The Extreme Cold Returns this Weekend

Temperatures expected to fall 50 degrees from Friday.

The first 10 days of February started off warmer than normal, but since then things have gone downhill. Sadly, after the gorgeous Friday, we have another round of arctic air as the extreme cold has made reservations for the weekend in the Sioux Empire.

A cold front will move south through the area overnight Friday into Saturday morning. This front will shift winds to the north and pull down colder temperatures from Canada. Clouds are likely to stay around through most of the day. However, temperatures will likely fall through the day with the highest temperatures occurring during the mid-morning hours. By the afternoon and evening a high pressure system from Canada will move in clearing us out. However, that high pressure system will bring us even colder temperatures overnight with low temperatures fall from 0 to -15°.

Winds on Saturday are expected to increase through the day and will be strongest during the late afternoon and evening hours. Sustained winds of 20 to 25 mph are expected and gusts of 30 to 35 mph are likely, which will bring in even colder air as well as create a bitter wind chill.

Wind Chill Advisories will go into effect at 9 p.m. for much of the area on Saturday. For those to the southeast the advisories will kick in at midnight Sunday. This means wind chills will be at or below 25-below zero. Some places might even see values of 40-below!

Wind chills this cold are extremely dangerous. Areas of northeastern South Dakota will see the coldest wind chills near 40-below. Wind chills this extreme will lead to frostbite in as little as 10 to 15 minutes. Make sure to bundle up and cover as much skin as possible. Limit your exposure as much as you can. Another thing to remember is that animals are exposed to this cold as well. Make sure to limit their time outdoors as well!

Sunday temperatures will stay in the single digits and for some areas north of US-212 may even stay at or below zero. Wind chills through the day will likely stay below zero before warming up on Monday. The next seven days all look to be below average, but after Sunday things look to tick up. The upper 20s and 30s are expected for Monday and Tuesday before another little blast of cool air.
