Bitterly cold temperatures and a bit of wind mean another wind chill warning for virtually all of southern Manitoba.

Meanwhile, a blizzard warning covers the extreme northeast of the province, including Churchill.

In the south, extreme wind chills of –40 are being felt from Brandon to Beausejour, from Gimli to the international border, and everything in between, including Winnipeg.

An Arctic ridge of high pressure hanging over the Dakotas is creating winds of 15-20 km/h, which are making already-cold temperatures feel much worse.

At these extreme wind chill values, frostbite on exposed skin can occur in less than 10 minutes, so bundle up.

The wind chills are expected to moderate late in the morning as temperatures rise, although gusty south winds will continue to produce cold conditions, according to Environment Canada.

Temperatures at 7 a.m. ranged from –30 C to –34 C.

In Winnipeg, the mercury is expected to rise to –15 C by Thursday afternoon and continue to warm up Thursday night into Friday morning — all the way to –3 C by Friday afternoon, according to CBC meteorologist John Sauder.

Intense system

As for the far north, an intense low pressure system is moving across southern Nunavut.

In advance of the system, two to four centimetres of snow is expected to fall across northern Manitoba by the evening.

As the system tracks into Hudson Bay tonight, very strong northwest winds will develop along the coast causing widespread blizzard conditions with zero or near-zero visibility, according to Environment Canada.​

The blizzard is expected to begin in Churchill near midnight with winds hitting 60 or 70 km/h.

The blizzard will continue through Friday with northwest winds gusting to 90 km/h at times and zero visibility.

Things should improve Saturday morning but blizzard conditions could redevelop again on Sunday as the low lingers in Hudson Bay and another ridge strengthens in the western Arctic, Environment Canada said.
