It will be changeable through the coming week with the most disturbed weather in the second half, and there will be some wintriness over high ground, mainly in northern areas, long range weather forecasts. Through the first half of March more settled conditions should develop, especially during the second week, as high pressure makes more of an appearance.

Our extended-range forecasts provide an overview of potential weather conditions up to 46 days ahead, focussing mainly on average conditions week by week and how different they are from a long-term model-based climatology. For example, charts show if the average conditions over a week are predicted to be colder or warmer than normal for that time of year. The extended-range forecasts are produced daily and have a horizontal resolution of around 36 km. Find out more about how the extended-range forecast is produced. The state of the oceans and the top part of the Earth's land masses can vary relatively slowly, providing a potential source of predictability in the extended range through their interaction with the atmosphere. Variations in the stratosphere may also play a role.

This sets the scene for the following days as spells of rain are expected across all areas at times between brief settled spells, wettest overall in the west and northwest, where it will also sometimes be windy. Late in the period more settled conditions develop in the east as rain occasionally runs across western areas in a more southerly wind direction.

When looking at forecasts beyond five days into the future the chaotic nature of the atmosphere starts to come into play - small events currently over the Atlantic can have potentially significant impacts on our weather in the UK in several days' time. Therefore whilst we can still forecast the general feel of the weather to a relatively high level of accuracy using our ensemble models, it becomes harder to offer local detail to as high a level of accuracy as our shorter range forecasts. For this reason our text forecasts for 5 days and beyond are written on the scale of the UK as a whole.
