    Best mid-range forecast?

    Would anyone be able to recommend - or share their own practice - solutions for mid-term weather and forecasting?

    TAFs are obviously ultra-short-term, but I find the Met Office/BBC just isnít useful beyond 24 hours.

    I sometimes look at Windfinder, but I find this tends to over-estimate wind speed considerably.

    It would be great to know if there are any providers or sources that can help, looking 24hrs > 5 days ahead. I ask only because I have to book time off work for lessons, but if the weather is iffy Iíve wasted annual leave if I donít fly - and I need to give the club more than 24 hours notice if I change dates/times.

    Being able to look more than 24 hours ahead would be really useful but I canít find anything even half reliable (knowing that weather is an inexact science); yesterday BBC was saying tomorrow is dry and sunny, this morning itís saying wet and cloudy!

    Or - is the answer: donít try thinking about weather more than 24 hours in advance?

    I use this to guide how much the others can be trusted:

    24 hour to 5 days out is the most difficult for any forecasting model, at least to the level of detail that we need. So yes, accept that 24 hours is about all that's possible with the precision and reliability needed to know whether to go to the airfield or not. Longer than 5 days can be quite accurate at least in terms of overall trends.

    Lots of research money being spent at the moment on improving medium term forecast models (not that that helps us just now!).

    Simon Keeling's twice weekly videos are pretty good, and he will sometimes comment on the confidence level, which is helpful (different weather patterns have different levels of predictabiliy).

    Incidentally in my recent experience the BBC is rubbish. The Met Office is much better for the short and medium term. The BBC get their forecasts from a different source these days, having ditched the met office because they were too expensive.

    You need also to be getting familiar with the aviation forecasts that the Met Office produce. Search their site for it - you need to register, but it's free.

    It's worth perseverance to learn about the weather - you will get the feel for it in time. And it's easier in the summer generally.

    I'll second Windy and especially Simon Keeling's forecasts. Both are good for the time period you are interested in. I'd also recommend a good look round Simon's website:

    Edit: Simon's forecasts are on Thurdsays around about noon and Tuesdays (I think).

    I find Windy very useful for 48 hours or so, the met office very good for tomorrow and a mixture of looking out the window, TAFs, METARs (windy is quite good for looking at lots of those at once and it translates them) and meteoradar for right now/the next few hours.

    A very useful thing about Windy is that it tells you how old the forecast you're looking at is, typically it updates at 9am and 9pm. If the weather is changing quickly it can be very inaccurate by mid afternoon.

    Apart from thermal winds in the summer time, I find this the best way to get a general feel for the trend over the next few days. After using it a few times you get an idea what to expect.
