An upper ridge will remain near or over the area through the weekend. A couple of weak fronts will dent the ridge thursday and again saturday night. The ridge will strengthen monday and tuesday for well above normal temperatures.
High and mid level clouds cover western washington this morning ahead of a weak front off the coast. Precipitation echoes are apparent in radar off the coast. So far there is nothing on the coast. Light rain may reach the north coast later this afternoon, but the front will lose strength quickly with little if any precipitation making it into the interior. Today is likely the day that seattle finally reaches a high temperature that is at or a little above normal in 40 days.
The upper ridge will rebuild and gain some amplitude over the area on friday. This combined with a little more in the way of low level offshore flow will further boost temperatures with some spots likely to break 60 degrees. There will still be some high clouds around, but they should be thin enough to call it partly sunny. The upper ridge shifts eastward once again on saturday and weakens somewhat as a front approaches. Weak low level offshore continues as we start the weekend. Despite a little more in the way of cloud cover on saturday, the mild stretch continues with many places getting within a couple degrees either side of 60. Burke/27
Previous discussion... another front attempts to briefly break down the ridge saturday night into sunday. The models have been bouncing around with rain chances. The 00z gfs brings some rain to the olympic peninsula and north interior saturday night into early sunday, but the euro is higher amplitude with the ridge and keeps the area dry. Current forecasts are leaning in the euro direction and will stick with those. From sunday into the middle of next week, its onward and upward as the ridge continues to build before pinching off over british columbia and slowly shifting eastward. Looks like were in line for well deserved stretch of mild spring weather. 27
