Hard to say without knowing exactly where these places are. I know most of BC gets the northern jet quite a bit most winters.


A simple google search can do wonders. They are in the North/Central BC Interior (of course Shawnigan said it too). Generally cold and dry in the winter. Mean jet is aimed farther south.

Did you actually look them up? The 3 locations he mentioned are quite far apart. Clinton is in south central BC, Burns Lake is right in the middle, and Dease Lake is far north. Very different as far as relation to the northern jet.

 

I'd imagine their overall dryness is tied much more to being on the lee side of the coastal mountains. Clinton is certainly much more in the path of the winter jet than Dease Lake. 

 

But given that they are over 800 miles apart, there are probably some significant climate differences overall.

Yes, all three. And now you are just splitting hairs.

800 mi is not splitting hairs.  :lol:

 

That is a huge difference in terms of how close they are to the northern jet. And southern BC is definitely in the path of the northern jet quite a bit during most winters.

That part isn’t. They are relatively far flung. Still, my general point stands. No need to try to reinvent the wheel here.

From what I can find online, it seems like areas from the central interior down to southern interior BC are definitely wetter than here in the winter. Prince George, for example, averages 2.14" in January, or about 4x what Denver does. So my guess that they are wetter in the winter, due to being more in the path of the northern jet, seems to have been correct. 

 

Interestingly, they definitely have a drier period in late winter/early spring. March is actually their driest month of the year. But Prince George averages 1-2.5" every month of the year, so not a ton of variation.

 

Far northern BC, of course, is different.

Am I way off base about their winter means being drier up there since the jet stream is more frequently south of them on average? You would know the details of those climates better than I.

I would expect the jet to be south of those northern areas pretty frequently. Not sure if it matters that much as those lee side locales can get totally rain shadowed even when the jet is active. Just going off memory here, I think the often dry Chilcotin region has historically seen their biggest snowfalls earlier in the season. I guess that could possibly be linked to the jet typically progressing southward during that season.

Edit. Looking at locations on the north coast, their rainfall peaks in October, with September and January being about equal as the 4th wettest month. So you may be correct with the southward jet idea.

Yeah, it would make sense that they are all shadowed in the winter. But they still all get more precip in the winter than the spring or fall, which is different than here.

Yes, the northern polar jet progresses south normally over the winter. Which is even Seattle/Vancouver are wetter in Nov/Dec than January on average.

 

But that doesn't mean the northern jet isn't a major influence during the winter for BC...it's the primary source of storms. And that's why those interior BC locations are easily wetter than here in the winter, and see a lesser "wet season" in between fall and spring - which we don't see here at all.
