The evidence that the sun is getting stronger was in the UV level on Tuesday, during the strong sunshine periods, when the peak level was 4.4, logged at 12.21. This high was at the top end of the ‘Moderate’ level and the highest since 17th September. The thermometer reached a maximum of 16.1C at 14.23 being 5.4C above my long-term average whilst under clearing skies the temperature dipped away to a low 3.9C at 03.47 early Wednesday. The radar showed cloud drifting in and mist developing after 05.30 early Wednesday that allowed the temperature to rise to 8.3C by 08.00, helped by short bursts of strong sunshine through the variable early morning cloud.
By 08.00 on Wednesday the cloud had began to show larger areas of thin cloud and greater breaks, that allowed more sunshine to break through. The ridge of high pressure has developed further, which is likely to mean a dry day, having risen another 4mb since Tuesday with a reading of 1026.0mb at 08.00. With the high pressure dominant today the breeze should be light again, yesterday there was a maximum movement, couldn’t call it a gust, of just 10mph, most of the time the anemometer just slowly rotated.
The centre of the high pressure is currently off the east coast of the UK, as a result of this relocation the wind will back from northeast to southwest as the morning progresses. We have not seen an air stream from the southwest since the 5th, a much warmer direction than from the northeast.
