A warning preparedness meteorologist for the Meteorological Services of Canada says a dry fall for mid western Ontario can be attributed to some high pressure systems from the US midwest.
Geoff Coulson says not only has that high pressure made things milder than normal, it's also pushed back expected precipitation in the area.
"That's acted not only to give us milder than normal conditions over the last couple months, but it's also acted to deflect a lot of the significant weathers systems, keeping them up over the far north of Ontario, or keeping them much further south down through the mid-atlantic states in the US."
The Wiarton area saw the driest October since 2010, with many surrounding areas seeing unfamiliar, mild dry spells as well.
Coulson also mentions that some upcoming snow-fall will be a reminder of how November is supposed to be. While the upcoming snow likely won't stick around due to mild temperatures, the next few days will be a preview of regular winter weather.
"Sort of a mxture of rain shower and flurry activity for Saturday, that's going to change to flurry activity Saturday night and into Sunday. That could set up some potential bands of snow coming in from Lake Huron, so lake-effect snow for Sunday that could result in some local accumulations from 5-10 cm," he says.
October and early November have been quite mild beyond the norm, and Couslon says significant winter weather won't come untill likely mid-December.
