Houston woke Thursday, September 10, to clear skies, calm winds and temperatures around 79 degrees, but the quiet start is expected to give way to another round of scattered showers and thunderstorms. The city could reach near 90 before clouds and storms pull readings back into the upper 80s during the afternoon.
Storms Build After The Late-Morning Warmup
Rain chances will increase from late morning into the afternoon, with a 50% chance of showers and thunderstorms overall. Most neighborhoods will not see a washout, but brief heavy downpours are possible, especially across southern Houston and areas closer to the coast.
Southeast winds should stay light at 0 to 5 mph, and rainfall totals will generally range from a tenth to a quarter of an inch. The steamiest stretch arrives before storms develop, with humidity making the afternoon feel hotter than the thermometer suggests.
A Few Stronger Cells Could Pack A Punch
Most storms are expected to remain scattered, though a few stronger cells could bring gusty winds, pea-size hail and very heavy rain for a short time. The National Weather Service Houston/Galveston says those stronger storms are possible but not expected to be the rule, and no watches, warnings or advisories are in effect.
Sticky Storm Pattern Hangs On Through Next Week
Friday will look much the same, with a high near 91, heat index values as high as 101 and a 40% chance of afternoon showers and thunderstorms. Saturday and Sunday bring highs near 90 to 91 with storm chances around 50%, while Monday and Tuesday stay near 91 with afternoon rain chances of 30% to 40%.
The extended outlook is a substantive update to the earlier Houston forecast, with scattered storm chances now continuing into Wednesday. Outdoor plans can still work, but keeping a backup option handy from late morning through afternoon would be wise.
