Houston rolled out of bed to a soggy, low-visibility start Thursday, May 28, 2026, with fog and mist hanging over the city, temperatures near 68°F, and pockets of reduced visibility for early commuters. By afternoon, the script flips to a warm, mostly sunny setup that will send highs into the upper 80s.
Morning Fog, Slow Commutes
Dense fog remains possible before 9 a.m., especially in low-lying neighborhoods and along bayous, where visibility could drop to around one mile between about 6 and 9 a.m. Once the sun gets higher, the fog should thin out and skies turn mostly sunny, with a high near 88°F this afternoon. Rain chances stay low through Saturday, then start to climb Sunday into next week, according to the National Weather Service.
Afternoon Heat And Ozone Alert
By midmorning, the sun should be back in charge, and with only light north winds, the afternoon will feel sticky as temperatures rise to about 88°F to 90°F across much of the metro. The Texas Commission on Environmental Quality has issued an Ozone Action Day for the Houston–Galveston–Brazoria area for Thursday, May 28, 2026, and people with asthma, young children, and older adults are urged to limit long stretches of outdoor activity during the afternoon ozone peak. To help cut down on ozone formation, officials suggest sharing a ride, avoiding unnecessary idling, and postponing heavy yard work during the heat, per TCEQ.
Weekend Outlook
Warmer weather hangs on Friday through Sunday, with daytime highs around 90°F and only spotty, low-chance showers through Saturday. Several impulses are expected to undercut the ridge Sunday into next week, bringing higher chances for scattered afternoon showers and thunderstorms by Monday and Tuesday, so it is worth watching for any timing shifts that might collide with outdoor plans.
For the commute, use low beams in fog, ease off the gas on damp roads, and build in extra travel time this morning. Anyone sensitive to ozone should avoid prolonged outdoor activity this afternoon.
