Hi Paul, do you consider upper air forcing, ageostrophic effects etc in the
upper air when you try and put weather to the surface charts?

That is why I am still going for long extended dry spells this summer. OK
that is more for England and Wales than Scotland and NI but I still fancy it
will hold good as the ascending moist air continues to get forced
northwards. No proper rain down here as you know for weeks now and I cannot
see much in the future either (apart from one or two storms or the odd cold
front if we are lucky). This does not mean it will be high pressure but you
don't need high pressure for it to be predominantly dry, just the right
upper air patterns to produce the ageostrophic effects that will produce
descent as opposed to ascent.

Ciao,

Will
