Pre-Christmas "Wishcast"

Snow depth map (snow on the ground) as of noon, December 22, 2012.

While this is a "scientific" forecast in the sense that it is made by a reputable computer model (NWS GFS), the models have had an unusually difficult time with the pattern change across North America that is trying to occur. One run will bring moderate to heavy snow, the next run nearly nothing. Thus, "wish casting" (as in, "I'm dreaming of a White Christmas...").

Anyway, Dr. Ryan Maue generated this graphic. The orange area in the central Plains is more than a foot of snow on the ground at that time!


  1. I find this interesting. If I go to the NWS, they are only forecasting a slight chance of snow for Sunday. They only go out 7 days in their online forecasts, with no more snow forecasted.

    Accuweather doesn't show any snow for this weekend, but they are forecasting snow on the 21st.

    So would we be looking at just one big snow storm then?

  2. Looks like this won't happen. Accuweather is now forecasting now precip in the next few weeks. We need something to fall from the sky.

  3. Well Justin, it was called a "wishcast"... seems that storm #4 is our only hope now and it's over 10 days away.

  4. We have a chance late this week and again next week.
