I don't think I've seen such consistency at T+120 ~ T+240 (and beyond)
for high pressure to our NW and a steady run of north easterlies, with
all 19 runs more or less pointing to the same thing. Shame it's not a
month further ;-)


I wish I could understand these.



The way I understand it is that you click on a number in the double
line of boxes, and that represents the number of hours ahead the
charts below represent.

Then you look carefully at all the little pressure patterns in the
boxes below, and if they are all exactly the same then you can have
minimum confidence in that particular synoptic situation coming true.

If they are all different, you have no confidence in anything - and
need to go back to bed.

You will find that a number of people quote these charts on a regular
basis as a way improving their self importance, but as we all know
they are complete failures when it comes to the much more reliable
measurements, such as their skill in playing "Mornington Crescent".
