After a wet morning on Tuesday it brightened up after 14.10 that produced a maximum temperature of 8.3C at 15.14 being a welcome 1.2C above my long-term average. During the evening the barometric pressure continued to rise slowly as Storm Herminia eventually left our shores. With the cloud thinning the temperature held steady between 3.5C and 4C for much of the night but just after 04.30 the thermometer began to fall slowly reaching a minimum of 2.0C at 08.00 being 0.7C above average.
Wednesday began with relatively clear skies but what cloud there was, was high and thin. However, thanks to a deep depression over the Brest peninsula throwing cloud across the UK it began to thicken and the sun become much weaker after 08.30. The temperature continued to fall with a low of 1.7C at 08.30 but will now rise as the cloud cover increases, with the sun, sadly, becoming obscured.
The low air temperature produced a short lived ground frost that was evident on the grass away from any built up area. Its also produced misty and foggy conditions that wondered around and in the River Og valley between 08.00 and 09.00. The air temperature had recovered to 2.0C by 09.00. The fog thickened before 10.00 limiting visibility to around 300m.
The depression to the south will produce a glancing blow to the most southern part for the UK with thick cloud and heavy rain that, from the rain and cloud radar forecast, seems to be just to the south of our area.
Latest: Just discovered that the storm running across northern France has not been named in Britain because its effects are not expected to be as significant as storms which are named in the UK and Ireland although it is technically Storm Ivo named by the Portuguese’s Met Service.
We have had five named storms this year in the season that runs from September to the following August. The previous year of 2023/2024 gave us 12 named storms. In the UK, storms are named by the UK Met Office, in collaboration with the Irish Met Service and Dutch Met Service with names chosen from a public suggestion list, excluding letters like Q, U, X, Y and Z. Storms are listed alphabetically when the final section has been made. Storms are named when a deep depression is likely to cause significant impacts with strong winds, heavy rain or snow.
