Despite the chill, quiet weather is expected through the weekend

High pressure keeping the weather quiet.

A blast of Arctic air will settle into eastern Iowa on the strength of high pressure resulting in a very cold end to the week.

Friday morning will be the coldest in several weeks as temperatures drop into the single digits. There will just enough of a light breeze to produce wind chills hovering around or even below zero for some.

Despite sunshine it won't provide much warmth with high temperatures climbing into upper teens (northwest under snow areas) and 20s everywhere else.

THE WEEKEND
The weather pattern will feature a split flow. The polar jet stream which is an upper-level river of fast wind and usually brings in the cold air during the winter months will be positioned to the north. The sub-tropical jet stream is set up to the south and usually brings moisture into the country during the winter months. Both will be aligned around the central part of the country leading to mostly dry weather.

High pressure will be locked in overheard keeping our weather quiet with the main storm track further south where wintry weather and heavy rains will be likely.

Skies will generally be mostly sunny on Saturday with a few more clouds possible on Sunday. It will be an ideal weekend to hang up any Christmas decorations, lights, get a tree, etc.

High temperatures will moderate a touch returning close to normal by the end of the weekend with readings in the low/mid 30s. Night lows will be cold in the teens.

EARLY NEXT WEEK
The pattern begins to shift to start to the week with a bit of a warm-up, at least for December standards with high temperatures in the 30s and 40s Monday through Wednesday.

Dry weather will be seen across eastern Iowa over the next five days.
