Dry, hot weather in southwestern Ontario may have an impact on farmers' crops, cutting into profits this season. According to data collected by Environment Canada, after 9.2 mm of rain fell on June 20, only 6.1 mm fell from June 21 to July 4. During that span, three heat warnings were issued by the weather authority, with temperatures reaching the low to mid-thirties. Geoff Coulson, a warning preparedness meteorologist with Environment Canada, said the heat is "definitely more concentrated in extreme southwestern Ontario."
