Can't help you, unfortunately. I live in sunny SoCal - it was 56F today, and sunny. Went for a nearly 3hr bike ride up a beautiful canyon road. It's really ridiculous how nice it is down here, although the strange downside is that you start beating yourself up mentally every day that you don't ride long!
The worst part of it all is that virtually nobody bike commutes in LA. Traffic's a bear, and it's far from bike-friendly, and drivers are impatient as all heck around rush hour. Total waste of gorgeous weather.
