Houston wakes up in thick, muggy air this morning, with temperatures hovering around 73°F at KHOU and pockets of patchy fog near bayous and low-lying neighborhoods. Expect that fog between about 7 and 8 a.m. to thin quickly, then sunshine will send the afternoon high to around 91°F with light southwest winds. An Ozone Action Day is in effect for the Houston–Galveston–Brazoria area, so anyone with breathing issues should plan on dialing back intense outdoor activity this afternoon.
Foggy Morning, Sunny Afternoon
The fog will be most noticeable early in the commute and should burn off by mid-morning, leaving mostly sunny skies and a hot, sticky afternoon. Southwest winds will stay light, which keeps the humidity hanging around and pushes heat indices into the 90s, with a few spots flirting with triple digits. These forecast details come from the NWS Houston/Galveston.
Air Quality Alert
The Texas Commission on Environmental Quality has issued an Ozone Action Day for today, with afternoon ozone levels expected to reach the unhealthy-for-sensitive-groups range. TCEQ recommends cutting down on short vehicle trips, avoiding idling and postponing gas-powered yard work to help keep ozone levels in check. More information is available from TCEQ.

Weekend And Next Week
Saturday stays similarly warm with a high near 92°F and overnight lows in the mid-70s, and Sunday looks to top out around 90°F. Rain chances remain low through the weekend but pick up early next week, with scattered showers and thunderstorms becoming more likely by Monday and Tuesday. If you have outdoor plans later in the week, keep an eye on the timing and consider an indoor backup just in case.
On the roads this morning, use low beams in the fog and budget a little extra travel time. If you are sensitive to ozone, move strenuous activities to the cooler morning or evening hours and drink plenty of water to handle the afternoon heat.
