yellow watch - snow squall - in effect Lake effect snow off Lake Huron and Georgian Bay expected Friday. What: Local snowfall amounts of 10 to 20 cm. Reduced visibility in heavy snow and blowing snow. When: Friday morning through Friday night. Additional information: Lake effect snow off Lake Huron and Georgian Bay will quickly develop Friday morning as temperatures rapidly drop in the wake of a strong cold front. Westerly to northwesterly winds gusting 60 to 80 km/h will result in blowing snow. The combination of heavy snow and blowing snow may result in near zero visibility at times. As the winds will shift from westerly to northwesterly through the day, lake effect snow bands are not expected to persist over a given location for a prolonged period. As a result, reduced visibility in heavy snow and blowing snow will be the primary hazard as opposed to snowfall accumulations. Lake effect snow should weaken through Friday night. ### Travel may be hazardous. Visibility may be suddenly reduced to near zero at times.
