Happy New Year,
The first morning of 2013 was very cold. Skies quickly cleared around 4AM and the temperatures dropped rapidly. Icy spots were numerous but because many were still at home in bed, there were very few car crashes across the metro early this morning. Here is a look at morning lows.
Even colder air was over northern Iowa where Fort Dodge dropped to 8 below zero. We are forecasting 9 for a low on Friday morning but it may be even colder than that. January is defintely starting cold, continuing a weather pattern that started around the 23rd of December. Even though we had some cold days to finish up December the month ended up warmer than average.
Here is the December recap I showed on the air this morning.
The warmest day was on December 4th when the temp hit 74°. The coldest morning was December 26th. Yesterday, at KCI, 2.1 inches of snow was measured. At KCI the snowfall total that will go into the weather records for December 2012 will be 4.6 inches or two-tenths of an inch below average. Rain and snow combined and melted down measured 1.34 inches of precipitation. That marked the ninth month in a row the total precipitation was below average.
The recent cold air outbreak we have experienced has been the result of the Arctic Oscillation going negative. It appears the weather pattern may be shifting over the next week. This shift should allow warmer temperatures to return and the warmer temps may be here as soon as this weekend. Below is the forecast 500mb map for this Saturday.
A weak storm will drag a weak cold front through the region Saturday. Notice the warmer, more orange colors over the desert southwest. That airmass should shift into our area late in the weekend and into early next week. It appears at this point we will make a run at 50° by next Tuesday.
Have a great first day of 2013!
