A significant snow/ice storm will commence tomorrow in our area between about 3 pm and 5 pm from west to east.
It will start as snow, then change to sleet and freezing rain by about 8-10 pm from south to north across our area. A dusting to an inch or two of snow is likely before the changeover.
The freezing rain will then change to rain between about midnight and 4 am from south to north across our area with a tenth to a quarter inch of ice possible.
We will then have light rain and drizzle during the day on Wednesday, changing to snow between 8 pm and midnight on Wednesday from northwest to southeast across our area.
The snow will then come to an end between about 2 pm and 6 pm on Thursday from northwest to southeast across our area.
I am now going to increase my potential accumulations from 2-5 inches that I had this morning to 3-6 inches for our entire area (Eastern PA, NJ, Southeastern NY, New York City, Long Island. And I believe I may very well have to increase this again tomorrow as I am starting to think we will be right in the middle of this heavy band that will set up. As you can see in the two American models, the short range model is likely too far northwest with the band and the medium range model is likely too far southeast with the band. Most of the models are right in between, including the typically very reliable European ensemble mean.

Beyond this storm, there will be a chance of snow on Monday as a storm approaching from the Southeastern United States may merge with a storm dropping down from Canada.
We will then have a chance of some snow showers next Wednesday.
The next chance of snow will then be the following Sunday and Monday.
Please join me early in the morning for the latest information.
