Areas that are likely to see an inch or more of snow will be Hood Canal (especially along the west of 101 near the Olympics) and the East Puget Sound Lowlands for areas like North Bend (where temps will be around 30). Therefore, will issue a Winter Weather Advisory for these two lowland zones.Will there be thunderstorms on Sunday in the Pacific Northwest?
A trough over the PacNW will maintain showers as we move into Sunday with the threat of more thunderstorms possible. The highest confidence for t-storm development on Sunday will be during the afternoon/evening with a convergence zone (near the Snohomish/King line).Where are the thunderstorms in Washington State?
NOAA satellite imagery showing plenty of cold-topped cumulus clouds offshore, mainly off the Washington coast. That will be most probable area for any evening thunderstorms, but will keep some mention of such for rest of the south Washington and north Oregon as well.Will a shortwave impact the pacnw on Friday?
Guidance is in good agreement that a shortwave will impact the PacNW on Friday with widespread precipitation for our forecast area as an atmospheric river is directed into Oregon and Washington.
