The next few hours
Dry for the moment, with rain moving in this evening
It is 36°, but the wind is taking it down to 33° on exposed skin. The sky is mostly cloudy.
Pressure is easing down, 0.03 inHg over the last hour. The wind backs into the north-northeast around 2 PM, which is the turn that usually comes ahead of the change rather than after it. The first rain arrives between 5 PM and 6 PM, with the best chance of it around 7 PM. That leaves a usable window outdoors until about 5 PM, and it closes quickly after that.
Taller, warmer bars mean heavier rain. Dotted means no reading for that hour.
