Suddenly @JetTip alerts became chatty with diversions from SEA to PDX. A quick check of weather in Seattle shows low IFR snow/mist, 3/4sm visibility. PDX is MVFR but better: 4sm visibility, 1700ft ceiling, rain/mist. Travelers probably didn't plan to hear "Welcome to Portland" but will be safe on the ground while they wait. #aviation #travel #weather #avgeek
Here's why it's snowy in Seattle and rainy in Portland. A temperature difference indicates and prog chart confirms a front between them, with Seattle on the colder side of it. Even though some planes are diverting, some are making it into SEA. @JetTip indicates there were 20 diversions at #KSEA, 8 of them to #KPDX. But at the same time I checked ADS-B and saw an Alaska 787 landed at SEA on its first attempt. (If that one had diverted, cameraπŸ“· was ready.) #aviation #travel #weather #avgeek #PNW
