First 100 today here in Austin. It still feels like a furnace outside, at 5pm it was brutal.
In Jan and Feb, average highs go from the low 60s to mid 70s, but it can get below freezing on a decent number of nights, and we can also have highs into the 80s under the right pattern. On average, there's maybe one or two winter weather events of some type where there's some sleet or freezing rain. Dallas isn't too far away and they have one or two more significant winter events per year.
