Discussion
The biggest snow and ice storm in years is heading to the eastern US. High pressure will continue to build into southeastern Canada today and it will result in a dry and very cold day here in the Mid-Atlantic region as we await a significant mid-week storm system. This next storm will likely begin here with all snow on Wednesday during the early-to-mid afternoon hours. The snow will become heavy at times by day's end and there can then be a mixing with sleet and/or freezing rain. The brunt of the storm will take place tomorrow night when snow or a mix of snow, sleet and/or freezing rain likely changes back to all snow and it'll come down heavy at times with significant total snow accumulations by daybreak Thursday. Current estimates of snow accumulations are as follows (and it may be compacted some with ice): 4-8 inches in the Philly metro region, 6-12 inches in the N/W suburbs. Snow winds down early Thursday and the rest of the day will feature breezy and very cold conditions and snow showers are possible in the PM hours.
