First of all, it's 75* outside here, not 65. Secondly, if you're cool with this weather, I suggest a move to Florida.

If it's not going to snow, I'm quite happy with 30* and sunny.

Negative. If it is going to be 30* then it needs to be snowing. Otherwise it is a waste of cold air. If it isn't going to snow, then 70 and sunny is perfectly fine by me. :sun:

We get warm weather almost every yr in the cool season several times.

I don't really care about the next 3-4 weeks. Those events are usually small or mix. 12/20 to 2/20 is the period where I hate to squander lots of time on awful patterns, even though I know we will endure some bad patterns during that period. 88% of our snow falls after 12/20

It's not even met winter...people are freaking out on Facebook. If it's like this in mid December maybe I'll start to be worried but even then not really...

Not sure if you remember December 2005, but we got a +PNA/-NAO for a 3-4 week period and we did score, but it was relative to the period so tempered by climo. We got 4-5 events but all were very minor or mixed except for 12/5-6. I think I got 6 .5" for the period with the biggest event being 3.25". The 12/9 event was just over 2" then changed to sleet and the other 3 events were car toppers. Then we torched. Forever and ever and ever. If we had that same period from 12/20 to 1/20 we would have doubled our snow probably. We are wasting an unproductive period. I haven't gotten a legit legit November event since 1989. I couldn't be happier we aren't wasting a block right now. That would be a travesty. 6

I love snow but also like 65 with sun now that the tree have pretty much shed their leaves. The massively positive ao and nao sure aren't good for snow anytime soon even with the pna going positive.

Yep - it's beautiful when the sun can shine through the trees to make basking in it a real pleasure. If we didn't have people working on the house, I'd have probably grabbed the clubs and played a round today.

I'm OK with things staying normal to above normal for a few more weeks. Like zwyts said, we're only "wasting" a period during which we rarely see snow of consequence. Let it torch for now, and we can make up the difference around Christmas and into the New Year.

Todays highs:

IAD: 70* A new record. Old record was 68* in 1976

BWI: 71* No record. the record high for this date in 1896 was 74*

DCA: 72* No Record. The record high for this date in 1896 was 75*

MRB: 68* No Record. The record high for this date in 1976 was 71*

in 1976, a lot of cold must have followed because I remember all of DEC as being unrelentingly cold

70", damn thats a nice snowstorm. Too bad Frederick got screwed I guess we're the new DCA, slightly lower totals than surrounding areas.

On November 27, 1976, the high temperature was 65 at DCA, and did not reach or exceed that until February 23, 1977, when the high was 72. December 1976 was the 34th coldest December in DC history, with an average temperature of 35.5 degrees, followed by the fifth coldest January ever, at 25.4 degrees. It then warmed up to 38.4 degrees in February 1977 (45th warmest February ever). However, there is no analog between November 1976 and this November, as November 1976 was cold overall, at 43.0 degrees (13th coldest November ever), as opposed to 52.2 so far this November.

Must be slow news time around there. BFD it hit 70... Dulles records are broken every other day. ;)

It was in the 50s in the valley east of San Fran today. Cooler than the coastal areas. Damn fog.

The end of the 1st week in December intrigues me a bit. Aside from models, it's my personal interpretation of the atmospheric progression that leads me to believe there should be a weakness near us during that time, and in a favorable trajectory in giving us a shot at accumulating snowfall. It's a week out but I think we have a good chance at a wintry event within the next 10 days.

I think models should begin to pick up on this system within the next 3-4 days, GFS as usual just past it's resolution loss gives it that big "cold front" look, Euro is sniffing it out a tiny bit, but I think I can see the progressing weakness that should lead to a low tracking from the gulf region up/near the east coast, bringing us our first chance at a significant winter event. Either that or it cuts inland a bit.

Really hope I don't end up looking like a massive blowhard for this call, but Ji cancelling winter as usual seems to lead to something nice down the road :snowman:

6z GFS should be to your liking right about the 6th of December. I don't know if you meant the end being after the first seven days or the first weekend, but anyway, there's winter weather in that solution.

I can't wait until someone starts the December thread because this one has been pretty bad.

65 with sun is never too warm!

+1

Agreed. It's foolish to expect snow before Christmas in DC. Anything that falls before then should be considered a nice bonus.

I thought so too until I checked soundings (ya' know it's boring when you start checking soundings at 180 hrs+)

anyway, too warm at the surface (at least east of the mts), maybe ending as some flakes, that's all

and before anyone says don't take it verbatim, I am; I am taking the qpf and the temp profile verbatim because we need both

otoh, it is fair to say it's a "threat", but not much more going by the 6Z GFS

Mitch, I'm proud of you. I always thought you the eternal optimist when it came to snow. I don't think the 06Z run looks good for snow. The pattern is a bad one.

sadly, the reality that we're gonna' have to wait until after Christmas has set in

anything that falls before then will be the fluke of flukes it seems

Is it really that bad though? We only have about a 12 week shot around here. I never count March in the snow season. It's nice to get March snow and all but it rarely sticks around for long and rarely happens.

Out of the 12 week window we never have a full 12 weeks of favorable pattern anyway. If we're gonna throw 3 weeks down the toilet, it's better to take it on the chin at the beginning.

If things look like crap a month from now then I'm joining Ji.

I don't think I'd put any faith in it even if everything looked great. I have zero confidence in any model solution beyond about 5 days. They may be somewhat skilled at predicting a general pattern of weather, but they don't seem too good to me at predicting "real" weather at that time frame.

He had mentioned he thought that there might be something interesting at that time frame. That's really the only reason that I even posted that.
