Short-Term Forecast
Current indications reveal that the mean temperature for the next 10 days will be below normal. Environment Canada’s mean temp anomaly shows that Southern Ontario will be around 0.5 to 0.8 deg. C below normal while the National Weather Service in the US puts a 70% probability of being below normal.
The continental map below courtesy of the National Centers for Environmental Prediction and the Center for Ocean-Land-Atmosphere Studies predicts that areas west of Quebec with the exception of the territories will experience below seasonal temperatures.
Southern Ontario will also experience bouts of rain resulting in cloud cover and temperatures in the low to mid teens. Current weather models don’t show a lot of convection from these systems but I’m watching for the one that’s expected to arrive early next week. Although it’s still too early for actual rainfall amounts but winds will be strong from the east gusting to 50 km/h and SLP of around 990 mb.
