Austin woke up Thursday, May 21, 2026, under muggy, mostly cloudy skies, with temperatures hovering near 72°F and a dew point around 69°F. In other words, the kind of sticky air that makes it feel like you are walking through a light veil of warm mist. Visibility is around nine miles, and winds are light from the east-southeast. Scattered morning showers are possible, but plenty of neighborhoods will likely stay dry.
What To Expect Today (Thursday, May 21, 2026)
Today looks mostly cloudy, with a high near 82°F and about a 50% chance of showers and thunderstorms, especially from late morning into early afternoon, according to NWS Austin/San Antonio. Rainfall amounts could land in the quarter- to half-inch range where storms do develop. Coverage should be isolated and spotty, so whether you get drenched or barely see a sprinkle will depend a lot on where you are. Any stronger storm cell could bring brief heavy downpours and localized street flooding. Overnight lows should hold in the upper 60s.
Commute And Local Plans
For the morning and midday commute, plan on the possibility of wet roads and brief visibility reductions. Give yourself some extra time, slow down around standing water, and do not try to plow through deeper puddles. Transit riders should keep an eye on service updates and potential delays by checking CapMetro alerts before heading out, especially with Memorial Day weekend approaching. If you have outdoor plans this evening, keep a backup indoor option ready in case a stray storm drifts over your neighborhood.
Weekend Outlook
The atmosphere looks busier Saturday, May 23, into Sunday, May 24, with repeated rounds of showers and thunderstorms and the highest rain chances on Saturday. Highs should generally be in the mid-80s, with the kind of humid, unsettled setup that keeps clouds bubbling all day. That pattern is expected to hang on into Memorial Day, Monday, May 25, although rain coverage may back off a bit. Multiple rounds of heavy downpours over the weekend could still trigger localized flooding in poor-drainage spots, so keep an eye on updated forecasts and avoid driving through flooded streets, no matter how shallow they might look.
