A strong Alberta Clipper will bring more snow and wind to southern Manitoba over the next 24 hours. Snow has already begun pushing into southwestern Manitoba this afternoon and will continue to push east through the remainder of today.
Snow should reach the Winnipeg area by 5-7 pm and increase in intensity this evening. Snow should be mainly gone by early morning tomorrow, other than a few flurries. Note that the snow may be quite heavy at times with significantly reduced visibilities. At this point, it looks like most of southern Manitoba will have an opportunity for 5-15 cm. Here's my forecast snowfall totals for a few select locations from east to west:
Steinbach 8-13 cm
Winnipeg 8-13 cm
Portage 10-15 cm
Morden 8-13 cm
Brandon 10-15 cm
Dauphin 5-10 cm
Notice that higher confidence in higher totals has prompted me to raise my earlier forecast totals. Locally higher amounts are possible if an area is hit by more heavier bands. Areas along the escarpment and Riding Mountains also have an enhanced chance for the highest snowfall totals due to upsloping for part of the night.
Breezy easterly winds of 20-40 km/h will create drifting and local blowing snow on highways, especially late evening and overnight. Not a blizzard, but certainly not great for travel.
In addition, northerly winds of 30-40 km/h will create some local blowing snow on highways in the RRV tomorrow as well, not enough for blizzard conditions however. Inside city limits in Winnipeg, winds shouldn't be a major concern with this system.
