Enjoy the sunny and relatively warm weather this afternoon, because a visitor from the North Pole will bring us the gift of Arctic weather tonight. Today's high will be right around the mid-December normal of 43 degrees, but that is not going to be the case tomorrow.

An Arctic front will pass through the region late tonight. Some snow showers might form ahead of the front, especially east of the city, but no accumulation is expected. What is expected is the arrival of a very cold air mass. The temperature will drop to the lower 20s overnight and not get much warmer during the day tomorrow. Strong northwesterly winds blowing at 25-30 miles an hour will push the wind chill down into the single digits all day. Light snow flurries are possible on Thursday but they won't amount to much.

A weaker second front will arrive early Friday morning, plunging the low into the mid teens in the city which will feel closer to zero degrees when you factor in the wind. With that additional jolt of cold air Friday will stay in the brisk mid 20s.

The abnormally cold weather won't last too long, as the cold high pressure system will be pushed offshore on Friday by a storm crossing the Great Lakes. The temperature will start going up late Friday night. As the temperature rises precipitation will fall, first as a couple inches of snow followed by a rainy Saturday and Sunday. Saturday should warm to the mid 40s and Sunday to the lower 50s before the next cold spell hits early next week.
