Mid-Storm Update


Just an update here on things as we wiggle our way through the storm.

Happening Now...

First a quick overview. You can see the radar image.The heaviest precipitation is currently in New England. The rain/snow line shoots up the Hudson Valley and just east of New York City now. All the major NYC sites are reporting snow at this hour. The heaviest snow is in Central New York with Rome, Syracuse, Binghamton and Dansville reporting moderate snow. A radar loops suggests banding occurring from Watertown through Syracuse to Binghamton and into the Poconos. The heaviest snow will concentrate here for the next few hours. There could also be some heavier snow west of Albany as well. Pockets of snow continue to develop around NJ this afternoon, so the best way to phrase the forecast for all of Jersey is "periods of snow, occasionally heavy at times."

Outlook for Tonight

Well, the storm is going to begin to pivot to the west and south tonight. This is going to reorient the areas of heavier snow. I expect heavy snow to move back into NJ and NE PA tonight. Some of this snow will shift south, closer to Philly as well. The heaviest snow will be north of I-195 though. Additionally, a dry slot is going to develop, which could shut some of the snow down, especially east of the Garden State Parkway in Metro NYC. Timing and locating this will be difficult and will likely be a nowcasting situation. However, if you end up under this dry slot, you will see a noticeable decrease in snow amounts.

Warm air will intrude further west into New York tonight as well, so areas east of I-81 are subject to mixing with rain, similar to what you saw the other night.

Snow will accumulate much faster now. All day today, the problem has been sun angle/strength and air temperature. With the loss of the sun and temperatures around freezing, I expect snow to accumulate at a more steady clip. The loss of accumulation today will hamper final totals, but some areas will still do quite well tonight. My thinking is easily 6-10" for the northwest quadrant of NJ and parts of Eastern PA north of I-76.
