Showers arriving tonight, becoming more widespread tomorrow.
This Evening and Tonight:
After a fine end to the day, skies will turn cloudier overnight with the chance of a few showers, possibly heavy. Temperatures will hold up for most and it will begin to feel more humid. Minimum Temperature 12C.
Showery outbreaks of rain will become more widespread through Thursday, particularly in the east with heavy and locally thundery downpours possible. Some brighter spells in the west. Cooler than Wednesday. Maximum Temperature 20C.
Outlook for Friday to Sunday:
Plenty of dry and sunny weather through Friday and the weekend, but also the risk of scattered thunderstorms. Becoming very warm during the day, but with a stiff easterly breeze.
Day 6 to 15
Bank Holiday Monday will be fine and very warm for many, although cooler along some North Sea coasts with mist and fog. Scattered thunderstorms could affect southern and some central areas, but many will remain dry. Very warm and perhaps hot weather will continue for most through the end of May with plenty of sunshine, but with the risk of showers or thunderstorms more widely. With light easterly winds, North Sea coasts will often be cooler and cloudier. Into early June, confidence becomes low but most should remain dry and warm, although probably cooler than at the end of May. However, there will be an increasing chance of somewhat more changeable weather with the risk of showery rain becoming more widespread.
Day 16 to 30
Confidence remains low through June, however there are signs that it may become more widely changeable across the UK. This will bring more frequent spells of rain or showers. However there are likely to be drier and more settled periods for most areas too. Temperatures are likely to be near or slightly above average on the whole, with the potential for some warmer spells, especially at first.
