They've been pretty reliable.<br /><br />Today (Wednesday, July 22nd) I noticed that the wind is coming out of the south here in Seattle and that it began early, like 8 or 9am. The marine synopsis says there is still the typical high surface pressure offshore with low pressure east of the Cascades creating onshore flow pattern. I'm trying to square that synopsis with the early/southerly wind patterns today.<br /><br />Did the center of the NPH shift south and the onshore flow is finding its way through a gap south of the Olympics?<br /><br />Any insight would immensely help this sailor!Bob Hallhttps://www.blogger.com/profile/15598368072366661638noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-32672933962380028162009-07-20T08:15:35.810-07:002009-07-20T08:15:35.810-07:00Joseph, actually, yes Saturday could be quite hot ...Joseph, actually, yes Saturday could be quite hot too - it's looking again like that ridge is going to build by late Friday/Saturday morning. From what I'm looking at, I wouldn't be surprised to see temperatures in the upper 90s to near 100 in some spots, particularly away from the Sound and Lake Washington, south of Bellevue, near the foothills, on Sunday.<br /><br />Here are images from yesterday's 00z GFS-WRF run of temperatures at 5pm Saturday and 5pm Sunday:<br /><br />http://www.atmos.washington.edu/mm5rt/data/200907<br />2000/load.cgi?images_d2/wa_tsfc.144.0000.gif<br /><br />http://www.atmos.washington.edu/mm5rt/data/200907<br />2000/load.cgi?images_d2/wa_tsfc.168.0000.gifWeather Is My Lifehttps://www.blogger.com/profile/11959087601911808613noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-9369421951117086652009-07-20T08:14:49.665-07:002009-07-20T08:14:49.665-07:00This comment has been removed by the author.Weather Is My Lifehttps://www.blogger.com/profile/11959087601911808613noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-65150365246563879582009-07-19T21:25:08.665-07:002009-07-19T21:25:08.665-07:00Joseph, as suspected, the odd-looking cutoff low (...Joseph, as suspected, the odd-looking cutoff low (particularly for late July) the GFS was hanging around our region for the weekend is now absent from the GFS again, which makes a lot more sense. The models are usually quite a bit better a week or so in advance in the summer than they are in the winter, at least across this region where rainfall is very sparse in July. Between the ECMWF, GFS, Canadian, and even the NOGAPS of all models, all showing the 500 hPa high building right over the Northwest by the second part of the weekend, there is increasingly significant evidence of intense heat (for the Northwest, that is) headed here for Sunday into next week.<br /><br />I'd say probably upper 80s Saturday, and mid to upper 90s could be possible next Sunday and Monday, hotter in the eastern highlands and closer to the foothills.Weather Is My Lifehttps://www.blogger.com/profile/11959087601911808613noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-4509374376450519042009-07-19T19:20:38.666-07:002009-07-19T19:20:38.666-07:00If we have a drier fall...and it sounds like it wi...If we have a drier fall...and it sounds like it will be, almost like an eastern fall, it could make for nice sky-watching, leaf-kicking etc. But for snow pack...hmm.

This of course translates to a little more in the way of cloud cover and temperatures about 20 degrees cooler than it had previously appeared for next weekend. At the same time, a cutoff high develops to the west over the Pacific before the low retrogrades back west and the high merges back into the high over the western US the week after for hotter conditions in the NW then.<br /><br />All this looks rather strange.
