Happy Friday! We’re mainly dry to start the day, but a few showers or sprinkles will be around. We’ve had a little moisture on the radar around the Skagit and Snohomish County line. There could also be some mist in the fog around the Olympia area. We will dry out and stay cloudy for the first half of the day, then partly cloudy conditions this afternoon.
After a mainly dry day, some showers will likely develop late in the evening hours, particularly in the central and north Sound northward to the Canadian border. Also, a Puget Sound Convergence Zone from Seattle to Everett could enhance rainfall into Friday night and Saturday morning.
Through the start of Saturday, some rain showers will continue to move through the area as the trough of low pressure responsible for the rain showers pinwheels across the Northwest U.S. and southern British Columbia. By late Saturday, rain showers will taper west of the Cascades, though there could be a few showers in north-central Washington into Saturday evening. There could be an isolated thunderstorm in some of the heavier showers.
Rain totals for Friday evening through Saturday will be highly variable with most areas getting less than a tenth of an inch (some none at all) and spots under the convergence zone possibly picking up more than a half-inch of rain, though totals like that will definitely be isolated.
Highs on Saturday will only be around the upper-60° in Seattle whereas the normal high for Saturday is 76°.
Expect a bit more sun on Sunday after morning clouds.
Next week looks to start mild and rain-free but another weather system could arrive with rain around next Wednesday and Thursday, containing some residual moisture from the remnants of once-Hurricane Lala, which cause flooding on Hawaii nearly two weeks ago. It’s not unusual for tropical systems to traverse the Pacific, only to have their remnants absorbed into the eastward-moving Pacific jet stream.
The rain chances we see next week will start the month of September on a potentially soggy note, and the long-range outlook continues to point toward a better chance of above-average rainfall through early to mid September.
