November 2012, Cold And Snowy

November 2012 stats, CLICK to enlarge
     November 2012 ended colder than normal, which is something that is long overdue. It marked the end of a streak of warmer than normal Novembers going back to 2003, our last colder than normal November, 9 years ago. The monthly high temperature was a measly 4.9°C, the lowest November maximum since 1995.

     Snowfall was another highlight with 40 cm of snowfall through the month, almost double the normal. This high amount was mainly due to a significant Colorado Low on Nov 10-11, and from multiple back-to-back clipper systems late month.

     The Colorado Low on Nov 10-11 was very significant. 20 to 30 cm of snowfall fell over the city, making it the most significant snowstorm since late December 2006. What is important to note however is how fast the snow came down. 10 to 15 cm of that fell in just a few hours in the evening of Nov 10 under blinding heavy snowfall. Even heavier amounts fell to the northwest of the city, with 37 cm in Portage, 40 to 60 cm in parts of the Interlake and 65 cm in Mafeking (western Manitoba).

     Other than that, gloomy skies were the trend of November. The month started cloudy or mostly cloudy day after day. The first mainly clear day was not until Nov 14, after almost a month of day after day of cloudy or mostly cloudy skies.


  1. Change of plans for the Fall summary. Wont have it up until Monday evening.

  2. Got some rain in the city early this morning. Looks like about 0.5 to 1 mm fell with highest amounts in northern sections of the city. Lots of melting this morning with above zero temperatures, but falling temperatures this afternoon will freeze everything up.

  3. Tomorrow's system looking to stay mainly to our north, where heavy snowfall will fall in central Saskatchewan into central Manitoba. Temperatures will rise tonight in southern and southeastern Manitoba as we tap into warm air in the southerly flow ahead of the system. We could see temperatures near 2 or 3°C in the Winnipeg area in the morning and early afternoon. There will be a chance for showers however associated with the system. The best chance will be in the morning. Amounts will vary as precipitation likely wont be very organised with perhaps 1 or 2 mm of rain in the heaviest hit areas. Some of this may fall as freezing rain in the beginning, especially to the north of the city.
    Temperatures will steadily fall behind the cold front late tomorrow afternoon with temperatures likely all the way down to around -5 to -7°C by 6 PM.

  4. Scattered showers and drizzle moving towards the city, which will give us a damp morning. This afternoon as mentioned yesterday, will see a dramatic cool down.
