There is a huge number of Highs filling western USA from the coast to
the Continental Divide.

Meanwhile, we had a little drizzle this afternoon.

And the "Blocking High" extending from Northern Europe to the east of
Britain has broken. It's actually due to slide off down the east coast
of the Atlantic:

Which will leave the way open for a Low off Iceland to get to Norway.
So we should see a fairly large magnitude quake for that.

(Though it is slated to hit Svalbard, an island in the Arctic, on
Tuesday according to the above link. I dare say things will have
changed radically by Tuesday.)

It will be interesting to see if the first of those US Highs reaches
the coast before then. One in Texas is well on its way already.
