The National Weather Service at Baltimore/Washington has issued a Freezing Rain Advisory in effect until 9 a.m. Friday for the western shore counties in Maryland. An upper-air disturbance is producing a round of light precipitation this morning. With surface temperatures at or slightly below freezing in many areas, the rain is freezing upon impact. As a result, untreated walkways and side roads may become slick for a few hours. Temperatures will moderate during the day and all precipitation will change to rain with highs approaching 40 degrees, but the rain this afternoon will be fairly light and will taper to scattered showers by evening. A mostly cloudy sky is expected overnight with temperatures remaining above freezing. Meanwhile, a cold front will approach the area from the west on Saturday. Mild air ahead of the front will push northward as the front advances toward the east. This will enable temperatures to climb into the 50s to near 60 degrees on Saturday; however, the trade-off will be a soaking rain in the Middle-Atlantic region. Some locations may receive 1 to 2 inches of rainfall by Saturday evening. On Sunday the front will have moved to our east and winds will shift to the west-northwest. The air behind the cold front will be of Pacific origin, so there will not be a significant change with highs on Sunday and Monday approaching the lower 50s under a mostly sunny sky.
