San Antonio, TX – Cool, clear mornings will quickly give way to a warm midweek rebound across South Texas, as temperatures swing from the 40s overnight to the mid-80s by Wednesday, according to the National Weather Service in Austin/San Antonio.

After a crisp start Monday with lows near 41°F, daytime highs will rise to around 64°F, remaining sunny and dry. Winds will shift from light northeasterly to southerly by Tuesday, ushering in much warmer air and pushing highs into the upper 70s by Veterans Day.

Forecasters say Wednesday and Thursday will bring near-record warmth for mid-November, with highs reaching 83–84°F and lows staying in the 60s overnight. The warming trend will hold through the end of the week before a slight chance of showers develops by Saturday.

No major hazards are expected, but residents are advised to stay hydrated during outdoor activities as temperatures climb sharply midweek. Clear skies will continue through much of the period, keeping South Texas dry and pleasant.
