    On a recent walk in the hills my day started like this DSC_0717.JPG

    The relative humidity chart from InstantWeatherMaps.com shows around 50% RH at 300mb. The red dot is my approximate location.

    By the end of my walk the skies looked like this

    The relative humidity chart from InstantWeatherMaps.com shows greater than 90% RH at 300mb.

    But to my frustration SQ297 seem not to follow the same flight path each day and can travel over head 1000 clicks north of me or as today just beyond my sight yet for a few days over 2 weeks it went right over head

    chugging along nicely 37000FL I still wonder why/how the same flight can go 1000 clicks to my north yet still aim at fuel efficiently at Christchurch,,, ? upper jet stream winds im suspecting
