I`ve been seeing this possibility for last few days now, and looks like Seattle NWS is catching on to what I`m seeing/thinking.andycottlehttps://www.blogger.com/profile/12696751462397354299noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-5508945028856675552009-01-29T16:16:00.000-08:002009-01-29T16:16:00.000-08:00This comment has been removed by the author.andycottlehttps://www.blogger.com/profile/12696751462397354299noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-30786234367123387252009-01-29T12:19:00.000-08:002009-01-29T12:19:00.000-08:00Cliff, you know that you jinxed yourself by asking...Cliff, you know that you jinxed yourself by asking that question.

Eventually, of course, the sun becomes high enough -- and thus intense enough -- to reverse the net loss and start warming the atmosphere, but not until some AFTER sunrise. I like that Mr. Moore considers factors such as upper-atmosphere dynamics and early-morning human activity, but I suspect the impact of those factors is insignifcant. Just as the coldest day of the year is not the winter solstice, the coldest time of day is not the moment of sunrise.Brendan Patrickhttps://www.blogger.com/profile/01675389836643728841noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-57317305929201097002009-01-29T10:47:00.000-08:002009-01-29T10:47:00.000-08:00Oh wait - I just realized where I had that impress...Oh wait - I just realized where I had that impression from.

Similarly, our car is parked outside next to the intersection of 39th Ave NE and NE 148th where there is some (noisy!) pre-dawn [commute?] traffic up a steep switchback on a 100'(?) hill from Beach Dr. NE below the Burke Gilman Trail, so I would expect hot exhaust to raise its thermometer temp by several degrees some time before sunrise. <BR/><BR/>So, I'm fairly confident that the "before dawn" forecast is correct, but quite unsure of the timing and temp-rise effects from these models, and I'm betting that Cliff will point out other models and mechanisms, some of which might even have the effect of delaying min temp until after "sunrise" on cloudy days. (Certainly,new wind from colder regions can cause major temp drops, even at mid-day, and I suspect that there are near-dawn air circulation patterns that we non-meteorologists are unaware of, that could have major effects on the min-temp timing.) That's why Cliff's blog is such a major local asset: we don't have to pay tuition to learn from him!<BR/><BR/>BUT (or THEREFORE, as we Math types have to deduce...): We all SHOULD<BR/>(a) join the KUOW 94.9FM club and donate to KUOW and NPR to support Cliff's Friday Weekday forecasts;<BR/>(b) join Cliff at REI, Town Hall or NOAA, buy his book and get his autograph, and cheer him on...,<BR/>(c) lobby state govt to support UW and Cliff's dept; and<BR/>(d) lobby all govts to get the Doppler radar installed that we so desperately need for reliable forecasts. As the "Mayor Salt Nick" poem suggests, if we can afford solar panels for our stadia (a very good "green" idea!), why not good radar too?<BR/><BR/>Cliff fan and autographed-book owner/reader/promoter Bob MooreAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-39435211336185585862009-01-28T23:49:00.000-08:002009-01-28T23:49:00.000-08:00Just after sunrise.Just after sunrise.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-76351767295657814722009-01-28T23:21:00.000-08:002009-01-28T23:21:00.000-08:00I'm going to say just after sunrise, which would b...I'm going to say just after sunrise, which would be about 8 am at this time of the year.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-31613586865116350232009-01-28T22:49:00.000-08:002009-01-28T22:49:00.000-08:00My answer is just before sunrise when you are not ...My answer is just before sunrise when you are not taking into account any storms or winds which can change temps drastically throughout the day.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-36313026564631686822009-01-28T22:21:00.000-08:002009-01-28T22:21:00.000-08:00between 4am and 6am typically (I am guessing).between 4am and 6am typically (I am guessing).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-77595785230610185192009-01-28T22:08:00.000-08:002009-01-28T22:08:00.000-08:00Olalla: Sunny afternoon, good day for a walk.
