Tuesday forecast for Austin: Good morning and happy muggy Tuesday to you! No, it’s not you, it really is 74 degrees (at Camp Mabry) at 6 a.m., which is about 10 degrees higher than normal for this time of year. You can blame the increased cloudiness and higher levels of heat-trapping humidity on south-southeast winds bringing in Gulf moisture. And it’s these warmer conditions that set the stage for some isolated storms expected later in the day.
According to the National Weather Service, severe storms will be possible along and west of the Interstate 35 corridor Tuesday afternoon and evening. Forecasters say the greatest chance for severe storms will be on the Edwards Plateau and in the Hill Country. The main weather threats will be damaging winds with gusts of up to 60 mph and large hail, with some stones as large as tennis balls.
Heavy rain could occur, but not enough to warrant a flash flooding warning just yet, forecasters say. Some spots west of the Austin metro area could see more than 2 inches of rain. The weather service says the storms should weaken by midnight as temperatures decrease during the evening.
Tuesday’s outlook for Austin calls for unseasonably high temperatures that could climb to near 91, only 5 degrees shy of the daily record. But when the heat is coupled with the increased humidity, the heat index value could rise, making it feel more like 97 degrees outside, forecasters say. South-southeast winds of 10 to 15 mph in the afternoon could ease some of the mugginess, especially with gusts as high as 20 mph.
Looking ahead to the rest of the work week:
- Wednesday’s forecast includes a 20 percent chance of showers and thunderstorms under partly sunny skies with a high near 88. South-southeast winds will continue at 5 to 15 mph. By Wednesday night, rain chances linger at 20 percent under mostly cloudy skies with a low around 70.
- Thursday will be mostly cloudy, the weather service says, with a 30 percent chance of showers and thunderstorms and a high near 85. By Thursday night, rain chances ramp up to 40 percent under mostly cloudy skies and a low around 67.
- Friday’s outlook calls for a 20 percent chance of showers and thunderstorms under partly sunny skies with a high near 85. Winds become north-northeast at 5 to 10 mph. Friday night should be partly cloudy with a low around 65.
