Overview
- North winds and much drier air arrive Saturday, keeping highs in the mid-70s before a stronger push of cold air drops San Antonio into the low 40s by early Sunday with wind chills in the 30s.
- Parts of the Hill Country fall to the low-to-mid 30s overnight with wind chills in the upper 20s, while San Antonio stays above freezing.
- The National Weather Service issues a red flag warning from 10 a.m. to 9 p.m. Saturday as 15–20 mph winds gust near 30 mph and relative humidity falls near 20%, elevating wildfire danger.
- Sunday tops out in the mid-60s, the coolest afternoon since Feb. 1, followed by another cool day Monday before a rapid warmup sends highs into the 70s Tuesday and mid-80s by Wednesday, with upper 80s possible Thursday pending the next front’s timing.
- February has run unusually warm across South/Central Texas, and CPC guidance gives San Antonio a 47% chance of above-average spring temperatures with precipitation roughly a 50-50 proposition; a warm February often precedes a hotter summer historically, though not always.
