Depending on how thick the cloud is it may be but that would effect the whole area or, if it's the uplink that is being blocked, everyone using the system.
Other common causes.
Dish out of alignment. Usually a knock by the window cleaner or poor installation. You are aiming at something the size of a bus about 7,000 miles away. The slightest touch can be a problem.
LNB starting to die.
Water ingress in coaxial cable - usually caused by either poor installation or stress on the cable.
It can also be the receiver on the blink but that is less likely.
