We're having same kind of switches in midwest. Yesterday I rode to church in 33 degrees w/ a little bit of snow... but came out of church to 22 degrees. Fortunately there was enough salt and dirt so things weren't glare-y, but it was 8 below this morning at the airport, with another dusting of snow... so I was on the bus. I did drag the trainer upstairs so perhaps tonight or tomorrow night it'll get set up...
