Environment Canada's forecast low for Winnipeg of -30 C seemed quite reasonable.<BR/><BR/>Saskatoon and Edmonton which were under the arctic high on Thursday morning went down to -35 C. Taking into account some moderation as the high dropped southeast it is surprising that Winnipeg managed to actually get colder dropping to -37C!<BR/><BR/>Infact the ridge had not completely built into Winnipeg with decent winds to keep things from bottoming out completely.<BR/><BR/>850 mb temps were not that cold (-22 C)... the same as yesterday ... and there was a southwest flow aloft above 700 mb. Must have been a very shallow layer of cold air that snuck into the interlake and down to atleast Winnipeg airport.<BR/><BR/>By tomorrow morning the ridge should be from southern North Dakota to to the north shore of Lake Superior but forecast lows are no colder than -29 C even in traditional cold spots of northern minnesota. Air mass modification that we never benefited from? ... Or is the guidance underestimating the shallow layer of cold air<BR/><BR/>DanAnonymousnoreply@blogger.com
