In 1920 a strong arctic high settled over the region on Jan 31-Feb 1. Temperatures fell below zero overnight setting records, but both days had highs in the low 20s, probably midnight highs at both ends of the cold spell. Then a coastal moved slowly north and Feb 3-5 all had over 1" of liquid and over 5" of snow each day. I would imagine the mix was similar to the current storm except that it lasted longer. I've seen one old archived photo of horse-drawn carts and old-fashioned cars semi-stuck in a goopy looking mess but I wonder if there are other news reports from that series of events. The storm brought a very cold two weeks to a close and transitioned to a more average sort of pattern in Feb 1920. 

Another historical note, today's NYC record of 10.0" from 1905 was part of a two-day total of 11.0" and that storm was also a coastal low. 

Going back 48 years, residents of the Great Lakes region were told by forecasters to expect a big snowfall the next day, but the models of the time showed a deep low tracking from Alabama to Lake Ontario; nobody was quite prepared for the Cleveland superbomb result (955 mb at Port Huron-Sarnia with low moving due north into Lake Huron). At London ON, winds gusted to 80 mph from the south but it was an arctic wraparound! Temps had dropped from near 40F overnight to 20 F. The storm dropped 15-30" of wind-blown snow over most of Ohio, Michigan and southwest to northeast ON. Toronto had much less snow (about 4" on a SSW wind of 40-60 mph) and saw temperatures drop 15 F deg in two hours from 8 to 10 a.m. on the 26th. I was actually in a weather office plotting maps during this storm, to support air quality forecasts made by the company. My parking spot (in northwest Toronto) was occupied by the housing for the building's air conditioning unit, luckily for me it arrived a few minutes before I did that morning. Jan 26 is a date for huge Great Lakes storms, there was the Chicago blizzard of 1967 and a monster lake effect storm in 1971 that trapped hundreds of people in central Ontario for up to a week. During the 1967 storm, both Toronto and NYC had record highs on Jan 25 but in Ontario the warmth was followed by a sleet and snow storm lasting two days; eventually we went from 60 degrees F to 10 inches of frozen snow on the ground. It then stayed very cold for about six weeks.

Temp up to 17 and DT to 16.  Still mainly sleet here - Monroe, NJ

Mix line seems to be retreating a bit over North Jersey.

Is it snow nw of that line.

Concrete here of 10.5 or so snow / sleet and

14 / 7 about 9 inches on the ground tough with the last 90 minutes of sleet

30s along the coast in NJ  teens and  lower teens just inland

Heavier rates and the snow battles back , lesser and the sleet takes over.  Will hover between the 2 and rack up slower with 3:1 / 5:1 ratios but still another 0.8-1.0  LE to fall.

I’m in Monroe too (Kind of central Monroe, by route 522).  Pretty much all sleet here now.  Can’t complain, even if this is it for the snow. 

Yeah sleet is increasing and now mainly sleet - right down the road from you closer to Jamesburg

Suspect we'll teeter between mix / snow - sleet before becoming mainly sleet here in the next hour.  Vrery good overrunning performance. 

Anod now 50 / 50 Snow/ Sleet.  Close to 8.5  9

Kickass. Keep it coming. Can't believe it's still 11 deg. 

Trying to squeeze as much of the anticipated 1.4 LE as snow - up to 0.46 now.

What's your mix? Some snow, some sleet? Oddly, there's little signal on KDIX base reflectivity (or the other tilts), but KDOX shows it well. 

85/90% snow

more to show extent of precip not the mix line

Just now, Jersey_Snowhole said:

Still all snow here when it changes it will change fast

85 - 90% snow here and +SN

Heavy rates counter acting the sleet progression here in Monroe, CNJ

Mesoscale Discussion 0058
   NWS Storm Prediction Center Norman OK
   1055 AM CST Sun Jan 25 2026

   Areas affected...northern Pennsylvania...southern New
   York...northern New Jersey...Connecticut...Rhode Island...and
   southern Massachusetts.

   Concerning...Heavy snow 

   Valid 251655Z - 252100Z

   SUMMARY...Heavy snowfall is expected through the afternoon with
   rates up to 2 inches per hour.

   DISCUSSION...Widespread heavy snow is already ongoing across
   Pennsylvania and New Jersey this morning. This heavy snow will shift
   northeast through the afternoon. In addition, very heavy rates are
   expected to develop across far southeast New York, Connecticut, and
   Rhode Island. In this region, very strong 700mb frontogenesis is
   forecast between 18Z and 21Z amid strong isentropic ascent. 

   In addition, amid strong warm-air advection, the transition zone
   from snow to sleet is moving rapidly north across eastern
   Pennsylvania and New Jersey (as sampled by KDOX Correlation
   Coefficient). Expect this transition zone to continue to advect
   north during the early afternoon before stalling near the
   Connecticut shore by mid-afternoon.
