UAV Forecast app questions

Hi

As just posted on Drone discussion I now have my Mavic 2 Pro and its all charged and updated & ready to fly. I have just looked at the UAV Forecast app and the headline says ‘Not Good To Fly’. Looking at the forecast page its all green except for 81% cloud cover, its showing 14 visible sats, 11mph wind gusting to 20mph and a temperature of 8c. Would cloud cover affect flight, especially as I am currently using beginner mode and the cloud base looks well over 1000 ft (based on looking at commercial airliners taking off and comparing that to the data shown in Flight Radar).

Thanks
