They're calling for a high of 13°F here on Tuesday with NW winds of 15MPH. That'll kick off some lake-effect snow too.

What I've found is that cold and layering hit me in steps. It's not a smooth curve. For me, there's not much difference between mid-20s and the middle teens. So ordinarily, I wouldn't be worrying over 13, maybe just stepping up to my lobster gloves.

However, with as warm as this season has been, I've not had the opportunity to acclimate to the cold. I'll probably wear what I usually do for the single-digits, which ordinarily gets me down to the minus single-digits without much problem.

But, you've also heard me harp on sweat management in the cold. Sweating in the cold is the first step towards hypothermia. And the colder it gets, the more important it is that I don't sweat. So I'll be giving it a good think before I leave for work on Tuesday as well. I'd rather err on the side of slightly too cold, which I can compensate for by pedaling harder. The colder it is, the harder it is to compensate for dressing too warm and sweating.

What that translates to is that I'll make sure my feet and hands are warm with an extra pair of socks, and my lobster gloves. But instead of a whole extra layer on top and a whole second pair of tights like I would in the single digits, I may add just armwarmers and kneewarmers under my other stuff. And I may close my pit-zips.

It's the first workday of the week for me, so I'll have the panniers on and can carry extra layers with me for the ride home in case I misjudge on the way to work. Then again, the ride home will be with a tailwind.
