My take on the weather of the last 20 years here in Bristol is that generally late summer/autumn has been 'longer' than in my childhood and early 20s i.e. warmth lasting past what i once knew as 'end of summer' ; winters have been 'shorter', mild, v.little snow. The period 78 -87 produced some great winters, with plenty of snow. However, the 70s mainly had mild, wet winters. I've read press archives going back 100 years+ into the 1800s and there were definitely more snow events in my neck of the woods. In fact, one aspect of our winter weather that has but all disappeared is the 'winter channel low'. This used to turn up in southern england at least once in most winters and a number of press articles indicate it turned up at least 3 times some winters giving us southerners raging blizzards! It does appear that there's been a change in the last 20 years, but could it just be part of a global cycle? Maybe we will gradually return to a more snowy winter environment in the coming years.
