An upper-level low will dig down across the United States on Friday, January 15th, which will bring rain and warmth into the area by Friday evening and into Saturday morning. The rain may become heavy at times as a surface low attempts to form just off of New Jersey. Temperatures will rise into the 40s and possibly lower 50s as the warm sector lifts northward into the Garden State. Tropical moisture will also be advected into the region, increasing the precipitable water values to about an inch, at least according to the Canadian model. The GFS is a bit colder with not as moisture available. The farther away the low develops from the shore, the farther away the axis of heaviest precipitation will be. Once the cold front and surface low-pressure system depart, temperatures will start to fall to near-normal or just above-normal for Saturday afternoon and evening.
