Headline:

Rain clearing on Wednesday.

This Evening and Tonight:

A band of heavy rain will move east across all areas before midnight, clearing to clear spells and sharp showers through the early hours. Gusty winds, these easing before dawn. Milder than Monday night. Minimum temperature 5 °C.

Wednesday:

A cloudy start for many on Wednesday with further spells of rain or sharp showers, these soon clearing with sunny spells developing into the afternoon. Feeling warm in the sunshine. Maximum temperature 16 °C.

Outlook for Thursday to Saturday:

Largely settled on Thursday with variable amounts of cloud and a few showers. Turning increasingly cloudy from Friday, as rain moves slowly but erratically in from the west. Normal temperatures.

Starting off with something of a northwest to southeast split; higher pressure located towards the southeast should bring fine and increasingly warm conditions across at least southern UK, whilst there is a greater chance of periods of cloud, rain and stronger winds affecting the north. There will be fine weather here at times as well too however. There's a small chance that fine and very warm weather could extend right across the country early next week, but it's more likely that cloud/rain in the northwest will sink southeast introducing more changeable and cooler conditions for a time mid-week. It then becomes roughly equal chances that we see a resumption of mainly fine and dry conditions versus a continuation of more changeable weather with a mixture of rain and drier interludes.

Forecast confidence is lower than average for this range, although fairly typical for late Spring. A typical mixture of drier and settled periods, and periods of wetter and more unsettled conditions, is on balance slightly more likely than predominantly unsettled or predominantly settled. Temperatures are likely to be around average overall, with a slightly increased chance of warm or hot spells. Any such spells could be accompanied by locally heavy showers and thunderstorms.
