I take it everyone had a safe and fun New Years Eve and is ready to rock 2015 like.... 2015! As one might imagine, my silence from this page after getting excited about the potential for snow fall could only mean one thing... no I did not die. The silence was due to the fact that there is nothing going on but a strange yellowish orange glow in the sky (that is hurting my eyes lol) and the potential for snow has all but vanished. Yikes. Instead we have the complete opposite... The Pineapple Express 2.0 (I will explain later) will dominate our weather for the next 10-14 days and keep our temps warmer and keep us wetter. Ok, so I dubbed this pattern 2.0 simply because of this... A typical Pineapple Express would have the Jet stream dip down to Hawaii and then go back north and aim it for the Great Pacific Northwest. This would be a true flow of moisture straight from the tropics bringing all low pressure systems over us. In this version, a Low pressure system is formed nearly off the north shores of Hawaii and goes due north and south of Kodiak Island. It will sit and park itself off the Washington, Oregon coast line... but still north of Hawaii. It is the arms of moisture, turning counter clockwise, that will bring moisture into our area. So, not a true tropical system, but a system with warm moisture none-the-less. Before this big system comes, we do have a system coming from the north that could give us a few showers tomorrow night, but with the predicted westerly flow of air, and cloud cover, we will warm up about 10 degrees or more overnight eliminating any chance that this smaller system could bring snow. The lager system, will come probably Sunday night, and last about 10 days giving us off and on heavy rain. Fortunately, I think will will see a day or two of a rain shadow as the moisture will initially be traveling southwest to north east, but during the peak, moisture will travel south to north. One model says our peak moisture will be on Wednesday, but it calls for over an inch of rain. That would make it the wettest day of the year... and last year too. ;) It is at this time that this large system will start moving east... but another Low pressure will take its place. About next Friday, this system will also move east towards Canada. It is at this time that weather models become... lets say... not to reliable so we will leave it at that... but the patter does look to repeat itself. If all this goes down, I believe this will be one of the wettest Januarys in a long long time. So in short: No snow. Look for a very wet week starting around Sunday with temps going back to or slightly above seasonal norms; upper 40s for the highs and upper 30s to lower 40s for the lows. *It is worthy to note that this is purely just my observation based upon the weather models available to me. No input from NWS of Seattles scientific weather discussions.
