The above normal temperatures that have characterized most of November will continue through the end of the month before a change to colder weather just as the calendar flips to December. In the short term, generally quiet weather is expected over the next few days with cloudy to partly sunny skies, and afternoon temperatures near or slightly above the freezing mark, some 6 degrees above normal for this time of year. November 2009 will end up as the 3rd or 4th warmest November on record in Winnipeg since 1872, and barring any measurable precipitation over the next 3 days, will likely end up as the driest November since records began with only 0.5 mm total precipitation for the month.
By Tuesday, an Alberta clipper system will track through the Manitoba lakes and bring a threat of snow, especially through the Interlake areas. Gusty northerly winds on the backside of the system will draw in colder temperatures over southern MB by Tuesday evening, with temperatures finally dropping to normal or even below normal values for the beginning of December (normal highs -7C, normal lows -15C)
