Houston is starting Saturday clear and around 73 degrees, but the comfortable morning will give way to a hot afternoon near 92. Skies will turn partly sunny as temperatures climb, with light northeast winds offering only modest relief.
The National Weather Service Houston/Galveston forecast calls for a mostly dry weekend, with Sunday and Monday reaching about 93 degrees. Most Houston neighborhoods should stay rain-free through Monday, though isolated showers or thunderstorms could develop near the coast and southern parts of the region.
Ozone Alert Covers Saturday
An Ozone Action Day is in effect for the Houston, Galveston and Brazoria areas through 7 p.m. Saturday, as sunny and warm conditions favor higher ozone pollution, according to the National Weather Service. Residents can help by combining errands, avoiding drive-through lines when possible, carpooling and limiting strenuous outdoor activity if they are sensitive to air pollution.
There are no watches or warnings for the Houston area. Still, Saturday afternoon will be a rough time for long stretches outside, especially as temperatures reach the upper 80s and low 90s while the sun breaks through the clouds.
Rain Chances Rise After Tuesday
The forecast begins to shift Tuesday, when a 30% chance of showers and thunderstorms arrives after 1 p.m. Rain chances rise to 60% Wednesday and 50% Thursday, with showers and thunderstorms likely at times and highs in the upper 80s Wednesday and 86 Thursday.
Friday remains unsettled, with more showers and thunderstorms likely and a high near 87. Forecasters are watching for a wetter pattern from Wednesday into the end of the week, although the exact timing, coverage and rainfall totals remain uncertain, as detailed in Hoodline's previous forecast.
For weekend plans, the best window for outdoor errands is Saturday morning or earlier Sunday, before the heat builds. By midweek, umbrellas and flexible schedules may become more useful than sunscreen alone.
