Midday temperatures:-
2nd 7C (Eventual 0900-0900 max 8.4)
3rd 12C (0900-0900 max 12.4)
4th 5C

The forecast was much the same for each day. The 7th saw a good deal
of sun, but the edge of the cloud was very close to the north. 3rd -
basically no cloud within 100miles. Today, sunny spells this morning,
but thicker cloud just to the south, breaking near the south coast.

A mainly blue slot now approaching so the temperature should rise 2 or
3 degrees soon. Much of southern/central Cornwall around 6-8C colder
than at same time yesterday.

Similar synoptics, very different weather.
