(Darren Bernhardt/CBC)A number of warm temperature records have been battered in pockets of Manitoba, most of them decades after they were set, but a warm spell at this time of year is not that rare and cold weather is forecast this week. Portage la Prairie ended the weekend as the country’s hottest spot, reaching almost 14 C on Sunday — the warmest temperature the city has recorded on Nov. 23 in 135 years, Environment Canada and Climate Change Canada says.Warm weather records were broken in 17 other communities in Manitoba on Sunday. The relatively balmy temperatures stemmed from a low-pressure system in Nunavut that kept colder air north, and warm air moved from the United States into Manitoba, said Natalie Hasell, a warning preparedness meteorologist at the federal weather agency. “It is something we see often, especially at this time of year in this transition period,” she said. “It’s not that unusual.”Once that weather system passes, temperatures are expected to fall below the freezing mark and closer to –10 C in southern Manitoba, Environment Canada said. The mercury rose to 10.3 C in Winnipeg on Sunday, setting a new milestone for the warmest Nov. 23 the city has seen in 153 years of weather records. (Trevor Brine/CBC)The mercury hit 10.3 C in Winnipeg on Sunday, setting a new milestone for the warmest Nov. 23 the city has seen in 153 years of weather records. The average high for this time of the year in Winnipeg hovers around -5 C, according to Environment Canada. Sunday’s temperature battered the record set for that day 83 years ago, when the heat soared to 8.9 C in 1942. Records for warm temperatures were also set in Berens River, Carman, Deerwood, Fisher Branch, Gimli, McCreary, Melita, Morden, Norway House, Oak Point, Pinawa, Pine Falls, Shoal Lake, Sprague, Steinbach and Winkler. Carman beat its 1942 record for Nov. 23 after the temperature rose to 13.3 C. Deerwood, McCreary, Melita, Morden, Sprague, Steinbach and Winkler also set new records with double-digit highs on Sunday.Most of the records for warm temperatures had been set more than 30 years ago, but the same parts of Manitoba have also experienced warmer than normal temperatures during the last days of November in recent years, Hasell said.Winnipeg, for example, recorded 7 C on Nov. 23, 2011 — even though that temperature didn’t set a new record, it was still high above seasonal. “You can’t say that we haven’t had very warm temperatures on the 23rd of November for the last several decades,” Hasell said.Most of Manitoba has recorded warmer than usual temperatures consistently since early September, Hasell said.Temperatures to dipWhile climate change has played a role in this pattern, a number of upper ridges have also contributed to having warmer air move into the province, Hasell said. Winnipeg’s average temperature for November as of last Friday, before this weekend’s record-breaking weather, was already significantly above normal for the month, Environment Canada said. “Averages don’t tell you the whole story … but I expect we’ll still be above normal by the end of the month, even though we’re going to see colder and colder temperatures over the next several days,” Hasell said. With a low-pressure system passing through from west to east during this week, cold air will flow from the north — a shift that will bring progressively colder temperatures to southern Manitoba. The temperatures are expected to dip in Winnipeg below –10 C overnight on Wednesday, and by Sunday, Environment Canada forecasts a high of -14 C.With files from Riley Laychuk and Santiago Arias Orozco
