Ex tropical storm Ernesto still affecting us

Saturday started gloomy with thick low cloud and stayed that way all day. There was an hour or two in the morning with drizzle, thanks to ex tropic storm Ernesto, that was a nuisance but only produced 0.2mm of precipitation.

There very brief glimpses of the sun during the afternoon but limited to just 17 minutes in total.

An interesting aside is to note that the maxima of the last three days are almost identical with 20.3C, 20.3C and 20.4C.

The remnants of ex tropical storm Ernesto was the cause of the overcast and damp day on Saturday and also continuing to affect us on Sunday, which arrived again with overcast skies, low cloud and light drizzle.

Due to the cloud and wind, which got quite strong during Saturday afternoon gusting to 21mph, the temperature maximum was below average (-0.3) but conversely, a mild night followed with a 15.9C minimum, which was 4.4C above average.

Update at 17.15: effects of ex-tropical storm Ernesto felt all day with the temperature rising 2.7C above average with a maximum of 23.4C at 14.03 combined with high humidity of 73% compared to 40% often last month.

Early morning drizzle

Friday was day of broken sunshine, another to 6.51 hours, and a dry day with a maximum of 20.3C, almost average.

Cloud drifted in overnight reducing warmth radiating from the ground into space, so a mild night with a minimum of 15.2C, which was almost 4C above average.

Saturday around dawn saw a brief shower of drizzle, amounting to 0.1mm, that quickly passed but leaving the sky completely covered with thick cloud.

Sun returns after much rain

Rain from the second cold front on Thursday morning, that quickly followed the first cold front overnight, arrived just after 08.30 and produced another 6.0mm of rainfall. The total rain from both cold fronts totalled 17.5mm.

By 12.00 the rain had stopped and the cloud started to thin with sun breaking through consistently early afternoon giving us 6.42 hours.

The late sunshine boosted the temperature to 20.3C at 16.31.

A cool night followed with the thermometer falling to 9.9C that produced fog in the River Og valley that had dispersed by 07.00 as the sun got to work raising the temperature to 14.1C at 08.00.

Update at 18.30: another 6 hours of sunshine today brings the total for August to 117 hours, almost the average for the whole of August over the past four years (120 hours). No further rain today.

Two cold fronts bring much needed rain

Wednesday saw little sunshine, just 1.4 hours, with a mostly cloudy day and no rain during daylight hours. As a result the temperature was a little down on the previous two days with a maximum of 22.3C, still 1.6C above average.

A mild night followed with the thermometer slowly falling to a minimum of 15.6C at 08.00 today, being 4.1C above average, due to the thick cloud associated with the low pressure system to the west.

The first of the two cold fronts crossing the area brought the first rain just before 05.00 today producing 11.5mm with a heavy burst at 07.05 that measured a rate of 46mm/hour. There was a slight pause around 08.00 as the second cold front approached with the promise of more heavy rain.

Update at 10.30: rain stopped adding another 6mm (total of 17.5mm since 05.00) as second cold front moves away to the east leaving thick cloud and virtually still conditions.

at 18.00: cloud slowly thinned after midday with sun breaking through early afternoon, that lifted the temperature to 20.3C at 16.31, which was 0.4C below average. No further rainfall after 10.30.

Warmest day for a week

Tuesday brought us 4.8 hours of sunshine and although the wind was from the west, a maximum above average with 23.1C (+2.4C), the warmest day for a week.

Tuesday into Wednesday saw a very mild night with the thermometer not falling below 15.8C (+4.3C).

Wednesday dawned cloudy with, initially, low cloud over the Marlborough Downs giving brief drizzle that was not measurable, recorded as a trace, and no sun by 08.00 when the thermometer risen slightly to 16.7C.

Almost half way through August when the rainfall total is 17.8mm and evaporation stands at 44mm.

Update at 18.00:late afternoon sunshine lifts temperature to a peak of 22.3C at 17.30.
