TT-SEA Posted September 15, 2017 Report Share Posted September 15, 2017 12Z ECMWF control run shows some warm air during the 11-15 day period to end the month. This is the 5 day mean... 850mb temps.

Phil Posted September 15, 2017 Report Share Posted September 15, 2017 God f***** D****T.It's not a stable pattern like early September, though. Verbatim, the enhanced convection only takes ~ 12 days to cycle through the Pacific, and we're far enough out that this could reverse completely. Just an interesting trend given we're in a state that would statistically favor less Pacific convection going forward, rather than more.

Geos Posted September 15, 2017 Report Share Posted September 15, 2017 Not sure... it might increase the snowfall for all of King County. On the other hand... without that gap in the Cascades my area would see much less snow and be dependent entirely on elevation. Yeah it be more like how Portland and Vancouver gets there big snows with the east flow going through the mountain gaps.

If you are going to bust due to something unexpected coming up, it will always be towards things being ridgier than anticipated for us. Not troughier. Your ridge forecast usually verify and then some, with little to no issues. 1 Quote Link to comment Share on other sites More sharing options...

It's maddening, tbh.Seems like it would be an easy thing to correct for, but maybe there are nuances I'm not aware of. So if things do get ridgy the last part of September do you seeing it as being short lived overall? I thought for sure ridging would stay off to our northwest for the rest of the month given the progression. Certainly more sunny and even warm days but nothing like the big fat ridge the Euro parks right over us at days 9-10. Seems like a return to the pattern we were seeing before what you were saying was a big shift. Quote Link to comment Share on other sites More sharing options...

Then there will be a big trough in the first part of October and then there will be a prediction of early November ridging which actually come later in October.

epiceast Posted September 15, 2017 Report Share Posted September 15, 2017 The new EPS weeklies do revert to the ridge west/trough east pattern next month. Looks like some Pacific convection, though it appears to be transitory in nature. Will be interesting to see how it unfolds. Looks like a difficult pattern to forecast either way with tropical cyclones everywhere.Would be nice to get some backpacking weather in October after Snowy the bear put out all the fires.

Phil Posted September 15, 2017 Report Share Posted September 15, 2017 Seems like it would be an easy thing to correct for, but maybe there are nuances I'm not aware of.It's more complicated because it's not just timing waves but gauging the synchronization of waves of different phase periods/frequencies. It's interesting, as I'm not the only young forecaster who struggles with a slow bias. I don't know anyone with a fast bias, though.

Seems like a return to the pattern we were seeing before what you were saying was a big shift.The shift is absolutely real, but it's also lower frequency so there will be bumps and blips in the trend towards -PNA/-NAO. Look at the high latitudes right now..for the first time in what seems like forever, that Black Hole over the Hudson Bay/Greenland has been replaced with a big anticyclone. The subtropical NPAC is also developing the -PNA loading pattern. The transition is a complicated process though..it will take more than a few weeks to complete.

I don't know whether they're correct or not, yet. I've been forecasting a jet extension/Aleutian cyclone and intermountain west ridging starting during the second week of October. Maybe it'll happen during the first week of October, or maybe something else will happen.
