The current warm spell affecting central North America will threaten some all time records for March warmth over southern Manitoba over the next few days. In Winnipeg, daily record highs are likely to be set over the next 5 days, starting with today with a record high of 13C forecast, 2C above the current mark of 11.1C set on this date in 1927. The warmth really starts cranking up on Friday, with brisk southerly winds sending temperatures up to the 20C mark over southern Manitoba. If Winnipeg hits 20C or higher Friday, it would mark the earliest date on record that the city has ever hit the 20C mark, a full week earlier than the current mark of March 23, 1910 (22.8C) It would also be only the 4th time on record that the city has hit the 20C mark in March, and the first occurrence in over 65 years. (UPDATE: Official high temperature Friday was 19.9C.. just missing an official 20C day, but it's the earliest we've ever hit 19C)
20C days in March.. Winnipeg (since 1872)
1. March 27 1946 ... 23.3C
2. March 23 1910 ... 22.8C
3. March 28 1938 ... 20.6C
A slight cool down is forecast for Saturday, but temperatures are still forecast to be at record levels in the mid teens. Another push of warm air Sunday into Monday is expected to send temperatures into the 20s across southern MB, including Winnipeg where the all time March high of 23.3C in 1946 will be threatened. A cold front pushing through Monday night into Tuesday will bring cooler air, along with showers and possibly even the season's first thunderstorm of the year. All in all, looks like a potentially historic March warm spell on tap over southern Manitoba.
