Make sure that you don’t zip up both entrances, or you will get Schrodinger’s Cat.
Don’t zip up both ends with him in it otherwise you will need a new tent!

There's a long term weather forecast tool here. It takes information from about 30 forecasts and produces an average.

I've put in the coordinates for the Le Mans circuit (I think). The bottom line shows the forecast of rain and the top two show temperature at two different altitudes, which give an idea of how the temperature will change at ground level. I'm not an expert myself and only use this as a guide, so if you have any questions please ask the cat.

Well that's confusing. so it's going to be between -20 and 15 degrees? I might need to bring a jumper.

Add 10 to 15 degrees to the 850hPa figure for a rough guess at the temperature at ground level. 850hPa is about 1.5 km up, but is used as it's much more stable than measurements at ground level.

Any updates to be expected from https://www.gavsweathervids.com/ ?

Not that I need his fictional forecasting as obviously the cat has spoken.

I always enjoy Gav's vids. Sooo much detail. Sooo little accuracy =) Didn't he predict rain last year at one point?

Le Mans is not complete without Gav talking about the Azores High.

I see Accuweather is forecasting some periods of rain currently for the Saturday afternoon and a shower for the Sunday....the weather could add its own Balance of Performance filter (& Toyota therefore might not have it all their own way!)

As I open the thread I hear thunder rumbling outside. The cat has spoken, but if you are seeking a second opinion you might like to consider here:-

The weather station is on the ring road next to the Total petrol station less than a mile from the circuit.

Given the Toyota/Rebellion/Toyota/Rebellion positions at the end of the test weekend I'm not sure we will need the weather, or any other major BoP changes.

Accuweather saying low-mid 20s with the odd shower. That would make an entertaining race.
