But ridges generally produce warmer conditions at this time of year...
They do - I perhaps should have written "cooler air aloft", as 850hPa
temperatures were forecast to drop a good 10C or so.
However, even down at ground level that would give a much more pleasant
(IMO) fresher feel to things - I'd rather have clear skies and 850hPas of
near freezing in summer than a drizzly day with 10C 850s. For one thing, the
former would give a wonderful cool morning and evening, with the liklihood
of a bit of cloud bubbling up during the day.
