Forecast Discussion

Heavy fog is possible throughout parts of Southwestern Ontario including Windsor, Sarnia, London and K/W during the early morning on Saturday. This may reduce visibility on the roads to near-zero before sunrise so be sure to travel with caution. As usual, the fog will burn off quickly after sunrise. Heavy rain is also expected during the day on Saturday with the heaviest rainfall accumulation around Lake Huron and Georgian Bay. Although with the highest rainfall totals topping out at around 10-15mm, it won’t come close to the 25mm threshold to include on the outlook map.
