(I only like to watch the trees because I don't have any within falling distance of my home! :) ) Any idea if we will possibly have a good "Mountain Wave" East wind event when this high pressure moves east? I live in Eatonville....we don't get the gap winds but we do get the wave winds! Also usually get hit hard with southeast and south winds.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-56185739615496385062009-01-13T12:57:00.000-08:002009-01-13T12:57:00.000-08:00The NWS threw out the "r" word this morning....LON...The NWS threw out the "r" word this morning...<BR/><BR/>.LONG TERM...PREVIOUS DISC...THE GFS AND ECMWF BOTH SHOW THE BLOCKING RIDGE PERSISTING THRU SUN.

There is a moist mixed layer that extends up to about 1000M, so a few spots of light drizzle, some patchy fog, but mostly a moist air mass in the lower levels but not yet a classic fog pattern. When the inversion sets up and the mixed layer becomes shallow, then dense fog will develop. Whether the fog penetrates up the Cascade valleys will be hard to say, maybe not if the cross Cascade gradient gets up to -5mb (easterly). Right now it is +6mb (westerly) so you are not getting any influence from dry air working westward yet.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-36311023502884688202009-01-13T09:49:00.000-08:002009-01-13T09:49:00.000-08:00For those who think it's better elsewhere, the low...For those who think it's better elsewhere, the lower Methow Valley is socked in with fog, though if you go up to Sun Mountain or even to Mazama you rise out of the fog.

Actually, the shadows are so long this time of year, you're not likely to see snow actually melt. It crisps up at night, loosens up a bit daytime, but the dew points will drop a lot in the mountains and crunchy snow will be the rule. If it was going to be windy it might be slushy, but winds ought to be calm enough for the layer of air against the snow to stay chilled. See if it isn't a lot warmer on the ridges versus in a shady calm spot.<BR/><BR/>These conditions will be just fine for my old K2 KVCs, ha. I actually like the Mission Ridge refrozen icy corduroy. What I don't like is where the snowboards chew it up and it isn't groomed enuf.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-12813639297345211642009-01-13T07:52:00.000-08:002009-01-13T07:52:00.000-08:00It's always interesting reading weather prediction...It's always interesting reading weather predictions from someone in Seattle from my home in the Snoqualmie Valley.
