Weather Alert – Severe storms and flooding tonight

Welcome to May, the windiest month of the entire year. Mother Nature is wasting no time in putting us in the crosshairs of the threat of severe weather and flash flooding that will unfold later this afternoon and into the evening/night hours. Here's what you need to know.

Two rounds of storms are possible

This event can be divided into two parts, the first developing this afternoon and evening, and the second taking us during the early morning hours of Thursday.

Round 1 – Isolated severe storms in the afternoon

The first half of Wednesday will be quiet with humidity steadily increasing between now and mid-afternoon. As we reach the heat of the afternoon, intermittent showers will begin to develop into severe thunderstorms. It's difficult to tell you exactly where these storms develop ahead of time, but our entire region should be watching because these storms will be able to produce large hail, damaging wind gusts, and an isolated tornado.

The second round – in the evening and night, severe storms and floods

The second batch of storms will likely be more widespread with additional severe weather concerns and an increased threat of flash flooding. Early this evening, we will head toward West Texas and the Hill District where the most widespread storms will develop first. These will move slowly to the east, perhaps in two waves, until 5-6 a.m. Thursday.

In addition to the threat of large hail, damaging wind gusts, and an isolated tornado, the flood risk has been increased to at least Level 2 from 4. However, the eastern two-thirds of our region is now below the rarefaction level. 3 out of 4 Flood risk. The tropical nature of our atmosphere will contribute to increased precipitation rates at times, and areas that experience multiple rounds of storms could see 4 to 5 inches of rain in a very short period of time. It's nearly impossible to predict in advance where these high totals will occur, but we'll all need to be careful of flooded roads through Thursday morning.

Additional storm chances this weekend

Some additional disturbances coming into Texas over the end of the weekend will increase storm chances at times. At this point, nothing after today seems to matter in the severe weather department, but it can't be ruled out sometimes. Friday and Sunday come with storm chances rising by 50%, although the timing and coverage of those chances are still subject to change.

Summer heat next week

Storm chances end Sunday with summer temperatures and humidity set to rise afterward. Highs in the low to mid 90s could come next week with heat index temperatures over 100 degrees.

Phase 2: Water restrictions continue

Lake Travis drops at 630.29 feet (38% full, 37.5 feet below average)

Lake Buchanan is steady at 995.46 feet (48% full, 16.5 feet below average)

Combined storage remains less than 900,000 acre-feet. The second phase of water restrictions has begun and will continue for the foreseeable future. Please conserve water and follow your local watering restrictions
