Western Canada saw a sharply uneven precipitation pattern over the 30 days ending Wednesday, with the driest conditions concentrated across Saskatchewan and parts of southern Alberta and Manitoba.
As can be seen on the map below, large portions of southern and central Saskatchewan received less than 40% of normal precipitation during the period, with another broad area receiving just 40% to 60%. Much of southern Manitoba was also drier than normal, although some pockets received above-average rainfall. Alberta precipitation was variable.
The pattern reflects a growing season finish that has been considerably drier across parts of the Prairies, particularly Saskatchewan, following wetter conditions earlier in the summer. In Saskatchewan, the lack of late-season rainfall likely accelerated crop maturation and helped fields dry down as harvest approached, although it may also have limited final yield potential for later-developing crops in the driest areas.
In Alberta, comparatively better moisture in some northern areas has supported crop development, while drier conditions farther south have favoured maturation and harvest activity. Manitoba has seen more mixed conditions, with localized heavy rainfall contrasting with increasingly dry areas elsewhere.
