Winter Weather Tracking to Northern Ontario
THUNDER BAY – WEATHER – Winter weather will hit much of Northwestern Ontario on Sunday. Environment Canada has issued a special weather statement for much of the region.
A low pressure system from Colorado is expected to track towards the Great Lakes today then rapidly intensify as it heads towards Lake Superior later on Sunday. The weather system should eventually move into Quebec late in the day on Monday.
Over most of Northeastern Ontario, current indications suggest that a few rounds of rain are likely tonight and Sunday then lasting into Sunday night along with well above normal temperatures. The rainfall could be heavy at times giving amounts of 25 to 50 mm. Rainfall warnings have been issued for the Sault Ste Marie to Sudbury corridor where 50 mm of rain is most likely.
Temperatures will rapidly fall early Monday as strong and gusty winds with much colder air move into the region with rain changing to snow. However, snowfall accumulations are not expected to be significant.
Farther to the west, in a swath of regions from north of Lake Superior to the Kenora area, temperatures will likely be cold enough that a significant snowfall is possible later Sunday into Monday.
Snowfall amounts will be highly variable and range from 2 to 15 cm.
A snowfall warning has been issued for the Sioux Lookout to Armstrong area where 15 cm of snow is likely.
