How does the climate change affect on local weather (micro climates) in cities

Is there a scientific predicted scenarios available for 50 years from now about how the climate change will change the local climate of Helsinki, or some other coastal cities in Finland? In general I am interested to know how the overall yearly humidity levels would act? rains, temperatures & winds being the observation values.

In cityplanning and my field as a landscape architecture these things matter and this changing climate will bring difficult problems to solve. In cities we have even more unnatural climate systems than in natural ”not built” environments, and they vary in each city, so every cities have their own special tasks in cityplanning field.
