Good afternoon, everyone! Much-awaited warm air has finally moved into the Eastern United States, on the heels of a prolonged period of cold. Temperatures today are running well above normal across a widespread area. Meanwhile, a deep trough and associated disturbance moving through the Rockies will eject northward into the Plains States later tonight into Monday, leading to the potential for a significant snowstorm in the Northern Plains.
The National Weather Service in Minneapolis, MN is forecasting a significant snowfall – but the gradient in snowfall totals is expected to be quite sharp. Snowfall totals could be very high underneath areas where impressive banding occurs, but could be much lower outside of those heavy snow bands. A very tough forecast! We explain a bit in our video below. Meanwhile, warm air will surge into the Eastern United States on Monday ahead of the system.
