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, near normal, and above normal.

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.

This is because forecasts beyond one week become increasingly uncertain due to the chaotic nature of the atmosphere. No warnings in place for Hamilton.

A dry start to this period is most likely in the south of the UK, with some night-time frost and perhaps patchy fog, but rain will already by making its way into northern parts of the UK on Tuesday, spreading south. This sets the scene for a generally unsettled pattern that is likely to continue through to early March. Spells of rain are expected across all areas at times, wettest overall in the west and northwest, where it will also sometimes be windy. Temperatures are most likely to be around or a little above average, though some short-lived colder interludes that would allow sleet or snow to fall to lower levels are possible at times, these more likely in the north. An initial continuation of unsettled conditions is most likely in this period, with low pressure systems continuing to cross west to east over or close to the UK, with mostly short-lived spells of drier and brighter weather between times.

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. Forecasts based on temperature and precipitation are important to agriculture, and therefore to traders within commodity markets.

The rainfall forecast is less certain, with the likelihood of slightly wetter than average conditions overall, though there is the potential for drier spells in March and May in particular. 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. Moonset am. 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.

The second half of the month should see regular fluctuations with plenty of warm days still, but interspersed with cooler outbreaks, before an overall downwards trend towards the tail end of summer.
