A Colorado Low exited the eastern slope of the Rockies and moved towards the Great Lakes producing snow across the region. Several key ingredients were expected to come together with this system including favorable moisture within the snow growth zone and strong signals for frontogenesis leading to enhanced lift. Models struggled with the track of this system and, while snow was expected across the region, the heaviest snow ended up setting up across northwest Wisconsin as opposed to eastern Wisconsin. Very heavy snowfall rates were observed with a location in Burnett County receiving 7 inches of accumulation in about 3 hours. Snowfall totals of 6 to 10 inches were received with a high of 9.8 inches near Manitowish, Wisconsin.

The last two nights of the arctic outbreak were the most widespread in terms extreme wind chills. On the night of the 13th, a surface low over Lake Superior coupled with high pressure over the Northern Plains set up a gradient over the Northland, keeping winds in place through the night and into the morning of the 14th. The entirety of the Northland saw extreme wind chills and air temperatures in the 30s and 40s below zero. This was the eighth night of an arctic outbreak across the region that lasted over a week.

A weak short wave moving over West Texas and a dryline in eastern New Mexico were able to generate scattered thunderstorms on the afternoon of the 14th. These thunderstorms initially developed along the dryline and slowly moved east into the extreme southwestern Texas Panhandle. One of these thunderstorms became severe as it moved across Parmer County creating quarter size hail.

The last night of the arctic outbreak was once again widespread, affecting almost all of the Northland. High pressure was in place over the region leading to optimized radiational cooling conditions and the slightest breeze of wind was enough to send wind chills into dangerous criteria. Air temperatures dropped into the 30s and 40s below zero once again with wind chills as low as -44F. This was the ninth and final night of an arctic outbreak across the region that lasted over a week.

Severe drought conditions developed in late February across much of north central and parts of central South Dakota.  Precipitation departures since October 1st, 2020 had been from three-quarters of an inch to two and a quarter inches below normal or only 25 to 50 percent of normal.  Topsoil and subsoil moistures were anywhere 17 percent to 45 percent short or very short. The winter wheat was showing the affects from the dry conditions with 1 percent to 43 percent very poor to fair. Some winter pastures were looking overgrazed with some ranchers bringing in supplemental feed. Some dugouts and stock ponds were dry or contained poor water quality.  Finally, cured fuels and lack of snow cover led to increased fire danger which was unusual for this time of year. The grassland fire danger had reached high to very high several times during the latter part of February, with a few grass fires reported.

A massive arctic plunge into the Northern Plains brought almost a week of dangerous and life threatening wind chills to the region. The worst conditions were recorded between February 13 and February 16 when wind chills occasionally dropped as low as 35 below to 55 below zero. Numerous record low maximum and minimum temperatures were also established. The areal extent of the extreme cold in the central portions of the U.S. led to stress on the power grid, which necessitated several short-term rolling power outages impacting more than 10,000 customers during the peak of the cold.
