mitchnick Posted September 15, 2015 Share Posted September 15, 2015 Idk if this link has ever been posted here, but Ginx snewx over in the NE thread linked it in their winter thread. It has some great research info and will really save some time for those interested in looking back for potential analog years. http://www.wrcc.dri.edu/enso/uspmaps.html Link to comment Share on other sites More sharing options...

mitchnick Posted September 15, 2015 Share Posted September 15, 2015 If DCA is anywhere close to 30, it'll be a damn good year, in between the parts where we torch and cope with rainers. plus, if DCA can come in with that much "officially", you know places like IAD and BWI are going to be 35"-40" Link to comment Share on other sites More sharing options...

Was mostly just joking around...haven't really looked at anything yet, but will start in the next few weeks...Can't say I'm terribly enthused about a strong region 3 based nino with great uncertainty over whether the atlantic will be any good... I'd sign on the dotted line right now for what we had February 14th through early March. Eta: but I would not sign for things to play out like Matt predicted. At least wrt snow events. Spread out my 28. I'm chasing greatness..winter is pass/fail for me this winter...Hecs - Pass, No Hecs - Fail Link to comment Share on other sites More sharing options...
Bob Chill Posted September 15, 2015 Share Posted September 15, 2015 I'm going normal to below normal temps in December because not a single person is right now. At least for BWI/IAD anyways. If DCA ends up only +2 or something it will be a considered a cold month outside of 495. Link to comment Share on other sites More sharing options...

Fozz Posted September 16, 2015 Share Posted September 16, 2015 Pretty much wall to wall winter. DC area folks got shafted in mid December if I remember correctly, but everyone was in on the good stuff early January on. Cold, snow...man we had a nice run. It was an excellent winter and I'll remember it very fondly for years to come. Snowed almost every week and brought some of the coldest outbreaks in decades.

DC area folks got shafted in mid December if I remember correctly, but everyone was in on the good stuff early January on. Cold, snow...man we had a nice run. Yup...early to mid December screwed us in comparison to farther north and west. Here are my notes from that period: November 26: T - Pingers in the early AM before the deluge November 27: T - White rain with the wraparound December 8: 1.25" - A few hours of light snow followed by sleetfest and pouring freezing rain overnight December 10: 2" - Hype storm didn't live up to expectations (couple degrees too warm) December 14: T - Awful storm - poured rain with a few sleet pellets for a bit December 17-18: 0.25" - Overnight vort passage = dusting on everything Early January saw the flip to cold, and MBY got 10.5" that month. Mid February through March was our wheelhouse that year. Seriously backloaded, with a March like pretty much nothing we ever see in these parts.

Let's do this.... We have September's runs of the Euro seasonal, UKMet, and JAMSTEC all pretty much saying the same thing for D-F, around normal temps with above normal precip (Euro seasonal cools it off some more in the J-M period too.) The Eurosip, a multi-model forecast system, has us a little warmer than the Euro seasonal, but it includes the CFS2, which is the outlier being much warmer than the other models as it places the GOA Low anomaly further east than the other LR models; remove the CFS2 from the Eurosip average, and, in all likelihood, you have something much closer to the other 3. So we're left with the question, what's WinterWxLuvr going to do when he finds out his favorite model busts? Idk, but I don't want to be around when it happens.

Bob Chill Posted September 16, 2015 Share Posted September 16, 2015 Of course I like the UKMET and JAMSTEC seasonal looks but if there is any flag that I see on the runs it's with the SSTA plots. They both show a classic +PDO with the warmest anomalies in the NPAC banked right up against the west coast. It's pretty much the textbook look. The reason both show that is due to the general H5 pattern depicted with the low anoms further west and ridging right along the coast. SSTA's would end up looking like that if that type of pattern dominated met winter. However, I think it's going to be an uphill climb to that look come the end of Oct. Certainly by the end of this month given what ensembles are painting through the end of Sept. That's our wildcard irt temps at least. Just have to let things play out. I don't think any seasonal model is right or wrong. CFS may get bashed but it's showing a definite possibility. Link to comment Share on other sites More sharing options...
JoMo Posted September 16, 2015 Share Posted September 16, 2015 But, CFS v2 has the same +PDO? The difference comes more in where the ridging is placed farther east with the CFS v2. Link to comment Share on other sites More sharing options...

Being the honest scientist that I am, let me cherry pick one for you. Now, granted the GOA isn't exactly what the UK and JAMSTEC show (but we have time), but this SSTA does look real close to what they are showing in the equatorial PAC.

Now, granted the GOA isn't exactly what the UK and JAMSTEC show (but we have time), but this SSTA does look real close to what they are showing in the equatorial PAC. As far as the pac goes, our winter hinges on where the low height anomalies persist on the means through the winter (stating obvious). So far the CFS is the only one to show things places a bit too far east but even the other seasonals show things close enough that even a minor shift would be bad news. I'm not worried or invested in anything either way. I know exactly what we need and there is not way to really know until we are well into the season. Even if December sucks it still doesn't mean Jan and Feb will. Same goes if December is tasty. Things can easily go the other way. I would be more unlikely for the npac to suck or be great for the entire winter anyways. The one thing that has my interest is the possibility of the Atl cooperating. Summer or not, this is an impressive run. One that could very well have implications going forward. The limited history we have with summers dominated with a -AO look pretty nice and this one has been one of the stronger cases if there is some sort of connection. 97-98 had good blocking but unfortunately all it could do was force pac air down from Canada instead of continental air. In the end the winter sucked of course but it wasn't dry and had plenty of coastals. Matt has said for years that he's hoping for a big nino and just let the cards play out. We got his wish coming. I'm pretty optimistic overall that we end up with at least 1 memorable storm. Link to comment Share on other sites More sharing options...
