Rain Chances Rise Sunday–Monday in San Antonio as Cooler Pattern Takes Hold

A strengthening low-pressure system follows a weak front that ended the week's unusual heat.

Overview

  • Saturday stays mostly dry in San Antonio with only isolated showers possible and highs around 76–78 degrees after a morning near 60.
  • Clouds increase Sunday with scattered drizzle and showers, a 30–40% chance of rain, and generally light totals under a quarter-inch.
  • Rain probabilities climb to about 50–60% Monday morning into early afternoon, and a few stronger thunderstorms are possible with a low flood risk for South Texas.
  • Heavier rain is forecast for the northern half of the state, where areas such as Waco, Dallas–Fort Worth and Abilene could receive 1–3 inches and face isolated flooding.
  • Most areas dry out Tuesday before a stronger front late Tuesday into Wednesday brings cooler highs in the upper 60s and a sunny, seasonably cool Thanksgiving with morning lows in the mid to upper 40s.
