| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 351am EDT Sat April 11 2026 .WHAT HAS CHANGED... Nothing. .KEY MESSAGES... - Turning hotter much of next week with limited chances for rainfall. KEY MESSAGE 1...Turning hotter much of next week with limited chances for rainfall. KEY MESSAGE 1 DESCRIPTION... An upper level ridge will build over the East during the first half of next week leading to a significant warmup with high temperatures approaching or exceeding daily records, particularly Wednesday when more widespready daily hi max and daily hi min are more likely. Expect conditions to remain dry much of next week, except perhaps for an isolated shower or two across the mountains. Marine A northerly surge behind a cdfnt this morning will bring SCA gusts to the waters later today before winds begin to diminish this afternoon. Winds should subside below SCA (Small Craft Advisory) by the end of the day, if not sooner. Winds stay below SCA (Small Craft Advisory) criteria tonight through Sunday, then pick up in strength Sunday night into Monday with SCA (Small Craft Advisory) conditions expected. Another period of SCA (Small Craft Advisory) conditions is likely during the middle and second half of next week. Fire Weather A weak cold front will cross the area later this morning with winds shifting first to NW then N. While it will turn dry with Rh's dropping into the 20s this afternoon, the strongest winds will not overlap with the lowest humidities. Hence, no SPS will be needed. Lighter winds Sunday will preclude any issuance of SPS or RFWs. Hotter temperatures next week combined with gusty SSW or S winds will increase the fire weather risk, particularly Monday and Thursday. SPS's or RFW's may be needed. No rainfall is expected until next weekend. Climate Here are some daily temperature records during the April 14-16, 2026 timeframe: A '+' sign indicates multiple years currently hold that record.
