On Friday I tried to get some friends of mine to go but they all backed off based on the weather in Seattle saying it would be worse in the mountains. This is true in the winter but not this time of year. I went up Defiance Mountain off I-90 just west of Snoqualmie Pass. Once you get above 4000' feet it's beautiful sunshine and you can see clouds rolling through the valleys below you. I was able to see Rainier and Adams quite well. Bonus only one other car in the otherwise overcrowded parking lot!Unknownhttps://www.blogger.com/profile/13997650490658794149noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-54776198195866074032010-06-26T13:05:15.436-07:002010-06-26T13:05:15.436-07:00@Dan:

And the rain gauge at Volunteer park showed a measurable rain rate of a tenth per hour (10 times more than a trace -- enough to get wet).<br /><br />http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=KWASEATT110&day=25&year=2010&month=6<br /><br />He said he wasn't seeing rain gauge tips at that time (9am) in his network but did see them in the following hour (as the drizzle moved?). <br /><br />He also pointed out (because I hadn't noticed) that KATX was in clear air mode. So with higher sensitivity you could see a large patch of drizzle (but below 30dBz but orange in clear air mode) on the wxdisc radar plots at the UW.<br /><br />I suspect there was a fair amount of perhaps local drizzle between 9am and 10am around the city but it was so diffuse and relatively low rate it got decluttered out of the radar. For the Rainwatch site it wasn't a significant amount for them so it's not a problem for them.<br /><br />One comment I had to Phil was it's interesting how the low apparently objective measurements deviated from the perception at ground level. If you stayed outside on CapHill for the half hour around 9am Friday you were going to get wet but the radar said it was fine and the rain gauges weren't tipping. So that method isn't perfect!<br /><br />Oh, and to use the comment my Irish Mom used to use in England about fine rain making you wetter. I used to laugh but now I think perhaps the Mythbusters need to take a look :-)Kevin Purcellhttps://www.blogger.com/profile/18157202870194603923noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-28752971297595698342010-06-25T20:52:52.840-07:002010-06-25T20:52:52.840-07:00Hey Cliff-
Can you explain why I couldn't fin...Hey Cliff-<br /><br />Can you explain why I couldn't find any trace of this morning's rain on the radar (I use National Weather Service and KIRO). I live over in Sandpoint and try to use your trick to time my bike commute with the radar, but I couldn't do it this morning (I got soaked!).<br /><br />One of my colleagues at the University said he had the same problem this morning when trying to time his walk to the bus stop. What gives with the lousy radar signature of this morning's showers?!<br /><br />Thanks.Danhttps://www.blogger.com/profile/02202692259718746720noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-62911129204904851872010-06-25T17:25:09.888-07:002010-06-25T17:25:09.888-07:00I can for the right price...I can for the right price...Cliff Mass Weather Bloghttps://www.blogger.com/profile/13948649423540350788noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-87003790577941065422010-06-25T14:25:02.670-07:002010-06-25T14:25:02.670-07:00I love how you explain the weather.

As a sailor becoming more knowledge about the weather and forecasting is important to my safety and my enjoyment of the boat.<br /><br />Still, can't you make it sunny with 15 knot winds alternating directions on Saturday and Sunday and then rotating each weekend so we can sail downwind to and from our destinations but still get to N one weekend and S the next. ;-)Anonymousnoreply@blogger.com
