A bitterly cold arctic air mass continues to have its grip locked firmly on Manitoba and northwestern Ontario on Monday.
All but the most northern regions of Manitoba remain under an extreme cold warning issued by Environment and Climate Change Canada (ECCC), including Winnipeg.
All of northwestern Ontario is also under the warning.
Daytime highs across all regions under the warning in both provinces will only reach the mid to upper -20s on Monday afternoon, with wind chill values from -40 to -50.
The trade-off under such strong arctic high pressure bearing down is plenty of sunshine.
Conditions will be even colder on Monday night. Overnight lows will drop to the low to mid -30s across most of Manitoba and northwestern Ontario. Wind chill values will remain dangerously cold. Frostbite can happen in minutes in these conditions.
However, overnight lows will rise overnight across northwestern Manitoba, signalling the start of some much-needed relief from the dangerous cold.
A relatively weak low pressure system will bring snow overnight across the region before spreading into the southwest on Tuesday morning and into Winnipeg and the southeast in the afternoon.
Daytime highs on Tuesday will moderate across the south, reaching the mid-minus teens.
Similar daytime highs are expected in Winnipeg on Wednesday and Thursday with a mix of sun and cloud, before much milder temperatures and possible flurries on Friday.
