After experiencing the 4th warmest winter on record a year earlier, the winter of 2012/2013 was a bit of a shock.

After reaching a balmy 2.6°C on January 10, Winnipeggers did not see above freezing temperatures until March 28. This 76-day streak without reaching the freezing mark was the 20th longest since 1872. Longest was a 108-day streak from November 9, 1996 to February 24, 1997. A list of the longest streaks can be seen here.
The snow was the biggest story of the winter. From November to March, only February saw below normal snowfall. March saw more than double the normal snowfall with 36.4 cm, 22nd snowiest. Both January 2013 and November 2012 were 20th snowiest. By the end of January, Winnipeg had already received an entire year's worth of snowfall (since October). By the end of March, 160.2 cm had fallen since October 1, the 13th snowiest Oct 1 to Mar 31 period since 1872. A list of snowiest Oct 1 to Mar 31 periods can be seen here.
The high snowfall totals created one of the deepest snow packs in years across southern Manitoba. A depth of 58 cm in Winnipeg on March 18 was the deepest snow pack since the great blizzard of April 1997. Snowbanks were massive, making it difficult to move around.

27 consecutive days saw below normal temperatures from July 19 to August 14. In this period, highs averaged 22.3°C and lows 8.7°C, both some 4 degrees below normal for the period. The maximum temperature was a measly 25.2°C, startling when you consider the fact that normal highs in the period are 25 to 27°C. 4 days didn't even reach 20°C, while a total of 20 days saw morning lows in the single digits. Many nights saw lows flirting with record lows. On many occasions it got down to between 2 and 5°C across southern Manitoba, 7-10°C below normal.
Winnipeg reached a record low on July 27, dipping to 5.6°C. That broke the old record of 5.8°C in 1978. A full list of records broken on this day can be seen here.
#8 - Twin May rainstorms
Two major Colorado Lows in the second half of May dumped excessive amounts of rainfall in the Red River Valley.

Winnipeg was spared the worst with ''just'' 15-50 mm of rain. Southern sections saw 30-50 mm while northern and central parts saw 15-30 mm. Winds were the main concern, with gusts up to 80 km/h on the 20th.
