Twenty day weather forecast

The extended range forecast, which includes the monthly and seasonal forecasts, can at times provide an insight into weather patterns in the months ahead. However, they should not be used for specific planning purposes as they have generally low skill compared with the day forecast. This is because forecasts beyond one week become increasingly uncertain due to the chaotic nature of the atmosphere. Further information can be found here Monthly and seasonal forecast explained. Week 1 will be largely unsettled with low pressure systems often tracking close to Ireland. A predominantly westerly airflow will steer frontal systems across the country at times, with rainfall amounts expected to be above average for most of the country. Rainfall will be closer to normal in southern coastal areas. Mean temperatures will be around normal, possibly slightly warmer than average in some western coastal areas. There is a trend towards more settled conditions in Week 2 as low pressure weakens and high pressure begins to have more of an influence on our weather. While occasional showers and spells of rain are likely, rainfall amounts will be lower than normal for most of the country. Coastal regions of the west will be the exception, with near average rainfall there.

Expect some windy days in the mix too.

Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere, land, and ocean and using meteorology to project how the atmosphere will change at a given place. Once calculated manually based mainly upon changes in barometric pressure , current weather conditions, and sky conditions or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account. The inaccuracy of forecasting is due to the chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, the land, and the ocean, the error involved in measuring the initial conditions, and an incomplete understanding of atmospheric and related processes. Hence, forecasts become less accurate as the difference between the current time and the time for which the forecast is being made the range of the forecast increases.
