Cool, 6C/43F, overcast morning ride in. Although the roads were wet from overnight showers, the air was dry when I left so I wore shorts and my rain jacket. However, about 5 minutes into the ride, a very light shower (really just spray) came down for the rest of the ride. Fortunately, by that point, my legs were warm from the 5 minutes of riding so for the remaining 25 minutes of the commute, I was fine but a bit cold on the last segment before my office where I'm coasting down a hill for about 500m/yd and then I got a bit cold.
Similar conditions are forecast for the ride home.
