Prairies Sees Rapid Harvest

A weather pattern featuring a ridge at upper levels has kept the Canadian Prairies with a mostly dry and mild to warm weather pattern so far during most of September. While the seemingly endless days of sun and warm weather are great for harvest, soil moisture levels are diminishing across the region. More rainfall would be helpful for winter wheat establishment and to replenish soil moisture reserves for the spring planting season.

Warm, dry weather conditions have allowed the spring wheat crop to finish up in most all areas during the past week while allowing many other crops to be swathed. Combining is advancing at a rapid pace throughout with the main problem being a couple of periods of strong winds recently. Reports from both Saskatchewan and Manitoba indicate that strong winds have blown around swathed crops and some shattering has been noted.

Frost has been noted at times but since the season has been advanced with harvest well underway the impact on crops has been minimal. The only area where some damage may have occurred was through the Interlake Region of Manitoba where frost impact is still being assessed. Frost is not unusual at this time of year for most areas.

The upcoming weather pattern will continue to favor drier and milder than normal conditions for the Canadian Prairies during the next week or so. Given these conditions it is expected that harvest progress will remain ahead of schedule. While favoring the remaining harvest the dry weather is a developing concern winter wheat which is being planted.

Considering that a weak El Nino appears to be underway it is possible that a milder and drier than normal weather pattern could continue into the winter season. El Nino tends to produce these conditions for western Canada, including the Prairies during the winter season.
