Houston rolled into Juneteenth feeling more like a steam room than a holiday morning, with patchy fog and muggy air greeting early risers. Temperatures hovered around 81°F at area stations and never really cooled off overnight, which sets the stage for a brutally hot afternoon. Triple-digit heat-index readings are likely, with only scattered, short-lived storms offering brief relief. If you have to be outside, pace yourself and make plans to duck into air conditioning during the peak heat.
Afternoon Heat And Storm Chance
Inland highs should top out near 92°F, with a light south breeze of about 5 to 10 mph and a 20 to 30 percent chance of showers or thunderstorms this afternoon and again Friday night. Heat index values are expected to push into the 105 to 112°F range in many neighborhoods, creating dangerous conditions for outdoor workers and anyone without dependable air conditioning. A few storms could drop brief, heavy rain and trigger localized flooding if they train over the same spots, but widespread heavy totals are not anticipated.
According to the National Weather Service Houston/Galveston, a Heat Advisory is in effect through 10 PM CDT Saturday, so keep an eye on updated local forecasts.
Fog, Commute And Beach Risks
Patchy fog before 10 AM may knock visibility down to a few miles and slow the morning drive. Several area airports could deal with low clouds or brief delays early Friday as that fog hangs around. If you are beach bound, be aware that there is a high risk of dangerous rip currents through the weekend. Stick to guarded beaches and follow lifeguard instructions.
Any storms that bubble up today or tonight should stay scattered. A few could bring quick, heavy downpours and gusty winds, but widespread severe weather is not expected. Outdoor events may see spotty delays, so it is smart to have water, shade and a backup plan.
Beat The Heat Resources
For those who need a break from the heat, the city and community partners are operating cooling centers and assistance programs for vulnerable residents. You can call 3-1-1 or check local listings for locations and hours. Reliant and city partners have opened a network of sites across Houston to provide short-term, air-conditioned relief. For a quick rundown of participating locations and details, see 20 cooling centers open across the city.
Shift strenuous outdoor plans to the early morning or later evening, and give local radar a look before heading out this afternoon. Check back for updates if the advisory or storm chances change.
