Wales will experience a “brief taste of summer” this week before stronger winds, rain and showers move for the weekend.
But it won’t last long either, as low pressure looks set to be replaced by high pressure during the last week of the month.
Spring in Wales is one of the driest ever recorded with very little rain and temperatures this week could reach 26 ° C by Wednesday and 28 ° C in other parts of the United Kingdom.
Parts of the UK will be warmer than some of Europe’s top tourist destinations, including Marbella and Ibiza.
There is a possibility of thunder and rain bands across the south and east of England and Wales on Thursday while Friday could be windy, mainly for the western areas, with heavy downpours.
Welsh meteorologist Derek Brockway said: “A brief glimpse of summer in the coming week. Wednesday is the warmest and sunniest day in Wales.
“Cooler and potentially unstable later in the week and next weekend with stronger winds, rain and showers. Low pressure could be replaced by high pressure during the last week of the month.”
Meteorologists are keeping an eye on the tropical storm Arthur that formed in the Atlantic off the southeastern coast of the United States to see what impact it will have on the UK at the end of the week.
BBC Breakfast forecaster Matt Taylor said: “We are ready to see a very hot climate before things start to get cooler and windy.
“How beautiful it is, how windy it is, a little uncertain at the beginning of the week and this is because what is happening in the western Atlantic.
“We have our first named Atlantic storm of the season, just north of the Bahamas, flying away.
“This will stir up some atmosphere and provide some question marks for our proceedings later in the week. Before getting there, the light air will be with us at temperatures above the levels it should be for the time of year .
“The real hot spell comes mid-week as we have a high pressure area that is destined to develop across the UK and means that we will be drawing air from the nearby continent. Temperatures will increase widely in the UK with the hottest of the year till now.”
