Significant Ice storm looming?

Some potentially bad news has developed on some of the weather models
yesterday. Some are trending with colder surface temperatures, meaning
we may have a longer period of frozen precipitation. I still do not
expect a large snow event, I think the ice will be the story. Snow
will break out, transition to sleet or freezing rain and the. Change
to plain rain.

We have a nice done of cold air over us now, and as the low pressure
moves through the Midwest and it pumps warm air into the cold some,
the cold will slowly erode away. Depending in how long it takes to
erode away will determine how long we are sleet or freezing rain.

I think areas in NE PA and NW NJ are in for a very significant to
catastrophic icing event. Areas further south are looking at a
moderate ice threat before changing to all rain.

Not to come with start times, amounts etc
