Dense Fog Advisory Issued For 2 MD Counties, When Will Rain End?

BALTIMORE, MD — The National Weather Service has issued a dense fog advisory for Baltimore and Harford counties for the possibility of dense fog developing Saturday night, which could cause difficulties if you're driving this evening. In the statement, the weather service says, "Areas of fog will develop through the night as a warm front approaches from the south and passes to the north late. Dense fog is possible, especially along the coast, with the visibility lowering to 1/4 mile or less."

The areas at risk through midnight are: northern and southern Baltimore County, northwest and southeast Harford County, including the cities of Reisterstown, Cockeysville, Baltimore, Jarrettsville, and Aberdeen.

"Anyone out driving later tonight should be ready for rapid fluctuations in visibility, use low beam headlights or fog lamps when encountering fog, and allow extra braking distance in case sudden stops are needed," the Weather Service said.

A Dense Fog Advisory means visibilities will frequently be reduced to less than one quarter mile. If driving, slow down, use your headlights, and leave plenty of distance ahead of you.

The Washington, D.C., area has had at least a quarter of an inch of rain each of the last seven days, the Weather Service says. This is the longest streak on record for the area. The previous longest was five days in 2011, 2009, 1975, 1950, 1942 and 1937.

And will it ever stop raining? Weakening showers are crossing the Appalachians; areas of fog and drizzle are forming as well Saturday night, the NWS says. However, the good news is that the chance for rain and storms on Sunday is around 50 percent, and we're definitely due for a weather break.

There is good news in the forecast finally, Thursday and Friday look great, just in time for Memorial Day weekend.

Here is the updated weather forecast for the rest of the weekend:
