Clearing skies letting the heat out overnight will make for a pretty fall day on Sunday.   With partly to mostly sunny conditions, highs will warm into the low 40s for most of the region.   You should definitely take advantage of the nice day while it's in place - certainly enjoy it and get in an autumn walk or toss the football around a bit.   But if you have a yard full of big trees that have been dutifully shedding this month, you should also think about getting in a good round of aggressive raking.   It may be the last chance you have to do so for awhile, and if you can un-clog the storm drains around your house, you won't be sorry, it may prevent urban flooding in your neighborhood during the week to come. That's because the weather script here is going to take a 180-degree turn as we slide into Monday.   A gusty, moisture-laden storm is going to plow into the Northwest by Monday morning, and it will be a soggy and blustery start to the work week.   As the rain returns, highs will climb back into the upper 40s around the Sound. 

We are starting out soggy this morning thanks to a weak front passing through as we speak.  The light rain could make for some slick roads so lets be a careful out there. 

The front bringing us the rain will pass through by this afternoon.  Plan on wrapping up the day with a few sunbreaks and highs in the mid 50s.

Monday is a critical forecast for kids.  We want to make sure all that work they put into those costumes doesn't get washed away.  Right now it looks like the prime 'trick or treat' hours will be mainly dry.  Monday will start out with a few lingering showers, but they won't stick around too long.  Highs will only make it to the low 50s.

Cool and dry weather for Tuesday with partly sunny skies for most of western Washington. 

Another gray start to your day across Western Washington.  Some spots are starting out in the low 30s!

We will get some sunshine by the end of the day, but it could take a while to burn through the marine layer that moved in overnight.  Highs today will hit the mid to upper 50s.

You can just make a photocopy of today's forecast for Monday.  We might be a few degrees warmer, but that's about it. 

High pressure will build in to our east on Tuesday giving us an off shore flow.  With no active weather headed our way, we should get more sunshine and warmer temps.  Highs on Tuesday will hit the mid to upper 60s.

Clouds will move back in on Wednesday with a few showers creeping in Thursday.
