We hope you have been enjoying the nice December temperatures we have been experiencing the last few days.
A cold front moves in tonight, but it will come with little fanfare. Winds will switch to the north tonight, and knock temperatures down 10°-15° Friday. Lower 30s are typical temperatures for early December standards.
A southerly wind moves in Saturday and Sunday, giving our temperatures a boost into the 40s.
The arctic air is currently bottled up in Canada, near the Arctic, of course.
Cold air stays in Canada for the weekend. If you haven't put out your outdoor Christmas decorations, these weekend may be the time to do it. Although, it will be a bit breezy on Saturday, but it's a "warm" breeze.
The jet stream digs farther south, bringing the cold air with it. This sends the arctic cold front through Iowa on Monday, perhaps producing scattered snow showers. This will bring in windy conditions, making it feel even colder as the coldest air for eastern Iowa moves in Tuesday and Wednesday.
High temperatures Tuesday and Wednesday will be in the teens and lower 20s, with lows in the single digits. Wind chills will likely drop below zero during this time.
