Long Range weather - Canadian Thanksgiving
Hello!.. I have been seeing others' requests for long-range weather forecasts and wondered if it would also be possible to find out more for the Orangeville area over the Canadian Thanksgiving weekend? - October 11-14, 2019. Thank you so much!
Summer 2019
Summer 2019 definitely hasn't been cool and rainy as predicted for Southwestern Ontario. It's been very hot and humid with drought conditions, which can always be expected for that area.
Not sure where you are
Not sure where you are located but we have only had to water our vegetable garden a few times this year because of so much rain. No drought like problems just north of london Ontario. If anything it was too much water which caused havoc in the garden.
Precipitation
I live in Brant County, which is probably the driest area in all of Ontario. We have had very little rain since May. The grass was looking very yellow by early August. It"s better now though due to overnight moisture this time of year Most systems go around us or dissipate as they near due to the lower land elevation and not being too close to any of the Great Lakes. And it's the same during the winter; very little snow falls here. It's prone to drought year-round. We did have a very unusual rainy period from late January to May this year. It was very much needed though due to years of drought. And as a result, the vegetation and wildlife are very healthy and abundant this year; and their health is what's most important. So we are grateful when it rains.
2019 observation
We have noticed that there are no pine cones on the pine trees in our cottage property near Georgian Bay. Could you advise as to what this might mean for squirrels and such this winter. What is Mother Nature telling us?
pine cones
Our Mother is saying that it won't be a cold summer!
Pine Cones
It means that it won't be a cold winter****** haha
