Confidence is high for this period as local high pressure is expected to give a mostly settled outlook, with any uncertainty being associated with the orientation of this high. Current signals suggest a placement over the south of the UK before transferring to the north later next week. Consequently, most areas will stay fine and dry with plenty of sunny spells, with any spells of rain and stronger winds are most likely to occur in the far north and west of the UK where front incursions are most likely. Where skies clear overnight frost and fog patches may become prevalent. Temperatures are likely to remain around average for the time of year, however a short colder spell is likely to occur at the end of next week for a time.

Settled conditions are likely to continue at the start of the period, though Atlantic frontal systems may make more progress across the country at times, introducing occasional wetter weather. This may be associated with around normal to colder than normal conditions for a time. After this however, a trend towards more unsettled conditions through the middle part of March is signalled with spells of rain and showers but with some drier interludes. Rain perhaps becoming more confined to the north and west later with the south and east seeing some more prolonged settled periods. Temperatures are most likely to remain around or a little above average and whilst there are no signals for prolonged cold, some brief colder intervals continue to remain possible.
