HeadInTheClouds Posted December 10, 2022 Share Posted December 10, 2022 Euro brings in colder air as low moves east and gets some snow to the coast eventually. Still long way to go with this. 1 Link to comment Share on other sites More sharing options...
Metasequoia Posted December 10, 2022 Share Posted December 10, 2022 I don't hate where we're sitting 6 days out. There's a lot support for a large storm coming up the east coast with a lot of blocking in place. The models are likely going to flop all over the place for several days to come. Too early to throw in the towel or get too excited. 2 1 Link to comment Share on other sites More sharing options...
bluewave Posted December 10, 2022 Share Posted December 10, 2022 This has to be one of the oddest combinations of teleconnections that we have seen in a while. We usually get a solid Rockies Ridge +PNA spike with so much blocking from Greenland back to Alaska. But we have an unusual east to west trough stuck underneath. There is still a tail of blue behind the cutoff back to the Rockies next weekend. So there is nothing keeping the primary low from cutting to Chicago even several days after a -4 AO block.The secondary low hugs the coast for plenty of rain and wind before ending as some snow. Never seen a 500 mb look like this before 1 1 Link to comment Share on other sites More sharing options...

lee59 Posted December 10, 2022 Share Posted December 10, 2022 I am just glad there is a storm somewhere along or near the coast. Something to track. I really don't buy into the track of north to N. Y. and then a right turn. I think a more general NE track will happen. 1 Link to comment Share on other sites More sharing options...

MANDA Posted December 10, 2022 Share Posted December 10, 2022 Posting for informational purposes only (KMMU) user can draw their own conclusions from this model cycle. CMC offers some robust model members. EURO offers far less. GFS (FWIW) not overly impressive either. Long ways to go and many changes lie ahead. There is going be a 2ndary development but beyond that the details on track / ptypes a long ways from being determined. For my part still leaning on more freezing / frozen ptypes NW of PHL/NYC/BOS corridor. Link to comment Share on other sites More sharing options...

An east-west block from Alaska to Greenland with energy cutting underneath is usually a KU signal even for the coast. But the elongated trough from coast to coast is an oddity. We should have more of a ridge over the Rockies with so much blocking. This is what happened back in December 2000. But the models let the primary run too far north due to the lower heights in the Western US. Classic KU composite from December 2000 Odd trough under the whole length of block with no ridge in Rockies Link to comment Share on other sites More sharing options...

donsutherland1 Posted December 10, 2022 Share Posted December 10, 2022 A system could bring some rain or perhaps wet snow to parts of the region tomorrow into Monday. Areas to the north and west of New York City and Newark could see a coating of snow. Poughkeepsie could see 1"-3" of snow and Port Jervis could pick up 3"-6". As had been indicated with the development of the current EPO-/AO-/PNA- pattern, the potential for snowfall has begun to increase. The 500 mb pattern is highly anomalous for December cases with severe Atlantic blocking, so uncertainty remains higher than normal when it comes to snowfall potential. A sustained colder pattern is currently developing. The latest EPS weeklies continue to suggest that near normal to below normal temperatures could prevail during the December 19-26 period. No severe cold is likely through at least the first three weeks of December. The AO fell reached -4.000 on December 10th. Since 1950, there were 11 cases that saw the AO reach -4.000 or below during December. Mean snowfall for those cases was 9.0" (Median: 9.1"). 64% of such cases saw 6" or more of snowfall in December while 45% of such cases saw 10.0" or more snow. In contrast, during all other December cases, mean December snowfall was 3.5" (Median: 2.5"). 91% of those cases also saw a colder than normal December in the northern Middle Atlantic region. In terms of seasonal snowfall, 64% of those seasons saw 30" or more snowfall in New York City with 45% having 40" or more. Just 18% of such cases had less than 20" seasonal snowfall, both of which had less than 10" for the December-January period. The ENSO Region 1+2 anomaly was -0.5°C and the Region 3.4 anomaly was -1.0°C for the week centered around November 30. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.42°C and the ENSO Region 3.4 anomaly has averaged -0.95°C. La Niña conditions will likely persist through mid-winter. The SOI was +16.71 today. The preliminary Arctic Oscillation (AO) was -4.068 today. During December 1-10, the AO has averaged a preliminary -2.591. That is the lowest December 1-10 average on record. The prior mark was -2.297, which was set in 1985. On December 8 the MJO was in Phase 4 at an amplitude of 1.416 (RMM). The December 7-adjusted amplitude was 1.147 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied 55% probability that New York City will have a colder than normal December (1991-2020 normal). December will likely finish with a mean temperature near 38.8° (0.3° below normal). 1 1 Link to comment Share on other sites More sharing options...

Agreed, that’s gotta be the least chance of verification snow map of all time. I guess it’s seeing confluence causing the lesser totals to the NE. Highly highly unlikely.

Fair, I’m tempering my expectations back down to nothing. In the absence of a better air mass I feel like the storm would need an absolutely textbook track to get snow to me right now. Maybe up by EWR at work I’ll see something. Of course a long way to go, etc. Happy to have something to watch and glad someone is probably getting a significant snowstorm. If I get nothing, I’m feeling good about my chances going forward at least. Link to comment Share on other sites More sharing options...

My location is in the skunked area but if you look at it closely, it's 70%. Not shocking that it's less than inland, but not a suicidal difference. Another way of looking at it is that there is a 28% higher chance of this outcome away from the immediate coast. 1 Link to comment Share on other sites More sharing options...

sussexcountyobs Posted December 11, 2022 Share Posted December 11, 2022 Maybe we should focus right now on the event that will happen in the next 24 hrs? Then move on to a possible storm 6 days from now. 3 minutes ago, snywx said: Where are you located? Link to comment Share on other sites More sharing options...
