Tonight will continue to see clouds around due to the low-level moisture being around, as some fog is possible in the valleys of the Potomac Highlands into the central Shenandoah Valley. A few showers and drizzle are still possible, mainly across northeastern MD and near the Chesapeake Bay.
Heading into Saturday, after the morning clouds and fog, high pressure to the north will continue to build toward the area and help to clear out the clouds. Highs will range from the upper 60s to lower 70s, so it will continue to be cooler than average across the region. Saturday night, clouds should dissipate as drier air finally moves in, and the dry conditions will continue into Sunday, along with more sunshine. More sunshine will allow the thermometer to rise a little higher, compared to Saturday, as highs in the mid-70s to near 80 for most areas.
In the long term, more dry and sunny days are in store for the region, with the next chance for clouds and showers to arrive late in the week. Daytime high temperatures will look to top out in the upper 70s and lower 80s by the middle of the week, as overnight low temperatures will be in the 50s and 60s for most.
