Enjoy those mild temperatures early this morning.. because they will soon be history as a sharp Arctic cold front drops southward across southern Mb this morning, ushering much cooler air from the north. As of 9 am the front has pushed through Winnipeg with northerly winds and temperatures steady near 15C (17C in Charleswoood) However just to our north, it was down to 12c in Selkirk and 8C in Gimli, with even colder readings of +4c through the interlake. This surge of colder air is pushing south faster than predicted, so that forecast high of 26C for Winnipeg is not likely to happen.. instead look for temperatures to remain steady or fall through the day. (Update: forecast for Winnipeg just amended down to a high of 18C)
This cold airmass will be fully entrenched over southern MB by tonight just in time for the long holiday weekend. Dress warmly if you're camping this weekend as daytime highs will only be in the low teens, and nighttime lows just above freezing. Showers are likely by holiday Monday.
