while overnight lows remain in the upper 70s. Rain chances remain very limited for most locations through the weekend and into next week.
A few isolated showers may return around the middle of next week, but widespread rainfall is not expected at this time.
For now, Houston’s weather pattern is firmly locked into summer mode: hot afternoons, warm nights, plenty of humidity, and very few opportunities for cooling rain.
