Regional Weather View.

A complex weather system will pass through the Upper Midwest tomorrow. Warm will push well north ahead of the low. This system has more of an early fall look rather then mid December. The system will likely spread rain well up into Minnesota and Wisconsin, with only the far north experiencing snow with some accumulations. Temperatures as a result of the systems will be in the upper 30s north to as warm as the low 60s in Iowa on Wednesday. Thursday a strong cold front behind it will push much colder air and windy conditions into the region.

Looking Ahead

I really do not trust the long range forecasts at this point, Some days it shows snowstorm chances the next warm December weather. The 1st part of weekend looks dry and cool, with a warm up approaching on Sunday. The models have just brought in the chance for maybe some rain and snow Monday and Tuesday with a system that has more cold air available. Some heavier snow totals are possible. in parts of Minnesota and Wisconsin, including our area. Chilly dry weather moved in for Wednesday the 21st, before the models hint at another system hitting a couple of days later on Friday the 23rd. This one also appears that it may produce a shot at some snow for the local area. Christmas day looks fair for December temps, with a chance of some light snow. Then the models show a warm-up as we start to approach the end of December.
