| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 354am EST Wednesday Nov 11 2026 .WHAT HAS CHANGED... Thursday's system has been trending drier since Monday with less precipitation amounts expected. .KEY MESSAGES... - 1) Rain returns Thursday as colder temperatures follow Friday into the weekend, with mountain snow and brisk conditions. - 2) Colder than normal temperatures and dry conditions expected much of next week. KEY MESSAGE 1...Rain returns Thursday as colder temperatures follow Friday into the weekend, with mountain snow and brisk conditions. One more mild day today, although a little cooler than yesterday due to more high clouds before changes begin to occur Thursday. Light rain is expected to overspread the area late tonight/early Thursday as low pressure from the OH Valley passes through the region. Rain or showers may linger into Fri morning across northeast Maryland along an inverted surface trough on the backside of exiting low pressure system. Strong cold air advection begins Thu night with temperatures falling from the mid 50s to the mid 40s at lower elevations and from the upper 40s Thu morning to the upper 20s by Fri morning at the higher elevations. Snow showers will become increasingly likely across the Alleghenies in strengthening cyclonic flow with the best period of snow accumulation from late Thu night through Fri evening. Even in the mountains, snow totals have been trending lower since Monday, but an inch or two of accumulation still seems likely. The snow will start tapering off Saturday as low-level curvature becomes more anticyclonic and cold air advection ceases. KEY MESSAGE 2...Colder than normal temperatures and dry conditions expected much of next week. Longwave troughing will remain over the east coast through early next week. Low level trajectories will gradually become less favorable for upslope snow showers Sunday as low level ridging progresses eastward from the Great Lakes. Overnight lows could be colder in some locations Sunday and Monday nigheights since winds will be lighter. While not an absolute certainty, many areas outside of the urban centers and tidal shoreline will likely see their first freeze by early next week. Note frost/freeze products will cease after November 14 regardless of freezing observations, since it will be two weeks after the average first freeze. There may be a low pressure system that attempts to develop along the southeast coast by Tuesday, but at this time, it appears the strong surface high will keep the local area cool and dry. Marine SCA (Small Craft Advisory) conditions expected late Thu or Thu night and continuing through the weekend in brisk NW flow. Small Craft Advisory conditions will continue in northwest flow through the weekend. Gusts may approach gale force Friday and Saturday, with winds decreasing a bit by Sunday as high pressure gradually approaches. Tides / Coastal Flooding Action Stages are likely Thu night before winds shift to NW. A strong frontal passage will bring a prolonged period of blowout tides Friday and through early next week.
