sunburn, measles and the clap - it’s amazing it sells out so quickly!

Honestly that article is a wild ride. Wasn't expecting the sudden mention of measles at all. All the talk of water bottles then BAM measles in the next paragraph left me feeling bewildered.

Much improved gfs so far into the festival itself!

and above 21c so if it does rain, the ground will dry in no time

[The Red Telephone]

Want: Perfectly dry, warm festival

Would accept: Measles, STD

Avoid: Pissing it down for 5 days

This is looking better.

The 12z is rolling out.   It’s a pre-festival shocker…..hours and hours of heavy rain…  let’s hope the festival days themselves are a bit better…

Sunday:

 

Tuesday:

Rain at any point over the weekend, even heavy, is welcome. Tuesday less so, but if it can clear up by mid afternoon that’s not a huge problem for your typical festival goer. 

Edit: this weekend I mean, not during the festival.

Could do without it TBH

We'll be trying to site heavy vehicles

[4AssedMonkey]

I for one am willing to contract measles if it stays dry for all 5 days. My immune system’s nails. Will see that off in no time. 😜

For sure. I meant for your average festival goer (i.e. arrives Wednesday). Still think enough to dampen the ground over the next few days would be beneficial all round.

I'd like it to be dry on Tuesday please!! Just let me set up in the dry 🙌🏼🙌🏼

Add Sunday to the pot. This run has about 1mm of drizzle the whole weekend.

[Euphoricape]

It's back on!

🤣🤣 I'll be doing one big breakfast on the Wednesday morning while we're waiting for the queues to go down. Be there or be square (After that, it's pancakes or nothing!)

[Suprefan]

Only 27? : laughs in desert :

[briddj]

We move on to the 12Z. Can we recover from the shock of the last run?

GATES OPENING

Still quite a lot of rain on Sunday, which is definitely becoming a theme as the timeframe gets more reliable.

On this run there is more rain in the early hours of Tuesday, and some very light stuff during the day. Again, a consistent theme.

But Monday temps of 22 will clear up the Sunday rain, with decent temps of 19 on Tuesday.

For Wednesday at 9am, it's dry (having been since early evening the night before) and really quite warm at 18.

We had a troublesome green pocked of low pressure in the last run (left) and while it is present on this run (right) it's much further north before it's pushed away.

It means Wednesday is essentially dry - the rain showing on this chart is nothing. Highs of 20.

THURSDAY

Completely dry with highs of 22.

FRIDAY

There's a very small amount of rain around in the early hours of Friday, with the day itself completely dry with highs of 24.

SATURDAY

Another completely dry day, with highs of 21.

 

SUNDAY

Another completely dry day, with highs of 21.

SUMMARY

We are back to an exceptional run to recover from the last horror.

Any rain in this run for the festival days would be completely insignificant, with warm temperatures throughout.

COME ON!

But there remains uncertainty about what exactly will happen from Thursday onwards. We don't have it in the can yet.....

[Sheffield Steve]

Let’s take a Europe-wide look this time.  It’s all change with the 12z GFS. Plenty of rain over England in the days running up to the festival, but the other models are yet to agree on this so definitely can’t be relied upon.

After that things aren’t too bad at all.  Pressure builds from the east to dampen down any showers on Wednesday and Thursday.  This high is shoved out of the way by an area of low pressure coming across Ireland and into Scotland, which might produce a few showers for the south of England on Friday. 

After that, pressure builds over the country from the north and gives us a dry Saturday and Sunday with temperatures around 21c.
Big improvement, but there is still far too much low pressure all around us.  It will be all change in the next run…. MORE RUNS NEEDED
