A spooky Vincent Price movie may not be necessary for Halloween night after all. The forecast alone should be frightening enough for most folks. Active weather is likely this weekend, as a strong jet stream and potent storm system impact Washington. Right now, Halloween (Saturday) night is expected to be very rainy for western Washington, and potentially wet for eastern and even central Washington. More likely, strong wind will be an issue for much of the state, although air temperatures should be quite mild for this time of the year.

Sunday will be a day of many changes for Washington, and not only in terms of the month and the time. November should quickly transition to a cooler regime following a cold frontal passage later this weekend. The showers and wind are likely to taper by early next week, as the coolest air mass of the season assumes residence over the state. Although most of the precipitation is anticipated to fall before the cool air arrives, the mountains could see some much needed snow showers for later Sunday into early next week. Despite the apparent chill next week, conditions will hardly be unprecedented for this time of the year. Given the changeable season and recent warmth, even a decrease to just normal early November temperatures would seem stark in that context. Winter is certainly not beginning in the lowlands, but the upcoming weather should be a strong contrast to the recent conditions. The middle of next week looks to be drier and calmer but quite cool. Overall, an interesting and significant weather period is likely in the coming days.
