Winter Wizard

January 2000 is the ultimate example of a positive bust in our area. The storm was predicted to go out to sea but instead continued northward and dumped over a foot of snow across much of the area. As @MillvilleWx alluded to, NWP models have substantially increased in accuracy since then, so such a large-scale bust likely won't happen again. November 1987 I imagine was a similar type of positive bust. November 2018 is also a good recent example: the storm ended up colder than expected, so areas along I-95 and north and west got quite a bit more than forecast. December 2013 is a different case since that was the result of a mesoscale band in an area of strong convergence. - those types of busts can still happen as models have still have difficulty pinpointing the magnitude and location of those bands. Just ask Binghamton, for example. In February 2009, there was an inverted trough that set up near Philly and dropped a surprise 8 inches over the city.

Yup, it's gorgeous out. It's been way too long since central PA has been a jackpot zone for a Nor'easter. If only this could have happened when I was a student...

Some reports of over 40 inches in that area! https://forecast.weather.gov/product.php?site=NWS&product=PNS&issuedby=BGM ...SNOWFALL REPORTS...

Anyone down to go golfing today? Jk I estimate the final total was between 17 and 18 inches just north of State College- unfortunately my ruler is buried underneath somewhere so can't give an exact total. A storm for the books for many, hope you guys enjoyed! Well worth the trek back to Happy Valley.

Well I ended up making the trek back to State College for this one and it did not disappoint. We weren't quite Binghamton, but I estimate we got around 17-18" of powder. Going to be bittersweet heading back home to Maryland, but after missing out on the Blizzard of 2016, I am quite content. Hope y'all that still cashed in enjoyed and hopefully we'll have more chances in the coming weeks.

Last measurement in State College was 14.5” around 12:30. Still moderate snow falling.

Calling it a foot in State College as of 9:30.

Close to 5" as of 5:00 and even heavier rates than before.

2:30 update: +SN, 2.5" on the ground in State College. Visibility under 1/2 mile with the best rates of the day.

2:30 update: +SN, 2.5" on the ground. Best rates of the day so far.

0.8" in State College as of 12:40.

The initial snow band means business, solidly -SN and already have light accumulations on all surfaces.

Snow has commenced in State College. Earlier than expected.

Had to make the trip back to Happy Valley for this storm! Looks like for the first time in a long time, this entire subforum will be the jackpot zone, hope you all enjoy.

I'm not sure if this was ever mentioned in this forum, but this always struck me as a red flag that there would be an adjustment northwest. Goes to show you how subtle changes to features in the atmosphere could have significant implications downstream.

Yup, they haven't had over a foot of snow since February 2010 - always stuck too far northwest for the Nor'easters that crushed I-95. But climo had to win out eventually. You should be in a pretty good spot out in Winchester too. We got 10.1". Solid but pales in comparison to NEPA. November 2018 was better with 11.5".

41/22 in Annapolis. Decided I'm going to head back to State College for this storm - hoping they finally get crushed after being fringed so many times this decade.

GFS is slightly warmer in the mid-levels otherwise there isn’t really a discernible difference from 12z. That being said, won’t do anything to reduce the tension in this thread lol.

Quite a SE shift on the H7 track...this would make just about all of the forum, including those near I-95, very happy.

The PNA is slightly more amplified out west through 60 hours compared to 18z. No significant changes in the east.

This H5 look at hour 102 is absolutely classic. If it can close off slightly sooner and/or farther south, I think just about everyone in this forum will be very happy. The deformation zone would be pretty sweet verbatim. I think it’s pretty clear the 18z GFS that caused weenie suicides was just a blip; the GEFS suite being east was a red flag. What’s encouraging is seeing the vort pass through sooner, which prevented higher heights from building in the Atlantic. This is key for allowing the system to take an offshore track rather than move too close to the coast, as well as not completely torching the mid-layers. Hopefully the Euro and it’s ensembles can follow suit.

Lots of west leaning members here, tread carefully.

Not sure if I’m allowed to post, but the EPS is clustered farther west than the operational.

Thanks for checking on that, seems to be in line with my hypothesis. The closer the timing between the two systems, the more of a relationship there will be.

If there is any relation, I would maybe think a weaker, flatter system Monday would allow for a stronger Atlantic ridge to build ahead of wave 2. Would need to take a closer look and see if there's an impact.
