The jet stream shows a large trough of low pressure ( “U” shaped area over us) pumping a lot of moisture our way. A frontal system has pushed through the Pacific Northwest bringing rain, wind, and lowering snow levels with it with more to follow behind it and another one is sliding down the California coast causing some very active weather there. Be prepared for possible slippery roads at least late night and early AM for at least another day.
