Austin started Thursday, April 23, under a blanket of low clouds and muggy air, with temperatures hovering around 70°F and dewpoints in the upper 60s. Patchy fog could slow the 8–9 a.m. commute in some low-lying spots before it lifts, and this afternoon is set to warm up to a high near 85°F. South winds will generally run 5–10 mph, with gusts later in the day that could reach around 25 mph.

Fog And Afternoon Gusts

Patchy fog may knock visibility down to a half mile or less in low-lying neighborhoods and along the escarpment during the morning drive, but conditions should improve by late morning. By afternoon, southerly winds are expected to pick up, with gusts up to about 25 mph that can rattle lightweight outdoor items and make a bike ride feel like extra work. There are no watches or warnings in effect at this time, according to the National Weather Service Austin/San Antonio.

From Storms To Sun

If you got caught in the soaking showers earlier this week, the change will be noticeable. Forecast guidance has shifted from a soggy setup to a drier, warming pattern as the week goes on. For a refresher on the recent wet stretch, check out how Austin fared as storms snarled the commute.

Heat Builds Into The Weekend

Temperatures are expected to climb into the low 90s on Saturday and Sunday, and the National Weather Service notes that heat-index values could reach or exceed 100°F in parts of the I-35 corridor and Coastal Plains, especially during the hottest afternoon hours. Monday and Tuesday look even hotter, with daytime highs approaching the mid-90s, so it is a good idea to plan outdoor work and activities with the rising heat in mind and keep an eye on updated forecasts.

How To Prepare

Shift strenuous outdoor activity to the morning or evening, stay hydrated with plenty of water, and check in on people who are particularly vulnerable to heat. The City of Austin maintains heat-safety guidance and a list of cooling locations. See the City of Austin for cooling-center locations and tips if you or someone you know needs relief from the heat.
