A more active pattern takes shape by the weekend.

A high-pressure system is maintaining warm and mostly dry conditions in San Antonio, with temperatures in the 80s and mornings in the 60s. Fog is expected over the weekend, particularly dense on Sunday, while small chances of rain may occur from Wednesday to Friday next week as the weather pattern becomes more active.

Record-challenging heat today

The weather will remain calm with muggy mornings and comfortable afternoons until Friday night when a storm system brings rain to San Antonio. Expect up to a quarter-inch of rain, with higher totals in north Texas. By Saturday afternoon, the rain will clear, leading to a sunny and low-humidity extended weekend, though gusty northwest winds may reach 30 mph.

A slow-moving upper-level trough near Baja California may extend rain chances into early next week, but widespread rain and thunderstorms are unlikely. Temperatures will remain well above seasonal averages with highs in the 70s to low 80s and lows in the 50s, while another weather system may bring more rain later, though details are uncertain.

Overall, the weekend is expected to remain very comfortable and great for outdoor plans.

Temperatures are expected to rise from the low 40s in the morning to the low 60s by afternoon. Rain chances increase starting Tuesday afternoon, particularly out west, with potential heavy rain midweek. The week will see a gradual warming trend, reaching near 70s by the weekend.

But Thursday will be sunny, quiet, and pleasant

A light freeze affects the Hill Country, southern Edwards Plateau, and Rio Grande Plains. Temperatures will rise to the mid 50s and 60s under partly sunny skies, with a chance of spotty showers on Monday expanding southeast by Tuesday.

The day will start with humid air and morning fog, with temperatures soaring near 80. A cold front on Friday brings cooler weather for the weekend, with highs in the upper 50s and gusty north winds on Saturday. Near-freezing temperatures are expected on Sunday and Monday mornings.

A Wind Advisory is in effect for South-Central Texas tonight through noon Monday due to a strong cold front, with north winds of 20-30 mph and gusts up to 45 mph.
