smokeybandit Posted October 31, 2016 Share Posted October 31, 2016 I just committed today to have new windows installed, probably late November/early December. So right around that time expect a really cold spell to come through Link to comment Share on other sites More sharing options...
Rtd208 Posted October 31, 2016 Share Posted October 31, 2016 Don't see a vendor thread so I will just post this in here. Larry Cosgrove released his outlook for winter 2016-2017 and its not good if you like cold and snow although confidence levels are not particularly high. He is also going with a very warm December which seems to contradict most outlooks. https://groups.google.com/forum/?hl=en-US#!topic/weatheramerica/PeySp4BFjEA https://groups.google.com/forum/?hl=en-US#!topic/weatheramerica/bBiWzmLaLSA https://groups.google.com/forum/?hl=en-US#!topic/weatheramerica/gbv3LItS4Yo https://groups.google.com/forum/?hl=en-US#!topic/weatheramerica/udrthzDZ-Dw Link to comment Share on other sites More sharing options...
EastCoast NPZ Posted October 31, 2016 Share Posted October 31, 2016 Jeezus, if we have to wait again to Feb for winter, then we can skip it totally, as far as I'm concerned. I hope Cosgrove is very wrong, but with the persistence of the heat this year, I fear he will be right. Link to comment Share on other sites More sharing options...
RIC_WX Posted October 31, 2016 Share Posted October 31, 2016 Cosgrove uses 1995 2x weighted in his outlook. That is pretty telling. Point is, 1995 in the means wasn't a particularly cold winter in a lot of places. In the mid atlantic...conditions were a lot like they have been recently...where you get 48 hour + intrusion of cold air, followed by a big backside warm up. Thanksgiving weekend was a great example of this, it started very cold and ended mild. As the season progressed, the cold intrusions lasted a little bit longer / stronger and there were plenty of backside warmups. It's remembered as a benchmark winter mainly because when it got cold it was very cold, and seemingly almost always timed with an accumulating snow storm particularly in January / February. For this analog to have any continued validity for me November needs to get cold in the means at some point. IIRC, there was a pretty big flip after the first week or so of November 1995 after which time departures were biased towards cold despite the warmups on the backside of every cold air push. If November 2016 looks anything like October 2016 we might need to toss. So, in that respect I think the next couple weeks are pretty critical. I do wonder how many of us in the forum have first hand knowledge of the 95-96 winter...obviously many do, but as it has been 21 years I have to assume there are plenty who don't due to age, or were simply living outside of the Mid-Atlantic at the time.

It was cold at the end of October in 1995. On Halloween weekend there was widespread snow from Kentucky, Indiana, on through WV and much of Virginia. I don't remember 95-96 ever having too many extended warm periods, or dry periods. Helluva winter and cold way up into spring. Link to comment Share on other sites More sharing options...

Helluva winter and cold way up into spring. Pretty sure for most Mid Atlantic reporting stations, October 1995 was biased warm and November cold. The averages today are higher, and the departures in October 2016 higher still from present averages, so pretty sure October 2016 was in fact warmer in absolute terms. As for "extended warm periods", that wasn't the point. They were not extended, but potent. All of that January blizzard melted pretty suddenly a week later and caused flooding. This is representative of the swings we are seeing in the pattern now, which again as the season progresses could continue and in fact become more potent on the cold side assuming the analog has any validity. If November averages warm, it's an indication this particular analog probably deserves less weight. Link to comment Share on other sites More sharing options...

CAPE Posted October 31, 2016 Share Posted October 31, 2016 With Cohen talking up record WAFz and possible unprecedented PV split in early November, and the colder, blocky 500 mb pattern showing up in the LR means, how can the MA not see significant snowfall before December?

Bob Chill Posted October 31, 2016 Share Posted October 31, 2016 Either a coincidence or connection, the pattern showing up on the ens towards mid novie are very nino'ish and not looking much at all like a nina. Enso influence won't really show its potential until December but for right now I question the early part of winter behaving like a traditional nina. On another note...after pretty much crashing into negative territory, the +PDO has been making a comeback all month. If the persistent trough in the GOA retros to a classic aleutian low/-epo ridge like the GEFS has been showing then the move towards a +PDO will continue through Nov The shift to a nina has done nothing but under perform all summer/fall. IMHO- I think there is more risk of a nino hangover type of pattern during the first part of met winter than anything. Just a guess. Link to comment Share on other sites More sharing options...

According to the data that I took a quick look at, November was about -5 here, December -2, January -2, Feb -4, etc. If you averaged data from multiple stations in the coastal plain, I think it would be a little less pronounced. Then again, if we could match absolute temperatures from 1995 vs. present day warmer averages, it would probably look more striking. Either way, the oscillating pattern we are in every few days is I think typical for seasons without a strong enso signal. Without persistent blocking I would expect the stronger the cold air mass, the more quickly the backside moderation on the return flow. Again, how this develops in November is telling if the 1995 analog has validity or not, which was the point of my comments, and noting that despite Cosgrove's overall warm look he was still giving disproportionate weight to this season and it could be correct...or not if the blocking never develops.

Yea, you wouldn't expect the pac to have that look. Maybe Nov isn't unusual but if that was Dec it would definitely not indicate a nina in control. 95-96 is on the d11+ analog list along with a few other weak nina's but there are some notable mod/strong nino's showing up.

I don't think 13-14 or 14-15 had strong enso signals with both hovering around the plus/minus 0.5 area, but both were pretty consistently cold IIRC.

That 1974 date was a few days prior to one of my favorite storms growing up. I know Mitchnick recalls it. A real stemwinder and the first time I saw thunder snow (in western Maryland.). Really dynamic system with huge precip totals accompanied by plummeting temps. Ended up with 18"+ in the high elevations. 3" rain totals in the metros, iirc.

There does appear to be a pattern flip mid-late November. However, the source regions of Canada are very warm and it may take time for "cold" to actually build and deliver here.

Going super simple...2 really easy ways to fail: 1. Simply missing out on some good setups when they are there and ending 50-75% of climo with the cliche "we could have had a good season if..." 2. Despite generally favorable blocking the cold is locked over on the other side of the pole or the Pac sucks and we never get temps right regardless of storm chances (00-01 & 12-13 are prime examples) I'm rather indifferent this year but more bearish than anything else. If we get blasted then great. If we stink it up then it shouldn't surprise anyone. We are the MA after all and we've been on a bit of an historic heater the last 3 years.

RIC_WX Posted November 1, 2016 Share Posted November 1, 2016 In past seasons, we've complained about "wasting" cold in November when climo says it's not likely to snow anyway.

With the big if being the ridge in the west continues to retro then cold air would have no problem building in central canada and hp over the pole could potentially draw from siberia. Total speculation on how we "could" extensive cold into the conus towards the end of the month. OTOH- if the upper MW and all of Canada build some snowcover late month then that is always a good thing down the line. Nov isn't important for us near the cities though. We have to root for favorable in early Dec and that's so far out there that I have no opinions. Link to comment Share on other sites More sharing options...
