The stagnations can last for weeks. Storm forecasts abound, always placing activity at 5 or more days away. Such as we have going on right now. Fog, burn bans, inversions, and cold, dead air at the bottom dominate. It happens during El Nino, La Nina, and everything in between. It takes a huge bite out of rainfall, and especially snow in the mountains. Meanwhile there are breathless headlines of mud slides in southern California or blizzards such as those that came in almost every day last year from Boston. There was an episode we had a couple of years ago that nearly brought us a rainless December. January and February are often no better. At least Cliff called this one right when it started last week. I hope it isn't still parked over us at Christmas.Rickhttps://www.blogger.com/profile/09238400532361960301noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-72090869884666077692015-11-28T20:34:20.909-08:002015-11-28T20:34:20.909-08:00Usually when an inversion affects the area I can s...Usually when an inversion affects the area I can see atmospheric evidence of it in our Wedgwood (NE Seattle) neighborhood. Not this time though. Fog did form south and south west of here but didn't quite make it over the ridge just west of us. <br /><br />For now I'm focused on the possibility of a wind event in the Thursday / Friday frame, although the weather models are dueling that one out. Probably just a 25 - 30% chance. I'll wait for you to weigh in Mr. Mass as to that likelihood. Cyclogenesis is right up your alley.<br />John McBridehttps://www.blogger.com/profile/09503331313775640577noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-19289509817567639072015-11-28T12:41:58.084-08:002015-11-28T12:41:58.084-08:00No fun ☹️No fun ☹️Gpacharliehttps://www.blogger.com/profile/07899629492778221889noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-19097121831276106222015-11-28T12:22:20.550-08:002015-11-28T12:22:20.550-08:00Cliff, I have 2 questions, both relating to invers...Cliff, I have 2 questions, both relating to inversions.<br /><br />First, why does King county- the population center- have better air, and fewer burn bans, that both Pierce and Snohomish? It doesn't make sense to me. If it's the wind, why would there be more wind?<br /><br />Second, why does southern New England, where I come from, have plenty of wind during clear winter weather (as I remember, the wind pretty much howls all winter, clear or not, therefore it's not inversion-prone) whereas here in WA we usually seem to go stagnant as soon as the high pressure forms over us?<br /><br />Thanks, AnselAnselhttps://www.blogger.com/profile/13835758313287462921noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-79294452156547755282015-11-28T02:40:38.769-08:002015-11-28T02:40:38.769-08:00Yeah, my asthma has been bad the past few days.

As we ascended to ~ 1000' the temp increased to 37°f which was the opposite of the norm.Gpacharliehttps://www.blogger.com/profile/07899629492778221889noreply@blogger.com
