A Lot of Cold...Some Snow

The arctic cold front swept through the area on Sunday morning, and has dropped temperatures anywhere between 25° and 40° from late Saturday evening.

Temperature difference 9PM Saturday 12/28 vs Sunday 9PM 12/29

Temperatures Sunday night will dip well below zero, and factoring in the wind chill it will feel more like -15° to -30° which has prompted a Wind Chill Advisory through noon Monday.

The cold will stick with us for much of the week.  We'll also be stuck in northwesterly flow which is going to bring multiple clipper systems through the area.  The first one is set to arrive later tomorrow afternoon and evening, which could drop up to an inch of snow north of the Quad Cities, perhaps an isolated inch and a half or two inches.  Here in the Quad Cities I think a good half inch or less can be expected.  Here's the RPM model output:

Most times these clipper have very limited moisture and are fast movers so they don't really drop too much snow.  However, a stronger disturbance will move through later Tuesday through much of Wednesday that has the potential to drop a few inches of snow across the area.  However, there is some disagreement with the track and exactly where the heavier band will set up, so stay tuned to the CBS4 Weather Team for updates!
