This Evening and Tonight:

A wet end to the day with heavy rain or showers. This persisting throughout much of the night before gradually clearing eastwards for most by dawn. Turning chilly in the countryside with isolated fog patches. Minimum temperature 2 °C.

Saturday:

A damp morning in the east with rain easing. Sunny spells through the afternoon with cloud thickening from the west later with freshening winds later. Feeling less mild. Maximum temperature 10 °C.

Outlook for Sunday to Tuesday:

Wetter and windier on Sunday with occasional drizzly rain, this most frequent over the hills. Showery rain still possible on Monday. Drier and brighter on Tuesday. Staying mild.

Much of this period looks like being largely dominated by high pressure, especially towards the south or southeast of the UK. This will mean many places seeing plenty of dry weather with variable cloud amounts and some sunshine, the best of this towards the south or southeast, but perhaps with some fog overnight. However, frontal systems are still likely to affect the north and west of the UK at times though, maybe also briefly affecting other parts, bringing some rain and strong winds, and perhaps a little snow to the high ground in the north. Temperatures will be near or above normal, although patchy overnight frost is still likely at times.

Little change at first, probably most unsettled in the west and northwest but drier and brighter toward the east and southeast. Lower confidence late-March but perhaps a trend toward more blocked and slow-moving weather patterns, although uncertain whether this will lead to cyclonic and so more unsettled weather or anti-cyclonic, more settled and maybe colder patterns in the vicinity of the UK. In general, some rain still probable but distribution of any wetter areas is extremely low confidence. Temperatures overall near or above average, perhaps with a slightly increasing chance this may trend colder toward the end of the month.
