I was wondering why the blocks were set out the way they were. Over on
the western side the blue paterns were large boxes but the ones for the
wind in the middle are divided into small squares.

The warnings are for counties. Counties tend to be larger in the
western US.

Thanks for that.

is there any corresponence with extreme cold weather anywhere on an arc of 90
degrees of their occurence while there are extremely high temperatures
some 15 degrees down the road? (Wouldn't that be an handy tool if it
were so?)

I can't understand what you're saying here.

You probably won't be familiar with this but there is a marked
relationship with the epicentre of largish earthquakes and the storms
that appear in their shadow zones.

No, there isn't.

Recently I noticed that every hurricane in the North Atlantic last
season occurred with periods of dull, calm overcast, or even thick fog
on occasion, in western Europe.

I was wondering if the record cold weather in Germany during the severe
cell storm or whatever it's called, that held the tornados was also a
commonality.

No.

Thanks for that, too.

Would you mind supplying a link to the research if there is one online?
It would help me to put that one to bed at least.

There's no specific research, but a little knowledge of synoptic
meteorology indicates that there's no reason to expect a relationship ~
120 degrees of longitude apart in the mid-latitudes at the same time. A
strong trough moving out of the lee of the Rockies could have a very
deep trough associated with extreme cold anywhere or not at all. The
last two big cold events in Germany that I can find any info on (16 Nov
2000, 23 Dec 2003) were associated with 1 weak tornado and none at all
in the US.

No research on the topic has been done because there's really no reason
to do it. There are an infinite number of things that could be compared
to tornado occurrence in the US. People start by working on those
things that there's some physical reason to believe have a relationship.
Extreme cold in Germany wouldn't be at the bottom of the infinite list,
but it wouldn't be close to the top.
