Storms are likely later this evening and tonight. Heavy rainfall is a possibility.

Storms are expected to bring heavy rainfall to San Antonio late Tuesday night into early Wednesday, with the main risks being street flooding and wind gusts up to 60 mph. Most rain will clear by the Wednesday morning commute, though some road closures may persist. The remainder of the workweek will see reduced rain chances, with a brief return of storms possible over the weekend.

Sunday will be mostly warm and humid with highs in the upper 80s, featuring a small chance (30%) of storms between 4pm and 8pm that may bring heavy rain, lightning, and small hail. Monday will be warmer, near 90°, with only a slight chance for an afternoon storm, while another weather system on Tuesday night into Wednesday could bring widespread rain and possible street flooding before drier conditions return later in the week.

After a stormy Saturday morning in San Antonio, quieter weather is expected for Sunday and Monday of Memorial Day weekend, though isolated showers remain possible. Rain chances increase again Tuesday afternoon through Wednesday with the arrival of another low pressure system. The week will end with drier and warmer conditions.

San Antonio is experiencing another round of storms, with monthly rainfall totals now above 4 inches. While Friday brings a brief lull with isolated showers, heavy rain and potential flooding are possible Saturday due to an upper low, prompting a Flood Watch through Monday. Storms are expected to be scattered, not continuous, making it difficult to predict the heaviest rainfall areas. Conditions should improve on Sunday and Memorial Day, with only isolated rain chances remaining.

As Memorial Day weekend kicks off the unofficial start of summer across the country, thousands are expected to head to the rivers and lakes. This year, conditions are generally favorable for tubing, though water levels remain a bit mixed depending on location.

A break in rainfall, but isolated storms are likely to redevelop later, with another round possible tonight. Street flooding remains a concern as the active weather pattern continues into the Memorial Day weekend.

NOAA forecasts a below-average 2026 Atlantic hurricane season, predicting 8 to 14 named storms, with 3 to 6 becoming hurricanes and 1 to 3 reaching major hurricane strength.
