The Pacific Northwest low moves on shore typically in or around the Portland and Seattle area. At location A the type of weather that can be seen is usually thunderstorms and higher elevation rain showers form during the summer. This same area will see coastal rains and heavy mountain snows in the winter. When the system arrives at location B, the Rockies, due to topographic enhancement it can produce heavy rain/t-storms in the summer time, while during the winter this same area can see...
The Great lakes have a huge impact in the weather for the cities that are near the lakes. In the fall and early winter months the lakes can create intense snowfall events known as “Lake Effect Snow”. The reason that this occurs has to do with the water temps of the lakes and also the temps of the air that is moving across them. When an Alberta Clipper system forms in Canada and moves Southeastward towards the US, it brings that cold air and strong Northwest winds over the warmer waters....
The snowbelt is a North American region that lies downwind of the Great lakes, where heavy snowfall is common on mostly the eastern and southern shores of the Great Lakes. Lake-effect snow is caused by cold air picking up moisture while crossing the lake and then releasing it as snow when the air cools over land. Throughout much of the winter, lakes produce lake-effect snow and continuously cloudy skies. This phenomenon continues as long as the air temperature is colder than the water...
