Daily range an exceptional 24.2 degC

Stevenson screen, open site, Vaisala HMP45C T/RH sensor, confirmed by
co-located MiG thermometers.

Adjacent Davis AWS showed 8.0° to 31.7° and precision thermistor in
Campbell Scientific radiation screen 8.1° to 32.5°C.

Second-highest daily range on my (35 year) personal record - the only
higher was 16 April 2003, which attained 25.0 degC (2.4°C to 27.4°C).

Exceptionally low RH - min 19% at 1615. This is the equal-lowest on my
personal records, with 18 June 2000. Several days this month have
already seen below 30%.

My figures for my Davis AWS on the 18th of July are 32.8°C maximum and an
11.7°C minimum with a minimum RH of 21%.
The maximum here today is 33.7°C so far but the minimum last nightwas 13.5°C
so the range is unlikely to be greater today.

Since my station is in a sheltered back garden the temperatures are probably
slightly higher than would be seen from a more open location required for an
official site.
