An extreme cold warning is in effect for Estevan and the surrounding areas as a mass of arctic air moves into the region.
High winds are accompanying the systems, with gusts of 40 to 60 km/h expected throughout the day Monday, eventually subsiding overnight. The winds will usher in colder temperatures, with temperature steadily dropping during the day.
“When that arctic ridge comes down tonight, we’re looking at low temperatures in around -30° or -31° in southeastern Saskatchewan, so combined with a little bit of wind, that will bring the wind chill values up to around -41 or -42 by tomorrow morning,” explained Mark Melsness, a meteorologist with Environment Canada.
Behind the arctic air mass, there will be a warm-up of sorts. Melsness said the daytime highs will be closer to normal for Thursday and Friday, with the trend continuing into the weekend.
The mass of cold air is coming through on the heels of a system which brought snow and high winds to much of the province Sunday. Weyburn received around a centimetre of snow, but it was blown around by the winds.
The weather was also cited as a factor in a multiple vehicle pile-up near Lumsden Sunday.
