December Pattern Disco- 2013


Damage In Tolland

Recommended Posts

Appears much more logical, thanks.  I'm guessing the AP records don't extend back thru 1917.  A lot of coop stations came "on line" on 8/1/48.  If Pittsburgh's is one of those, it also misses 1933 abd the most recent (IIRC) Dec sub-zero for NYC, in 1942.

 

NYC was -1 on 12/25/1980.  That is the record at Central Park for Christmas day.

Of course, but it seems sanity sometimes takes a back seat in here. :lol: I love winter as much as anyone. Summer can suck a big one for all

I care....this is what I live for. It just seems lately if your not all cold and all snow all the time..you're an outsider. I also see some horrible reading comprehension. Talking about what models show doesn't equate to a forecast.

one post is all I saw and you act like it is endemic, drama?

Weenies gonna ween. You guys better not talk about a thaw anytime soon.

10-day Canadian temp anomaly has virtually the entire Canadian shield negative, and some areas in south-central approaching extreme values.  I've seen this product for years and that's quite rare to have that much mass on the negative side; and the magnitude notwithstanding.   If this is your source region you are getting very cold.  Question becomes just how zonal the flow is .....

It would be nice to get some true arctic air down here for once, instead of that general nuisance cold. People around here have had it too easy with the winters as far as temperatures go.

Our much heralded and talked about icestorm across the interior cordillera looks like it may come to fruition

Well the back-ground canvas of having -EPO/+NAO would raise that probability some, but that of course is no guarantee.   Not everyone in a tornado watch gets a twister ;)

Yeah this is exactly the pattern that produces ice. Lots of fresh cold lurking and oozing down, meanwhile the lack of blocking in the Atlantic allows these storms to run right up into the cold dome. Over-running and CAD galore.

Our arguably most reliable indicator that has not been used enough lately.

We can just hope this look holds a few more runs.. Would be nice to put down a few inches first ..then let the zr glaze and daze

And not to be self-promoting but I have been bringing this up for a month, that these sort of tele layouts would lend to that.   We've actually been lucky ... well, unlucky depending on one's point of view.  That 32.3 rain event the other day just needed about a 6 hour sooner onset timing and we would have had .3" glazing event.  Just dodged a bullet there.

Is it me or did the CPC NAO forecast undergo huge changes in the last three days?  I think I looked this weekend and now I see a totally different graph.

Edit to add:  I didn't follow the weather with my usual fervor this weekend but I was sure I saw a +1-+2 SD NAO forecast sometime this weekend.
