The weather pattern over the United States is undergoing a big change today. While the eastern two-thirds of the nation has enjoyed mild temperatures the last several days, an Arctic front is about to bring much colder conditions to areas east of the Rockies this week.
For the Pacific Northwest, a large high-pressure ridge will set up over the region bringing a prolonged period of dry and stable weather. For Northcentral Washington today, bands of mid and high level clouds will spill over the top of our high pressure ridge but it will be a nice day with light winds and high temperatures around 40 degrees.
Late Tuesday through Sunday, we will see a fairly stagnant weather pattern with areas of fog in valleys and lowlands. With those foggy conditions expected this week, travel could be difficult with slick roadways and poor visibility. Along with light winds, we will see high temperatures in the mid 30’s with lows in the mid 20’s.
