Cold end to mild winter.. warmer weather returns by weekend
It was a bit of a shock to the system this morning as Winnipeggers woke to -25C temperatures and windchills close to -40.. readings that have been relatively rare this winter. The cold snap was ushered in by an Arctic cold front that slipped through southern Manitoba Sunday night bringing about 3-5 cm of fresh snow, along with gusty north winds to 70 km/h that caused poor visibilities in blowing snow and led to many highway closures last night. Brighter, calmer weather is in store today, but temperatures will remain well below normal with highs only in the mid minus teens and lows tonight back in the -20s. The good news is that the rest of the week will see a moderating trend with temperatures climbing steadily each day this week. Highs by Friday in Winnipeg will be rising to -3C and above 0C over the weekend.
Winter of 2015-16 is 9th mildest on record in Winnipeg since 1872
Winnipeg temp summary since Dec 1st About 3 out of every 4 days was above normal
Despite the cold end to February, the month finished 2C above normal at -11.1C, our 6th consecutive month above normal. The month capped off a mild winter in which all 3 months were above normal. In fact, the 3 month period of Dec-Jan-Feb finished as the 9th mildest winter in Winnipeg since 1872 with an average temperature of -11.3C (normal -14.3C) The strongest El Nino in the past 50 years was a prime reason for the mild winter, helping to bring more frequent and persistent mild airmasses from the Pacific, while minimizing intrusions of Arctic airmasses from the north. The result was a fairly tame winter for southern Manitoba, with 3 out of every 4 days averaging above normal. In Winnipeg, there was only one day with a temperature of -30C or colder (-32.3C on January 17th) A normal winter would see at least 12 such days. Snowfall has been slightly above normal in Winnipeg, mainly due to a snowy week in December in which 41 cm of snow fell from the 16th to 23rd. As of Feb 29th, snowfall has totalled 101 cm in Winnipeg, about 17 cm more than average to the end of February.
