Discussion

Very strong and cold high pressure is anchored across southeastern Canada this morning and the day will begin cold and dry. Meanwhile, low pressure will be developing today along the Carolina coastline and then push northward to southeastern Virginia and then to the Delmarva Peninsula by early tonight. After that, the low will make a bit of a turn and push more to the northeast instead of to the north resulting in a position east of New Jersey by the late night hours. Snow is likely to break out here during the late afternoon hours and given the expected storm track, enough milder air can push in from the ocean to cause a mixing with or a changeover to sleet for a brief time. As the low shifts to the east overnight, any mixed precipitation that falls is likely to change back to all snow as colder air wraps around the system. Total snow accumulations during this storm are likely to end up in the 8-14 inch range across the NYC metro region and there can be a light glaze of ice. One last note, watch for “mesoscale” banding during this storm which could result in heavy bursts of snow and/or sleet and possible “thunder snow” or “thunder sleet”.
