Clearing and windy last night, clear, calm, and frosty this morning. First day this winter I've worn (1) wool jersey, (2) tights, (3) jacket. I knew I was on the MUP, despite the leaves, when I hit all the bumps in the pavement.
Just to clarify, I've had 30° temperature changes between morning and afternoon, and 40° from day to day. What surprised me was how fast it dropped -- normally that 30° drop means it drops 4° per hour for 8 hours, rather than 15° in one hour, and then 5° over the next 8 hours.
OT: We had a court case a while back against the engineers who designed a bridge for My Fair City, and couldn't believe the temperature could swing so widely, so fast. A couple years where the temperature swung 40° in 24 hours a few times a year, and the bridge started cracking. I think it was a politically directed contract to some engineer donors who lived on the coast. Either go local or find someone who's smart enough to look at
local conditions!
