Febuary 9-11 threat

The bomb from 96-108 hours is the savior here...the PV is not positioned well and this would typically be an inland or coastal hugger but if the pattern goes as shown this should be a benchmark track or slightly west because that bomb which blows up before it does not allow the trough to amplify enough to force the storm to go inland...if we lose that storm at 96-108 however the 2nd event probably at least tracks along the coast.

lol this solution is definitely possible with the pattern in place, a slight variation and we can get a coastal or apps runner.

Snowgoose hit this on the head for the gfs and the euro does the exact opposite.....does not bomb out that 96 hr storm....such allows the end of the week threat to amplify earlier, such we get a inland runner

hr 162 apps runner....rain from dobbs ferry-south

It looks as if we should switch back to snow as the low passes us, at least taking a glance at the MSLP charts and having seen these type of events play out before.

0z ECM, verbatim, is snow-->ice-->rain for the NW suburbs, probably just snow-->rain for the big cities. Could be a nasty situation here, but I'll bet the ECM is too warm as it was for the last coastal.

The Euro and GEM are also diving the energy from 108-120 out west more southerly, the GFS is more progressive with it, given the pattern this winter I have to believe the GFS idea is more correct.

Just wanted to mention on how the euro handles the second storm which would become our 50/50 block. From 120hr to 132, it looks double barreled and weak and strung out well to the NE of Maine. Not saying its wrong but that is going to be huge to watch in future runs..Because everything else looks the same, big time amplification over the ms valley along with a juiced up miller A.

This was a very astute post as I believe the Euro doesn't show the 96 hr storm and thus bring the real even inland.

None of the analogs at 120 hours indicate an inland snowstorm...note that these were all indicating inland storms last event from day 5 onward...the previous system however they were way off until inside 3 days...

Not surprising that none of the analogs for the GFS would show an inland snowstorm considering how progressive it is with the shortwave in the SW US.

ECMWF bias of keeping shortwaves in the SW US for too long has to be considered. The 0z UKMET, GGEM, GFS, GFS ensemble are all substantially faster than the ECMWF while this system is in the SW US and southern Plains, which leads to later phasing.

I never realized how well most places around the region did in that storm...its amazing how that 10 year period was not really as bad as it might seem, its just that every event found a way to screw NYC...the only real overperforming events were 12/28/90 and 2/26/91...other than that it seemed everything else either did not occur or produced less than forecast.

1/22/87 also overperformed. Forecast was for 1-3" with a quick change to rain; ended up with 8-11" and a change to freezing rain in the last few hours of the storm in NYC.

Yup, I know in central Jersey it was not too bad at all actually. Almost every winter in that decade save the last 2 featured over 20" of snow and there was over 50 in the 86-87 winter for Monmouth county. NYC somehow managed no 6" snowfalls, but there were plenty of widespread 6"+ events in areas surrounding.
