Monday 17th November
The temperatures have been going down and down over the last two days as the colder Arctic air arrives and dispels the last of the warm, most air. The thermometer did not get above average on Sunday, the first below average this month, with a maximum of 9.0C at 10.07, being 1.3C below my long-term average for November. After all the rain last week there was a slight drying up with another dry day following Saturday.
The temperature dropped to 3.9C at midnight before rising again to reach 5.1C at 02.00 as a weather front and associated cloud passed south across our region. As the cloud moved away the sky became clear and the temperature to begin to drop steadily, reaching a low 2.6C at 06.24 early Monday being 1.4C below average.
Monday arrived with clear skies and sunshine after sunrise at 07.27. A pleasant sunny day is ahead as the anticyclone over Iceland pushes a ridge over the UK. The barometric pressure at 08.00 read 1022.0mb, the highest all month, and currently rising rapidly. The Arctic air stream will be brought on a Northerly breeze today before backing overnight and into tomorrow to come from a westerly quadrant, a slightly less cold direction. However, as the high and low pressure systems relocate, the wind will veer back into the northwest on Wednesday and Thursday feeding down the colder air, Thursday is likely to be the coldest day this week as by Friday the wind is forecast to back into the southwest again, heralding another significant change in our weather pattern.
