THUNDER BAY – WEATHER – There are weather alerts in effect for the City of Thunder Bay, Superior West, Nipigon, Rossport, and west into Atikokan, Quetico and along Highway 17 into Marathon and Beardmore.
Rain, heavy at times, is expected to begin Wednesday night and continuing into Thursday morning. Total rainfall amounts of 20 to 40 mm are possible by the time rain changes to snow on Thursday morning. Areas near Lake Superior could get higher amounts due to south/southeast winds off of the lake. Strong wind gusts of 70 to 80 km/h are also possible especially on Thursday afternoon.
The event is due to a low pressure system that is expected to track through the Midwest into the Upper Great Lakes by Wednesday. There is still uncertainty into the location and intensity of the system. Appropriate warnings may be issued if the situation warrants.
From the NOAA in the US, for Minnesota and the eastern side of Lake Superior, “In addition to all the other concerns with the approaching storm system tomorrow evening we are tacking on another one. With temperatures quickly plummeting on the backside of the system there is growing concern of a Flash Freeze. The rapid decrease in temperatures combined with the liquid presence of water at the surface may lead to black ice.
“Additionally, strong westerly winds will also be present during the morning commute. Be sure to allow extra travel time if commuting Thursday morning and leave plenty of distance between you and other vehicles”.
