Trending drier, hotter into the weekend

AUSTIN (KXAN) — After a wet and relatively cooler start to the work week, rain chances begin to thin some, kicking off our next warming trend.

A stalled boundary just to our south will be the focus for initial storm and shower development today… but the heating of the afternoon will allow for a few more spotty showers further north. With fewer showers and storms and more sunshine in today’s forecast, afternoon highs will be a little warmer with most areas topping out in the low to mid-90s.

Thursday and Friday will be similar with spotty rain coverage (20%) and hotter temps (mid-90s). Between today and Friday, most additional rain totals will fall short of 0.5″.

Mainly dry weather returns this weekend, then rain chances increase next week as a slug of tropical moisture moves over Texas from the Gulf. Wetter, cooler than normal weather is forecast to continue in our 8-14 day forecast during the first week of September.

Monday flooding

The Shoal Creek watershed in Central Austin received as much as 4.96″ of rain in just 2-3 hours on Monday, causing the creek to spike to 16.37 ft. deep at 12th Street — the highest crest since 2015 and fourth-highest on record. Camp Mabry and Austin-Bergstrom shattered daily rainfall records, and Camp Mabry set an all-time hourly rainfall record with 2.96″ of rain between 4-5 p.m.
