Original story:

If you are heading south today or tomorrow, be aware that Environment Canada is advising that snow squalls and poor driving conditions are occurring as you approach the Sundridge-Burks Falls area and down past Barrie. 

Conditions are favourable for lake effect snow squalls from Georgian Bay to develop today and continue through the day Friday.

Local snowfall amounts near 15 cm are possible in the heaviest snow squalls.

Travel may be hazardous due to sudden changes in the weather. Visibility may be suddenly reduced at times in heavy snow.

North Bay will see scattered snow flurries today, but snowsqualls tomorrow with an accumulation of 5-10 cm.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
