Free weather forecast for New York, New Jersey, and eastern Pennsylvania.
11:12 PM
The east wind we’ve been expecting is finally kicking in and allowing temperatures to rise quickly over much of southern and central New Jersey. For example, in my own back yard since the wind switch about 30 minutes ago, temperatures have jumped from 31 degrees to 33 degrees with a steady rise indicated. Similar [...]

There are some indications that I’ve seen in the past hour that has me a bit worried about significant ice for central, western, and northern New Jersey and much of eastern Pennsylvania.
At this point, most model guidance had the low level cold air pushed out of central and southern New Jersey and warm air [...]

Very heavy precipitation is quickly moving from southwestern Pennsylvania, West Virginia, Maryland, and Virgina towards eastern Pennsylvania this hour. With temperatures in the 20’s for much of eastern Pennsylvania, significant sleet and freezing rain is expected with accumulations of 0.25″ to 0.50″ of ice possible with this band of freezing rain and sleet.
Philadelphia and [...]

Right now, if you are along the immediate coast, your snow and ice worries are all but over. The strengthening warm air advection off the Atlantic supported by the developing 850 MB low over the Tennessee and Ohio Valley has warmed the majority of the atmosphere above freezing, thus producing all rain for coastal [...]

A very dangerous situation is developing for parts of the forecast area that can lead to some significant icing over parts of the interior by Wednesday morning. These types of forecast can be tricky to forecast because the line between a heavy rain and over 0.25″ of ice is like walking a tight rope [...]
The coastal low is rapidly taking over as the primary low as pressures fall off the Delaware coast. The precipitation shield should be watched for some “back building” over eastern Pennsylvania through late morning and into the early afternoon. However, the majority of the precipitation is over southeastern Pennsylvania, away from Philadelphia.
Over New Jersey and [...]

The thermal gradient is really starting to produce some strong low level forcing (LLF) over the forecast area. The latest observations are in for 7 AM, and there is some striking developments here.
First, as the primary low centered over southern Ontario continues to deepen (now down to 1000 MB), the CAD remains strong [...]

As I begin to update the forecast this evening, I would be foolish in not discussing the cold front that is on the move. Let me say, that the cold air is on a steady march towards the forecast area. The freezing line is currently over northwestern Pennsylvania and is steadily moving south and [...]
Enjoy the warm conditions this morning and early this afternoon, because the rest of the forecast period will feature well below normal temperatures and even the potential for snow, which I will discuss in the next post.
The strong cold front is currently (6:50 AM) moving through western Pennsylvania with a line of light to moderate [...]
Get ready for some rapidly changing weather conditions through Saturday night as a series of disturbances and a very strong cold front moves through the forecast area.
Today through tonight, a disturbance from the southern branch will race ahead of the main trough in a very moist atmospheric environment. The GFS and the NAM are having [...]
