| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 414am EDT Wednesday September 9 2026 .WHAT HAS CHANGED... No changes to the forecast. .KEY MESSAGES... - 1) Dry and warmer today. - 2) Showers and a few thunderstorms late tonight through Thursday night. - 3) Daily shower and thunderstorm chances continue this weekend and into early next week. KEY MESSAGE 1...Dry and warmer today. High pressure over the Mid- Atlantic today and a southerly flow will allow for temperatures to be about 5 to 7 degrees above average this afternoon. Although we can't rule out a shower in spots between the Appalachian Front and the Shenandoah Valley this afternoon, most areas will remain dry. High temperatures may approach 90. KEY MESSAGE 2...Showers and a few thunderstorms late tonight through Thursday night. As the high breaks down and continues to slide to the east tonight into early Thursday, a cold front will approach the region from the northwest. It will be relatively slow in movement to the south and east. A couple of showers or a rumble of thunder could develop along the front and move into western Maryland overnight tonight shortly after midnight and continue to propagate southeastward throughout the night. Due to the lack of daytime heating, the convection should be mainly due to low level moisture and gradual lift from an approaching cold front. Some upper level energy and a jet streak aloft could add additional lift to showers and a couple of thunderstorms across the region during the day Thursday and into Thursday night. However, a westerly component to the wind in the lower levels could act as a downsloping effect and squash some of this convection in a few places. Highs Thursday could reach the upper 80s to near 90 and dewpoint temperatures could reach the upper 60s to low 70s. The front should be slow to move to the south and east that showers and thunderstorms could linger well into the night Thursday night. Showers and any thunderstorms should become more spotty or isolated Friday morning with the front nearly stalling across the Virginia Piedmont. Highs Friday should be a couple of degrees cooler due to cloud cover, convection and a northerly component to the wind on the north side of the front. KEY MESSAGE 3...Daily shower and thunderstorm chances continue this weekend and into early next week. On Saturday, surface high pressure over New England shifts offshore as a cold front approaches from the northwest. Surface winds shift to southerly, ushering in a more humid airmass. With increased humidity, showers and thunderstorms are possible Saturday and Sunday although are expected to remain below severe criteria. Going into next week, precipitation chances linger but remain low (less than 20%). A low pressure system is currently forecast to track across the Great Lakes with the associated cold fronts impacting the mid-atlantic. Temperatures will be in the 70s and 80s each day with high humidity values yielding heat indices in the low 90s for some. Marine Winds are likely to increase this afternoon into tonight, when advisories will be in effect for all waters. Winds shift to the west and northwest and could remain gusty Thursday as a cold front crosses, possibly bringing a few showers and thunderstorms. Sub-SCA (Small Craft Advisory) level north to northwesterly winds are most likely over the waters on Friday. Winds shift to southerly on Saturday with southerly channeling yielding Small Craft Advisory criteria winds in the afternoon. Winds diminish overnight and remain below SCA (Small Craft Advisory) criteria on Sunday. Tides / Coastal Flooding Tide levels should continue to decrease through today. Sensitive sites could approach minor flood at times, as well, mainly late tonight into early Thursday morning, though west- of- south flow by this time lowers confidence. More notable water level decreases will occur Thursday behind a cold front. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...None.
