SPOKANE, Wash. — Another seasonal cold front will pass straight through the Inland Northwest. This time it hits during the middle of the day on Sunday. While we're expecting another round of rain, the wind gusts are forecast to be slightly stronger this time.
The setup is two low-pressure regions over the Pacific Ocean that will assist one another in terms of the weather impact it'll have on the region. The smaller core that originated out of the tropical Pacific waters is what will carry the frontal boundaries responsible for when the rain chances are most likely. Meanwhile, a much larger low pressure over the North Pacific will push the cold air forward into the Northwest, which the first area will use as energy and momentum forward.
