It is now spring! And despite the massive continuous blizzard that appears to be going on outside, we're supposed to be getting warmer. Any day now...
You may have seen my analyses of Summer and Fall for Edmonton weather. Hopefully ever since then you've been on the edge of your seat awaiting the results for winter.
Wait no longer! The winner for winter is: The Weather Network. (three times in a row!)
Scores for winter (out of 100):
- Weather Network: 70.91
- Weather Channel:67.71
- Environment Canada:66.79
- Global Weather:65.45
- TimeandDate.com:60.05
- CTV Weather: 57.38
Weather or not (PUN!) temperatures and precipitation are actually tougher to forecast in winter is a question better asked of the actual meteorologists. My suspicion is that at least part of the continued decrease in scores is that trace levels of snow are harder to measure as precipitation than rain, but that's mostly just a guess.
Some fun facts!
Best high temperature prediction: Weather Channel 1-day prediction: 71.84%
Best low temperature prediction: Weather Network 1-day prediction: 68.64%
Best precipitation prediction: Weather Network 1-day prediction: 76.67
Worst high temperature prediction: TimeandDate.com 6-day prediction: 36.30%
Worst low temperature prediction: TimeandDate.com 5-day prediction: 37.64%
Worst precipitation prediction: Environment Canada 6-day prediction: 54.70
Some graphs!

Have a good spring!

From my water and ice engineering courses, I know that the gauges used to measure snowfall tend to be much less accurate than for rainfall.
Is there anywhere I can look to see what exactly your methodology is? Particularly how you verify POP, especially when no POP is given (e.g. EC past Day 2).
I Finally Got Helped !! I'm so excited right now, I just have to share my testimony on this Forum.. The feeling of being loved takes away so much burden from our shoulders. I had all this but I made a big mistake when I cheated on my wife with another woman and my wife left me for over 4 months after she found out.. I was lonely, sad and devastated. Luckily I was directed to a very powerful spell caster Dr Emu who helped me cast a spell of reconciliation on our Relationship and he brought back my wife and now she loves me far more than ever.. I'm so happy with life now. Thank you so much Dr Emu, kindly Contact Dr Emu Today and get any kind of help you want..
