Synopsis
Generally dry and mild conditions are expected through the end of the week, with light precipitation possible over the weekend as low pressure moves south from the British Columbia coast. Weak ridging and drier conditions are forecast through the last week of the month, but a return to a more active weather regime is possible as of the first week of November.
Short Term
The dissipating front has left mostly cloudy skies across western Washington this afternoon, with highs in the mid 50s and low 60s. Skies will be clearer on Friday and with slightly cooler temperatures. A low pressure system will be moving into Washington waters Saturday for a chance of showers throughout the day. Morning lows on Saturday will be in the upper 30s to low 40s. Mountain valley locations could be in the low 30s for possible frost and freezes. More of the precipitation will be focused along the Olympic Peninsula with amounts of only a few hundredths of an inch inland through Puget Sound.
Long Term
Some shower activity will linger into Sunday but will remain mostly cloudy. Only a few hundredths of an inch are in the forecast for Sunday but generally conditions look to become drier trending into Sunday afternoon. Some of the ensemble guidance takes the aforementioned low pressure system inland into Oregon early in the week, which would keep conditions on the cooler and cloudier side, other solutions bring in weak high pressure. The majority of the week will be dry. However, there are extended range solutions indicating that the end of the month and into the first week of November may signal a switch to a more active pattern. The probabilistic week two hazards have portions of the CWA highlighted for slight risks of heavy rain, possible mountain snow and some breezier conditions for the immediate coast. Stay tuned to the forecast as details evolve.

Surface winds ease this evening and shift southeasterly early Friday morning, switching back to northerly Friday afternoon.
KSEA...VFR with occasionally breezy NW winds 10-15 kt with gusts to 20 kt. Winds will ease later this evening and become light overnight, but return to northerly Friday morning.

VFR conditions expected to return by the afternoon.
