With Cody's post below about how snow cover influences temperatures... I'll move on to more warmth discussions as well as a discussion about clearing and snow potential this week. We're starting to see signs on snow this weekend.




Clearing:




We all want it - unfortunately only people in western South Dakota had it today... that'll change for the most part by midday tomorrow, but we were stuck with it today.




Here's what it looked like in Murdo this past afternoon, where they are probably wondering what the problem was with a lack of sunshine...







Then, you can contrast that with clouds toward the East in Watertown, along with some blowing snow:


You can almost *see* the temperature contrast from west to east, and that'll be hanging around for a while - but the good news is that the colder temperatures will gradually become warmer through Wednesday.

We mentioned the chance of snow, too, so here is what we are thinking about that... it's just recently started showing up on our extended computer models centered around Sunday (at least the best chance for accumulation). If you look at our 7-day forecast we show it starting on Saturday afternoon in Sioux Falls and lasting into the morning hours of Monday. Most likely it won't take up that whole time period, but right now the models are very vague in timing and intensity. Right now it looks like some snow will build in and it looks like a couple inches at most for most people out there. Stay tuned for further updates on the snowfall potential!
