Freezing drizzle leaves icy conditions in Winnipeg/southern MB...
Freezing drizzle was observed across Winnipeg and much of southern MB today as a moist mild airmass brought extensive low cloud and misty conditions across a large part of the Northern plains and eastern Prairies. The image here is what the Bishop Grandin webcam looked like this evening in the south part of Winnipeg, a result of a coating of freezing drizzle on the webcam lens. Kind of pretty actually.. looks like an impressionist oil painting! Freezing drizzle can sometimes occur in moist stagnant airmasses in the winter when temperatures are close to but below freezing, although it's not as serious as freezing rain which can lead to greater ice accumulations in a shorter time. However, an extended period of freezing drizzle can leave a thin coating of ice on exposed surfaces, with slippery conditions on untreated roads and walkways. Drier and colder conditions are expected overnight into Thursday as brisk northwest winds usher in a colder airmass from the north. Temperatures will return to normal over the next couple of days before another warmup this weekend. Some light flurries are possible from time to time, but overall no significant snowfall is expected over the next week as the snow drought continues over southern MB.
