When the clock strikes 9 o'clock Tuesday morning, the Twin Cities will go into hunkering down mode as a wind chill warning will make going outside an overwhelming battle against record low temperatures and wind chill extremes.
It'll be a 48-hour deep freeze of notable proportions as it hasn't been this cold in the Twin Cities since Feb. 2, 1996.
A wind chill warning means the "feels like" temperature outside will be at least 35 below zero, creating dangerous and even life-threatening conditions for anyone outdoors for a prolonged period of time without proper clothing, according to the National Weather Service.
Wind chill values will be bitterly cold all day Tuesday in the 25 below to 35 below range. By 6 p.m. Tuesday, the bottom will begin to really drop as wind chill values nosedive from 40 below to 50 or even 55 below in the Twin Cities.
In western and central Minnesota the wind chill could reach a barbaric 65 below.
The worst of the cold will be from about 6 p.m. Tuesday through 9 a.m. Wednesday. After that, the wind chill will remain 30-40 below zero in the Twin Cities until Thursday morning.
The actual air temperatures on Wednesday and Thursday mornings could be break records. In the Twin Cities, the record for Wednesday is 30 below zero and the record for Thursday is 27 below zero. The forecast low for each day is currently -28F.
In north-central and northeast Minnesota the wind chills could get close to 70 blow zero tonight into Wednesday morning.
The good news is that this cold stretch will last just three and a half days before warmer air returns. According to the NWS, this Arctic outbreak will likely rank in the top for cold temps and wind chills, but its "longevity does't even rank in the top 25 for sub-zero stretches."
Winter weather advisory
In addition to the frigid conditions is the blowing snow in western and southern parts of Minnesota. Sustained winds of 20 mph with gusts up to 35 mph will whip around the the powdery snow that fell Sunday and could reduced visibility on the roads. With that, a winter weather advisory has been issued.
