While not quite as crazy as your situation, I too have been seeing some particularly crazy weather fluctuations down south in the Midwest of the US. It's crazy trying to get blankets on them when it is 1 Celsius and before it rains in the coming hour... and this next night it will drop to -13 Celsius... AND then the next day is up to 7 Celsius and it is too warm for blankets. Drives ME crazy sometimes, I can only begin to imagine what level of madness your currently on.
I sadly think this is going to be our new "normal". We're planning some major renos this summer to improve drainage when the ground is frozen as the original bank barn was not built with flash flooding in mind 😑
