Oregon's weather varies widely from east to west. Eastern Oregon is much drier than the western part of the state, and the Cascade Range acts as a barrier, preventing moisture from the Pacific Ocean from reaching the east. As a result, summers in eastern Oregon are long, warm, and dry, while winters are cold and snowy.  While in the western part of the state, you can expect wetter winters with beautiful dry summers.  Living in Oregon you'll find temperatures are pretty mild year-round.
