A strengthening storm system located over the central US, is forecast to move into the Great Lakes on Monday. A warm front ahead of the storm, will produce rain in southern Ontario and Quebec over the next 24 to 36 hours. Amounts may exceed 50mm (2 inches), especially where thunderstorms occur. There may even be some wet snow in the upper elevations of southern Quebec, New York and Vermont and the backside of the storm late Monday.
This storm had been powerful and deadly. Strong thunderstorms and long lasting tornadoes occurred in Texas and Oklahoma on Saturday evening. In Canton, Texas, five fatalities and multiple injuries were reported from a large and violent wedge tornado. Widespread damage was reported across central and northeast Texas. Lightning from the severe storms also sparked several house fires. Elsewhere, torrential rain has produced major flooding in Missouri and Arkansas, northward into Illinois. On the backside of the storm, unseasonably cold air is producing a narrow band of heavy wet snow and near blizzard conditions. The snow stretched from Colorado, including metro Denver where nearly 8 inches fell, northeast across western Kansas. Snow is forecast into the Dakotas, Minnesota, southern Manitoba and northwest Ontario today into Monday. The late season heavy snow has toppled trees and power lines.
