Hi Jon,

We didn't manage such dizzy heights in the South Hams (max +15.9 deg.
C) but the *mean* temperature since midnight last to now (21:10) makes
today the second warmest day of the year so far: +12.5 deg. C. The
warmest was 21st April with a 24-hr mean temp of +12.6 (Tmax = +18.1
deg. C).

What may be an interesting feature this Summer if the dry surface
conditions continue is very high surface temperatures. With little
surface moisture to evaporate more sensible heat will be available for
ambient temperature rise. We may see some good super adiabatic lapse
rates!

Regards,
Richard.

Hello Richard,

Good point, although I hope not as 20C is about my limit. Although I'll take
a few more degrees if it results in some good storms, not that I've seen
many here (e.g.1 last summer, June IIRC, and only 1 or 2 the summer before
that ).

Noticeably humid too today as you commented, although it felt less so by
evening when the cloud broke.

Jon.
