Good Saturday bloggers,

It was a cold and frosty start, but it will end up being a nice December day with highs in the upper 40s to low 50s. We have a blast of cold for early next week, but it won't last long. The Polar Vortex will stay in eastern Canada as a piece of it drops into the upper Midwest and Great Lakes early next week. Then, the piece will rotate back north quickly, putting the USA in flow from the Pacific Ocean by Thursday. This is why our blast of cold is short lived.

TODAY-SUNDAY: Today will be sunny with highs in the upper 40s to low 50s. Tonight we will see the clouds increase as the wind picks up from the south at 10-25 mph. This will keep lows at 40°-45°. Sunday will see lots of clouds, but remain mild with highs in the low 50s. If we see some sun highs will reach the mid and upper 50s. Also, a period of mist or drizzle is possible with amounts no more than a trace.

MONDAY MORNING: A strong cold front will be approaching as we start the day in the 40s. The system with this front is quite disorganized, so we do not expect any measurable precipitation with the front.

MONDAY AFTERNOON/EVENING: The cold air will rush in on northwest winds at 15-30 mph. Wind chill values will drop to the single digits by evening. Flurries, a period of very light snow or drizzle is possible as the cold air rushes in. We do not expect slick roads. We will watch it, because if we see more than a trace, we could have slick spots. The chance is 20%.

TUESDAY: We will start in the teens ahead of a second reinforcing shot of cold air. This second front will arrive by afternoon, keeping us in the cold air, so highs will be 25°-30°. Flurries may accompany this second front. So, at this time we do not expect much or any snow with the fronts.

WEDNESDAY: Highs around here will be in the 20s, with highs staying below zero across Minnesota and Wisconsin. Now, take a look across western Kansas, highs in the 50s. This milder air will be heading our direction by Thursday and Friday, so our blast of cold lasts about 2 1/2 days.

Have a great weekend.
