First Winter Storm of season
A strong Arctic cold front will blast the western Great Lakes this week with big changes in store for all of Ontario. The front will spawn a low pressure area over the upper part of Michigan that will become a potent fall storm. It is an early "November Witch". The storm will become intense with howling winds and heavy precipitation.

So far a Winter Storm Warning is in effect for parts of Northwest Ontario with Winter Storm Watches for the U.P. of Michigan and northern Minnesota and Wisconsin. Heavy lake effect snows are expected with close to 10 inches possible. Winds will howl over 40mph.

Windy wet weather will affect Eastern Ontario into Thursday with a cold rain and gale force winds. Over 25mm of rain will fall with dropping temperatures.
