System Exits Snow Ice Next In Line As Parade of Storms Continues Saturday

The overnight weather system that brought fluffy light snow performed as advertised for the most part leaving a couple of inches here and there, less to the north, more to the south. Across Southern Pennsylvania into Southern New Jersey the snow should be ending from northwest to southeast this morning and that should do it for this storm. However keep your eyes open for the next float in the parade of storms as a low from the Gulf of Mexico will find its way up the coast for later Saturday and Saturday night.

The radar shows the overnight snow and the bands are gradually shrinking and moving to the southeast heading offshore. We should start to see improving weather conditions today though there will be a lot of leftover clouds around and highs just in the upper 20s and lower 30s unless the sun can make an appearance or two this afternoon.

Tonight is cold and clear with lows in the teens. Friday look for sunshine but it will be a cold day with most highs in the 20s to near 30.  Then another cold night follows into Saturday morning with lows in the teens to single digits.

Saturday brings the next storm system but things are going to be a little different this time around. On the lower right of the upper air an upper high is building and this is warming things up aloft down to the mid levels of the atmosphere. On the upper left is the polar vortex and with it the bittern cold air over the Plains and Great Lakes. This is potentially going to create a warm layer between 5000 and 10000 feet Saturday night.

That bitter cold air is bleeding southward in the Northeast and into the Middle Atlantic states. The storm system will be heading northeast to the east of the Appalachians and then off the Delaware Coast. Notice the 32 degree line never makes it inland except for maybe Coastal New Jersey. Otherwise everyone is in the 20s Saturday night.

The result on the NAM model and others is sleet or snow to sleet or some sort of combination. I would hesitate to call this an ice storm because there doesn’t seem to be a large threat of freezing rain with this, at least by what I’m looking at so far.  Also this is not really what I would call a loaded system as fair as moisture is concerned. The warm layer doesn’t extend far enough down into the lower atmosphere. That will make figuring out accumulations a bit tougher as we figure out how much of each type of precipitation. Inland areas and perhaps even the coast for a little while could see some snow in this. However this plays out, it will definitely be slippery in many areas Saturday night into Sunday morning. The system moves through beginning during Saturday afternoon and lasting into early Sunday morning. Temperatures Saturday will be in the 20s to near 30 and hold in the 20s Saturday night. Weather conditions will improve on Sunday with some sunshine returning and highs in the low to mid 30s. Monday look for sun and arriving clouds with highs in the 20s to near 30.

A chance for a more serious ice storm could come Monday night and Tuesday as a stronger storm system lines up to head up the Appalachians and then a secondary develops in North Carolina and moves northeastward. Low level cold air will be ample and will wedge south into the Middle Atlantic States and this could set up a more serious ice storm potential for Monday night and Tuesday so we will monitor the developments here closely. One of the possibilities is that the primary low takes a track up the east side of the Appalachians where cold air is more important. The outcome in this case would be mostly snow with a minimal amount of freezing rain and sleet. That possibility is certainly on the table.
