Fri 12th Aug/clouds

Hey as the perseid meteor shower peaks on fri 12th Aug my local astronomy society will be holding a starBBQ. There has been many mixed reports of weather forecasts from 100% cloud till 26%. Can someone find a accurate forecast for fri evening apart from bbc/met office/met check as i find them to be of low standards to cloud forecast.

                     Thanks
