August 19 to September 22, 2012
Warm weather is likely to prolong summer-like temperatures across most of Eastern Canada well into September. The upper-level ridge responsible for the warmth is expected to suppress rainfall to below normal in many of these regions from Ontario to the Maritimes. However, occasional storms in late August and September may bring a few heavier rainfall events to the eastern Atlantic provinces. Elsewhere, cooler outbreaks in Western Canada will result in the first frost of the season in many areas. As a result, temperatures are likely to average close to longtime normal values from northwestern Ontario westward through the Prairies and into eastern British Columbia. Precipitation in these areas is expected to run near or a bit below normal. Farther west in coastal British Columbia, look for a continued cool circulation off the Pacific with several wet spells showing up in September.
