GATES OPENING Still a very wet Sunday, and Monday night into Tuesday, in store in this run. In fact the 06Z appears to put more rain on the site, especially on the Sunday. The latest chart is on the right, previous on the left. This is Sunday. Tuesday is an improvement on the last run, with less rain, but still some rain nonetheless. By Wednesday at 9am, there's some very light rain around. And unfortunately things do not improve from here. Wednesday is showing as having showers - this is not heavy rain - but certainly a downgrade on the last run. Highs of just 18. This is being caused by a small green area of low pressure to the north of England. You can see the difference in the runs here, latest on the right. But how will it develop? THURSDAY The high pressure begins to build in now, making Thursday a largely dry day with small showers around 6pm. However, highs are of just 18. FRIDAY The high pressure finally tries to build in today, but it doesn't prevent it being another day of light showers. High temps of 19. SATURDAY Unfortunately the high is pushed back by an area of lower pressure, meaning we don't get the weekend boost we've had in recent runs. Yet more rain through the day, though clearing in the evening. Highs of just 17 now. SUNDAY Dry, but max temps of 13. This doesn't make sense with the pressure around the UK so seems to be unreliable. SUMMARY Well, we're well and truly back on the rollercoaster. The area of low pressure on the Wednesday makes the start of the festival damp, and the high never pulls in - so there's rain through the main festival too. Temps not getting to 20 will make it a chilly festival, especially on the evenings. However, this doesn't really seem to be a reliable run with what is shown for Sunday. Definitely a downgrade, but it's still TOO EARLY. Huge amount of uncertainty. See you in 6 hours. Quote Link to comment Share on other sites More sharing options...

There's precisely Zero point in trying to rush to the weather reports now, it's still a week away and particularly the main run will vary wildly every 6 hours. Save yourselves the stress and at least wait until we have ensembles. So far the models all suggest the same - some drop in pressure tues/weds/thurs then rising. That's all we know for sure at this range. Quote Link to comment Share on other sites More sharing options...

2019 Posted June 14, 2023 Report Share Posted June 14, 2023 (edited) My current take. GSF and ECMWF agree. Wed 21st/Thur 22nd/Fri 23rd look ok. Dry, day/20c night/15c. A little windy. Sat 24th & Sun 25th 50/50 rain. This is a best guess, as I don't have any data, only charts. ICON13 comes in to play for Wednesday 21st from tomorrow, and should start to reinforce the probability.

Sheffield Steve Posted June 14, 2023 Report Share Posted June 14, 2023 Well we can assume the GFS 6z is outlier but what a shocker it is. It still brings the thundery downpours up from the south on Sunday, and then again on Monday night, which would make the site very wet. Then on Tuesday night, just before gates open it brings in the sort of depression you’d expect to see in winter. There would be strong winds and plenty of heavy rain associated with that. The GFS is known for over-deepening areas of low pressure though, so we need to hope it’s done the same here. It would leave us with a windy (hang on to your tent) and very showery set up day. Another batch of heavy rain close by for Thursday night. More showers on Friday and then more persistent rain on Saturday from yet another area of low pressure developing in the North Sea, which it then has the audacity to bring in from the east over the U.K. to bring more rain on Sunday. It’s been consistent with the thundery rain early next week but is undoubtedly overplaying the rain later on, so let’s pretend this one hasn’t happened and move on to the next… 1 Quote Link to comment Share on other sites More sharing options...

Sheffield Steve Posted June 14, 2023 Report Share Posted June 14, 2023 (edited) The ECMWF now stretches as far as midnight festival Saturday. It is fortunately much drier than the GFS, but still brings us some rain. It has the thundery rain come up on Sunday night like the GFS but sends Tuesdays heavy rain to the east of the U.K. unlike the GFS. It has showers around Wednesday, Thursday and Friday but nothing calamitous. Let’s hope the ECMWF is more accurate than the GFS (quite likely). (ignore the glitch in the middle of the gif, caused by a hole in the space time continuum) Edited June 14, 2023 by Sheffield Steve Quote Link to comment Share on other sites More sharing options...
