Two atmospheric disturbances within a relatively short distance of one another will impact the area early this week, with the first and more powerful storm grazing the area on Monday. That storm system will strengthen off the East Coast and shift northeastward, bringing periods of heavy snow to Long Island on Monday. The bands of steady snow should graze New York City and the NJ Coast, as the fringe of precipitation sits near the area.

Behind this storm system, precipitation will remain in the forecast — not the typical dry air and clearing that we often see behind Nor’Easters. Instead, another atmospheric disturbance will drive southeastward from the Great Lakes to a position near the Mid Atlantic on Tuesday, and a surface low pressure area will develop off the coast of the Northeast US yet again.

Forecast models have trended farther northwest — and stronger — with a low pressure system, which is forecast to develop on a frontal boundary off the East Coast from late Thursday into Friday. This is the same frontal boundary which crossed the area on Wednesday Night and Thursday morning, brining the area rain and wind.

Models suggest that as the frontal boundary moves offshore, a secondary area of energy in the mid levels of the atmosphere approaches the area. This energy provides enough lift for precipitation, with sufficient moisture, with precipitation redeveloping to the west of the offshore front. After beginning as rain, precipitation is likely to change to snow — with accumulating snow possible during the morning commute on Friday
