Rainfall and thunderstorms were the main stories of the month. As there were many convective events, rainfall amounts in the city varied greatly from place to place. Higher amounts fell in northern and western parts of the city with as much as 125 mm. The lowest amounts fell in southern and eastern areas, with as little as 85 mm. Those parts of the city missed out on some big rains on May 18th and 28th, which both dumped 20 to 30 mm of rainfall over western and northern parts of the city.
There was an abnormally high number of thunderstorm events in southern Manitoba this month. The most memorable thunderstorm events in the Winnipeg area were on the 14th, 18th, 23rd and 27th.
Storms on the 14th, along with a cold front, produced severe winds throughout southern Manitoba. These winds along with dry soil conditions created a dust storm over southern Manitoba. Dust storms are generally rare in southern Manitoba, however they do occur from time to time. This particular dust storm was different though. Fierce wind gusts as high as 90 to 100 km/h, along with flying dust and debris created near zero visibility in some areas outside of Winnipeg, making it the worst dust storm in recent memory.
Yet more storms rumbled through the city near midnight May 23. This particular storm will be known for its magnificient display of lightning. Lightning was flashing almost constantly at times, and there were many cloud-to-ground strokes.
Overall, a very active May...
