Wednesday was totally dominated by thick cloud that gave a sunless day, only the fourth this month.
The temperature, not surprisingly, was down for the fourth successive day with a maximum of 16.3C being 0.5C below average.
It was a dry day and night so the May rainfall total stands at 53.2mm, which is 8mm below the May average.
It was another warm night when the thermometer did not fall below 14.6C.
Thursday arrived with thick fog limiting visibility to 200m initially. However, by 7am the fog was beginning to thin and glimpses of brightness began to brake through.
The mild nights and days produced a temperature in the soil, at a depth of 5cm at 08.00 of 16.8C, the warmest at this time of day since 28th August.
