Weather musing, and poor insulation

It's lovely and sunny today. I was just out on the patio working on some outdoor projects; I was wearing a sweatshirt, but no jacket or hat, and the temperature seemed perfect.

Then I came inside to write about our snowstorm of a few days ago, and looked up the weather. NOAA reports it's 23°F at Los Alamos airport, last reading half an hour ago. Our notoriously inaccurate (like every one we've tried) outdoor digital thermometer says it's 26°.

Weather is crazily different here. In California, we were shivering and miserable when the temperature dropped below 60°F. We've speculated a lot on why it's so different here. The biggest difference is probably that it's usually sunny here. In the bay area, if the temperature is below 60°F it's probably because it's overcast. Direct sun makes a huge difference, especially the sun up here at 6500-7500' elevation. (It feels plenty cold at 26°F in the shade.) The thin, dry air is probably another factor, or two other factors: it's not clear what's more important, thin, dry, or both.

We did a lot of weather research when we were choosing a place to move. We thought we'd have trouble with snowy winters, and would probably want to take vacations in winter to travel to warmer climes. Turns out we didn't know anything. When we were house-hunting, we went for a hike on a 17° day, and with our normal jackets and gloves we were fine. 26° is lovely here if you're in the sun, and the rare 90° summer day, so oppressive in the Bay Area, is still fairly pleasant if you can find some shade.

But back to that storm: a few days ago, we had a snowstorm combined with killer blustery winds. The wind direction was whipping around, coming from unexpected directions -- we never get north winds here -- and it taught us some things about the new house that we hadn't realized in the nearly two years we've lived here.

[Snow coming under the bedroom door] For example, the bedroom was cold. I mean really cold. The windows on the north wall were making all kinds of funny rattling noises -- turned out some of them had leaks around their frames. There's a door on the north wall, too, that leads out onto a deck, and the area around that was pretty cold too, though I thought a lot of that was leakage through the air conditioner (which had had a cover over it, but the cover had already blown away in the winds). We put some towels around the base of the door and windows.

Thank goodness for lots of blankets and down comforters -- I was warm enough overnight, except for cold hands while reading in bed. In the morning, we pulled the towel away from the door, and discovered a small snowdrift inside the bedroom.

We knew the way that door was hung was fairly hopeless -- we've been trying to arrange for a replacement, but in New Mexico everything happens mañana -- but snowdrifts inside the room are a little extreme.

We've added some extra weatherstripping for now, and with any luck we'll get a better-hung door before the next rare north-wind snowstorm. Meanwhile, I'm enjoying today's sunshine while watching the snow melt in the yard.
