A storm system is expected to cross North Dakota Sunday bringing a widespread area of snow across the southern Prairies and northern Plain states. Current indications are that the heaviest snow with this system will affect areas mainly near and south of the international border Sunday, although snow is expected across much of southern Manitoba as well. Early snowfall estimates point to about 5 cm along the TransCanada corridor (including Winnipeg) with 10 cm closer to the US border and 10-20 cm south of the border. If the storm tracks further north, these amounts will increase northward. This system is still 3 days away, so there continues to be some uncertainty on its exact track and associated snowfall, but it certainly bears watching, especially if you're considering travel Sunday across southern MB or the northern US states. Stay tuned.
UPDATE: Sat Feb 25th: Winter storm warnings are now in effect for northern ND and MN, and southern SK up to the Manitoba borders. Looks like worst of storm will be tracking from central Alberta through southern Saskatchewan into North Dakota where snowfalls of 10-20 cm are forecast, with southern MB on the northern edge of the heaviest snow (up to 10 cm possible near the US border - see accompanying map showing 24 hr snowfall amounts between noon today and noon Sunday). Note that over southern SK today, strong easterly winds and snow will combine to produce possible blizzard conditions at times today, including over the TransCanada from the AB border to Regina area. If you have travel plans out west today or south tomorrow, be prepared for poor highway conditions and possible road closures.
