Austin is waking up clear and mild Friday, but the comfortable start will not last long. Temperatures will climb from the upper 60s into the 90s, topping out near 93 degrees under sunny skies, according to National Weather Service. Rain is not expected today, making this another hot October day that feels more like summer than fall.

Sunny, Hot Weather Holds Through Sunday

Friday night should stay mostly clear, with temperatures falling to around 67 degrees. Saturday will bring another sunny afternoon near 94, followed by a mostly clear night around 69. Sunday will bring south winds, becoming south-southeast at night.

Small Storm Chances Return Monday

The pattern shifts slightly Monday, when a 20% chance of showers and thunderstorms arrives after 1 p.m. Temperatures will still reach about 92 degrees, and any rain should remain scattered rather than widespread. Tuesday and Wednesday look mostly sunny and hot near 94, while Thursday brings a better chance of showers and thunderstorms with a high around 91.

Air Quality Alert In Effect

The forecast also lists an Air Quality Alert through Friday evening and says conditions could support elevated ozone levels in the Austin area Saturday. Another Ozone Action Day could be announced by Friday afternoon or Saturday afternoon. People planning long outdoor workouts may want to check air-quality updates first, while combining errands and skipping drive-through lines can help limit ozone pollution.
