Canadian Prairies Harvest Weather

Harvest progress across the Canadian Prairies continues to move along at a rapid pace. Weather has aided with warm temperatures and very little rainfall. A weather pattern that is featuring a jet stream that is further north than normal for this time of year has allowed most of the storms to stay to the north and has allowed a westerly flow of air which warms as it drops in elevation coming down from the Canadian Rockies.

Alberta, Saskatchewan, and Manitoba are all reporting crop progress to be ahead or well ahead of normal for this time of year. For the most part crops have either been harvested or swathed in most areas. Harvest progress is mostly more than 50% for all three provinces as of early this week with some crop harvest complete.

The lack of rainfall has been great for harvest but is leading to drying soil moisture for most areas. While soil moisture levels are being reported at close to 50 percent for adequate levels we have seen a steady decline during the past few weeks with many areas seeing little or no rainfall.

Winter wheat is starting to emerge in some areas and seeding continues in other areas but more rainfall will be needed to help with germination during the next few weeks before winter. Rainfall will also be welcome to help replenish soil moisture reserves and to help out with fall field work.

The weather outlook for the next 4 or 5 days will show more warm, dry weather allowing for harvest to continue at a rapid rate. There are some indications that temperatures could turn much cooler during the second half of next week but with precipitation at only sparse levels.
