Largely cloudy today with a little rain.

Today:

Skies will be on the cloudy side today with outbreaks of light rain and drizzle at times. However, it is likely to be drier for a time around noon with some bright spells possible. Maximum Temperature 13C.

Tonight:

Low cloud will spread in tonight bringing mist and murk over the hills. Outbreaks of rain and drizzle will continue, mainly over over the hills and around coasts. Minimum Temperature 7C.

Wednesday:

Most places will be dry by Wednesday morning. The cloud will gradually break up through the morning to give some warm sunny spells in places, especially in the east. Maximum Temperature 16C.

Outlook for Thursday to Saturday:

Thursday and Friday should be largely dry and cloudy, but some bright spells are possible. A band of rain gradually sinks south through Saturday, followed by cooler and showery weather.

Day 6 to 15

Confidence is low for this weekend, but it looks sunny for many, once patchy rain in the south clears. There will be some blustery showers in the northwest though, with the risk of gales in the far north. Through the latter stages of March, we will see a good deal of dry weather across central and southeastern parts of the UK, with bright or sunny spells. It will be more changeable across the northwest, with rain and strong winds from time to time. Temperatures are most likely to be around the average for the time of year, although some warmer periods are likely in the southeast when the sun shines. However, occasionally in the northwest it may be rather cold.

Day 16 to 30

For the start of April, changeable conditions are likely, with near normal temperatures across the UK. Thereafter, the forecast looks more uncertain, but it seems most likely that we will see changeable conditions across the UK once again. Wet and windy weather may be interspersed with drier and brighter spells, with the most unsettled conditions still probable in the north. By the middle of the month, we may see a return of more widely settled weather. Temperatures could potentially start off a little warmer than average, but they may fall nearer to the seasonal average for a time in early April.
