Heat builds!

The southerly air brought the forecast hotter weather as the thermometer soared to 25.7C, which was 4.7C above the 36-year average. The morning was dogged by light drizzle that was not measurable.

Under clear skies the temperature dropped away to 11.0C overnight, just 0.5C below average, with fog forming in the early hours limiting visibility to 600m but by 07.30 on Friday it had completely evaporated under the influence of strong sunshine.
