Forecast

The barometric pressure in Metropolis is relatively low due to its location in a valley. It often falls below 30 inches. When a low-pressure system moves into the area, the pressure can drop significantly.

Metropolis is surrounded by hills to the north and east. The Ohio River lies to the south. This unique landscape creates a channeling effect on winds. As winds blow from the north, they are forced to rise. This leads to cooling and condensation, resulting in increased cloudiness.

The city's proximity to the river also contributes to its weather patterns. Moist air from the Ohio River moves into the city, adding to the humidity. During the summer, this can lead to high humidity levels. In the winter, the river's warmth helps moderate temperatures.
