It’s a hard thing to do.
The other week, as there’s a long weekend coming up, I booked a camping holiday, in Wales. Only a day or two later, the news outlets started running stories about how awful the Easter weekend weather was going to be; wind, rain, sleet and snow. Oh dear.
There’s still snow on the forecast for Northumbria; but the forecast for the Welsh weather, though, has got noticeably better over the past few days. It’s gone from sleet, to showers, to sunny periods. And I’ve noticed this happening before. There seems to be a tendency now for the forecasts to be more extreme further off, before calming down as the date approaches.
Which is statistically what you’d expect, of course. Extreme weather is, by definition, unlikely, and shorter-range forecasts are always more accurate, so any extreme weather in a long-range forecast is likely to mellow as the forecast gets closer. That doesn’t stop the news jumping on any forecasts of horrible blizzards, though. I’m still worried that the snow forecast for the north Pennines is going to creep southwards over the weekend.
