A thunderstorm had been predicted for the night with a probability of 30% 12 hours before the event, at the go-or-skip point. The government decided to cancel it and postpone to the 27th. The thunderstorm did not happen. The government blamed the meteorologists.

Following weather will take place with a probability of 30%:
The following weather phenomena are expected to arise temporarily:
From 10:00 UTC (Saturday 20 August 2022 12:00 local time) at 21:00 UTC (Saturday 20 August 2022 23:00 local time), Wind: Variable in direction, speed: 18 knots (33 km/h) (9 m/s), with Gusts of maximum speed 36 knots (67 km/h) (19 m/s).
Minimum horizontal visibility: 1400 m.
Weather: Thunderstorms Rain Hail .
Weather: Squall .
In 2006 we had a similar "setup". Then the early reports were ignored, and by the time a report with a higher probability arrived in the afternoon, it was too late. The outcome: http://news.bbc.co.uk/2/hi/europe/5269642.stm
Interesting. If they only predicted 30% probability of a thunderstorm, why did they make this statement?
>The service posted a public apology on their Facebook page on Sunday, explaining that the "least likely" outcome happened, and that uncertainty is part of weather forecasting
If there's a 30% probability of a thunderstorm, no thunderstorm is the most likely outcome, not the least likely.
