Today's Forecast

Updated Friday 4:05 p.m.

'Tis the season to be stormy...

-RA -RA -RA -RA -RA, -RA -RA, -RA, -RAAAAA

(Weather observation joke, -RA = light rain)

-RA will be a common note in the Seattle observations, maybe even just a plain old "RA" for moderate rain or "+RA" for heavy rain as potent storms roll through this weekend, bringing a lot of rain to most and gusty winds to some.

Let's begin with the winds, which will be pretty strong for those areas susceptible to southeast winds. A High Wind Warning is in effect for the coast from midnight to 9 a.m. Saturday, and until noon for Whatcom County, the San Juans, Whidbey/Camano Island and the Admiralty Inlet area for southeast gusts as high as 55-60 mph. A lesser Wind Advisory is in effect for gusts to 45 mph in Skagit County.

The greater Puget Sound area is protected from the southeast winds by the Olympic Mountains and no wind advisories are in effect here, just breezy winds to 20-30 mph overnight.

Rain will be increasing overnight as well. What have been a few scattered showers this evening will turn to a widespread steady rain past midnight. Lows will be in the mid 40s.

For both Saturday and Sunday, just count it rain at times -- Saturday will be more of the soaker day while Sunday will be a lighter rain, but dry periods will be fleeting. Highs will be in the low-mid 50s.

The mild temperatures and heavy rains is also bringing flooding concerns, and a Flood Watch is up for all mountain-fed rivers in Western Washington.

Rain will begin to taper off late Sunday and we'll just see a few showers on Monday with highs around 50.

That is probably your best dry day of the next few days as weaker systems will push through on Tuesday through Christmas Day, keeping skies mostly cloudy with scattered showers. Temperatures will gradually cool a bit as the flow turns more northerly, with highs drifting down into the low-mid 40s by Christmas.

Looks dry for Friday as well but relatively chilly with highs in the low 40s and lows in the mid-30s.

Have a great weekend!
