Weather Summary

High pressure over southern Canada continues to send a wedge of cold air down the eastern side of the Appalachian Mountains. Temperatures will hold steady in the mid to upper 30s through the morning hours. A warm front will move through the area from south to north later this afternoon, to then be followed by a cold front this evening. The frontal passage will result in widespread cloudiness as well as rain showers. Morning temperatures will be above freezing, so there is no concern about frozen precipitation. Clouds and showers will hold the mercury down in the lower to middle 40s during the day. Scattered rain showers will continue into the evening hours with some areas of fog developing. The air behind the front will be on a west wind, so highs on Thursday and Friday will surge well into the 50s to near 60 degrees. By Saturday, 60 degrees is not out of the question, but showers may accompany the mild air. The warm-up will be brief, as another wave of arctic air will be poised to move toward the northeast and Middle Atlantic states by Sunday and Monday with highs only in the 40s. Overnight lows will be in the 20s to lower 30s. A storm system may impact the Middle Atlantic region by Tuesday with a chance of rain and/or snow.
