Slightly colder air reached Tideswell at about 1720z with the wind
changing from NW to SSE. Temp has fallen from 7.5° tp 6.0°. The change
from the mild NW'lies to the less mild SE'lies is very sharp.

The colder air reached Charlwood, the nearest MO site to me and some 10
miles to my east, in the small hours of this morning. It was 7.1C at
01:00, when the wind shifted to easterly (though only about 3-6 mph) and
the temperature began a steady fall, reaching 4.1 by 07:00. Since then
it's hardly varied, keeping between 3.5C and 4.1C.
