8th Least Snowiest January on Record in Rockford
We did, however, have a surplus of rainfall for the month with a little over two inches falling. This was a little over three quarters of an inch above the monthly precipitation average.
The drastic change from a very snowy December to an unseasonably warm January has to do with the jet stream. The placement of the jet stream over the lower 48 did not allow much opportunity for cold air to be displaced southward. Yes, there were some cold days but the warm days out-numbered the cold days by a significant amount.
A quick glance into the month of February and there are some signs suggesting that the pattern may continue to support a warmer than normal month. Keep in mind that there will likely be colder days throughout the month, but overall there is a slightly higher probability that the month could come in above average.
