With a low of -32 at Winnipeg airport this morning, this marked the 21st time this winter the airport has recorded a low of -30 or lower. There were 3 occurrences in Dec, 10 in Jan, and 7 in Feb.
As for -30 temperatures in March, it does occur from time to time. Last year we hit -30.8C on March 5th, virtually a year ago to the day. And back in 2003, 6 of the first 8 days in March registered lows of -30 or lower. At Winnipeg airport, the latest -30 reading in March was March 24, 1974 (-31.7) while the latest -30 reading ever in Winnipeg was on March 30, 1882 (-31.1)
That being said, it looks like we'll see another -30 night tonight although we get a bit of a southerly wind overnight which may prevent the airport from bottoming out as cold as last night. Then that should be the last of the -30 weather, dare I say for the season?! We have a nice warming trend over the weekend into next week, with temperatures near freezing next week. Hopefully, this upcoming mild weather lasts for awhile, but I'm concerned that we'll fall back into the same pattern of the past few weeks with a return to below normal temperatures by the end of next week. Hopefully, that doesn't pan out.
Note the record high for Winnipeg today.. 16.5C in 2000. That's what can happen here in early March when there's no snow on the ground! That year we lost our snowcover by the end of February, leading to some exceptionally mild weather early in March.
