December 3, 2013
So this is the first week of December, and this is when “changes” are supposed to occur and they are.
Here’s a look at the latest Winter Storm Warnings and Winter Weather Advisories:
The Winter Weather Advisories have been extended south since early Tuesday morning to include parts of south central and southeast KELOLAND. While I don’t expect much snow to fall Tuesday, I think there will be an area that develops in south central SD and moves east overnight. This is being shown on Monday night’s run of the European and Canadian models. Tuesday morning’s run of the new American model is also hinting at that. So a good band of three to six inches is not out of the question from south central South Dakota to southwest Minnesota.
Once the snow moves through, the bitterly cold air takes hold. Raw numbers suggest below zero lows for much of KELOLAND. With snow on the way, these numbers will be even colder as it takes a least a day for models to adjust to the new snow pack.
As we try to “warm” on Sunday, there will be another shot of snow. This is typical when you get warmer air to overrun cold air. Exactly how much remains to be seen.
The cold will stay as we go through much of next week.
How’s that for “changes”?
