    I just found that you can stop the animation on the earthnullschool maps which makes for a less cluttered map. Click on the triangle next to Grid.

    Incredibly beautiful clear skies today in N.E Australia not a contrail to be seen.

    You need to do a conversion for your local time. z is Zulu time which is the same as GMT (Greenwich Mean Time) so the latest on there at the moment is midnight GMT last night (2016-07-08 00Z). To look at the RH for this morning in the UK I would select 9h to give me 09:00 GMT (midnight plus nine hours).

    Of course this is further complicated by daylight saving time so a further calculation is needed for British Summer Time (BST)

    Hope that makes sense

    No for midnight UK pick 00z and 0h (midnight plus 0 hours). Selecting 9h would give you 9am the next day

    Choose the most recent run. The weather model runs four times a day, at 00Z, 06Z, 12Z and 18Z: that's midnight, 6am, noon and 6pm Greenwich Mean Time. They take a few hours to appear on the site after the quoted run time though.

    The model runs in 3 hourly steps. Right now it is just after 5pm GMT (17Z). The most recent run available is the 12Z, which is 5 hours ago, so I would choose that and then look at the 6h chart (six hours after the model run). The time on that chart is 18Z today, which is in just less than an hour's time.

    Alternatively if you wanted to see a chart for, say, 6pm yesterday you could choose the July 7 18Z model run and select the 0h chart.
