Rumor is they're gonna do one more pass.

Regarding EWRC: Interested to see if that large area of subsidence between the core and the feeder bands acts to delay formation and consolidation of that outer band into a secondary eyewall.

One thing I want to comment on here is that the instability of the eye/trochoidal wobbling that was present earlier now no longer is. The eye has warmed, become more stable, and is now definitively moving northeast towards Jamaica as a steady state or strengthening sub-910mb storm. Terrifying stuff unfolding here.

Unfortunately, with atmospheric conditions progressively becoming more favorable with each passing hour, I do not see a scenario where Melissa does not efficiently achieve its MPI. Land interaction or internal structural changes are the only limiting factors until it's picked up by the trough in a few days. I am trying to be optimistic for dry air intrusions or a well timed ERC but that might be wishful thinking. Neither is a given.

Struggling to find a scenario where this isnt a Maria/Mitch level catastrophe for Jamaica and the current tail radar/IR look is not helping that narrative.

DVN was considering headlines last night but ended up deferring. 12z guidance so far showing a bit more eastward extension of accumulating snow than previous guidance cycles have. Think even 1-3" results in a high impact event when coupled with gusts of 55-60mph for several hours. Think WWA is the best fit currently but wouldn't be shocked with a game time blizzard warning if the 12z guidance is a bit closer to reality. Curious to see what they end up doing. Doubly true when you consider that an increase in precip/snow rates will more effectively mix down that monster LLJ.

Live look at this storm, and the season as a whole

Most of it is virga

No idea what to expect between the two waves out here. Range basically from nothing at all to 6"+ depending on which model you look at. No real trend one direction vs the other either

7.3" for the final total in IC

Sounds like dendrites/ratios where a big problem for a lot of people outside the primary axis of snowfall but out here we had good flakes for the majority of the day. I'll take measurements in a bit as snow continues to taper but I'd estimate at least 7-8" in Iowa City. The axis of heavier snowfall was a lot narrower than forecast of which the dry slot in IL is probably partly to blame, but elsewhere I gotta wonder if just poor lift/dry air in the DGZ causing ratios to not pan out the reason for underperforming.

Snow has already begun in IC. Almost 6 hours ahead of schedule

DVN saying 7-10" out here on the point and click. With temps in the teens, winds gusting to 25, and a mid day storm, you really cant draw up a better winter storm

Finally.

Real chance we go into february here with under 5" of seasonal snowfall and BA temp anomalies...

3" on the nose today. More than tripling my season total coming into today in Iowa City

NAM at 84 tends to be north so not putting a ton of stock in that. As others have said, not really gonna put money in this coming north until there's a marked trend of this system doing so.

I’m here to promote high quality discussion with fellow winter weather enthusiasts like me!!!!!

I just want to get pasted with the white stuff

Yea that system tuesday could drop some cement out here if things trend right. NAM/Euro anecdotally have seemed to handle these setups pretty well in the past and they're the ones showing snow this time so I guess we'll see.

I think this is probably the most likely outcome. AA for sure but I’m not convinced that we get crazy anomalies rainers for days tho

DAB+ out there to whiten things up

Comatose this far west so far and probably until at least Christmas

Yea this thing is in free fall again…

Nope still straight as an arrow en route
