Metoffice Outlook (although they mention cold spells are still possible.)
UK Outlook for Thursday 21 Feb 2019 to Saturday 2 Mar 2019:
Many places will stay dry with sunny spells on Thursday and Friday. The far west and northwest is likely to be cloudier and breezier, with some rain and drizzle. Temperatures will widely be above the seasonal average, but sometimes they will be tempered in the north and west by the wind. Towards the end of Februarary and beinging of March, there will probably be a good deal of dry and bright weather across the south and east, but morning fog is likely here. It will be more changeable in the northwest, with the risk of gales, although some drier interludes are possible here. Temperatures are most likely to be mild overall, but overnight frosts will be likely, with a small chance of a colder spell developing in the east later.
UK Outlook for Sunday 3 Mar 2019 to Sunday 17 Mar 2019:
For the start of March we are likely to continue to see Atlantic frontal systems mainly affecting northern and western parts, but these will occasionally move further east across the rest of the UK as more active features, with strong winds and rain at times. However, many southern and eastern parts of the UK should remain predominantly settled throughout. Any snow looks most likely to be confined to higher ground in the north, although there remains a small chance of snow to low-levels elsewhere, should a continental easterly airflow develop. Temperatures are likely to remain mild overall, although some night frosts are likley in quieter periods.
