Slick conditions developing Friday with mixed precipitation changing to snow and blowing snow Friday evening
A storm system over the western Prairies is forecast to track through the MB interlake region overnight into Friday bringing a mixed bag of weather over southern MB Friday into Friday night. Milder air in advance of the system will bring some patchy rain, ice pellets or freezing rain over southern MB Friday morning, with slippery conditions likely as rain freezes on contact with colder surfaces. Temperatures are expected to rise above freezing for a few hours Friday afternoon (+1 to +4C range) which will result in some melting of snow and ice. A strong cold front however is expected to push through the Red River valley by late Friday afternoon with snow and blowing snow developing accompanied by strong northerly winds of 50 to 70 km/h. This front will drop temperatures well below freezing Friday evening freezing up any standing meltwater resulting in slick conditions. Snow and blowing snow will bring about 5 cm of fresh snow to Winnipeg and the RRV Friday night with heavier amounts likely north and east of the city. Be prepared for poor driving conditions across southern MB and the Interlake regions especially Friday evening into Friday night as temperatures drop and snow and blowing snow produce poor visibilities. Environment Canada has issued a special weather statement for Winnipeg and southern MB on the potentially wild and wintery weather Friday.
