This stormy pattern began Wednesday bringing clouds, cooler temperatures and widespread rain to the region. A dip in the Pacific jet stream will start to break the area of high pressure that has baked the Northwest for much of the past month.
HOW HIGH PRESSURE AND LOW PRESSURE DRIVE THE WEATHER
The jet stream acts as an atmospheric conveyor belt for storms and ushered in a stronger storm system Wednesday evening into Thursday morning.
