Today was gorgeous, loved it outside. Got more yard work done, now everything is done but turning off the water outside. Got another 2 weeks till I take care of that. Got to 72 here for a high, breeze made it even nicer out there. Rather have this wx now than say in late December.

I'd take 72 and sun at any time of the year.

To each his own, of course.

Through the first 14 days of November, the following years had 0.06" or less of precip

2005

2001

1964

1931

1918

1917

1878

1874

The final precipitation totals (in inches) for each of those months were as follows:

November 2005: 1.92

November 2001: 0.55

November 1964: 1.42

November 1931: 1.01

November 1918: 1.48

November 1917: 0.53

November 1878: 3.03

November 1874: 2.08

Average, 8 years: 1.50

So, the average of those eight years is very similar to what would be expected based on multiplying 16 (the number of days remaining in November) by the average of .093 inches of precipitation per day that has occurred in DC in November during 1871-2010. Let's see how close we come to that average this year.

It's 70 degrees at midnight with a warm southerly wind ahead of this line of showers coming in. It's hot in the house even with the windows open...I'm temped to put the A/C on. The line of showers is moving in pretty fast. NWS says to expect wind gusts of 45 mph with it. Doesn't appear to be any lightning with it near here. Feels like a summer evening outside.

Wxrisk has been a disaster on facebook spinning his original bad forecast of a major pattern change by the 15h and then by Thanksgiving....etc. He is acting like he saw this all along with is complete BS.

I guess when you control your messaging and followers, you can spin anything you want and never be wrong

Actually, I think DT has played it pretty straight down the line. Yes, several weeks ago he called for a pattern flip by the 15th. Because that's what models were showing for several days. As that's changed, he's done a fairly good job of explaining WHAT the pattern is and HOW it has to change to get sustained cold into the east.

There are plenty of times when one call DT out for being a bombastic jackass and totally wrong (and I say that as someone who actually likes the guy). This isn't one of them.

Ji, don't be a dick towards other people just because you're mad that our temperatures are above average. You're acting like it's 70 when the average temperature is 45 not 57.

DT is a master at doing that, anything to inflate his cocky ego more.

It is not just DT I have been following several forecasters for the past few weeks and Joe Bastardi, Joe D'aleo Larry Cosgrove and a couple of others were saying that sometime between Nov 22 and Dec 1 all hell would start to break loose and that Dec and first two weeks of Jan would be very cold and snowy. Now it seems like all of them are pushing back the winter onset including DT. Were there forecasters who were saying DEc would be warm.? Just wondering.

Roger Smith predicted a warm December

In a warm November, it will get cold at some point....it has to....so if you don't get the timing close it isn't much of a call....Unless we have disaster December, we are going to get a 7-10 day stretch of pattern change cold at some point....The verification is getting the timing correct.....I don't know when it will happen...I think analogs support cold rather than warm....But I wouldn't be surprised to see it pushed back til 12/10-15 when the MJO cycles around again....Until then maybe we are ridgy in the means, with periodic 2-3 day transient cold shots.....which probably means no snow, but maybe you get lucky and get a fast moving clipper a day behind the cold front....

I guess I'm at the point I hope we torch till I get back tho since it's too early for snow I doubt I'd miss the cold. Maybe I should convince my dad to take a few day trip to Tahoe.

I'd be kind of stunned if we saw more than a flurry at best here over the next 2 weeks....I will be in the tropics next week until the 27th and I am not worried about missing anything...My biggest concern is it is in the 60s here and I wasted a perfectly good weather week back home while sitting on the beach in the 80s

the alaskan vortex is a stable pattern... i remember when it developed in 2006 and we kept waiting for the pattern change that didn't happen til feb

I think that you are safe, the big AK vortex doesn't look to be going anywhere soon and the AO looks to remain postive. That's pretty bad look. I'm starting to think the pattern change will hold off until after the 1st week of Dec maybe even the second. The mjo looks like it will be in quadrants 4-6 during the 1st two weeks of Dec which generally are on the warm side, especially 4 and 5.

Happy Thanksgiving!

Gobble, gobble.

However, the Euro from 9 days ago wasn't exactly spot on with today's forecast either. So, I'm not getting too worried or excited over 10 day forecasts.

Well, I wanted to post pics from the model, but can't seem to get it to work. Trust me, they aren't a good match.

Question:

Would you (anyone) rather have no systems to track, no chance of snow, or, get to track several systems that manage to narrowly miss us (last year)?

Personally, I'm much more at ease when there is no chance of snow.

For now having nothing to track is fine. Eventually we need something or nothing happens.
