I doubt if you’ll ever see a temperature forecast as way out as this one got. It was issued by the Met OfficeUKMO The Meteorological Office is the United Kingdom's national weather service. It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy in their weather app on the 5th of January for Altnaharra in Sutherland. The blue line in the top chart shows three hourly forecast temperatures for the next seven days. The red filled area shows air temperatures taken from AWSAWS Automatic Weather Station observations for Altnaharra. The lower bar chart, shows the difference between the forecast and the observed. Although the forecast for the 7th to the 9th was reasonably accurate, the 10th and 11th got progressively worse, with forecast temperatures being as much as 20°C too high at one point. I’m not sure what NWPNWP Numerical weather prediction uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. model the Met Office use for these site specific forecasts, but it has got some severe problems, and not just with record cold temperatures I might add.
