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.
