KING5 Meteorologist Jeff Renner said another weather system is expected to move in Tuesday, bringing another round of rain and wind to the lowlands and heavy snow to the mountains.
The heaviest rain will likely be between 10 am and 3 pm. Up to an inch will be likely in places. Check the forecast
Once the cold front moves through, snow levels will begin to drop, and may bottom out around 1,000 to 1,500' on Wednesday. That could bring mixed snow/rain or wet snow on some of the higher inland hills-such as Tiger, Cougar, Squak and the Somerset area, Renner said.
In the mountain passes, heavy snow will be likely with up to a foot of snow Tuesday and again Wednesday, and possibly more than a foot Thursday.
Closer to sea level, the onshore flow of cool, moist and unstable air Wednesday could set off not only rain showers, but also isolated ice pellet or thundershowers.
Flood warnings are in effect for the Chehalis, Skookumchuck, Newaukum, Deschutes and Skokomish rivers.
