Planning Outlook
High pressure remains dominant this weekend and into next week: regularly sunny and pleasantly warm days; summit temperatures often at or above 10C, many valleys will warm up toward 20C afternoon. Risk of sunburn in strong sunshine and very dry springtime ground conditions with high risk of wildfire. Risk of showers Sunday and Monday, which could be heavy Monday, some risk of thunderstorms developing in England, though confidence is low. The middle of next week remains settled with sunshine, patchy dawn mist that soon fades. An easterly wind establishes in Wales from mid-week, then a rising risk of wind pushing northward with rain following. Long-term detail is very uncertain, but a trend towards cooler, more unsettled weather is indicated in early May.
