WeatherWatcher: Weekly report, more of the same - rain

Sunday, October 28, 2012

  • Week ahead - rain
  • First possible snow event could be soon
  • Last week's weather data
For our week ahead we are looking at a lot of rain. Monday through Wednesday we will likely have rain off and on as a series of weather fronts makes it through our region. Thursday looks like it might slow down a little on the rainfall and bring in just showers.

Halloween will be rainy and cool for all the trick-or-treaters, so make sure all those costumes are water proof!  Friday is looking like our only break from the rain this week before more weather systems move in for the coming weekend.

First possible snow of the season in November.  I've been keeping a close eye on a cold air mass that is building and getting colder and colder in western Canada. A lot of the longer range computer models I've been reading are suggesting that this cold air may break lose and move into our area some where around the weekend before Thanksgiving.  Of course there is much uncertainty when looking this far ahead, but keep in mind we are entering the time of year when these events are possible.  It's never too early to prepare for winter weather.

Last week's data:
I have included some graphs below, first one is last week's daily average temperature compared to the 3-year average. The second one is the month of October 3-year average, compared to this year October so far. You can see our cold air mass that came in last weekend shows up as a low dip on the red line in the second graph.

Daily Average temperature last week.
