We are certainly back to normality after the upper 50s to near 70s across much of the UK to end October. Yesterday Britain’s warmest was only 12C or 55F. Much closer to normal for this time of year.
What I find interesting is that when we manage to get a small bubble of high pressure that is squeezed in between the “train cars” of low pressure that run along the up and down Atlantic jet stream, we get settled weather with sunshine, light winds and right now the air is relatively dry (british standards), when you get that we tend to see chilly, frosty mornings but as soon as the sun’s up the temperature rises rapidly, I saw within about an hour or hour and a half, the temperature rise from 32F to 37 as the incoming solar energy rapidly warms a reasonably dry air mass. We hit 51 degrees and now that the increasingly lower angled sun drops so too does the temperature, only about 30 minutes ago it was 44 degrees and now it’s 42.6 degrees and dropping.
This morning’s national low was likely around 21 degrees F/-6C in the typical cold spots of the Scottish Highlands, yesterday’s low was 25 degrees -4C and when I left Glasgow yesterday morning it was around 3 or 4C (upper 30s to around 40F) only to find when I drove southbound on the M74 and into southwest Scotland the skies were clear and the temperature was at or slightly below freezing as cars were white with frost around the Dumfries and Thornhill area of southwestern Scotland.
I predict a low tonight here at the house of around 28 degrees if the skies remain mostly clear and winds remain light to calm. As we progress into mid-November it is becoming increasingly easier for any clearly of skies for the temperature to drop fast and frost to form. Even when heading for bed and it’s raining outside, even with just a couple of hours of clearin skies in all that’s need this tiome of year for wet ground and raindrops on your windshield to turn to ice. We have so much longer hours of darkness now and with less daytime solar imput from the lower angled sun which means the ability for the sun to warm the ground and then heat the air is much more difficult.
In saying all this, we are still fairly mild for the time of year and I still stand firm in my idea that we have a mild period throughout November before the onslaught to a much colder time ahead. Even with possibly snowshowers and frosty nights, we shall remain mild compared to what I believe is on the way leading up to Christmas..
Thanks for reading.
