Quiet, mainly dry spell after mid month with some frost and fog

Much cooler air behind the low bringing the wet weather, maxima the lowest of the Season to date with afternoon temperatures generally 6 -9c, it had been around 15c at midnight much of the Midlands. The summit of Snowdon had a decent snow cover

Wed 30th front stuck over SW England past few days, rain down there, rather cloudy S Wales and SW Midlands, plentiful sun N Mids and N Wales; chilly east wind, maxima generally 8 - 11c

Nature notes:

Not many Apples this Autumn, perhaps a reaction to the drought last Summer (conserving energy) with maybe a bumper crop next year?

Quite a small (secondary) Foxglove in bloom early month; various different flowers seen in bloom inc Daisy, Daffodil, Campion, Pink Clover - in small numbers all these; surprised to see a few flowers on the Holly tree (perhaps a reaction to the heavy pruning it received last month?)

Mid month Song Thrush heard in song briefly Coventry; plenty of Wasp activity still AG, Coventry; red Holly berries AG too; first Redwings heard calling as flying overhead at night.

Holly berries turned red in our garden month end too
