I don't know how that cold snap the other week got the name "polar vortex." We weather people usually associate vorticity with vertically rising or sinking columns of air created by highs and lows. That arctic blast hit us horizontally! Well, no matter what we call it, it looks like it will be back on Monday.

Today, though, should be mild. The normal high is around 19, and our forecast calls for 18-25 for most towns. An Alberta Clipper low will create a 30 percent chance for a trace to 2 inches of snow. The wind will be north-northwest at 5-15 mph.

On Monday, it will get pretty cold again as arctic air masses plunge through our region and deflect the polar jet stream to the south. The morning low will be near 10 below, and the high may hit only 0. The rest of the work week will be cold but yet another warmup should be with us by next weekend.

Five-day forecast
Sunday: Partly sunny with a 30 percent chance of snow showers, high 20 and low -8.
Monday: Partly sunny with a 30 percent chance of snow showers, high 0 and low -20.
Tuesday: Partly cloudy with high 0 and low -17.
Wednesday: Partly cloudy with high 0 and low -15.
Thursday: Partly cloudy with high 3 and low -7.
