Sunday will be hot, with highs near 92 in San Antonio — potentially breaking a record that’s stood since 1908. Gusty winds and very dry air will increase fire weather concerns, especially west and north of I‑35.

A strong cold front moves through Sunday evening, and winds will be from the north, gusting up to 40-50 mph. Temps will plummet and by Monday morning, we’ll be near 40°.

MONDAY AND TUESDAY

After the chilly start, temperatures will struggle to get out of the 50s Monday afternoon.

Monday night will be cold, and by Tuesday morning, many of us will be in the 30s. While we expect temperatures to be well above freezing, there may be a light freeze in the Texas Hill Country.
