Which wind direction is often associated with declining weather in Maine?

The east wind direction is often associated with declining weather in Maine due to the prevailing atmospheric patterns and geographical influences unique to the region. When the wind blows from the east, it typically brings in moist air from the Atlantic Ocean. This maritime influence can lead to the development of clouds and precipitation, particularly as the moist air rises over the land, cooling and condensing into rain or snow.

In contrast, winds from the north and west are more likely to bring drier, cooler air, which is generally associated with clearer and more stable weather conditions. Winds from the south can also introduce warm, moist air, but they tend to be less prevalent in causing immediate declines in weather compared to easterly winds. Therefore, the eastern winds are particularly noteworthy for their connection to deteriorating weather, making this answer the most appropriate choice.
