Increasingly warm on Wednesday and Thursday as high pressure continues to build across the country. Plenty of clear, sunny spells with temperatures well above average. Cooler on Friday.

Following a widely fine and very warm spell through the week, temperatures are most likely to return back closer to average from the north during Friday. Whilst a little rain is possible during this transition, most areas remaining largely dry. Largely fine but cooler conditions are then most likely over the weekend. However, likely cloudier and breezier at times across some northern areas with a chance of rain. Into the following week, conditions will probably turn more changeable overall, with dry, settled periods interspersed with some spells of wetter weather. This will bring some showers or longer spells of rain at times, which could be heavy and thundery in places. Temperatures will likely be around average.

Fairly typical spring weather is expected during this part of May. Periods of fine and dry weather are likely to be interspersed with spells of wetter, more unsettled weather, with a risk of heavy rain and thunderstorms in places. Temperatures will most likely be near or slightly above average overall.
