| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 400am EDT Thu April 2 2026 .WHAT HAS CHANGED... No significant changes were made to the forecast, though did add a few targeted Small Craft Advisories through this evening. .KEY MESSAGES... - 1) A cold front will waver near or just north of the area Thursday through Saturday resulting in warm conditions. - 2) A strong cold front passing through the region on Sunday could bring widespread rainfall and a drop in temperatures by early next week. KEY MESSAGE 1...A cold front will waver near or just north of the area Thursday through Saturday resulting in warm conditions. A backdoor cold front will drop southward through the forecast area this morning. Low clouds will build in to the north of the front, and some patchy fog or drizzle may also be possible at times. This front will have a huge impact on our forecast high temperatures for today. Central Virginia and the Central Shenandoah Valley may stay to the south of the front and could see temperatures rise into the 80s beneath of mix of sun and clouds. Northeast Maryland will likely have temperatures hold in the low 50s beneath cloudy skies. In between, there will be a very sharp gradient in temperatures in the vicinity of the front. Most solutions favor the DC Metro ending up on the cool side of the front, with low clouds through much, if not all, of the day. The latest temperature guidance was loaded in overnight, which dropped forecast high temperatures tomorrow from the DC Metro north and east another couple degrees. A few showers or storms may form near or to the north of the front during the afternoon, but likely won't pose any threat for severe weather. The aforementioned front will lift north of the area for Friday and Saturday, allowing near record temperatures to advect northward into the area within southerly low-level flow. High temperatures are forecast to reach into the low 80s on Friday, and then mid 80s on Saturday. While a stray afternoon shower or storm can't be ruled out across northwestern portions of the forecast area either day, the vast majority of the time will remain dry. KEY MESSAGE 2...A strong cold front passing through the region on Sunday could bring widespread rainfall and a drop in temperatures by early next week. Cold front moves southward across the area Sun. This looks like a widespread wetting rain (several tenths of an inch). Instability is rather low, but non-zero. Potential for thunderstorms exist, just uncertain on coverage/intensity. Rain moves out by Monday with temps falling back to below average for much of next week. While the growing season has not officially started, some frost/freeze concerns likely exist several nigheights next week. Marine Easterly winds are expected over the waters through tonight before winds turn southerly for Friday and Saturday. SCAs (Small Craft Advisories) may be needed in southerly flow at times on Friday and Saturday, and can't be ruled out in easterly flow this afternoon/evening. SCA (Small Craft Advisory) conditions Sunday as a strong cold front moves through. Widespread rain showers and an isolated thunderstorm are possible, with winds shifting NW'ly by Monday in the wake of the front. SCA (Small Craft Advisory) conditions may still be necessary on Mon, but should gradually decrease as the day progresses. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...None. MD...None. VA...None. WV...None. Marine Small Craft Advisory until 9am EDT this morning for ANZ530>532-538>540.
