steviewevie Posted June 14, 2022 Report Share Posted June 14, 2022 5 minutes ago, Aragorn said: Here are the ensembles overnight that show precipitation. The green operational run is what bridjj posts on here by way of charts. The red run is the average of all 20 runs. The blue run is the control run. As you can see gfs again shows minimal rain across its various runs. For me though the more reliable models UKMO AND EMCWF are not quite so bullish and there is a chance low pressure will force out the high somewhat. One to watch very closely. What is control and what is operational? Quote Link to comment Share on other sites More sharing options...

Control run is abit like the line on a covid test that shows whether test is dodgy or not. Operational run is the main run that is used for the model output. So when you those charts posted on here - red high pressure and rain maps etc they are based on the operational run. Supposed to be the most accurate run Quote Link to comment Share on other sites More sharing options...

The 500 + SLP looks a bit odd to me though, and after all of those runs yesterday, this one is very different. So not too concerning yet.

The flooding did drain and by saturday evening most of the mud had gone (I think) Quote Link to comment Share on other sites More sharing options...
Aragorn Posted June 14, 2022 Report Share Posted June 14, 2022 The UKMO AND ECMWF are not great but quite different with no real agreement. Both show low pressure on or around the UK. Still alot of time for things to change in weather terms. 1 Quote Link to comment Share on other sites More sharing options...

Definitely 6 minutes ago, Aragorn said: The UKMO AND ECMWF are not great but quite different with no real agreement. Both show low pressure on or around the UK. Still alot of time for things to change in weather terms. The ECMWF only goes up to Thursday. It's highly considered to be the best. And it has been improving every run, (you've posted images of an older run) with the only rain now showing between now and Thursday being this Sunday coming... It's looking good so far 🤞 (Don't forget the ECMWF precipitation model shows total rain up to and including each time slot, not rain during that time slot, if that makes sense.)

Aragorn Posted June 14, 2022 Report Share Posted June 14, 2022 The GFS whilst a good indicator is the least accurate of the UKMO, ECMWF and GFS. So I'm inclined to look towards the euro models now. That said that ECMWF chart has not updated yet for last night 00z so could be alot different. Quote Link to comment Share on other sites More sharing options...

Spot on, the ECMWF is considered to be the best, but it is shorter range. It updated for the 12z yesterday, which was better than the 00z images you posted earlier 🙂 Quote Link to comment Share on other sites More sharing options...

FRIDAY Totally dry, and back to 24 degrees. The high pressure has actually consolidated its position and got stronger. SATURDAY Yep, another lovely dry day but temps drop a little to 20 as the low tries to muscle in. The low pressure has decided to fight back from the north, but how far can it push? The high is staying strong, leaving the low our east. SUNDAY Dry, dry, dry. Temps back up to 23. Lovely. The high pressure wins AGAIN! Moving back in with the low sent packing. SUMMARY The 18z, that we all hated so much, has delivered the best charts yet. But it's TOO EARLY. That low pressure to the north and east (and to an extent the pocked to the south which could bring rain) remains a real danger and it could still all go wrong.

briddj Posted June 14, 2022 Report Share Posted June 14, 2022 Will the 00Z continue on the shock positive theme of the 18Z? Let's find out! THIS WEEKEND It's a bad start, with lots of heavy rain in a band across the south west on Sunday. But this is really only just touching the site on this run. But it is there nonetheless. It is then completely dry to gates open. But what happens with the high this time? Again, the high builds in as the festival begins. GATES OPEN It means it's still great for gates open. 19 and dry. THE FIRST DAYS WEDNESDAY Completely dry, 23 degress. But the low pressure is starting to build in from the north east. THURSDAY Dry but a little cooler, at 19 degrees. That's due to the increasing influence of the low. But who will win the fight in this run? THE FESTIVAL PROPER FRIDAY Completely dry, 20 degrees. The low pressure appears to be winning the fight now, what will it do to the weekend? SATURDAY Still dry with temperatures of 18 now. But the low is still getting stronger, and that cannot be a good thing. It means there is rain around in the overnight of early hours Sunday. It's nothing too heavy hitting the site on this chart but would run through to midday Sunday. SUNDAY No rain around after midday, max temps of 19. The low is now settled over the top of the UK. MONDAY FOR DEPARTURE Worth a mention here for the first time, as there's the thread of a chilly 11 degrees and very wet pack-up on Monday at 9am. SUMMARY So, in this run the low pressure which held off in the 18Z is far more dominant, while we do get some rain this weekend. Where that rain falls this weekend is still uncertain though, and the temperatures after should mean the ground recovers. But it really is all to play for over the next week with the high vs. low. Stay tuned! 1 Quote Link to comment Share on other sites More sharing options...
2019 Posted June 14, 2022 Report Share Posted June 14, 2022 Here's hoping the light north easterly locks in the high. Forecast still looking near perfect, may need a fleece in the evening, as the wind will cool things. 90% sure No Wellies, but still need to keep an eye on this Saturday evening for water.

I don't think you should be festivaling in the summer. I'd swap Wednesdays 23 with Saturdays. Cooler on the way in for set up.

leath02 Posted June 14, 2022 Report Share Posted June 14, 2022 (edited) I'm getting a bit nervous at how good this is looking! Too the point where I dont want to tell my non obsessive friends the current positive outlook Had been dooming them with rain and mud for last couple of weeks, but dont want to jinx it now Edited June 14, 2022 by leath02 Quote Link to comment Share on other sites More sharing options...
