Another atmospheric river is moving across the area with mild and wet conditions. The heaviest rain is at the coast and to the north, especially north of Everett. Rain is much lighter around Seattle, thanks to the rain shadow from the Olympics.
There are Flood Watches in effect at the north coast and from Snohomish County north, where we could see another 1-2″ of rain in Whatcom and Skagit counties. Around 2-4″ of rain is possible in the mountains, especially the Olympics and north Cascades. The exact location of the stalled front will make a lot of difference on how much rain we see, so that is something we’ll keep an eye on.
Tomorrow most of the heavy rain will stay north of the area with just scattered showers for most of western Washington. The front will drag through the area early on Thursday, but will be very light. The afternoon looks mainly dry but cooler in the mid-40s!
Friday looks mainly dry and cool, especially in the morning. There may be a little rain over the southern part of the area on Saturday, with increasing clouds and dry weather on Sunday. Another round of rain will move through on Monday, but snow levels will be much lower which is great news for the mountains!
