TV stations tend to report that 'the weather' is causing reception problems when what they really mean is that 'the high atmospheric pressure leading to the present weather conditions' is the cause.
The atmospheric pressure across the UK is currently at least 1020 hPa, and rising. That's unusually high. Such high pressure in the summer results in very hot weather and then thunderstorms. In mid-winter it will result in bitterly cold conditions, often with severe snow storms. People accept that thunderstorms or snow storms are associated with poor TV reception, even though it's actually the high atmospheric pressure which is the underlying cause.
In autumn, unusually high pressure simply leads to rather pleasant (and unusually mild) weather. It can still cause TV reception problems which, confusingly, broadcasters refer to as 'weather-related', when what they really mean is 'pressure-related'.
