Thunderstorms are likely after 3 PM across the Austin metro, and this briefing walks you through exactly what to expect, hour by hour.The day starts mostly sunny with a high near 83°F — close to seasonal for mid-May in Central Texas. But west-southwest winds of 17 to 22 mph are already building through the morning, gusty enough to affect cyclists, outdoor workers, and anyone with loose gear on a patio. Handle that before you leave.The storm window opens between 1 and 3 PM with passing showers possible. After 3 PM, thunderstorms become likely — not just possible. Central Texas convective storms can trigger earlier or run later depending on how fast the atmosphere destabilizes, so don't count on squeezing in outdoor plans at 2:30 and expecting to be safe. Umbrella is non-negotiable by afternoon; a light jacket helps if you're moving between air conditioning and a storm.No confirmed flash flood alert is in place today, but rainfall totals from these storms are not fully resolved yet. If you're in a low-lying area of the metro, monitor conditions through the afternoon — Austin's geography can turn moderate rainfall into a localized flood event quickly.Looking ahead, heat and humidity build through mid-to-late week, with highs pushing toward the upper 80s and low 90s. May is peak thunderstorm season in Central Texas, and today's pattern is likely the setup for more to come.
