There'd still be dangerous windstorms and potential tornadoes, and thunderstorms would be guaranteed due to the moisture in the Tundratown air (it snows there).
I thought of a second idea for a barrier, in the form of blowing an incredibly strong wall of air upwards to keep them separate, but the air would have to me moving so fast that the air friction would cause lightning constantly, and the fact we haven't heard any thunder in the movie disproves this idea. The only things going for it are the relatively low-tech needed, and the fact there seem to be no airports
A third idea would be to just wave a wand and say "I CAST WALL" and just have magic kept extremely regulated in the world. Magic is a weakass fucking explaination, though, but you could still play with the idea and explain away so many problems like weather, mass transportation (an entire coastal city with no major shipyard or docks and limited land travel), the conversion of the city from its likely older forms to its modern high-tech form (the city is at least 100 years old based on the newspapers, and the alternative to that is to assume the place has a bleak future with 100 years of little scientific advancement, which can't be possible due to Bunnyburrow not catching up technology-wise in those 100 years unless the world is a dystopia where Big Brother dictates everything about anything.)
tl;dr- fuck it, I cast magic and Byron/Moore would likely never even acknowledge the question, and if they did we'd get another Z$ shenanigans
