A quick moving storm system over northern Alberta will be dropping southeast into southern Manitoba overnight, bringing a wintery mix of precipitation to the area. Snow will be spreading into the Parklands and northern Interlake regions after midnight reaching Winnipeg and the Red River valley by 5 am Wednesday morning. Snow will likely be heavy at times through the morning rush hour in Winnipeg with 5 to 10 cm possible between 6 am and noon. That will have a significant impact on the morning commute due to snow covered roads and poor visibility so plan on taking extra time getting to work or school Wednesday morning.  Further west, snow will likely mix with or change to freezing rain over southwest Manitoba where freezing rain warnings are in effect.

For Winnipeg, snow will taper off by noon before things will get a lot slushier in the afternoon as our winds shift into the west tapping milder air from Saskatchewan. This will send temperatures above freezing in the Red River valley including Winnipeg with afternoon highs near +2C expected. That will mean a lot of slush and melting snow on the roads into the evening rush hour, so make sure you have plenty of washer fluid if you're out driving Wednesday.
