Winnipeg set a new record for the driest July since records began nearly 150 years ago in 1873. Rob Paola, a retired Environment Canada meteorologist who still follows weather and weather history in southern Manitoba, says the Winnipeg airport recorded 8.5 millimetres of rain this past July, when the 30-year average is 75.8 millimetres. That comes after a prolonged 21-month dry spell that has depleted groundwater sources and sucked the moisture out of the soil.
