From the KX Storm Center:
It is not over yet. It is back to winter weather & frigid temperatures. There is a little bit of silver lining when it comes to our temperatures. It will not come until Saturday afternoon & into Sunday. Temps will warm back into the 20s & 30s, briefly. All of these changes will happen here, during the next 72 hours.
There is a wind chill warning in effect through tonight, until Saturday at Noon (CST). The warned area includes Northwest ND (to the Missouri River) North Central ND and most of Eastern ND. This warned area includes Lake Sakakawea. Expect wind chills to fall to below zero. Frostbite will be possible in as little as minutes, to exposed skin.
There is a wind chill advisory in effect for much of Western & Central ND until Noon Saturday. Chills from 25-40 below zero are expected. Frostbite will be possible in as little as 30 minutes to exposed skin.
There is a ridge of high pressure over the Northern Plains and parts of the Great Lakes Region & Midwest. This high will push NE and back over Canada. The lack of an Arctic air mass will allow temps to warm up to near average for this time of the year, Sunday. But this warm up will not be long lived. And changes to our forecast have to do with a low pressure system over the Pacific Northwest & SW Canada. This low is just moving inland, from the Pacific Ocean. It will continue to move East & NE, breaking up as it crosses the Mountains. It will redevelop over over Eastern MT & Southern Canada. As this low moves East & NE, a warm front will move through the Dakotas on Saturday. Not long after, a cold front will dig into the Dakotas from the North. This system will bring a couple rounds of scattered light snow. The first will be Saturday night with the warm front and a second round with Sunday's cold front.
On the back side of our weekend low, expect another surge of Arctic air. It will get dangerously cold again through the beginning of the work week. There will be a few more chances of snow during the next 7 days, but we are not looking at much in the way of totals. Temperatures will warm to near average highs/lows on Wednesday. Thursday & Friday of next week
Tonight, mostly clear and bitterly cold. Lows in the -20's & a few -30's with a NW/SE wind 2-10mph. Chills in the -30's & -40's.
Saturday will be mostly sunny with clouds rolling in & snow chances, late. Highs in the single digits with a South wind 5-15mph gusting near 25mph at times. Chills in the -teens & -20's.
Saturday night will be the least cold night through the beginning of next week. It will be mostly clouds with scattered snow possible. Lows in the single digits with a South/West wind 2-12mph & a little gusty. 30% chance of snow and chills below zero. Light totals will be possible through Sunday.
Sunday, mostly cloudy with scattered snow. It will get warmer before a cold front brings another blast of Arctic air into the area. Highs in the teens & 20s with a NW wind 10-20mph gusting near 30mph. 30% chance of snow with light totals.
Sunday night, clearing and much colder. Lows in the -teens with a NW wind 5-15mph G20 and chills dipping back into a dangerous range.
