Jetstream
 

I always thought that the jetstream ran west to east. How unusual is it for
parts to go into reverse?

I've noticed an east to west flow over Newfoundland at the moment, with
another fragment on the west coast of Canada doing the same thing:

Hi Tom,

You may find this link better for the 300hPa flow -

It looks mighty perturbed, save for mose parts of Asia.

It's not that unusual but it does reflect what's going on over northern
europe. The main jet stream is running across the atlantic at about
40-45degs north - which for the time of year is unusual. Because of
this there is a large upper high over much of Canada giving an e'ly jet
of about 90kt across Newfoundland.

It's rare to hear the jetstream mentioned on the
weather forecast in the UK whereas in the US
much is made of it. I lived in DC and when the
jetstream moved south we used to get Canadian
weather, north and we got Mexican weather. It
seemed quite a reliable indicator at any time of
the year.
