A phrase that was used frequently in January has come back in February.
Environment Canada issued extreme cold warnings to areas of northern, central and eastern Saskatchewan on Tuesday night.
The weather office says a cold, arctic airmass is spreading southward bringing extreme wind chill values with it.
As cloud clears behind a strong cold front this evening, temperatures will drop rapidly and northerly winds will increase with gusts up to 60 km/h possible. These plunging temperatures and gusty winds will give wind chill values of -40 to -45 overnight and into Wednesday morning.
These extreme cold values will moderate early Wednesday afternoon.
