Historic blizzard ahead; Manitoba impacts discussed


TIMMING: WED NIGHT INTO THURSDAY


“50 to 60 mph wind gusts are expected Wednesday night into Thursday. On top of the heavy amounts of snow expected, this could be a potentially historic blizzard. Make plans now for Wednesday afternoon through Thursday.” -NWS Grand Forks, ND




ABOVE: Low depiction and main precipitation axis on Thursday morning. Southeastern parts of Manitoba is depicted to be in the accumulation area.


There is a sharp line between little precipitation and a lot of precipitation and that line is what is hard to forecast for. Right now, we are thinking anything southeast of Steinbach, MB could see between 15-25cm of snow or even less depending on Low track. Winnipeg should see trace amounts on Thursday.


HIGHWAY CLOSURES


I-29 in North Dakota: HIGHLY LIKELY

Hwy 75 in Manitoba: LIKELY AT PEMBINA

This system will bring a combination of rain, mixed precipitation, and snow to the region. The greatest snowfall amounts, 6 to 12 inches and possibly greater, are expected along a Valley City to Grand Forks to Thief River Falls corridor. More liquid precipitation, 1 to 2 inches, is expected across the far southern Red River Valley into adjacent areas of west central Minnesota. However, those areas could also get a few inches of snowfall as well.” -NWS Grand Forks, ND
