Weird variations on the way to work this morning. Got my motorcycle back yesterday

so rode to work in a vest.
At the house, checked and it was 56 in the garage. Seemed like I was in a little cool depression. As I was crossing the 101 on the overpass, significant change in air temp (up) and humidity (down). Very comfortable riding for the next 5-6 miles.
Then I came within 2 miles of the ocean, and suddenly hit a patch of fog. Temp dropped 10-15 degrees, and now my pants are damp from the knees down. Rode about 2 miles in that fog.
Then, suddenly, it's gone. I'm even closer to the ocean now, but it's just gone. Arrive at work a bit chilled, but I will appreciate that sensation later when I head home and it's 90. . .
