(Going on holiday to Devon this Saturday so if anyone's got any other forecasts for the next 2 weeks, I'd be grateful!)
TheWeatherOutlook says this for the next 2 weeks:
15/4 to 21/4
A mostly dry start to the week is expected, with temperatures slightly above the seasonal average. Through the week there may a change to less settled weather, with an increasing risk of showers or longer spells of rain in the north, possibly extending further south.
22/4 to 30/4
Close to average conditions in the north with showers or longer spells of rain at times. In the south there should be a fair amount of dry weather, but perhaps with an increasing risk of heavy showers. Temperatures in the south possibly remaining above average.
