Austin is waking up cloudy and muggy, with temperatures hanging near 75°F and dew points in the low 70s that make the morning commute feel heavy and sticky. The warmup will not take long. Highs this afternoon will climb into the mid-90s, and many neighborhoods will see heat-index values pushing near or above 100°F. South winds stay light around 5–10 mph, so the real story today is the heat and humidity, not the breeze. Overnight lows only slip back into the mid-70s, which means very little relief after sunset.
Forecasters expect this pattern to hold through Tuesday with another very hot day on tap. NWS Austin/San Antonio keeps highs in the mid-90s and heat-index readings up to about 103°F along the I-35 corridor. There are no watches or warnings in effect right now, but the heat itself is the main concern for the week. If you work outside, try to tackle the heaviest tasks early in the morning or in the evening, drink water often, and check in on older neighbors and pets.
Storm Chances Climb Midweek
Rain chances stay low Monday and Tuesday, then start to edge up on Wednesday. There is only a slight shot at showers or storms Wednesday afternoon, with better odds arriving Thursday night into Friday. That is when showers and thunderstorms become most likely, and a few storms could be strong with locally heavy rainfall and gusty winds. Once that front pushes through, look for a noticeable cooldown into the weekend with highs dropping back into the 60s and 70s.
This warm stretch has been building for a while, and we first walked through the setup earlier this month. For background on how the pattern developed, see fog then bakes. For the most up-to-date watches and short-term updates, check the National Weather Service before heading out. Keep your phone charged for alerts, and if heavier rain or gusty winds are in the forecast later in the week, consider moving or securing outdoor furniture.
Quick Tips
To beat the heat today, stay hydrated, avoid heavy exertion in the mid-afternoon, and take regular breaks in air-conditioned spaces when you can. If you have outdoor plans later this week, line up a backup plan. Scattered storms are most likely Thursday night into Friday, so keep an eye on local forecasts and mobile alerts for any last-minute changes.
