Snowfall Warning

City of Winnipeg

Issued at 10:53 Tuesday 15 December 2015
Colorado Low to bring 10-20 cm of snow on Wednesday. A developing Colorado Low will move northeastwards through the day today across the Central and Northern Plains of the United States and push into Minnesota through the overnight period. As this storm system approaches, it will spread snow into Southern Manitoba overnight into Wednesday morning. Moderate to heavy snow will build into the region between 6 and 9 AM, with significant accumulations nearing 10 cm likely by noon. Snow will continue falling through the afternoon, but likely be lighter than the morning. A further 4-8 cm are possible through the afternoon. Light snow will continue overnight with lesser accumulations. Through Wednesday evening, relatively brisk northwesterly winds will set up over the province which will combine with the fresh snow to produce localized areas of blowing snow which may cause abrupt visibility restrictions on area highways. It's important to note that the heaviest snow will be falling along a narrow band and will be sensitive to the exact track of the low pressure system. While there is high confidence in the current snowfall forecast, Environment Canada meteorologists will continuously track this developing system and adjust the warning areas if required. Be prepared to adjust your driving with changing road conditions. Prepare for quickly changing and deteriorating travel conditions. Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to storm@ec.gc.ca or tweet reports to #MBStorm. Find out more ›

Special Weather Statement

Colorado Low to bring snow and colder temperatures to Southern Manitoba. Environment Canada meteorologists are tracking a developing Colorado Low that is set to push through the Northern Plains of the United States. The development of this system will be somewhat dysfunctional. The main disturbance is forecast to track northeastward tonight, moving across Minnesota on Wednesday before reaching Northwestern Ontario on Thursday. As a result, initially the main swath of snow will lie east of Southern Manitoba. However a secondary area of heavy snow is expected to develop along a trough of low pressure protruding northward from this system. Snowfall associated with this feature will track into Southern Manitoba overnight and continue on Wednesday. Because of the complex development of this system numerical models have had some difficulty determining the intensity and placement of the snowfall. At this time models are suggesting that the heaviest snowfall will lie along a line extending northeastward from Pilot Mound through Winnipeg towards Bissett. Preliminary estimates suggest 10-15 cm of snow are possible along this axis by late Wednesday. Locally heavier amounts may be possible particularly along the Manitoba Escarpment. In the wake of this system brisk northwesterly winds will develop resulting in drifting and some blowing snow by late Wednesday. Colder temperatures will also enter the region with daytime highs remaining near seasonal values for the latter portion of the week. For mid December average daytime highs for Winnipeg and Brandon are near the -10 c. The public is advised to monitor public forecasts for any warnings that may be issued in advance of this system later today. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to storm@ec.gc.ca or tweet reports to #MBStorm. Find out more ›
