The rain set in just after 08.00 on Monday and continued for many hours, sometimes very heavy. The rainfall total was 15.3mm making it the wettest day since 10th June when 25.1mm was recorded. The rainfall total for July now stands at 50.mm, exactly 9mm below the 35-year average.
The past night has been cloudy with the thermometer not falling below 15.1C, which was 3.3C above average.
Tuesday arrived with hang back of thick cloud from the depression that crossed the area yesterday although the wind has moderated a little, as the barometric pressure continues to rise, after a peak gust of 23mph on Monday making that the windiest day in July.
Monday saw the thermometer rise above average (+1.6C) with a maximum of 24.3C at 13.09 before intermittent cloud cover increased. Apart from a few spots of rain at 18.30 it was a dry day and the UV level rose into the very high category again.
The cloud cover thickened overnight from the advancing depression, which meant it acted as a duvet to minimise heat loss into the atmosphere resulting in a mild night with the thermometer not falling below 15.4C, which was 3.6C above the 35-year average.
Rain started to fall just after 06.00 on Tuesday morning as the depression slowly moved eastwards giving just 0.4mm by 08.00.
The rain total for July currently stands at 35.6mm with the loss of moisture into the atmosphere through evaporation now equivalent to 103mm of rainfall.
The barometric pressure has been falling for the past twenty-four hours indicating the approach of the depression so that by 08.00 Tuesday the reading of 1001.9mb was the lowest this month.
Update on Tuesday at 17.45: rainfall since 08.00 to current time amounted to 14.8mm making it the wettest day since 10th June (25.1mm). A cool day due to thick cloud and hours of rainfall with maximum only 18.9C, which was 3.8C below average.
Sunday brought more sunshine than on Saturday, 9.3 hours also a warmer day who a peak temperature of 22.6C, almost average. It was another dry day but due to variable cloud, especially around midday, the UV level fell to high after several days at very high.
A cool and dry night followed with the thermometer falling to 9.2C being 2.6C below average. The result was radiation fog from the moisture condensing in the atmosphere as the temperature fell, not low cloud. The initial visibility was 100m but by 08.00 on Monday the sun, shining brightly after dawn, meant that the fog had evaporated.
With just three days left in July the rainfall total of 35.1mm is 59% of the 35-year average. However, with the barometric pressure beginning to fall in advance of a depression in the south west approaches, rain is expected on Tuesday.
A wet morning on Saturday due to being on the western edge of a weather front that slowly drifted northwest. The rain ceased just before noon after depositing 3.4mm. The afternoon saw sunny intervals, 5.8 hours in total, that lifted the thermometer to 20.7C, which was 2C below average.
After a dry and mild night, minimum of 13.2C, there was variable sunshine after dawn that lifted the thermometer to 16.1C at 08.00.
Friday was another very warm day as the heat from the continent slowly ebbed away although there was much residual atmospheric and heat including from the ground, which at 08.00 on Thursday read 20.9C at a depth of 5cm. The maximum reached was 25.2C being 2.5C above average.
Although during daylight hour it was dry a light shower occurred just after 23.00 amounting to 0.3mm. This brought the July total to 31.7mm whereas evaporation accounts for the loss of equivalent rainfall of 93.0mm
Saturday arrived with thick cloud, being very dull, from the weather trough just to the east.
