Wider weather episode

Low pressure passing to the north of northeastern Minnesota created conditions favorable for snow squalls. Gusty northwest winds and convective snow showers developed during the afternoon hours and affected portions of the Arrowhead of Minnesota, primarily in Cook and Lake counties. Visibility from webcams in the area was less than 1/4 mile at times in the heaviest snow squalls. Satellite and radar imagery revealed the convective nature of the snow showers and increased confidence that the squalls would persist for several hours.
