System to bring rain and snow to southern MB Wednesday
A low pressure system moving across southern MB Wednesday into Wednesday night is forecast to bring an area of rain and snow to our area, with some potentially heavy snowfall through the Riding Mountain and Interlake regions where snowfall warnings have been issued. Current indications are that areas along and south of the TransCanada will get some rain and wet snow Wednesday while areas north of the TransCanada through the Interlake and Riding Mtn areas will see mainly snow.. possibly heavy at times. At this point, it looks like maybe 5 mm of rain will fall along the TransCanada corridor Wednesday, including Winnipeg, with rain mixed with wet snow at times especially by evening. Heavier snowfall amounts of 10-15 cm are possible to our north and northwest Wednesday into Wednesday night. Snowfall amounts will be tricky depending on surface temperatures (will be some melting with near or above freezing temps Wednesday), timing of transition to snow, and elevation issues (heaviest snowfall will likely be over higher elevations to the west of Lake Manitoba). Travellers should be advised that locally heavy snow may be occurring Wednesday into Wednesday evening, especially north and northwest of Winnipeg.
