Haha I had no idea....I obviously didn't look, but I thought they had some good low level cold, although now that I think about it that was the 4-day Dec rain/ice storm. They avoided some big departures in that one but I guess not in the other rainers.

 

 

BTV put up 5 consecutive days of departures between +20 and +24 in the middle of the month. That is a massive torch.

 

Yet, I still think they will finish the month around -2. :lol:

Yeah 5 straight of 20+ and then another 4 straight of 10+ departures (so 9 straight of 10+). There's only been 2 days this month inside of 5 degrees +/- .

The sharp cutoff was definitely under predicted by both models and by even seasoned mets using the model parameters to try and figure out the reality of the precip shield.

 

In short, nobody predicted there to be a gradient where one went from 1-3" to 8-10" in less than 20 miles. And I don't think it was possible to predict that without the benefit of hindsight.

 

The only thing I think was somewhat predictable (and I mentioned it that morning) was that west/north of I-495 and roughly near and NW of I-84 in CT would have a struggle to reach warning criteria snowfall...which certainly ended up verifying. There are usually very distinct model sigs for very sharp cutoffs and they weren't there in the past storm...that band ended up more intense than forecast and coupleed with the loss of mositure inflow, it created a higher cutoff near the northwest region of that banding than would have been otherwise.

 

Will...I think I posted the GFS UVV and you guys probably had access to the Euro.  I think they aligned and indicated very much that it was a have and have not situation.  Particularly the late GFS nailed it pretty well but still blew on the QPF.  There's no way you can predict it though, but we're mainly talking about putting your hands over your ears and eyes and denying that well W&N the trends were disturbing.

 

I will go back to what I said about it snowing in the teens here.  I never recall you getting buried or even Boston for that matter in those situations.   In fact it's normally much worse with even less snow up that way.

Boston was buried 1/2-3 with temps near 0.

 

And I was near 32.

You don't get blizzards in Boston when I'm at 16 degrees and snowing, 99% of the time.

Well it happens regularly over the decades but not frequently.

Gibbs says hello and asks Ray to please stop the whining

 

 

Worse yet. Pattern showing signs of blocking over the North Pole now, which can aid in cold longevity. Also, heading to a pattern of "storms and rumors of storms" starting Super Bowl weekend into following week. Old man winter has us by the neck and is going to squeeze even tighter
 

 

:weenie:

It is looking more likely that here in Northern VT we will clear January without a big one as I have said. Instead nickle and dime clippers will have to do the trick. Hopefully we don't end up with another round of cutters in Feb.

I am not bullish on a big storm until several days into February at the earliest. We could sneak in a SWFE or something perhaps next weekend...or maybe a scraper for a light to moderate event.

Going through all similar patterns, big storms were hard to find in the next 10 days. There's a ton of smaller events and even moderate events...but big ones are tough. There's a few exceptions so the chance isn't zero for a 12 incher. Early February 1975 was actually an analog that has started to pop up and there was a big interior snowstorm in that pattern.

I am good with small to moderate.  I think eventually we get a biggie, perhaps 2 or 3 the rest of the winter, especially where I am.

18 of 22 days here have been at least 9F away from my avg, 9 each way.  Today should be 10-12F below avg, tomorrow the same or colder.  However, my average temp's slide toward cold ended yesterday (at daily mean of 11.8) and has begun the climb, slow at first, toward the end of snow season.

I think you are underestimating zee sneakiness

 

We were talking about the end of the month into early Feb as allowing the chance for something larger about the same time...but HM doesn't post here. At the time it "looked" like PV retro would allow for something as well as lower heights out west. It was just an overall view. 

 

Now, the pattern overall seems not to favor those events next week. However, if the PV rotates north as another s/w dives south and then SE across the southeast US..then things may get interesting. The euro ensembles show this feature. It's not really painting a big storm on the maps, but it has the euro op deal off the southeast coast next week and then something Friday into the weekend. I'm not hanging my hats onto this, but IMO this looked interesting to me.

I don't know...the more I look at the euro ensembles..the more interesting it seems. Maybe noting happens..but I thought it was interesting. If not Wednesday or Thursday...then maybe Friday or Saturday?
