The Cascades & Areas West
A frontal system will gradually move across the area today allowing colder air to filter in. A Winter Weather Advisory has been issued for the WA/OR Cascades where 4 to 10 inches of snow will be seen across the Washington Cascades above 3000 feet, and 8 to 10 inches of snow for the Oregon Cascades above 3000 feet up north to 5500 feet for the southern mountains.
Another frontal system will cross the western areas late Saturday for more rain and southerly breezes. This will be followed by yet another weaker front Monday. Tuesday into Thursday will see larger breaks between passing fronts that will be weaker with less precipitation.
Areas east of the Cascades
Precipitation will spill east of the Cascades into central Oregon and Washington today. The precipitation will decrease after midnight tonight through Saturday over the eastern zones. A new weather system will cross the region Saturday night and quickly exit the area on Sunday. This system will bring mainly rain. A ridge of high pressure with drier conditions will move in and prevail on Monday.
