The air between the two systems will be relatively mild with lows by Monday morning only in the lower 30s, about ten degrees warmer than this morning's lows. An arctic cold front will approach the region from the west on Monday. Temperatures will climb into the 40s to near 50 ahead of the front during Monday afternoon, but then drop into the upper 20s by Tuesday morning. Low pressure will move into the region on Tuesday and produce light snow or snow showers with light accumulations possible, particularly across southern Maryland and southeast Virginia. Temperatures will reach their maximum levels early Tuesday morning, and then fall through the 20s during the day with an increasing north wind. The sky will clear on Tuesday night. Cold high pressure and diminishing winds will enable the mercury to drop into the lower to middle 10s by Wednesday morning. Cold high pressure will dominate the weather pattern from Wednesday through Friday. Highs on Wednesday will struggle to climb into the lower 20s with highs on Thursday in the upper 20s to lower 30s and highs in the lower to middle 30s on Friday.
