THUNDER BAY -- The city's residents shouldn’t be expecting Monday’s warm weather to continue this week.
“It’s a one-day wonder really,” said Peter Kimbell, warning preparedness meteorologist with Environment Canada.
Sitting at about 5 C at 11:30 a.m., temperatures are supposed to reach 8 C by the afternoon.
But winds coming from the west will bring the normal colder weather back by Monday evening.
“The warm air is basically funneled up from southern Minnesota up over Northern Ontario,” Kimbell said, noting temperatures in southern Minnesota this morning were around 12 C.
But a low pressure system moving eastwards across the North during the day combined with winds up to 50 kilometres per hour will bring temperatures in Thunder Bay back down by 7 p.m.
Kimbell said Thunder Bay residents shouldn’t expect consistent weather this week either, saying it’s a bit of a yo-yo week.
Tuesday is looking to be to drop below zero and Wednesday’s high is expected to be 0 C.
“Thursday we get into a bit more warm air again so periods of rain are possible on Thursday with a high of plus five. Then back into the cold again for the weekend,” Kimbell said.
An average winter is expected over the next couple of months, but Kimbell said long-range forecasting is difficult to predict.
It's not a record high for this day. In 1962 the mercury hit 12.2 degrees.
