https://x.com/TrackerSacker/status/1889003317369696267 I post link this for the mind bending animation, not the source, but look at the wave breaking in the NW Atlantic and watch the West Coast and up to Alaska improvements as the model see the MJO phase 8 arrives. Also, a tendency possible between days 10 and days 15 to 16 for multiple threats arriving out of the TN Valley.

Another day, another more negative AO forecast. Concensus to -5 SD drop. PNA has trended more positive, but according to this calculation site the NAO forecast from the CPC is neutral.

Not very inspiring. After my 3 inches of snow tomorrow night I am thinking about beach season. I don't trust models. Seasonal trend and all.

Once again true winter storm criteria way South. The warning level drought continues. Onto late month.

WSW here but not Philly, sorry @Ralph Wiggum. Interesting depiction of the Northern extent of the watch. Matches the ENE motion of the storm, however wondering about coastal enhancement for some.

If I may, please note that the AO link to the SER will be broken once we get to the end of next week, after that the typical block evolution should increase SECS potential. For example, you can that today on the 264 hour ECM ensemble forecast......... WOOF !

We have a very long ways to go. The block may not be conducive enough for this to be a real threat East of the Fall Line.

Regarding the - AO 4 SD block. This is how we are failing in my area I would imagine. Great post by @bluewave below, which is from the NY forum. Goes to show you even a - 4 SD AO block is no gaurantee of a significnat snowfall. This is the second time in 4 years this is happening with a - 4 SD AO. You can think what you want but somrthing is not working like it should in the snowfall department. The Southeast Ridge would link up only sporadically with weaker to moderate -AO events from the 1950s through the 1990s .The best known stronger event from that era was 1-9-98. It could be related to the stronger Pacific Jet and the record warm Atlantic SSTs. So it’s the frequency and intensity which has been something new during the 2020s. The coming event this week will be the 2nd -4 link up in just a little over 2 years. The south based block in December 2020 allowed BGM to get the 40” jackpot instead of closer to NYC. It lead to the first snowfall shut out for us back in December 2022 with similar past La Niña and -AO levels. Then the March 2023 pattern followed a similar script. Now we are getting mixed precipitation events with this present south based -AO block. The 11-12th event may be one of the few events without mixing issues in NYC. Interior spots that build up a big enough snowpack could become susceptible to flooding if one or more of the coming storms rides too far north. 2nd -4 -AO in only a little over 2 years this week linking up with the Southeast Ridge -4 -AO December 2022 linking up Southeast Ridge 2022 12 18 -4.151 2022 12 19 -3.671 2022 12 20 -3.326 Earlier era linkage during 97-98 super El Niño 1998 1 9 -3.987 1998 1 10 -4.269

Pathetic shit show. WTF.

Would not be surprised to have the GFS trend North next 24 to 48 hours.

I am going to be nutless after this winter.

Your description seems that both threats are not Miller A. And both threats are not widespread. Besides warning level snows here, what is missing are widespread snowfalls that strike points from DC North to Boston. Or, at the least, say lower VA. to say Trenton, NJ.

SE "Tropical "Ridge on roids. More expansive then the block.

If it does hold then its time for that conversation that @psuhoffman mentioned. On to the EPS

I have seen that too in previous years. A negative NAO block linking with the SER/WAR . Hope that is wrong. Ugly . Crazy GFS from just 6 hours ago.

The negative AO trends continue today with the latest updates, now pushing near -4.25 SD. , the PNA has trended more positive within the backdrop of a -NAO during this time. PNA looks great

I prefer it where it is . And, don't be surprised at a severe Nor'easter type event near this date, because the GFS has seen these at long range the past 25 years. Dare I say March 2001, DT's Pamela Anderson bust storm. Was oh so close. It took me a year to recover mentally.

I been frustrated, but I am holding psu to the bigger dog in our neck of the woods eventually . Good luck Rev, maybe we score over the next 30 days with a warning level snowfall.

Another way to fail. All good, I am use to a buffet of failure this winter here. Oh, you are not a horrible person.

Generalized thoughts, lack of cold yielding more wet versus white.

95 % of this will be rain here. We just don't have any really cold air to work with, and lock in place. Very strange. Disclaimer, a miracle could happen, I love to be wrong.

Jesus Christ what the hell do we have to do to lower heights in the East and SE. Freakin nuts ! Do we have to locate the PV over Chicago?

Always seems the least likely failure option(s) becomes reality here most times.

Blocking and favoring our area might still be in the cards, I give it some more time.
