The Red Bull Ring in the Styrian mountains holds the eighth round of the 2021 Formula 1 World Championship, with the whole weekend taking place with threats of rain looming.
Teams made a point of getting as much track time as possible on Friday due to the looming clouds, but rain never properly hit the circuit. Saturday was much warmer and clearer, but the same changeable conditions that threatened on Friday are set to return for Sunday's race.
According to our friends at WeerOnline, the air in Austria will gradually become more unstable.
During the race, the chance of showers will be much bigger. The temperature will rise quickly on Sunday, eventually reaching around 27 degrees. At first there will be a lot of sunshine, so the track temperature rises quickly.
But, in the afternoon, stacked clouds will form, which may develop into a heavy thunderstorm in the region. The maximum temperature will be 27 degrees. The easterly wind is weak, but showers can cause strong wind gusts.
If a thunderstorm develops, it will move slowly. A thunderstorm that will make the track wet has to occur close to or even right above it. The chance of this happening between 14:00 and 17:00 is about 30%. The chance that it will stay dry is, therefore, higher.
The eventual shower can be very intense with thunderstorms and a lot of rain in a short time. It is, however, very localised. It is even possible that a part of the circuit will be soaking wet, while another part will remain almost dry. A heavy thunderstorm can also cause wind gusts, even if the rain falls a few kilometres off the track.
