Does cold have a smell?

Tonight is another exceptionally cold night, down into the 20s (Fahrenheit), and both last night and tonight I feel like there's a smell seeping into the house from outside and that smell is ... the smell of cold. Turning up the heat dissipates it. Furthermore, the smell of cold makes my sinuses ache and eventually triggers an allergy attack. Unless I'm just crazy.

These 26- to 28-degree lows are exceptionally cold not just for March in Washington, but for anytime. We usually do get freezing temperatures at some point during the winter, but not much below freezing and not for very long. We are more likely to hover around 30 to 34, which is we we get so much freezing rain, snow mixed with rain, and all that good stuff.

But this is not winter. The thing that is making it cold is the lack of clouds. I don't know how it works in other climes, but around here cloud cover acts like a blanket, holding warmer air down near the earth. With no blanket of clouds, we shiver in the cold, just like someone with no blanket in bed.
