TT-SEA Posted July 27, 2016 Report Share Posted July 27, 2016 All of its busts have involved overestimating or underestimating the marine layer, see the frequent warm busts @ PDX. There is no "rule" or inherent cold bias involved. SEA will probably come in at 78/57 today. 78/59 in the books. A +2 day.

ShawniganLake Posted July 27, 2016 Report Share Posted July 27, 2016 Nice warm spell on the 00Z GFS next week. Overall, looks pretty seasonable through the entire run. A little cool here, a little warm there. Nothing too crazy. Quote Link to comment Share on other sites More sharing options...

Geos Posted July 27, 2016 Report Share Posted July 27, 2016 Still a warm one today despite the AM marine layer. High of 80° here. Was a beautiful evening to be outside. 85° in the point for Thursday.

ShawniganLake Posted July 27, 2016 Report Share Posted July 27, 2016 The 6z really watered down the incoming trough for the weekend. Quote Link to comment Share on other sites More sharing options...
TT-SEA Posted July 27, 2016 Report Share Posted July 27, 2016 The 6z really watered down the incoming trough for the weekend. No... its really cold. 06Z run shows both days around 14-15C down here now. Marine layer will actually keep it cooler down here per the ECMWF. Both weekend days start out very cloudy and it will probably last into the early afternoon like yesterday. Both afternoons look sunny though with highs probably close to normal. Monday is looking warmer. Not seeing signs of a cold August right now.

Jesse Posted July 27, 2016 Report Share Posted July 27, 2016 06z GFS leaves the incoming troughing unchanged, with 850mb temps plunging to a chilly 5c down here. That's nearly 10 degrees below average for upper air temps in early August.The ensemble mean stays below average the entire run too. Great run. This will get us off to a good start for a cool August.

TT-SEA Posted July 27, 2016 Report Share Posted July 27, 2016 That image is not right or not updating. The 06Z run clearly shows 850mb temps of 15C both weekend days in Portland. Here is Sunday afternoon: Also shows 850mb temps around 20C by Thursday: Quote **REPORTED CONDITIONS AND ANOMALIES ARE NOT MEANT TO IMPLY ANYTHING ON A REGIONAL LEVEL UNLESS SPECIFICALLY STATED** Link to comment Share on other sites More sharing options...

Jesse Posted July 27, 2016 Report Share Posted July 27, 2016 You're screwed.

TT-SEA Posted July 27, 2016 Report Share Posted July 27, 2016 12Z GFS shows basically the same as the 06Z run for the weekend. Around 15C just east of Seattle down through Portland on both Saturday and Sunday. That German site must have been using the 06Z run from the previous day. Best to just use that site and not actually look at the real GFS runs at all.

Not sure what the difference is. It was showing the previous day's 06Z run... you can tell by how cold the operational run got in that image over the weekend. Nothing close to what the run from last night was showing. Also illustrates the models trending warmer now.
