EMO Weather Outlook (Example)
Significant Weather Discussion for Ontario Provincial Emergency Operations Centre provided by Environment Canada’s Ontario Storm Prediction Centre issued at 5:00 AM EST Friday 20 January 2012. Discussion valid for today, tonight and Saturday with an outlook for Sunday.
Today… Cold Arctic air will generate flurries and localized snow squalls to the east of Lake Superior, affecting Hwy 17. A snow squall watch will likely be upgraded to a warning as the squalls intensify later this morning. Snowfall amounts up to 15 centimetres are possible. Otherwise no significant weather is expected.
Tonight... Flurries and squalls east of Lake Superior will gradually weaken and shift south. An area of snow from a passing disturbance south of the Great Lakes will give upwards of 5 cm across southwestern Ontario (grazing the GTA). There is high confidence in this event.
Saturday… No significant weather is expected.
Outlook for Sunday... A more significant disturbance will head towards the upper Great Lakes with 10 to 15 centimetres of snow possible around Lake Superior and northeast toward Hearst and Timmins.
