The Great Lakes influence weather in southern Ontario. Here are some URLs, and sample images where available...

Up till now we've had mostly localized frost events in Eastern Canada this season. The FIM progs show a cool air mass sliding southeastwards from the Arctic, through Ontario/Quebec/Maritimes, during the 17th to the 20th. Much of Eastern Canada looks like it'll be experiencing frost 2 or 3 nights in a row.
Note that the American maps use "ye olde Fair-n-hot" temperatures. The forecast is for temperatures 2 metres (approx 6 feet) above the surface. While the Golden Horseshoe escapes the 2-metre frost, there will likely be ground frost outside the areas covered by the red 32 Fahrenheit line. To cut down on map clutter, I'm only posting 06Z and 12Z (2:00 AM EDT and 8:00 AM EDT respectively) forecast maps.

The August 12-14 topic http://forums.accuweather.com/index.php?showtopic=31812 in the American forum is based on the same systems/conditions. They only care until it leaves the US east coast. In Canada, it'll work down the St Lawrence, and through Atlantic Canada, hence the 2 extra days. There are a few rainfall maps in the US thread. Instead, here's a few maps from CMC of the event...

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. 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...
