DECEMBER PACKING UP...

The sun was back out around the region Friday as Thursday's snow system spun off to the east. It was more of a sloppy inconvenience than anything else with only minor travel issues due to warm ground and air temperatures. (Ground temperatures at the 2.5 inch depth Friday were reported to be 35 degrees in Cedar County). The heaviest snow totals were found in EC Iowa into NW Illinois, with some as large as 5 inches. Lowden, Iowa reported 5.3, the Dubuque airport 5.1, with Galena and Mt. Vernon at 4 inches. The general range across my area was 1–3 inches.

Here's some individual plots.

With clouds parting, the visible satellite shows three different patches of snow cover from 3 different events encompassing a five-day period.

With only 2 days left in the month, December is packing up and departing on what appears to be a rather subdued mood. The only issue (and it's a minor one) could show itself Sunday morning when an upper air low crosses the Midwest. Most of the forcing will be found in the north, but some snow showers could make it as far south as I-80 Sunday. With marginal temperatures in play, accumulations will be light, if there are any at all. Here's what guidance is currently suggesting for totals. There is still some minor disagreement on the precise track with GFS further north.
