Weather changes too fast!

Please excuse the Google translation:
Yesterday evening I took a flight over Nigeria.
It was late afternoon dense compact thunderstorm cells active, which forced me to a large detour my route.
And now the problem:
Suddenly, the entire storm system within 30 seconds disappeared before my eyes. The clouds broke up, the turbulence at the edge of the storm zone were blown away. This cahanges within 30 to 40 seconds. Thunderstorm of 30,000 feet in height within one minute away. Something must not be present. Since you have to repair, so something does not happen in the next version. Storms come and go, but not within a minute!
Hope this improves HiFi from!
