Europe gets its heat from Saharan Africa. Their weather patterns are not related to ours.

Europe doesn’t just get suddenly “hot,” typically wind patterns will shift and heat from the desert travels unimpeded across the Mediterranean and eventually settles over mainland Europe. The continent is literally surrounded along its south and east by some of the hottest jurisdictions on earth. You expect that to affect European climate, including that of the warm Mediterranean regions themselves.

 

Yup, my wife was over in London 3 weeks ago visiting our daughter, it was 37 and at night went down to maybe 25...thats really frigging hot for a place like London that has minimal A/C plus all those stone buildings.

 

Its not unusual for places like that to hit the mid 30's, heck the summer of '76 saw London hit above 30 for 15 days running and in some spots there was a 5 day run above 35

 

I think this summer in Victoria has been pretty normal, a few days of rain, some warm days but on average its been a non-eventful and nice summer

Weather patterns are related all over the globe.  For example a "blocking high"* causes the jet stream to loop high to the north, which when it happens here (common during El Nino events) causes prolonged warmth in the west and prolonged cold over eastern North America as it loops back south and - looking the other way - causes lows to form further west in the Pacific than they otherwise would, thus affecting much of the ocean and parts of eastern Asia.  The effects ripple out from there, becoming less pronounced as they go.

 

And all of this, in this example, is caused by a heating event in the waters of the South Pacific.

 

The shift in wind patterns that cooked Europe was caused by something...probably the same or similar sequence of causes that brought major heat waves there in past years/decades.  I don't know the specifics.

 

* - for those unfamiliar with the term: in the northern hemisphere weather systems - and thus patterns - of all kinds generally tend to move from west to east.  A 'blocking high' is a stable high-pressure area that, rather than moving west-to-east as one would expect, instead just resolutely sits where it is for an extended period...and in so doing blocks the normal movement of other systems - it's in the way - and thus gets its name.  That we've had a trough off the coast for so long this summer tells me there's a blocking high somewhere that's preventing the usual shifts.

For sure, weather is related as it’s contained around our globe, but what I mean is whatever happened off the coast of Vancouver Island this summer did not directly create Saharan outflows in Germany. If it had I think we’d be hearing meteorologists discussing how a cool summer in Canada was to blame for a hot summer in Stuttgart.

Further to my post above, there's an article in today's T-C that talks about jet stream blockages and how weather is affected.  Gives more detail than I did.

some people are seeing lighting (including someone just up the street from me) but I haven't seen any all night so no idea.

At times the skies lit up 2-3 times in a minute. I sat in the yard listening to Neil Young for about an hour and a half before the lightning stopped or became too infrequent to notice.

It looked like it would have been centred on the San Juans/the Bellingham area.

Seattle metro area got about 1000 lightning strikes last night, most if not all within a 3-hour period.

 

A smaller storm rolled up the far side of San Juan Island from south to north, and that's what you'd have seen.

When I looked at the radar weather, you could clearly see the system moving north and slightly east at the time. We were cloudy in Victoria but the system remained to the east southeast. It was fun watching the lightning display. Only sheet lightening, no forks to be seen.


Don't be so sure.:cool:

Between 30 and 35mm has fallen thus far in the vicinity of the reservoir.

 

It's been a very, very long time since I've seen this much rain fall in a five hour span.

I can well believe the 30-35 mm out west, given how hard it was raining in town this afternoon.
