Now the extremists are labeling everyone a "denier" if they don't see the sky falling on their heads, right now.<br /><br />I've followed the science on AGW since the issue first arose (long time ago), and see it as a huge global threat to world population and political stability, but by the definition of some of these posters, I suppose I'm a "denier" too. <br /><br />Some of these discussions are the reciprocal of the true deniers, who will (falsely) interpret a cold winter as evidence that AGW is bogus. These posters are taking a couple of years of weather and using it to fan the flames, if you forgive the pun. <br /><br />The backlash from over-hyping weather as evidence of near term disaster will likely drive more and more people like me into a "moderate" camp that refuses to acknowledge the extremes from both sides, and instead follows the sober science. If that makes me a "denier", then so be it. <br /><br />John Marshallhttps://www.blogger.com/profile/08271037292493818827noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-12125608708308286412015-08-19T14:47:40.824-07:002015-08-19T14:47:40.824-07:00My guess would be average precip as blob and el ni...My guess would be average precip as blob and el nino battle it out this winter, but warmer than normal again seems to be a lock. As Cliff pointed out though, our winter was so far below average for the passes last winter it would be hard to be on par with that anomoly again.

Or is the "warmer' water going from the average 55 degrees to 59 degrees and so not enough to provide much additional energy.

Congress didn't accept this and under the threat of being terminated our very first group of silva culturist found they were to redo the study to include all of the west for cutting. Many of these newly minted silva culturist, to there credit resigned instead of lying for the cut.<br /> As long as we cut strictly to supply the timber lobby instead of following the forest services first and founding principle of watershed protection ,we will have lots of big fires.Anonymoushttps://www.blogger.com/profile/05492447368865204342noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-81720707193999175262015-08-16T15:48:07.489-07:002015-08-16T15:48:07.489-07:00

We got drenched on the same weekend last year so even with the hot summer we were keeping an eye on the forecast. The weekend before we had a moment of panic at the prediction of thunderstorms on the day of our event. And then as the week progressed the thunderstorms got moved further and further back.fletc3herhttps://www.blogger.com/profile/17218588976016685854noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-79812296206475571112015-08-12T18:04:42.194-07:002015-08-12T18:04:42.194-07:00^^^ Wholeheartedly agree with my colleague Chris ...^^^ Wholeheartedly agree with my colleague Chris Burke's comments above. The "upgrade" to A2 crushed our forecasting tools in Portland as well, and it took a whole year to recover...mostly. That said, Cliff's comments are spot on as well imo. MOS relies on climatological norms, and this has certainly been an abnormal year in many respects. The statistical equations going into MOS are probably making a lot of assumptions that are usually okay, but are not trivial this year.<br /><br />By the way, gotta stand up for our neighbors up north... based on the scoreboard above, NWS Seattle actually "won" versus TWC/wunderground. RMSE 2.727 for NWS; 2.872 for TWC. If NWS Seattle eliminated their -0.6°F bias, it would have been a blowout! :) Impressive considering the technical challenges they are facing, which I know all too well.

Just moved back in March 2015. I will tell you I kissed the ground when I got back, excited to be out of the arid hot smoggy wasteland of California, back to cooler wetter weather and green landscapes, and vowing to never move away from Washington again. While I stand by that you can imagine my dismay when I discovered the horrible hot, dry and brown conditions have extended up here and further beyond.

You'll never get Cliff to stop calling 88 degree weather, in a town with very few home air conditioners, "nice". Or to refrain from saying that it's going to be very warm, so "Enjoy", as opposed to Hang In There or Buck Up or "try not to die in your apartment".<br /><br />Actually, the parenthetical "weather is much better (generally warmer)" is a small victory, or I'm claiming it as a victory anyway. Finally a tiny bit of acknowledgement that warmer does not necessarily equal better for a large portion of his audience.

Implementation of this system around the weather service has been disastrous and Seattle is no exception. Among other problems, the MM5 models have not been available to us when we are editing grids, and many of the other temperature guidances we have used are either not available or are somehow damaged. Recovering from this "upgrade" will likely take several more months. As usual in the NWS, each office has to figure every computer problem out for itself, with no help from our regional or national offices. I am personally shocked that our Max T forecasts seem so bad. To lose to persistence is indeed poor--note that in the spring forecast contest our forecasts crushed persistence, like everyone else's.Chris Burkehttps://www.blogger.com/profile/17518534777541600347noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-14668090043500476582015-08-11T11:17:35.024-07:002015-08-11T11:17:35.024-07:00Is that online tool created by Luke available to t...Is that online tool created by Luke available to the public?

Might just be a microclimate effect. But there have been lots of days where the forecast says 75 and we end up at 82, the forecast says 82 and we end up at 90, or--that one terrible Sunday--the forecast says 90 and we end up at 98. Plenty of times I've checked one of the weather apps in late afternoon, and it says the high today was to be X, while prominently displaying the current temperature of X + 6 (or 7 or 8...).<br /><br />I'll give Cliff credit: we did wake up to rain yesterday, and more looks to be on the way, albeit in spotty showers. But when it's hitting the high 80s with blazing sun in between those rare showers, the garden still dries right out. My withering drought-tolerant plants and I agree with Cascadian Engineer: this is not what we'd call "nice" weather.
