The web page is http://www.blitzortung.org/Webpages/index....n&page_0=30 One of the first things I did was to turn off the annoying sound effects, and also the detector locations, which show the triangulation. This makes for a cleaner map, and allows me to listen to internet radio.

I'm getting really starved for systems to track. sad.gif On the NAEFS EPSgrams, the CMC global model shows a precip event for Toronto and Ottawa around the 11th/12th (Wednesday/Thursday). The FIM model shows a wave/trough going through southern Ontario, up the St Lawrence, and then the Atlantic provinces. There's a thread in the US forum about the potential for severe wx in the NE around that time. It's just getting within the extreme end of CMC's range, so I have some precip map plots...

This covers spring+summer+fall (and possibly into winter) so it doesn't fit into the Spring thread. Recent CFSv2 monthly forecasts have been showing a persistent cool anomaly around Lakes Superior and Huron. The effect often stretches out to the GTA and Hamilton. The monthly progs only go through October, so it's a bit early to speculate about winter.

Assuming the prog maps below do verify, and continue into next winter, what would the side-effects be? I can think of the following...
  • obviously cooler temps for the affected areas
  • earlier freeze-up for Lakes Superior and Huron
  • shorter lake-effect-snow-season for snowbelt areas adjacent to Superior+Huron
  • earlier start to snowfall season
  • possible weakening of the "Toronto Snow Dome"
Any others that people here can think of?

Since it covers summer+fall+winter, it doesn't fit into a neat topic. Anyhow, Weatherbell has a video that comes out approx 9:00 AM Saturday mornings, and is available to the general public. Weatherbell susbscription not required. Today's video is at http://www.weatherbell.com/saturday-summary-april-5-2014 It deals mainly with the US, but here's what I could glean for southern Canada. A summary follows...
  • he points to Jamstec models which forecast a weak El Nino this summer, dying by winter
  • Weatherbell forecast for summer
    • cool blob (-2) centred over Minnesota+Wisconsin covers Ontario+Manitoba+SE Sask
    • rest of southern Canada looks normal temps
    • precip dividing line is central Ontario; 20% or more above average to the East; approx average to the west
  • Weatherbell forecast for fall
    • cool blob (-2) centred over Great Lakes, extending SSW
    • rest of southern Canada from Central Sask east slightly below normal temps
    • southern Canada from Central Sask wast has normal temps
  • Weatherbell forecast for winter
    • cool blob (-2) centred over Golden Triangle
    • rest of southern Canada from Sask east slightly below normal temps
    • Alberta normal
    • BC, especially the coast, warm
    • Central Ontario and East, 80% or less of normal pcpn
    • ditto for BC and especially west coast
    • rest of Canada approx normal precip

I hate to rain on your parade... or your snowbanks, but here goes. Note that the purple line labelled "32" is the surface temp freezing boundary. Maybe people don't want to be the bearer of bad news, which is why nobody else took it on.
