A detailed forecast of what's to come today and tomorrow, for regions, towns and cities describing the expected weather, temperatures and wind speeds along with detailed and timely warnings of severe weather.

A general picture of the weather on a day-by-day basis, with the main regional variations identified. We have a good track record in advising on any significant risk of severe weather in this period.
A broad description of the weather likely to be affecting the UK, including significant changes in the type of weather. We'll also give a risk assessment of severe weather, such as heavy rainfall, severe gales or an extended period of high or low temperatures.

These give an indication of the most likely predominant weather conditions for that location for the time specified. For example, if our forecasts models predict sunny intervals with just a small chan...

Nov 15, 2023 · Forecasting uncertainty. Despite the certainty suggested in some online headlines, meteorology isn’t an exact science, and although forecast accuracy is improving (the Met Office’s 4-day forecast is as accurate as its 1-day forecast was 30 years ago), long range predictions come with in-built uncertainty.
