When I did PPL flying I often backed up the met office forecast,with a look at the TV.Usually BBC Scotland as they were pretty good.It was noticeable that you could often get 2 very different forecasts,but they came from the same source.I would take the worst case one.
My IMC flying instructor used to say that IMC rated pilots should practise on Flight Sim on the computer.It keeps you current at little cost and is very realistic.Also if you get it wrong,you live!
Real IMC conditions for an inexperienced pilot is very frightening,and dangerous.Look at JFK jnr
