A strong upper-level wave and jet entrance region pushed into the Northern Plains, with a tight mid-level frontal boundary stalling across the area for several hours within confluent southwest flow aloft. Unseasonably cold air rushed into the region behind a southward surging low-level frontal boundary, with developing precipitation making a very rapid transition from rain to snow. Snow accumulated quickly in the overnight and early morning hours due to proximity of slightly unstable air aloft.
