All of southern Manitoba is again waking up to extreme cold warnings Wednesday morning.

Environment Canada says an Arctic ridge of high pressure continues to give frigid temperatures to portions of the southern prairies.

Temperatures in the -30s along with winds of 10 to 15 km/h will produce extreme cold windchills of -40 or colder.

Some moderation will occur later this morning but these wind chill values could resume one last time over sections of the Interlake and/or eastern Manitoba tonight into Thursday morning.

Extreme cold puts everyone at risk. Risks are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter. Frostbite can develop within minutes on exposed skin, especially with windchill.

Winnipeg has a forecasted daytime high of -23 for Wednesday with a windchill of -30 in the afternoon, and an overnight low of -25 with a windchill of -33.

More seasonal temperatures are on the way with a high of -14 on Thursday, and milder temperatures of -6 and -7 on Saturday and Sunday respectively.
