The nights are ‘drawing in’, Autumn (fall) starts officially on Wednesday this week. The weather is set to get colder. There will be a change to it, mist and fogs are due, rain and wind, even some storms.
This photo was taken a few nights ago, high pressure over the UK and a red sky in the evening indicating settled warm weather.
Even if we had long term weather forecasts they are never that accurate here in the UK. The air over us is unstable, affected by the ocean, the Arctic, weather over Europe and coming in from the East over Russia. If you want interesting, rapidly changing weather come to the UK.
