Since warmer air is more buoyant, it will be the air mass to rise up over the cooler air.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-17128789434394617642009-01-09T17:31:00.000-08:002009-01-09T17:31:00.000-08:00Thanks, anonymous--I`ll check that site out.Thanks, anonymous--I`ll check that site out.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-81213085198591406822009-01-09T13:57:00.000-08:002009-01-09T13:57:00.000-08:00Climo Man, do you ever post at Westernusawx.com? ...Climo Man, do you ever post at Westernusawx.com?

Historically, there have been quite a few Seattle winters that have had a cold and/or snowy start,a mild uneventful respite in the middle,then another--although briefer-- cold spell in February.The winter of 1955-1956 is probably the most outstanding example.<BR/> By the way,for those who like me are interested in historical weather events and climatology, this week is the 100th anniversary of one of the most severe arctic air outbreaks in Seattle since records began in 1890.From Jan 5th through the 12th in 1909,the temperaure remained at or below 25 degrees F for eight consecutive days,a record that still stands.This event is even more impressive by the fact that the weather station at that time was on the roof of the Alaska Building on 2nd and Cherry, near the balmy waters of Elliott Bay.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-25623291194521344942009-01-09T11:56:00.000-08:002009-01-09T11:56:00.000-08:00Cliff, I'm curious to learn, and I'm sure someone ...Cliff, I'm curious to learn, and I'm sure someone has done the calculation, how many acre feet of water fell during this storm and fall on average from these pretty much annual events. I grew up in Issaquah in the 1950s and '60s and it seemed that our farm was swept with these events at least once a year, and frequently twice. A lot of rain would fall. I suspect that the number is in the hundreds of thousands, but that's obviously a simple "guest-imate."<BR/><BR/>Does anyone know what the record setting event has been? Some of the events of my childhood seem in memory larger than recent events, but records have frequently shown my memories to be wrong and I suspect the same is true in this respect.<BR/><BR/>ThanksJohn McBridehttps://www.blogger.com/profile/09503331313775640577noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-31416142323432136712009-01-09T11:23:00.000-08:002009-01-09T11:23:00.000-08:00Like Cliff said, the cold Alaskan air will not go ...Like Cliff said, the cold Alaskan air will not go to the PNW. It is going to the midwest and East. Chicago will be below zero, and even NYC may have a morning low below zero for the first time in 14 years.<BR/><BR/>But, winter is still young, and a lot of experts are saying we could have another arctic outbreak in late January or early February. One of them is Ed Berry, who correctly forecasted arctic air for us four weeks before we got the cold in December.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-7419913638649186012009-01-09T11:06:00.000-08:002009-01-09T11:06:00.000-08:00thank you sir!thank you sir!Devinhttps://www.blogger.com/profile/11320858693144342031noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-47880429423927049762009-01-09T11:04:00.000-08:002009-01-09T11:04:00.000-08:00Devin...no Alaska Air..the ridge will protect us.....Devin...no Alaska Air..the ridge will protect us..cliffCliff Mass Weather Bloghttps://www.blogger.com/profile/13948649423540350788noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-54788563218163863142009-01-09T10:58:00.000-08:002009-01-09T10:58:00.000-08:00Cliff, please answer our question about the cold A...Cliff, please answer our question about the cold Alaskan air!
