Do you have the same issue if you follow the OP’s steps to reproduce it?
Provide your location and time (UTC):
EIDW 2030 UTC
If relevant, provide additional screenshots/video (METAR if available):
Please see in the link a video of the bug in action at EIDW, as you can see the clouds are present (although not correct still) then after some time they begin to clear and disappear when this location should be thick cloud.
This is what we are observing also at other locations we have tested:
I took some videos over the course of more than 1 hour at EIDW today. I combined them and ramped the speed up to approx. 30 times.
Initally there was no cloud coverage over entire Ireland, apart from some singular ones up north, which dissolved over time. FEW014, FEW020CB and BKN060 weren’t displayed, the same goes for the convective clouds all over the isöand discernable on the satellite imagery.
The 1530Z METAR contained TS and visibilty 6000, and that seemed to trigger the formation of clouds and a visibilty bubble. The visibility bubble was limited to the EIDW area, clouds were forming all over the place, but to the largest extent directly around EIDW.
Obviously, these clouds and the visibilty bubble started to dissolve over time, and when the 1600Z METAR came in, they were practically gone and the whole Island had clear skies again, despite the satellite imagery still showing convective clouds all over Ireland and the METAR from 1600Z had -SHRA, FEW012, SCT020CB and BKN 038.
I can only guess what that means, but there’s clearly something going on that needs the devs attention.
I noticed a pattern with the Live weather, which is reproducible every hour.
Around 40-45 minutes after the hour, e.g. 10:40-10:45UTC, the weather is loaded in as it should be.
Then from 45-50 onwards e.g. 10:50UTC the clouds start to disappear again and be removed, this happens for the next 30-40 minutes until then around 40-45 past the hour, they inject again, then begin to be removed again.
Additional findings regarding the situation above:
London is at the edge of the cloud system when it was depicted correctly.
When taking the screenshot 1110Z I watched for some time, and that cloud coverage was developing, most probably until it reached the state documented in the 1126Z screenshot. So I think it is fair to assume that between 1102Z and 1106Z a different data set was injected so that the weather depiction at EGLC developed into something reasonable.
I didn’t follow the situation continously, because at 1118Z I checked EGHI, which is well beneath the cloud coverage and found it to be accurate.

Yes

Yep, it’s stuck in a constant loop which you can observe every hour, as demonstrated in the screenshots below.
Weather loads in fully by around 35-45 minutes past the hour, then begins to unload again, then next hour loads in again by 35-45 minutes past the hour and round and round it goes.
