Just finished taking a walk and there was a very light dusting of snow on top of the sleet/freezing rain.

Receiving more freezing rain than I expected, even in the heavier bursts... Probably about 90% FRZA and 10% IP with temperatures in the upper 20s.

Coating of snow on all surfaces here with visibility dropping below 1 mile

A bit over 2 inches of snow here

Visibility dropping below 0.5mi now, with all surfaces covered. Much better snow growth than our last storm!

We've been under fairly high radar returns all evening in Dauphin County, but having trouble sticking still with warm temperatures still hovering around 32-33°F.

Coating of snow on all surfaces in the Linglestown area, with large dendrites continuing.

Changed over to freezing rain and sleet here now, after about 2.75-3in of snow.

Still light (all) snow here (1.5in), but very poor flake quality (notably the warm nose has pushed back south in the latest CC returns). Watching heavier returns move in from the west and hoping for some better dendrites...

About 1 inch of snow so far near Linglestown, but watching the warm nose push toward the Harrisburg metro.

Thanks! I am back local again and hoping these signs (which are still looking good) for a wintry December pan out too.

We ended up with our first 0.1" closer to Linglestown!

80% sleet in Plainsboro, NJ with these latest radar returns

My family is reporting about 6 inches near Linglestown from last night.

Yep, same here, just light snow in Plainsboro, NJ for the last hour or so.

2.0 inches in Plainsboro, NJ... was hoping for a bit more, but can't complain I guess!

I believe the paper should now be open access - sorry for the issues! https://journals.ametsoc.org/view/journals/clim/36/20/JCLI-D-22-0716.1.xml

While land surface feedbacks are certainly playing a role, we recently reinvestigated this issue and found that ocean-atmosphere interactions can also force this area of cooling: Eischeid, J.K., M.P.

Why has the summertime central U.S. warming hole not disappeared?

Hi! The graphs are mine - the data is not off, and the x-axis is the same for both graphs. Note that this is showing the daily sea ice anomalies (which set a new record in 2020 in terms of the absolute magnitude compared to the 1981-2010 average). This is demonstrated more clearly here. This is not showing the actual extent, which did of course reach a minimum in 2012.

My family just 2 miles west of Linglestown is reporting hail larger the golf balls.

There are numerous studies (older and more recent) that detail the Arctic warming in the early 20th century: i.e., Delworth and Knutson, [2000], Bengtsson et al. [2004], Serreze and Francis, [2006] There is also a fairly nice and concise overview from Skeptical Science. Changes in sea ice are driven by far more than surface temperature. For example, a significant portion of 2016's melt season was forced by bottom melt and increased SST/oceanic heat.

This is just not true. Most of us studying sea ice - atmospheric interactions spend the majority of our time trying to understand and quantify natural climate variability in the context of a long-term record. There is a plethora of peer-reviewed work to showcase the current/recent sea ice anomalies are particularly unusual.

I think this speaks for itself... (from Twitter)

Definitely agree. I think it will be particularly interesting to see the PIOMAS volume/thickness numbers for October. Although now we can get a glimpse at the CryoSat-2 season: http://www.cpom.ucl.ac.uk/csopr/seaice.html
