Bitter Cold Saturday Into Sunday
Winter Storm Watch for Sunday Heavy Snow Potential
Winter Storm Watches continue for Sunday for all of Eastern Pennsylvania to Southern New England. The set up for the storm system for the East Coast begins today as an arctic cold front passes offshore and very cold arctic air from a brutally cold air mass moving into the Great Lakes. We will see some sunshine today but a cold north wind develops and temperatures today will not get much above the low and middle 30s. We will pretty much hold barely off the morning lows.
Tonight turns bitterly cold with a gusty wind and clear skies. By morning lows will be in the single digits to lower teens including urban areas. The higher end lows will be in Southern New Jersey and around the warmer urban locations. Saturday starts with sunshine but clouds will arrive as the day wears on. High temperatures on Saturday likely will not get out of the teens!

Saturday night low pressure on an arctic boundary across the Deep South begins to make its move eastward through the Gulf States while a secondary low forms on a coastal front along the coast of the Carolinas. Arctic is being wedged southward by a strong high to the north. Snow begins to advance northward through Virginia and Maryland, reaching Southern New Jersey and Southeastern Pennsylvania around 1am and New York City, Northern New Jersey, the Hudson Valley and Long Island between 4am and 7am.
The new nam loop is above and it shows a colder model run where it is colder for longer especially across Northeastern Pennsylvania to Northern New Jersey and Long Island. Literally it would mean double digit snow amounts if this verifies. Amounts for the Southern half of New Jersey have come up a little from overnight but no where near the amounts generated to the north. The reason for this is a change to sleet (in purple)across Southeast Pennsylvania to Southern New Jersey with rain in coastal New Jersey to about Monmouth County. Watching the loop you can see how the northern extent of the sleet gets stuck for several hours or more and that is sign that cold air will be more important.
Above we have the National Weather Service forecast amounts and I think the numbers in Southern New Jersey & Southeastern Pennsylvania should be cut back by 20 to 30% at least, To the north of Interstate 195 in New Jersey and those numbers could be a little high and will hinge on how long areas stay all snow. The Hudson Valley and Connecticut see all snow with maybe a little sleet in the mix toward the end as well as long Coastal Connecticut. The main time all this happens is basically between 7am and midnight when this should wind down. My early call snow forecast is available on my subscription platform on Patreon.
A snapshot of temperatures Sunday evening shows that most areas just inland of the coast will be below freezing throughout the event. At 7pm these numbers are probably close to the highs of the day and will start to drop. Sleet and freezing issues in Southeast Pennsylvania could create very hazardous conditions coming on top of a heavy snowfall. Much of what falls in the evening that reaches close to or over New York City should be in the form of sleet which is not as bad as freezing rain. All of this should come to an end overnight and weather conditions will improve Monday.
Tonight we have a special Joe & Joe Weather Show Podcast (LIVE 7:35PM). We will be covering the storm for all areas across the Northeast, Mid Atlantic, Ohio Valley, & Deep South. Special guests include Meteorologists Dave Tolleris, Bill Goodman, & Alan Kasper. We will also have additional live coverage over the weekend.
