WINTER WEATHER ADVISORY SATURDAY FOR SNOW COLD WEATHER ADVISORY SATURDAY NIGHT AND SUNDAY Our 17-day onslaught of winter weather ends with a bang this weekend, one that features another snow system over the south and a quick but intense shot of Arctic air. For perspective, since Thanksgiving, the majority of my area has seen 10–22 inches of snow. That does not take into account what ends up falling today. Here's a larger perspective of 14 day snowfall totals, which shows the

Thursday was a tale of dry air as far as my area was concerned. Models really struggled to define its southern extent and the impact it would have on snow. In the end, it was further southwest than expected by at least 30 miles. That made a difference, with most of the accumulations, (which were generally in the 1-3 inch range) ending up just SW of the Quad Cities. The largest totals, in spots, could have hit 4 inches in the blue-green shading below from near Williamsburg to

The first of two clippers is bearing down on the region as it zips steadily southeast.

We've been in the throes of winter recently, with one of the coldest and snowiest starts to the season in decades. Here's the snow that's fallen the past 2 weeks. Many of us have already seen more than we did all of last year, and it's not even winter yet! Here's the temperature departures, which are running 9 to 11 degrees below normal per day over that same stretch of time. It's reminiscent of the winters of the late 70s, which were epic in every sense of the word for those

After the warmest day in two weeks, temperatures are on their way down again thanks to the passage of a strong clipper. Rapidly rising pressures on its backside and stout cold air advection will drive winds that at times early Wednesday may gust as high as 45 to 55 mph. The HRRR shows gusts around Sioux City as high as 61 mph. That meets severe thunderstorm criteria. Along with the winds will come a shot of colder air that overspreads the region Wednesday morning.
