Prairies snow tonight through early Friday
Latest trends suggest that the storm moving out of the Rockies into the Prairies tonight through Thursday night will be a little farther north and a touch weaker than what we thought yesterday so I tweaked the snow accumulation map a bit.
Looks like the steadiest snow does go north of Winnipeg, but there could be a several-hour period of accumulating snow sometime Thursday or Thursday night.
A coastal storm will get drawn northward into Atlantic Canada Saturday night and early Sunday. The storm will primarily be a rain maker, but it will also produce some strong southeast winds across southern Newfoundland during the early morning hours of Sunday with some gusts over 85 km/h.
The rain may briefly change to wet snow before ending Sunday over northwestern Nova Scotia and eastern New Brunswick, but right now I do not expect any accumulation.
No changes to my thinking from yesterday in regards to the short lake-effect snow event coming in Friday night through the first half of Saturday. I will post accumulation maps perhaps tomorrow or certainly Friday.
There is the potential for a fairly significant, moisture-laden storm to track up through the interior eastern U.S. on Tuesday. Computer models have trended much farther west with the track, which would potentially put large parts of Ontario and Quebec in the path of accumulating snow with rain farther south and east.
Right now, it looks like the main impacts of this storm will be later Tuesday, Tuesday night into early Wednesday. Behind this storm it looks like another favorable set-up for widespread lake-effect snow later Wednesday into Thursday next week. I will keep you posted.
