Missouri experiences a humid continental climate with hot, humid summers and cold winters, plus some of the most severe thunderstorm and tornado activity in the country. Ice storms every few winters can suspend work for a week or more, and the Kansas City and St. Louis metros sit directly on the main severe-weather corridor that shapes wind and impact specifications. For electrical panel upgrade projects specifically, this means timing and material selection are key factors in both cost and quality.
Less regulatory burden and simpler permitting processes help keep overall project costs down.
