After hot and dry weather in parts of the country, much of the UK faces a cooler and more unsettled week as rain, sunshine and showers continue across the country.The Met Office says Monday will start with rain and wind in many areas, especially in England and Wales, before conditions gradually improve from the west. However, the improvement is unlikely to last long, with widespread rainfall expected across the UK in the coming days.Forecasters said the rain would continue to move south-eastwards throughout the day, tapering off gradually in the afternoon and evening.The day started with sunshine and persistent rain over Northern Ireland and Scotland and this pattern of rain is expected to spread to many other parts of the UK by the end of the day.The Met Office said temperatures in early June will be below normal expectations for many people, with strong winds making many areas feel cooler.Travelers in parts of southern England may experience difficult traveling conditions during heavy rain, while outdoor events may be disrupted due to rain.Conditions are expected to remain dry for a short time across much of England and Wales during Monday evening as the main rain bands finally clear.However, forecasters warned that rain would continue across Northern Ireland and Scotland before spreading southwards to other parts of the country overnight.Where skies remain clear for extended periods, temperatures may drop significantly, leading to fairly cool nights by June standards. Rural areas and sheltered locations are likely to experience the coldest conditions before dawn.The classic mix of early summer sunshine and rain is expected across Britain on Tuesday.There will be bright sunshine during the day in many areas, but widespread rainfall is expected, particularly across northern England, Scotland and Northern Ireland.The Met Office says some of this rainfall could be heavy and stormy, causing intense rain and strong winds.Despite the sunshine, temperatures are expected to remain cool at this time of year, with many places struggling to recover the heat seen in recent weeks.The broad outlook suggests little change in the middle and latter half of the week.More sunshine and rain is expected in many areas on Wednesday. Another area of rain is forecast to move eastwards across the country on Thursday, clearing with a chance of sunshine and scattered showers on Friday.While much of the UK will remain cooler than average, the far south-east of England could see slightly warmer conditions by the end of the week.The overall message from the Met Office is that weather patterns in the UK will continue to change and there is currently no sign of long-term stability in summer weather.For those planning travel, outdoor activities or sporting events, it would be wise to have an umbrella with you and check local forecasts regularly as conditions change from day to day.
