St. John Valley weather for Jan. 19-25, 2022

Three-day outlook: Wednesday-Friday

The arctic air mass that settled yesterday will move east of the region today while an Alberta clipper approaches from the Great Lakes with snow likely in the afternoon tapering to snow showers this evening that linger overnight into tomorrow morning. The system is not moisture rich, and snowfall is expected to be around one inch with less than one inch overnight.
