Hopefully we can get there. Point and click forecast is for -4 tonight, we’ll see at 11:59 pm tonight . Ice daming in the gutters even with de-icers on from this last event. I’m not the only one. Definitely a colder winter so far.

Lock it up. By the way, how much for Philly?

And still showing cold afterwards. Wondering what stage the MOJO is showing for this next possibly for Sunday?

The 20z HRRR is showing another 6” to come

It’s been fine flakes here for the last few hours. Currently 7/5 10.5” OTG

Oops sorry Expect this transition zone to continue to advect north during the early afternoon before stalling near the Connecticut shore by mid-afternoon.

Same here 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 nea

Currently 9/-10. Shot out a question to DonSoutherland regarding start times tomorrow with the cold dry air in place. It might take a little more time for the snow to reach the surface to what the models are showing. It depends on when the column saturates enough. Don agreed that it is possible. it has happened before, so we’ll see how it unfolds.

Another thought Don is the start time to what the models are showing. The cold dry air in place might hold off for the snow to reach the surface for some time more till the columns saturate especially points north of NYC. Currently 7/-8

Maybe they are considering a mixing issue? Only guessing.

Hopefully it doesn’t push in this far. Unfortunately this will come down to nowcasting time.

I’m thinking it will be for the progression and start times.

Once the information has been inputted, we’ll see these changes and hopefully will lock on to a set forecast. As always, subject to change.

Down to 7 here. Already hit the forecast low. No wind and snowpack is helping with the radiational cooling.

How much for Philly

I would love to have @wdrag to start a thread when and if it’s needed.

I believe that the rule of thumb was there or the Mississippi River to close off.

Surprised to see that. I would have thought it would be suppressed.

4.5” will do it here. Currently 27 and some icing up on spots. 00z runs are coming in a little more bullish for tomorrow’s event up this way. We’ll see.

And now the 12z runs(esp. short term models) have bumped up the snow for tomorrow morning. Maybe 2-3” for us inland folks.
