| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 358am EDT Sunday September 28 2025 Synopsis High pressure will build southward from eastern Canada through much of the week. Meanwhile, Tropical Depression Nine near the Bahamas is expected to approach the Southeast coast early this week before stalling then drifting out to sea through mid week. A strong cold front will track across the area by the middle of this week bringing cooler and drier weather. Near Term - Through Tonight Residual light showers and/or drizzle east of I-95 will end shortly as weak area of low pressure off of the DelMarVa coast moves away. Otherwise, widespread low clouds and areas of dense across west of the Blue Ridge will hold on through mid morning before mixing out after 10 AM. Dry rest of the day as high pressure builds to the north. Mostly clear tonight, except for thin high clouds spreading northward from TD Nine. Short Term - Monday Through Tuesday Night Mid-high level clouds will continue to expand northward during the day Monday as TD Nine approaches the southeast coast. The latest model trends continue to show TD Nine moving slower and staying further offshore. Despite this slower and further offshore track, rain is still expected to affect central VA Monday afternoon and Monday evening and may reach areas as far north as I-66. However, the risk of excessive rainfall continues to diminish for areas of central VA and southern MD. By Tuesday morning, drier air will start pushing south again on strengthening northerly winds between TD Nine and building high pressure over Ontario/Quebec region. Clearing will then take place Tuesday night. Low-level thicknesses begin to drop sharply Tue evening signaling a significant change in air mass/frontal passage for the middle portion of the week. Long Term - Wednesday Through Saturday A northern stream trough descending across New England will send a dry front southward during the middle of the week, with strong Canadian high pressure building behind it. This will shunt any clouds and moisture southward and lead to declining temperatures and dew points. Near normal temperatures Wednesday will drop below normal Thursday and Friday. Highs will only reach the 60s. Dew points falling into the 40s will support similar lows for much of the area (remaining in the lower 50s near/east of I-95, while 30s will be possible in the higher elevations. The consensus forecast keeps high pressure through the upcoming weekend, gradually drifting east. Combined with rising heights, this would lead to a warming trend. While unlikely to occur, there are still a few rogue solutions that have what becomes of TD 9 not being affected by the midweek trough, stalling, and then somehow affecting the east coast next weekend. Stay tuned to hurricanes.gov for the latest official forecast from the National Hurricane Center. Marine Winds will begin to diminish after 14Z today. Winds begin to strengthen again Monday through at least the middle of next week. Strong high pressure will build north of the area Wednesday and Thursday while a tropical cyclone remains well to the south. The gradient between these systems may result in Small Craft Advisory conditions in north to northeast winds. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...None.
