 Science absolutely helps drive public policy, and in a big way. From anti-smoking campaigns to the food pyramid to exercise recommendations and the dangers of mercury and lead paint, science drives public policy. Problem is, public policy is often too slow to implement changes in a timely fashion. For example, we know teenagers need more sleep than others, and have known this for a long time. Yet schools are only now realizing they should be starting the school day later. We also know that feeding children in school improves outcomes. Yet policy makers argue about this....absolutely no disrespect intended here, you are highly regarded for good reason in these parts. 

We still haven’t  solved the scaling up problem. That why I agree we need much more research. Even in countries like Germany where they take the subject seriously, their energy transition has stalled out. This is a much more challenging issue than any of the topics that you mentioned. Those are simple compared to climate change. That’s why it looks like our default position will be business as usual and doing the best we can to adapt.

The last 6 days of December are averaging 46.5degs., or about 12.5degs. AN.

Month to date is  -1.2[37.1].        December should end near  +1.4[38.9].

41* here at 6am.     40* by 8am.

All the models look like horror shows for their durations.    Let's start a contest to see which one has the fewest under 32* days or the most over 50* ones.

Time to admit the SW Event not in our favor.

The first 5-Day period with a BN average T  is centered on Jan. 08, and looks more like the PV sticking its tongue out at us, as the core of it flies by to the north.

The warm weather is not a horror show, I just wish it didn't rain.

Hard to disagree, but in truth rather depressing.

Very bleak for snow lovers like myself. Hopefully the second half of January brings us some heavy snow! Currently humid with a temperature of 39 degrees.

I'm sure something will pop up, just hope it isn't a nearly 3 month wait between snows like last year. Overall in terms of snow last year was close to a stinker IMBY, as was the year before. However, a blockbuster winter is probably not likely. We'll know more in a few weeks.

How much forward Anthony? I've come to suspect any models that keep pushing the cold 6-10 days away. 

The pattern is more of a bad 70s/80s pattern than a 90s/2000s shutout all out torch.  Something may pop at anytime in the next 15 days that produces snow where as we were totally hopeless for large portions of winters the last 20-25 years

Day 11-15 models have been underestimating the influence of the SE ridge and WAR the last few years. Like we saw this week, the ridge verified much stronger than the old long range forecasts. This has created the week 2 favorable looking pattern that keeps getting pushed back.

I hope all of you had a very nice Holiday , I just wanted to recap where we have been , where we are and where we may go.

 

1st Nov 1 - Dec 20 was well BN in the east.

The 1 to 2 week warmup has been one the models have seen for a while now and AN December based on a back end warm up was seen back on Nov 10th.

The question is does the MJO get into 7/8 in Jan , I believe it does. I would be careful using the RIMM plots as they like to chase convection.

We look to be getting into p7/8 by week 2 with the TPV spreading out of the Canadian Prairies into the N/E

How long does that last ? It will depend on how much ridging can force itself into Alaska and attempt to displace the TPV to the east of the Rockies. 

 

I like a BN regime to return some time during the 1st week in Jan. The question is will it hold  or is it in and out after 5 days ? Does the trough just settle down the Rockies once again ? 

That part is up for debate.

Thanks for the breakdown. Always appreciated.

Don't you keep them up thru the first week of Jan?

Nah... I like them up from Thanksgiving Week until now. Same with my tree. Spending tomorrow and Saturday getting everything down and packed away.

I love Christmas and how you're supposed to go through the New Year and Epiphany, but I'm done once the 26th rolls around.

Yeah I really enjoy the holidays...feel a big letdown after new years. Have a happy.

I keep it up to the 1st but that’s it.  Starts so early I’m sick of it by even now
