For a while it as looking like the summer of 2002 was going to finish early as a cool unsettled weather pattern took hold over the Prairies for the first half of August. Below normal temperatures and frequent shower activity were prevalent during the first 17 days of the month climaxing with a strong storm system on the 16-17th that brought heavy rain, gusty north winds and cool temperatures to southern Manitoba. The weather pattern then shifted to a more normal summerlike pattern for the latter half of the month with more sunshine, warmer temperatures and less frequent rainfall. Of the first 19 days of the month, only 6 days managed to reach 25.0C or greater, while 10 of the last 12 days exceeded 25C including the only two 30 degree days of the month. Overall, August 2002 ended up virtually normal temperaturewise at my site as well as wetter than normal (by about 33%) Number of days with measureable precipitation was 17 at my site, the most for any calendar month so far this year. The month ended on a humid note with the last 4 days of the month having dewpoints near 20C. Severe thunderstorms on the afternoon of the 23rd brought strong winds and marble size hail to the southern and eastern suburbs of Winnipeg, just outside Charleswood. As in July, the month ended with some vivid thunderstorms over southern Manitoba on the 31st, with heavy rain and frequent lightning in areas south of Winnipeg.
