Half of the weather map of Manitoba is covered in red yet again Tuesday morning.

Environment Canada has issued an extreme cold warning for all of southern Manitoba as an Arctic ridge of high pressure lingers over the province.

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

Some moderation will occur this afternoon, but some regions may experience extreme cold again tonight into Wednesday morning.

Winnipeg is expected to reach a high of -24 Tuesday, with a windchill around -32 in the afternoon.

Temperatures should arrive at more seasonal daytime highs by the latter half of the week, with a high of -15 on Thursday, and might even reach -7 by Saturday.

Environment Canada says frostbite is possible on exposed skin within minutes while windchill values are around -30 and below.
