These posts are helpful! Means a lot and also indicates "the north trend" I think. THANKS. Keep us posted and hopefully others chime in as the storm is happening. Don't forget to report your totals with NWS! Or report the PType with MPing App.

Don't forget to report your PTypes. Look at all the folks reporting them.

Loop past 3hrs, https://mping.ou.edu/display/40.1304/-79.448296/4/

Zoom in and see exactly where it's raining, snowing, icing.

Great look if you want to understand it.


5000' temp loop with metars past 4hrs.


Pittsburgh light snow has changed to rain past hour because that freezing line at 5000' pushed north.


Cold -10C air "Pinks" holding on in CT...for now. It's in the teens (F) above us right now.


Most importantly look at that freezing line as the storm gets closer.... over D.C now. it's coming.

Not much snow yet in the Toronto area, just a couple inches.

Possibly some more overnight, forecasting sunshine by late morning tomorrow,
I think heaviest snowfall will be south of Buffalo/Rochester, then east over to Maine
and New Brunswick.

Interesting changes in the forecast for Northern NJ from my last check yesterday. Following areas are still under a Winter Storm Warning:

Sussex
Western Passaic (really all of northern Passaic which straddles the NY state border)
Western Bergen

Sussex County:



Passaic and Bergen:



Morris and Warren counties are now only under an advisory:





It looks like the ice threat has diminished for many areas except for the northern portions of Passaic and Bergen counties. Splitting hairs here with such small distances. Interesting storm in that sense.

Just looked outside (almost dark), very light snow fall right now.

Lightly snowing here now.

The rain/snow line has just crossed through my location. I will probably be just to the south of the worst but with 35-45MPH I do stand a chance at getting the rare whiteout (at least for southern Kentucky). Some areas of SE Missouri into Southern Illinois really overperformed with this system.

...WINTER STORM WARNING IN EFFECT UNTIL MIDNIGHT CST TONIGHT...

* WHAT...Heavy snow. Storm total accumulations 3 to 7 inches.
Winds gusting as high as 40 mph.

* WHERE...Portions of southeast Missouri, western Kentucky and
southern Illinois.

* WHEN...Until midnight CST tonight.

* ADDITIONAL DETAILS...Plan on extremely hazardous travel
conditions. The strong winds and heavy snow rates will cause
extremely low visibilities. There have already been numerous
accidents reported.

Not too common to see wording like this in Kentucky.

Lol, it was looking like a complete bust in Cumberland........we were downgraded from warning to advisory. Then the snow started, and hasn't stopped.........back up to warning.

Still 34 degrees at ground level, but snow falling fast. My non-spoter estimate from my front yard is 4 inches of heavy packing snow........probably lost some volume due to temps. Forecast still calling for a change over to rain by 10am.

Much worse I hear along the Allegheny front.
