there are several different ways, they all have to do with the 3 types of winds: trade winds, polar easterlies, and prevailing westerlies, in the u.s they all colide some where in the middle of our country, but that's why we have such weird weather!
Global winds in the US generally blow from west to east due to the typical westerly flow of the jet stream across the continent. These winds are influenced by the Earth's rotation and the distribution of land and water masses.
Winds in Pennsylvania typically blow from the west and northwest, due to the prevailing westerly winds that dominate the region. These winds are influenced by weather patterns moving across the United States.
I would say it's the westerly winds, seeing as how they are usually going east.
Unequal heating of the Earth creates global wind cells. From latitudes of 30-60 degrees in the northern hemisphere the surface winds travel from south to north. However, because the Earth is spinning the wind gets deflected to the right (left in the southern hemisphere) or to the east.
The Northeast monsoon brings cold air from the continent towards the region, resulting in lower temperatures. During this monsoon season, the winds blow from the northeast direction, carrying cooler air that can make temperatures drop, particularly in coastal areas.
east to west
At the latitude of most of the US, the prevailing winds blow from the southwest to the northeast. This obviously varies depending on the weather systems and geography of any site at any given moment, and Alaska, parts of Texas and Florida, and Hawaii are at different enough latitudes that the winds there may be predominantly in the opposite direction.

Prevailing winds in the US are from the west. Of course, atmospheric pressure can push winds in many different directions.
prevailing winds
east to west
In the United States, the prevailing winds generally blow from west to east due to the Coriolis effect and the rotation of the Earth. This pattern is most pronounced in the mid-latitudes, where the westerlies dominate. However, local conditions and geographical features can influence wind patterns, leading to variations in specific regions. Additionally, trade winds in the tropics blow from east to west.
Being from St. Louis myself and studyin the weather the past 10 years or so I can tell you that there isn't really a predominent wind direction for us. We get mostly south winds during the summer we get north winds during the winter and it blows from the west and sometimes from the east so there is no really predominent wind direction for us.

prevailing westerlies
The Westerlies are winds that blow from West to East across the United States.
The winds can blow from all round the compass. In Britain, an easterly wind comes to us from the continent and. in winter, is often very cold.
