Twenty day weather forecast

These include day outlooks, monthly outlooks, and seasonal outlooks. Unlike regular "zone forecasts" issued by a local National Weather Service office, the climatological outlooks provide probability forecasts for both temperature and precipitation, divided into tercile groups: below normal, twenty day weather forecast, near normal, and above normal. For information about how to read the latest 8 to 14 day outlooks, for example, click here. Latest Day Precipitation Outlook.

Hot days and muggy nights, alongside plenty of dry weather this January, has seen soils rapidly dry out in the east from Wairarapa to North Canterbury, as well as about South Taranaki, Auckland and Northland. Further south, eastern parts of South Canterbury, Otago and Southland remain dry, but closer to normal, with fronts during the second half of the month providing useful top-ups. Meanwhile, soil moisture levels were kept above normal across much of Gisborne and Hawkes Bay with persistent southeasterlies offering a very wet final few days of the month, these regions continuing to avoid any drought concerns for the time-being. The central North Island has been wetter than normal due to a couple sub-tropical rainfall events on the 15th and 28th, despite numerous sunny, dry days here too.

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.

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. The use of ensembles and model consensus helps narrow the error and provide confidence in the forecast. There is a vast variety of end uses for weather forecasts. Weather warnings are important because they are used to protect lives and property.
