| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 344pm EDT Sunday Oct 4 2026 .WHAT HAS CHANGED... Have raised the cloud cover forecast given the persistence of low stratus across the area. Otherwise, with tidal flooding looking more likely in Annapolis, have hoisted Coastal Flood Advisories for tonight's high tide. Looking ahead to Tuesday night, the increase in wind around the dome of Canadian high pressure has decreased the threat for frost conditions. .KEY MESSAGES... - 1) Cloudy finish to the weekend, with the potential for frost and freezing conditions west of the Blue Ridge by late Monday. - 2) Dry conditions and warmer temperatures are forecast for Wednesday through Saturday. KEY MESSAGE 1...Cloudy finish to the weekend, with the potential for frost and freezing conditions west of the Blue Ridge by late Monday. A cold air damming (CAD) wedge remains in place across the Mid- Atlantic region. The persistent low-level north to northeasterly winds have maintained a stratus deck with some areas of drizzle. However, any of the more concentrated rainfall remains well to the south around the Virginia Tidewater region. While the mid- level water vapor channel and earlier IAD sounding showed a dry mid-level layer, immense moisture remains trapped in the stable lower atmosphere. For the remainder of the day, expect temperatures to hold steady in the 60s. With some cloud breaks across the Allegheny Front, spotty low 70s are possible across the mountain valleys. Overnight conditions stay cloudy, accompanied by some patchy fog development. Any residual cloud cover should erode as a cold front sweeps through the area early Monday morning. This yields a mostly sunny day with temperatures warming back into the upper 60s to mid 70s, with 60s across the mountains. Northwesterly winds pick up behind the frontal system with afternoon gusts to around 20 to 25 mph. A strong area of Canadian high pressure pushes in from the Midwest on Monday before settling over the local area by the overnight period. This sets the stages for the first widespread frost event, mainly west of the Blue Ridge. The Allegheny ridgetops could even near the freezing mark. For east of the Blue Ridge, forecast lows will be in the 40s. High pressure maintains its influence over the area on Tuesday which brings cool temperatures, lighter winds, and sunny skies. Most can expect highs in the 60s, with mid/upper 50s across mountain locales. Tuesday night also looks chilly, but forecast temperatures have come up a tad given light southerly flow around the departing high pressure center. At this point temperatures would be just mild enough to avoid another frost event. For most, the forecast lows are in the low/mid 40s. KEY MESSAGE 2...Dry conditions and warmer temperatures are forecast for Wednesday through Saturday. High pressure will remain in control locally through much of the upcoming week. Dry conditions are forecast for Wednesday through Saturday, along with warmer temperatures. Highs each day will generally be in the 70s, with lows in the upper 40s to lower 50s. There are signs that the stretch of dry weather will come to an end on Sunday as an area of low pressure tracks northward out of the Gulf toward the Ohio Valley. If this occurs, rain will likely move into the area from the south. However, there's still a lot of variability in model guidance with respect to what will occur with this system, and if/when we'll get rain. Marine North to northeasterly winds are currently gusting around 5 to 10 knots. Any increase in marine winds do not occur until the second half of Monday in response to a cold front. This boundary crosses the waters Monday morning with a shift to mainly west to northwesterly flow. Gusts up to 20 knots are expected for Monday afternoon through much of the overnight hours. Small Craft Advisories are likely going to be needed across portions of the waters. Winds turn lighter into Tuesday with high pressure overhead. Sub-SCA (Small Craft Advisory) level winds are expected for both Wednesday and Thursday. Winds are forecast to be out of the south on Wednesday, and out of the west to northwest on Thursday. Tides / Coastal Flooding Tidal anomalies have risen quite a bit over the last 24 hours with current values around 1 to 1.25 feet. This is bringing some of the more sensitive locations into Action stage, with some tidal flooding possible at Annapolis. The forecast ahead shows anomalies remaining elevated through tonight before post-frontal northwesterlies begin to lower water levels a bit on Monday.
