Snowfall warnings issued for western Manitoba


Warnings

3:35 PM CDT Tuesday 31 March 2020 Snowfall warning in effect for areas in red


Snowfall with total amounts of 10 to 20 cm is expected. A strengthening low pressure system will track northward out of the Dakotas on Wednesday, giving heavy wet snow to areas near the Saskatchewan Manitoba border. The snow will begin early in the morning in the south and work its way northward throughout the day. Current indications are that 10 to 20 cm will fall with this system, although local amounts could be higher. Some surrounding regions may also be added as the system moves in, depending on the track of the system. As you go east, amounts will be less as the precipitation will be lighter and transition to rain. Localized areas of freezing rain are also possible, however the main impact of this system will be snow. Prepare for quickly changing and deteriorating travel conditions. Snowfall warnings are issued when significant snowfall is expected. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to MBstorm@canada.ca or tweet reports using #MBStorm.



Wednesday April 1st, 2020

Our forecasted snowfall map issued Tuesday morning

Threat level: MODERATE TO HIGH

Confidence: MODERATE (based on model agreements)

Expected hazards: SNOW // BRIEF WHITEOUTS // TRAVEL IMPACTS // MIXED PRECIPITATION

Expected snowfall: 10-20cm

Locations impacted: western Manitoba

Expected watch: special weather statements and snowfall warnings

Most likely areas impacted: cities in western Manitoba (Souris, Melita, Brandon, Dauphin, Virden, Trans-Canada Highway from Portage La Prairie to Saskatchewan border and vicinity)

National Blend of Models for surface temperatures (in C) on Wednesday morning

Tuesday AM Discussion: downgraded the confidence level from MODERATE to HIGH to MODERATE only as current CAM's are having difficulty positioning the transition zone, the position of the lows and HRRR showing generally dryer solution (while NAM 3km showing heavy wet snow). General consensus remains that travel impacts are likely, especially along the Trans-Canada highway from Portage La Prairie to the Saskatchewan border (potential closures). Anything east of Portage La Prairie seems to remain above 0C in the warm sector and therefore should see all rain from this event. Current guidance still suggest this will be an impactful spring storm, especially across Westman. Expect snowfall warnings to be issued later today.
