Alerts for: Geraldton - Manitouwadge - Hornepayne


4:06 PM EDT Wednesday 23 April 2014
Special weather statement in effect for:

  • Geraldton - Longlac - Caramat

Significant snowfall possible beginning late Thursday.

A low pressure system developing to the Lee of the Rockies will slowly track towards the Great Lakes over the next few days. An area of precipitation associated with the system is forecast to spread into Northwestern Ontario Thursday.

There is still significant uncertainty regarding the low track and how much snow or rain is expected since temperatures are forecast to be near or just above the freezing mark. However, latest guidance suggests that precipitation will begin as wet snow or rain and then change to all snow late Thursday west of Lake Superior and Thursday night north of Lake Superior. If temperatures are sufficiently cold, total snowfall amounts could be in the 10 to 20 cm range by the time the snow comes to an end Friday night. The highest amounts are expected near the Lake Superior shore where snow could be heavy at times and may approach or exceed Environment Canada's warning criterion of 15 cm within 12 hours.

Meteorologists continue to watch the development of this system closely.
