Jesse Posted March 8, 2020 Report Share Posted March 8, 2020 None that I’ve been bullish over. This would be the final warming, technically. Where the vortex breaks up and is replaced by an anticyclone for the warm season. A “dynamic” final warming is analogous to a SSW, for all intents and purposes, though. I understand the difference, but mechanically they are fairly similar. 1 Quote Link to comment Share on other sites More sharing options...

Phil Posted March 8, 2020 Report Share Posted March 8, 2020 I understand the difference, but mechanically they are fairly similar.True. At least if it’s a dynamic final warming, as I’m sure you already know. Non-dynamic final warmings aren’t all that interesting though. At least to me. Just withers away as solar radiative forcing alters the photochemically modulated boundary conditions through which thermal winds/etc operate under. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Phil Posted March 8, 2020 Report Share Posted March 8, 2020 The vortex is really just a chemical tornado, driven by the insolation gradient. Change that up and it can’t exist. Which is why I’m sort of bullish here. The vortex will have to die at some point. And given its anomalously potent starting point leaves room for impressive wave dynamics (not to the ongoing O^3 depletion/night jet feedback loop still present to midwinter levels) I’m buying into the analogy “the bigger they are, the harder they fall” at this time of year”.

Phil Posted March 8, 2020 Report Share Posted March 8, 2020 But how this relates to PNW cold/timing of such depends on the EA-AMM/response from the tropics/MJO and the wave-cycle itself as seasons are changing. Tough call. If there’s a cold air release, I think it’ll happen in April, or the end of March. Would not shock me if there’s some serious late season cold somewhere next month, but exactly where is tough to pin down this far in advance during the seasonal transition.

Phil Posted March 8, 2020 Report Share Posted March 8, 2020 12z Euro is a little wetter than the FV3 but that's not saying much.For whatever it’s worth, the ideal pattern to produce the dynamic final warming and maybe shake up some trends going into this seasonality change would be drier/meridional over the West during that process. So that might technically be a good thing. Wouldn’t be permanent. That zonal pattern a few folks were semi-excited about during January ended up failing for the same reasons the inverse may succeed.

snow_wizard Posted March 8, 2020 Report Share Posted March 8, 2020 Nobody is going to talk me down from this. I have a feeling the coming few weeks are going to ooze 19th century. I haven't been this stoked about anything this time of year in ages if ever. The potential is there for a number of cold duration and intensity to fall this month and maybe into April. The -5 EPO being forecast the EPS is reason enough alone to know something highly unusual is unfolding. It will be interesting to see if intrusions of chilly continental air even extend well into the spring. I'm going to enjoy all of the unseasonably cold mins coming up, and snow is a definite possibility somewhere along the line as this unfolds. Quote Death To Warm Anomalies!
