It is 48°, but the wind is taking it down to 45° on exposed skin. The sky is clear.
The wind backs into the west-southwest around 5 AM, which is the turn that usually comes ahead of the change rather than after it. The first rain arrives between midnight and 1 AM, with the best chance of it around 11 AM. That leaves a usable window outdoors until about midnight, and it closes quickly after that.
Taller, warmer bars mean heavier rain. Dotted means no reading for that hour.
