Survey Says...It's going to get cold next week!

We've been semi-spoiled the past couple of weeks in the temperature department.  Sure we had a couple days where highs were in the teens but overall not too bad.  That will all be changing as the weekend and next week approach.  Whenever I forecast I always like to see what temperatures will be above the surface, typically around 850mb (or roughly 1500 ft up).  That will usually give me an idea if any warm or cold air will be moving into the forecast area.  Looking ahead into next week it doesn't look like we will be seeing a warm up anytime soon.  Temperatures look to stay below average through a good part of the week and possibly into next weekend!  Click here to see a looping image of the temperatures ( in degrees celsius) at 850mb.  The loop begins Tuesday night and runs through next Sunday, the 14th.  It runs every 12 hours: 6am and 6pm.  The darker pink and purples indicate the cold air coming in from northern Canada and notice how it pretty much stays in place for the next 10 days.  We really don't see any big warm ups anytime soon!
