However, I would have thought that Kamloops would have more days of thunderstorms, since its inland and gets daytime heating effect much more so, without the oceans influence. From my understanding, areas near the ocean tend to have a lot of atmospheric stability, and unstable air is key to thunderstorm development. Seems to me that Kamloops should be prime for big storms when cold fronts cross the interior and clash with the hot airmass. I wonder if its all the hills in Kamloops that work to lower the number of days where the atmosphere conditions are unstable enough to trigger storms? Its certainly interesting, though Kelowna is fairly flat and they only get 14 thunderstorm days, but perhaps the lake has an influence on that?
One thing to consider is that some areas may be susceptible to more intense thunderstorms, even though they may not have a large number of thunderstorm days statistically. So it could be that even though Kamloops only has 6 more thunderstorm days than Abbotsford, the storms there may often be more intense then that of the storms in Abbotsford.
What are all of your thoughts?
Southern BC has very stable dry summer air. That's why Victoria and Lytton have the driest summers in Canada. Thunderstorms need heat and humidity. Kamloops has the heat, but lacks the humidity. Williams Lake (with 23 per year) has both the heat and the humidity while Whitehorse does not enough of either to get as many thunderstorms (only gets 6.56 per year). Windsor, Ontario has the hottest and most humid conditions in Canada, and thus gets the most thunderstorms (33 per year).
EDIT: Very interesting site! It lists all the daily and monthly records that have taken place recently in Canada. Here's a screenshot showing recent BC monthly records...
