THUNDER BAY – It would be nice if this update were an April Fool’s gag. However Environment Canada has issued a special weather statement for the region. A low pressure system approaching Southern Lake Michigan will track into Northeastern Ontario by this evening. This low pressure system will bring a significant late season snowfall with it to all regions northwest of its track.
A total snowfall of 10 to 15 cm is expected by later this morning over Northwestern Ontario near the Minnesota border and Lake Superior with slightly lesser amounts further north. The wet snow will spread into Northeastern Ontario early this morning as temperatures drop. Amounts near 10 cm are possible in those regions north of the track of the low. Wet snow may be mixed at times with rain especially during daytime hours when temperatures may hover just above the freezing mark.
Areas near and southeast of a line from Sault Ste Marie to Kirkland Lake will receive lesser amounts of wet snow as milder air moves in resulting in a changeover to rain midday. Two to five centimetres of wet snow are anticipated before the changeover to rain.
Latest indications suggest that a snowfall warning will not be required as the condition of receiving 15 or more centimetres of snow within a 12 hour period will likely not be met.
Considerable uncertainty exists regarding the exact track of this low and associated snowfall amounts, thus it is recommended that people in the regions monitor local forecasts as well as this statement for additional updates.
Motorists should be prepared for winter driving conditions as visibility in areas of heavier snow may be quite low. Accumulating snow on untreated roads will also contribute to hazardous winter driving conditions.
