Alberta Clipper heads to Manitoba
Portage la Prairie is currently under an active weather warning. Environment Canada supplied
Environment Canada is cautioning of a strong Alberta Clipper, centred over western Saskatchewan this afternoon, that will intensify and rapidly track southeastward into northwest Minnesota by Thursday morning.
Precipitation is forecast to spread across most of southern Manitoba this evening. Milder air ahead of this system will allow for mostly rain tonight with 10-20 mm possible. As this system tracks through southern Manitoba, colder air will wrap in behind this system and change the precipitation over to wet snow over western Manitoba overnight and southeastern Manitoba Thursday morning.
According to the special weather alert, heavy, wet snow can be expected over most of southern Manitoba on Thursday with varying amounts of accumulations. Highest amounts will be over southeastern Manitoba as this system slows down over Minnesota. With the ground still relatively warm, some of this snowfall will melt on contact.
In addition to the wet snow, strong northerly winds gusting between 80-90 km/h can be expected on Thursday with the highest gusts over the western Red River valley and in along the shores of Lake Manitoba. These strong winds combined with the falling snow will create reduced visibilities in blowing snow over open areas.
A weather warning is issued to cover the combination of these various significant weather impacts and the fact that this will be the first significant snowfall of the season.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to firstname.lastname@example.org or tweet reports using #MBStorm.
