January 28-29, 2024 Mid-Atl/NE Winter Storm Potential

Looks like Euro could not repeat its Thanos interpretation and bring the several into one cohesive bundle, like it did at 12z. It didn't close off as strongly as the earlier run so it was less than spectacular - 552-549 level did not close off cleanly, so it was a "late boomer". 

With so many vorts within the longwave, we've seen "improvement" yet no real move towards total consolidation -and without that, the column cannot cool sufficiently to overcome to the background warm state conditions we have going into it. 

Back before AGW type conditions, this would have been lead pipe cinch to have been at the very least, a significant winter storm if not major. 

We can't lament that - it is what it is - we can only deal with the reality of being in intractable warmth and it will take either a large storm or a perfectly timed one to pull off major snow. I, for one, can wait until we turn more favorable in Feb when the MJO helps turn things around.

Please don't go there with AGW. Read the book "Unsettled" by Steven E. Koonin. I won't get into the details, but X input does not equal Y output.

12z NAM isn't as cold or qpf laiden as 6z. 🙄

2 mb stronger and SLP located in basically the same place...seems odd.

I'll redact that part of the statement for it seems to have lead you to believe I have some sort of agenda in that regard. Also I misunderstood the acronym to be less accusatory than it is otherwise perceived. In using the word "type" behind the acronym I simply was re-stating the FACT that we're in a historical record super warm back ground state.

Thus, it will take more than our typical scenarios to produce winter -as evidenced by our having most of the requisite elements of what we know to drive winter storms. That being a decent High in Canada. shortwave track South of Mason Dixon over to the benchmark, and a strengthening storm. The end.

Playing this scenario out, I would expect a pretty big push of that blue line south in the next image as the HP is pushing down from the north

Yeah I think it can and will get cold again some time. It's just not cold right now. Very historically warm. It might even take until some things change with the ocean currents but sooner or later it will.

ICON pretty north too. Whether thats good or bad (to have ICON agree), I leave up to the individual to decide. Lol

I personally would take this GFS and run. A nice hold over until February brings the goods.

Ya, positively tilted troughs arent a good thing for us at our latitude in mid-atlantics. Need a tough axis neutral over Mississippi and then to swing negatve.

To God's ears, hope this assessment is correct, we can't predict future with certainty but hoping for the best.

 

Back on topic: I didn't know MJO could have so much influence this Winter with El Nino. It's like the MJO either makes or breaks the chances of winter weather during winter, this storm being an example for many.

Yea but as i said last night, that is a double edged sword. This is such a fine line we are walking. Neutral too early = warm. Warm based system. We are asking a miracle from that miracle high.

if we had entrenched cold, then yea go neutral , then negative early.

I actually understood that. 

Must be my meds

In seriousness though, the GFS continues past the first wave and then allow the "too late" part to drop in an do a mini blow up all on its own. I actually see more snowfall from that than the first.

Keep an eye on that trailingn energy / clipper system Tuesday PM

Just a few things to resolve. 

In Dr Strange Multiverse - the 29th storm goes to set up at 50/50 thus showing what RTC mentioned about cold air neutrality (or some such)

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
A trough moving through the Tennessee River valley will approach the
region Saturday Night into Sunday. An area of low pressure will move
up the Appalachians with a secondary low forming near the VA/NC
border and tracking offshore. This will bring a period of light
to moderate rain for most of the area Saturday night through
Sunday, with the potential for wintry weather in northern NJ and
the Poconos in that timeframe. The 00z deterministic runs
showed a good thump of snowfall but thinking some of the
snowfall totals output is probably overdone given the track of
the low close to the NJ/DE coast and ratios likely worse than
10:1. Thinking the better chance for snow will come Sunday
night/Monday morning on the backside of the system as colder air
works its way in and a more favorable time of day. We will have
to keep an eye on this system as the weekend approaches given
some of the more bullish deterministic guidance. Thinking winds
don`t look to be too much of a factor at least on land. With
some onshore flow, there may be some tidal concerns but too
early to speculate on what the impacts will be.
