There should be plenty of data on this spell but IIRC, most of it
concerning dates when there were severe tropical cyclones.

It is ordinarily a spell for fine weather in Britain, which is
somewhat like that of North America east of the Mississippi and Oregon/
British Columbia. But I don't know anything worth knowing about North
America east west of the Mississippi.

I dare say we are all about to find out a little more now that we have
the years first decent spell. Might even be able to mow the lawn.

Similar spells this year:

Jan 8th to 15th 11:37.

Jan 30th to Feb 7th: 05:03.

Mar 7th to 14th: 17:14.

Aug 23rd to 30th: 23:50.

Sep 22nd to 29th: 05:04.

Oct 21st to 28th: 11:55. (Which, as with the one for August, doesn't
come that close. But it is the start of a sequence.)

Oct 28th to Nov 6th: 23:14. (Which runs it pretty fine, though I can't
say much for the following spell: 04:04.)

Sept 29th to Oct 7th: 08:12 is only vaguely related as is: Oct 14th to
28th: 20:03 but these things are the shape of things to come, through
a glass, shadowed. We move and forget them.
