MILD AND SNOWY SECOND HALF.. February 2007 featured a split personality over Southern Manitoba. The first half of the month was dominated by clear and cold conditions as Arctic high pressure maintained an icy grip over much of the Eastern Prairies for 3 weeks. Every day from the 1st to the 15th was sunny.. with only 0.4 cm of snow recorded during the period. Temperatures however were frigid.. averaging some 12 degrees below normal for the period with daily highs in the minus teens and minus 20s, and lows in the minus 30s. In fact, temperatures dipped to -41.7C at the Winnipeg airport on the morning of Feb 5th.. the city’s first -40C reading in 3 years. By the 16th however, the weather pattern changed allowing temperatures to finally edge above normal, where they generally stayed for the rest of the month. In fact, temperatures never dropped below the -20C mark after the 18th at my station. The mild finish however wasn't enough to offset the cold first half, and February 2007 finished over 3 degrees below normal.. the first below normal month in Winnipeg since last October. As is often the case however, the milder temperatures in the last part of the month were accompanied by snowfall. In fact, there was almost daily snowfall in Winnipeg from the 20th to the end of the month, totalling some 21 cm at my location over the period. Even heavier amounts of snow were recorded outside of Winnipeg with three separate storms bringing some 15 to 25 cm through western MB, the Interlake, and southeast Manitoba. The net result is that February 2007 ended up snowier than average over much of Southern MB, including Winnipeg whose 21 cm was some 50% above the average February snowfall of 14 cm. Snowdepth at the end of the month was a season high 44 cm. All in all.. a mild and snowy finish after a clear and cold start.
