ELEVATED FIRE DANGER
The combination of hot temperatures, low humidity, and dry ground is raising concerns for elevated fire weather conditions, especially this weekend. Relative humidity will drop below 30% across most of the area today and Sunday with slightly breezy winds.

WARM PATTERN CONTINUES
The heat doesn’t end with the weekend. A weak cold front will slide into North Texas late Sunday night but is expected to stall before reaching much of South‑Central Texas. While this may knock temperatures down slightly, we’ll remain warm and dry.
