A cold front is moving through northwest Oklahoma this afternoon. There’s a wide range in temperatures. Part of it is the front. A bigger part of it is the snowcover…
The white isn’t cloud cover, it’s actually snow cover. Note the 41 at Buffalo. That’s behind the front, but also at the core of where the heavy snow hit. Some of those 60s are behind the front–with no snowcover. The 70s aren’t that far away. It could even be argued that northwest winds blowing over that snow cover will give the front an extra bite to it. We look for that with arctic fronts in winter. When we have a lot of snowcover over the northern and central Plains, the wind blowing over the snow cover behind the front reinforces the cold air, so that when it moves into the lower latitudes, it still has a punch.
