After a wonderful, quiet weather day we can expect a return to cloudy and rainy weather to make a comeback.
Tonight will be overcast and some rain showers will move in from the Pacific after midnight. Rain will be observed on Sunday - mainly in the morning hours - with a break in the action after noon. Late in the day tomorrow we will be waiting for more rain as another atmospheric river moves toward Washington.
You can expect a wet and windy day on Monday. Computer forecast models predict over an inch of rain in the lowlands and upwards of 3 inches in the mountains. More rain for the mountains means more run-off and rising rivers by Tuesday and Wednesday. The Skagit, Snoqualmie, Snohomish, White River, Cowlitz and Skokomish could all rise again by mid-week. It does not appear that major flooding is in the outlook but this could quickly change if we get more rain than expected next week. Stay up to date with every forecast that comes out next week.
There are some other weather threats that will increase on Monday as the heavy rain moves back into the area. Winds will increase to over 40 mph on the coast and gusts over 30 are possible around Puget Sounds. Saturated soil from the atmospheric river event last week means that landslides in the mountains and falling trees could become very disruptive on Monday. Snow level remains high for the first part of the week so the passes will not be affected with snow; however, the threat for road closures because of possible landslides and down trees will be high on Monday.
Another wet weather system will move through on Tuesday and Wednesday. This system is forecast to bring colder weather to the mountains and drop the snow level by Wednesday. As more wet weather moves in this week, our ski areas should start to see accumulating snow down to 2,000′ by the middle of the week. Higher elevations in the Olympics and Cascades will notice plenty of accumulating snow by Friday.
Temperatures will be in the 50’s in the lowlands through Tuesday and drop back to the 40’s by the end of the week.
Weather details to remember:
* Rain showers tomorrow
* Heavy rain and windy weather Monday
* Some rivers rise again on Tuesday and Wednesday
* Colder weather with mountain snow by mid week
