    I've been wondering about this for a while, can someone explain what the solid green line signifies.

    Red is 30 year avg
    Blue is the control run of the ensembles
    Green is the GFS forecast run.
    Grey is ensemble avg for this time of the year.

    850mb temps in celcius.In other words if we have -10c 850mb temps above us,the temp at ground level would be close to 0c.

    Thanks Snowbie, any idea what the difference is between the control run and the forecast run?

    The green is the GFS operational forecast run and the blue control run would be data from all ensembles giving an average control run.

    So Green would be GFS forecasting conditions in this case 850 temps for the near future(this changes quite alot)

    Blue would be inline with most ensembles to give a more accurate look out.

    I mightened be 100% on all this but i think im close.
