The next few hours
Dry for the moment, with rain moving in this morning
It is 57° with a dew point of 50°, which is comfortable for this time of year. The sky is overcast. The air is close to calm.
The wind backs into the east-southeast around 10 PM, which is the turn that usually comes ahead of the change rather than after it. The first rain arrives between 8 AM and 9 AM. That leaves a usable window outdoors until about 8 AM, and it closes quickly after that.
Taller, warmer bars mean heavier rain. Dotted means no reading for that hour.
