On his blog, KPLU weather expert Cliff Mass writes:
Sunday should be great....sunny, much warmer air...many will see the mid-50s. A big ridge over us.... Plan to get outdoors!
In general, warmer temperatures are in store, beginning this evening, says Mass in his weekly weather conversation with KPLU. You can expect a little of everything on Saturday, before it clears out on Sunday.
Next week, Mass says it will be cooler and wet again, fitting with the La Nina pattern that's settled in place.
