For us down here in North Somerset this last week has to be the most problematic period of weather in terms of forecast v outcomes that I recall in the modern tech age. These summaries are based on local forecasts issued after the 6.00PM news on the preceding day.
Forecast for Tuesday: Mainly Sunny, dry. Outcome: Mainly cloudy, dry, and subsequently cooler than forecast.
Forecast for Wednesday: Cloudier, dry. Outcome: Sunnier, dry.
Forecast for Thursday: Cloudy, heavy thundery rain, torrential downpours and storms moving in early and again later. Outcome: Cloudy mainly dry, a few very short periods of very light rain. (Downpours were predicted to be hit or miss but the nearest storm to here missed by eighty miles or so!)
Forecast for Friday: Rain in the morning, clearing to brighter spells and drier during the afternoon. Outcome: Rain in the morning, slowly easing but staying cloudy until evening.
This is not meant to be a criticism of an excellent service but more a 'what the hells going on this summer that is making forecasting so difficult' as there have been many other instances of this in the last few months.
Normally the forecasting is boringly accurate! It does however make me love the weather even more. A fool and a fickle woman.........
