Updated Weekly Long Range Forecast

August 27, 2013; 9:21 AM ET

Before I get to the long range, clusters of heavier rain and strong thunderstorms will mainly impact southwestern Ontario into the early afternoon today, especially from Sarnia on south as storms track southeastward into Ohio.


Long range update

Instead of just interpreting the latest ECMWF long range model like I have been doing for quite some time now I will also be taking into account several other factors (other models, natural oscillations, current observations and my own experience) when it comes to drawing up these maps. By doing this I hope to further increase the accuracy of these long range maps as we head into winter.
