December has been pretty mild around these parts, but it is going to end much colder. In my area we've had five days of 50 degree + days. That has lead to temperatures running around five degrees above normal.
The warmth is going to continue for the next few days in the Midwest. Monday is going to be one of the warmest days of the week:
A ridge will remain in place through Thursday before the next storm moves through the area.
The warmth hasn't allowed for much snow around much of the Midwest. December is typically the snowiest month of the year, but we are pretty far behind...
There are even portions of Iowa that haven't had any measurable snow! Some stats from the National Weather Service in Des Moines:
Now there are still some question marks about snow later this week, but there is no question about the cold. We will go from temperatures 10 to 20 degrees above normal to 10 to 20 degrees below. Here are the temperature departures for Thursday... then Sunday:
There will be a winter storm that moves through the Upper Midwest Thursday into Friday, but the track is still in question. As we get closer to the end of the week the track will become more clear and we'll be able to narrow down where the snow will fall. Regardless of where the snow falls it will be a frigid Christmas weekend.
Enjoy the mild air before the bottom drops out...
