6:30 AM | ***Major snowstorm for NYC region***

Current surface map with low pressure just off the Delmarva coastline

An all-out snowstorm is now underway in the local region and this system will impact regions all along the Northeast US coastline during the next several hours.  Low pressure is intensifying this morning near the Delmarva Peninsula coastline and the atmosphere is very dynamic around here leading to heavy precipitation in the region.  Given the strong dynamics in the atmosphere, there will be small-scale bands of intense precipitation and even some isolated “thundersnow” reports. These bands should produce quite a variation in snowfall rates with some areas getting pounded and others in a relatively dry slot.  The brunt of the storm will take place later this morning and into the early afternoon hours and then the steadiest and heaviest precipitation will push to the northeast as low pressure slides up along the New England coastline.  The snow is of the heavy, wet variety for now and it could weigh down some tree limbs to the point of breakage which could, in turn, lead to some scattered power outages. Temperatures have dropped dramatically since yesterday and will generally stay at or below freezing for the rest of the day and then drop into the teens in the overnight hours. Winds will pick up in intensity as the day progresses and the storm heads to the northeast. Accumulation amounts on the order of 6-12 inches are likely across the NYC metro region.
