A storm system developed along a cold front on Monday evening and produced a swath of snow from Annapolis over to the lower Maryland Eastern Shore and south into Tidewater in Virginia. The heaviest snow fell in the Norfolk and Virginia Beach areas where 6 to 12 inches was reported. To the north, 1 to 3 inches of snow fell in the Annapolis area with a dusting to the north and west in places like Baltimore and Washington. Temperatures at sunrise this morning had dropped into the 10 to 15 degree range due to fresh snow on the ground and a clearing sky. The mercury this afternoon has rebounded somewhat into the upper 10s to lower 20s. High pressure overhead will ensure another frigid night with lows in the single digits to lower 10s by Wednesday morning; however, the high will begin to move offshore from Thursday through Saturday and a southerly flow of air will break the current cold snap. Readings will still be chilly on Thursday with highs from the upper 20s to lower 30s, but highs by Friday and Saturday may climb into the 40 to 45-degree range. Another cold front is expected to approach the area on Saturday with a few rain showers, but the front will not make much progress as it moves eastward. At the same time, waves of low pressure may move along the front during the period Sunday through Tuesday and provide the region with light, mixed precipitation. A more significant weather event may occur by the middle of next week with a possible coastal low that could produce heavy rain, snow, or mixed precipitation across the area depending on the ultimate track and intensity of the low.
