CALGARY -- Today’s going to be a little muted. We’re once again into that lee ridge – essentially the "exit region" of an area of high pressure, where northern air will cascade onto us. Therefore chillier conditions will reign abundant, as this particular high pressure ridge’s apex is into the Northwest Territories, which means it will siphon a significant amount of cooler air toward us.

Let's talk daylight. Calgary, at worst, loses 3 minutes, 50 seconds of daylight per day. It does so quite often at this time of year, too!
