Dendrite and ORH hills...but that doesn't mean others can't get in. I say "typical" spots because it's too far out to give specifics.

This winter is on the verge of turning very special.  Early cold, mute warmups, a solid snowstorm in mid December, an increasingly active ss, a -EPO that keeps returning, a great cold source in Canda, a warm up that looks brief and is capped by a snowpack sealing ice storm,...and followed by a cold stormy holiday week.  I think the pattern is basically set for this winter, and given that we have had a -pna and a +ao/nao, it would seem we get a period of some blocking at some point and can score that way.  I'm sure we will have a warm period at some point in January.  I say we cap it off with a huge March noreaster that break the pattern and gives us an early spring.

if we get any blocking this winter goes to another level.

these things sneak up on you...the baseline set by this winter is quite a good one, and the step down has been steady and uninterrupted.  I think the table is set and the food is just going to keep getting better, course after course.  The pattern we are in is pretty stable it seems...I prefer no huge triple phase type storms which could shift the pattern.  But don't you think at some point we get some -NAO?  I have heard the AO looks like it might go neg...that could bring down the nao.  Just give us some mild blockin for a week or 2 with all that cold in Canada, a storm going into the block, a clipper in the middle and a storm going out.  Otherwise, the pattern we are in now is working and will only get better as winter gets deeper.

Nice disco from ALB about evolution end of week/weekend

 

WHATEVER REPRIEVE THERE IS FROM THE PRECIPITATION ON SATURDAY WILL
BE BRIEF AS THE COLD FRONT STALLS JUST TO OUR SOUTH...AND LOW
PRESSURE DEVELOPS ALONG IT OVER THE OHIO VALLEY AND TRACKS UP TO
WESTERN NEW YORK BY SUNDAY. THE RESULT WILL BE MIXED WINTRY
PRECIPITATION MAINLY FROM THE CAPITAL REGION ON SOUTH...AND PURE
SNOW TO THE NORTH. THE LOW WILL COMBINE FORCES WITH AN ALBERTA-TYPE
CLIPPER...PROLONGING THE WINTRY ACTIVITY WELL INTO SUNDAY.

Nice disco from Bismark about the evolution of week/weekend.

 

THE ARCTIC AIR REMAINS IN PLACE THURSDAY THROUGH FRIDAY/FRIDAY
NIGHT. LOW TEMPERATURES BELOW ZERO IN THE NORTH WEDNESDAY
NIGHT...AND OVER ALL OF NORTH DAKOTA THURSDAY NIGHT...AND MOST AREAS
FRIDAY NIGHT. WIND CHILL HEADLINES MAY BE NEEDED THURSDAY NIGHT
THROUGH FRIDAY MORNING. THEN SOME MODERATION OVER THE WEEKEND - BUT
STILL BELOW AVERAGE TEMPERATURES.

That's very encouraging for Rick.

Actually, I pay as much attention to Albany's AFD as BOX's.  This area's pretty much an "oh by the way, the eastern slope....".  I don't think I've EVER seen them reference the VT border in an AFD, but the MA/NH border is referenced continually.

 

Plus, I border two of Albany's zones--the same as I do BOX's.

Looking forward to my Christmas vacation in Massachusetts. I took a look at sea surface temperature anomalies. They're 4+ degrees (celsius) warmer than average off the New Jersey coast, but above the 40 degree latitude line it's 2 degrees below average. Is it abnormal to have these two extremes so close to one another? Do the long range/low resolution models take into account the much warmer sea temperatures?

I'm encouraged by what BOX has for the upcoming weekend.

 

Friday: Mostly cloudy with a chance of rain. Not as cool with highs in the lower 40s. Chance of rain 40 percent.

Friday Night: Mostly cloudy with a chance of rain and freezing rain. Lows in the upper 20s. Chance of precipitation 40 percent.

Saturday: Mostly cloudy with a chance of snow. Highs in the lower 30s. Chance of snow 30 percent.

Saturday Night: Cloudy with a 50 percent chance of snow. Cooler with lows around 20.

Sunday: Mostly cloudy with a 50 percent chance of snow. Highs in the mid 30s.

Not sure if this is OT or not... but this GFS run pretty much doesn't have the big warm up at week's end... In fact, it barely crosses the 540mb thickness contour N of SNE before a smart fropa then lodges a significant polar high into eastern ON/NNE by a week from today.  More like an insubstantial mild-up followed by more cold.

That would be a really nasty ice storm next Sunday/Monday - will have to watch for suppression depression, however.
