The month started angrily with two significant thunderstorm events on August 1 and August 3. These would end up being the only major thunderstorms of the month however.
More torrential rains fell the next morning on August 4, dumping an aditional 10 to 15 mm.
August 24: A moderately-interesting thunderstorm event for parts of southern Manitoba. Lightning was frequent around Winnipeg late in the evening. The storm produced brief torrential downpours in south and east parts of the city with 2-4 mm reported there.
After a warm and stormy start, things were much cooler mid-month as daytime highs were in the low to mid twenties and overnight lows in the mid to high single digits. To many, it was probably a welcomed break from the heat. In fact, up to the 22nd temperatures were actually averaging below normal for the month. We had even seen our first lake-effect rainfall event of the season on Aug 15-16.
Things returned to mid-summer heat late month as we experienced 6 days of 30°C+ weather. August 29 was a highlight as very hot temperatures moved in from south of the border. Temperatures were in the mid to high thirties throughout southern Manitoba, resulting in many records being broken. Dauphin was the hot spot at 37.9°C. Winnipeg reached 35.4°C; not breaking a record, but tying for hottest day of the year. To make things worse, it was humid on top of the heat for the RRV as humidex values were in the low forties. As of Sept 1, we have now had 21 days of 30°C+ heat in Winnipeg this year.
The higher rainfall amounts this month in southern Manitoba along with cooler weather mid-month aided farmers. It is predicted to be a bumper-crop year, at the same time that prices are quite high due to drought in the US and eastern Canada. It could be a very good year for Manitoba farmers.
