Bob Chill Posted December 9, 2019 Author Share Posted December 9, 2019 Nice shift on the euro for mid next week. 50/50 blocks hp from escaping as the wave moves through the tn valley. IMO- if the progression happened exactly like the euro shows, it would be mostly or entirely snow/frozen precip. It's a good setup verbatim. ETA: this is a good panel showing what I am saying. This is a bread and butter snow and/or ice event setup 9 Link to comment Share on other sites More sharing options...

It's just incredibly dangerous. I guess it can look really pretty if it really accumulates? Also have to worry about power issues. Also hate those storms where you can the initial thump of snow to rain. Kinda pointless when it literally washes away in a few hours. I just more or less appreciate something other than rain to where it's some form of winter weather. Guess it helps a lot of my power is all ran underground in new development lol but still just a genuine winter enthusiast. Link to comment Share on other sites More sharing options...

There is potential in this look. and I know the guidance is favoring a ridge now but I could see something cut under later next week with this look up top also. After that things go to crap but by then we are in the “not very reliable” range for guidance this year. 4 Link to comment Share on other sites More sharing options...

I'm a little jaded with trends in the mid range though. The follow up rainstorm this weekend looked like a nice cad/snow event in the d8-10 range but it significantly devolved in the wrong direction as leads shortened. Each window is unique. Maybe something pops. After next weekend is looking rough. Link to comment Share on other sites More sharing options...

Maybe something pops. After next weekend is looking rough. Speculation, but the AO should be slightly negative near day 8, ( and possibly declining further from there ) and if so, this may play a role in a better outcome than this weekend. As you mention, originally when the rainstorm this weekend looked like a a nice CAD event I believe the AO was forecasted to be negative, right now that is not the case. A week ago there was posting about a interval during mid-month that would give us a better look up top. Maybe this is going to happen and hence we see the potential in the d8-10 period.

Overall it looks like a window is there and it's a pretty decent signal given we are 8 days out. Plenty of time for it to fall apart lol. 2 Link to comment Share on other sites More sharing options...

That rarely works out. Things aren't disastrous yet with Temps averaging below normal, but the long range is not behaving as models show it days in advance. Short leads will tell the tale.. Keep cold around and get into colder climo and I think we will luck out, but so far, luck has not been on our side. But it’s December 9. How much luck do you expect to be on our side at this point?

Meanwhile, seeing suggestions of higher heights in the NA. Didn't we have a similar situation in 13-14 where people would fret over a crappy pattern in the LR and just around the corner, but the bad looks frequently fell apart once we got closer in time? Last year was the inverse, where the good looks stayed 10-15 days out most of the winter. Not saying this year will play out the same, just interesting..... 3 Link to comment Share on other sites More sharing options...

How does the ao look on the eps? Here's d15 h5. You can make a case for both good or bad down the line. The issue that I'm seeing happens during d10-15. A series of troughs in the epac scour nearly all of NA from cold continental air. Here's the d10-15 mean 850 anomalies.... If this verifies then it will take some work to recover.

Bob Chill Posted December 9, 2019 Author Share Posted December 9, 2019 This shows it better. Here's d8-15 850 temp loop. The beginning of the trouble starts d7 so it's not all that far in the future. Link to comment Share on other sites More sharing options...

Tanks it by 150 this period looks somewhat interesting. the very end it looks to me to be cutting the western trough underneath the blocking and rolling forward would be a decent pattern.

But IF we are to run into PAC trouble, gotta wonder if this could be our last window for awhile (which, again, wouldn't be much different from what we've seen the last several years...the time between Christmas and mid January has become a null-zone, lol) Link to comment Share on other sites More sharing options...

There's no way to know. Could flip on a dime with a pna or epo ridge popping up or it can persist for weeks. I always assume a minimum of 5 days to recover once flow is deflected away from the coast. I won't worry about a way out unless we end up in it first. Link to comment Share on other sites More sharing options...

The tpv cannot be predicted at all from any lead beyond a week or 2. The spv actually can be predicted somewhat further in advance but what the spv does to the troposphere/sensible wx cannot be predicted at all so it doesn't matter if you get the strat right or wrong. 2 Link to comment Share on other sites More sharing options...
frd Posted December 10, 2019 Share Posted December 10, 2019 The "weaklies" look blah-ish to me through the end of January. Looking at 500 along with 2 meter temps they seem to possibly echo the seasonal outlooks from back in October and November. However, what they show is not surprising, and I put very little faith in them. The look also seems washed out, with nothing to hang your hat on.

I need to be a little buzzed to watch my home town team. Ugh ! To clarify, they look a bit on the warm side until the end of January. They also look like the Euro seasonal model runs which depict little high latitude blocking. So, they match the Euro seasonals from Sept and October that forecast little blocking and a not so good pattern for us. I hope that is clearer. 1 Link to comment Share on other sites More sharing options...

Very seasonable start to finish with no major torches or ice boxes. The MA region oscillates equally between slightly above and below normal temps start to finish. If anything, the entire 45 day period looks just like the next 2 weeks. Not great, not a shutout, and should provide chances off and on. One thing I noticed is there are no strong 500mb height anoms parked anywhere. No strong teleconnection signals either. That tells me that inside of the weekly's mean panels are equal distribution of every possible outcome. Lol. 1 Link to comment Share on other sites More sharing options...
