2/28/23 storm threat

Strong warm air advection arrives between 03-06z with high pressure moving over extreme NNE. The high is leaving, but the timing is near perfect for overrunning. Temperatures hang around the freezing mark for the I-80 corridor and then crash after 12z into the mid 20's. If the GFS profiles end up correct then those widespread 6"+ amounts are certainly possible. Heaviest snow looks to fall between 6z and 12z, then gradually taper after that. We will all benefit from this mostly falling at night and coming in rather intense.

Probably not important at this range but CMC is terrible for the city.

Yeah there isn't much use looking at the CMC at this range since we have the RGEM. It was great to see the RGEM a little wetter and colder on the 12z run. It gets 3 to 4 inches down to my area and for NYC, which I think is a very good sign for this event. Everything seems on track for an advisory level event.

Surprised anyone is asking this after the long track record of never closing NYC public schools.

In any event, they will never close schools in the city for an advisory level event.

the city no longer has snow days this school season.. in the event a school is closed due to snow remote learning kicks in..

BEST VIEWING TIME for NYC  (snow falling and accumulating) ............      For NYC this looks like a self-cleaning storm and nothing will be left.

                                                                                                          Say 10pm-5am Tuesday night.

Really.     The Freezing Level barely goes below 300' and quickly scoots up to 1,000'+ Tuesday.

Seems a shame that an event like this, that will likely be all melted by storm's end, will end our bid for the least snowiest winter...

Its kind of both a pro and a con that it's happening at night. Night time should definitely help with accumulation at this time of the year but also most of us will miss out on seeing it snow and it'll be mostly gone by tomorrow afternoon (maybe tomorrow morning along the immediate coast).

What's the rationale, why are they not a good tool to look at?

10 to 1 is better? 

Yeah we know ratios are gonna be worse than 10:1 for this event, so the Kuchera maps (which take ratios into account) that are showing less snow make sense.
