| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 230pm EST Wednesday Nov 12 2025 Synopsis A clipper system will move across the region tonight. Behind it and over the next few days, high pressure will build in from the west. A warm front is expected to move through Saturday before a cold front tracks across the area by Sunday. This brings the next chance of rainfall. A secondary cold front sweeps through on Monday leading to cooler temperatures next week. Near Term - Through Tonight A fast-moving clipper system will move across the area tonight. Winds will be gusty, although not as strong as the past 48 hours. Winds are expected to gust 15 to 20 mph, but a little stronger over the higher terrain in the western mountains. Low temperatures will not be as chilly as last night with lows bottoming out in the upper 20s in the mountains to middle 30s in the areas to the east with a few places near 40 along the Chesapeake Bay. Short Term - Thursday Through Friday Night With high pressure building in from the west and interacting with the departing mid-level clipper system, winds are expected to gust 20 to 25 mph for most with places in the mountains hitting the 35 mph mark much of the day Thursday. High temperatures Thursday will be about the same as this afternoon with highs reaching the 50s for most. Winds are expected to diminish late Thursday into Thursday night as high pressure moves overhead. High pressure will remain in control on Friday. The diminished wind may allow for Thursday night and early Friday morning temperatures to be about 5 to 7 degrees colder than tonight. High temperatures on Friday with some added sunshine and less cold wind gusts may be a couple of degrees milder reaching the middle 50s to lower 60s. Winds will be mainly out of the northwest or west-northwest at 10 to 15 mph. Milder temperatures Friday night with lows in the 30s to near 40 degree. Long Term - Saturday Through Wednesday Cool high pressure over the Northeast finally moves out on Saturday as a warm front sweeps over the Mid Atlantic. Winds will increase Saturday into Saturday night in advance of cold front that is expected to cross our area early Sunday. All of that brings a chance of rain, most pronounced on Sat night. Not out of the question to get a rumble of thunder too. Then, much cooler temperatures for Monday and Tuesday. By Wednesday, confidence falls as the models diverge, but it looks to be either seasonable with a flat ridge/zonal flow over the East, or continued troughing and cooler temperatures. Also with the 12z, the GFS (Global Forecast System) and Euro converging on a short wave moving east across the eastern US Tuesday or Tuesday night. However no clarity on whether it affects our latitude or further south. Marine Persistent gusty west-northwest to northwest winds expected over the waters through this evening, diminishing some overnight, but then returning gusty again through the day Thursday. Small Craft Advisories are in effect through later Thursday afternoon. There appears to be a lull that could happen in parts of the Tidal Potomac overnight, but may only last a couple of hours. Winds will average 20 to 30 knots, while becoming more southwesterly on Thursday with building high pressure from the west. High pressure should become a big influencer with regards to settling or moving overhead on Friday. Therefore, winds will diminish below Small Craft Advisory threshold. SCA (Small Craft Advisory) winds return Saturday night in advance of a cold front. Sunday will be windy after the cold front crosses the waters with at least strong Small Craft Adv winds expected. Monday will likely remain breezy with continuing SCAs. Fire Weather A Special Weather Statement is in effect for a large area between and including the central Shenandoah Valley and I-95 in Virginia. This area includes the extent of I-66 and areas to the south. The statement indicates the elevated fire danger through 5pm this afternoon. Afterwards, this risk recedes. As for Thursday, relative humidity will drop down into the middle 20s to lower 30s again with a gusty wind. We may need to visit this fire weather threat again Thursday. It seems that looking ahead to Friday, wind speeds may not be present to provide a threat again, eventhough it will be dry.
