As Baltimore braces for a wave of moisture and storm activity, the National Weather Service Baltimore MD/Washington DC has issued its forecast, urging locals to stay alert. With a cold front pressing in, the region is poised to experience showers and thunderstorms today, according to a statement from the National Weather Service. "A warm and moist airmass will yield plenty of instability," their forecast discussion notes, citing "2000-3000 J/kg of SBCAPE" suggestive of a ripe environment for severe weather activity. The primary concern is damaging wind gusts, especially during downbursts from strong thunderstorms.
With precipitation values (PWATS) exceeding 2 inches, there's an indication of heavy rainfall that could lead to flash flooding, a risk substantiated by the Weather Prediction Center by placing the area in a "Slight Risk" category for excessive rain. On the temperature front, most of Baltimore will see highs in the 80s, climbing into the 90s for some southern locales before dipping to the 60s and 70s overnight. Moving through the week, the stalled cold front could keep showers and potential thunderstorm conditions alive, primarily southeast of the front and east of the Blue Ridge, before another cold front approaches at week's end.
The aviation outlook echoes these concerns. Gusty winds and lightning within the storms could pose flight restrictions, with the southeastern winds blowing at 5 to 10 knots. The National Weather Service forecasts possible showers and thunderstorms for regional airports, warning of impacts primarily at MRB, CHO, IAD, and DCA terminals as the surface front approaches. Pilots and passengers can expect choppy conditions, particularly through Thursday, as another cold front treks towards the area.
Maritime conditions, while less tumultuous than on land, could still bring challenges. Light winds today under high pressure might lull sailors into a false sense of security before storms hit. The cold front could necessitate Special Marine Warnings by the afternoon and into the night. Boaters are advised to be vigilant as the week progresses, with showers and thunderstorms possibly hampering marine travel, especially by Thursday.
In matters of coastal concern, persistent southeast winds have pushed tidal locations into the Action stage, meaning water levels are higher than usual but not yet at the point prompting immediate action. However, the National Weather Service cautions that Annapolis and similar areas might see tides approach or briefly reach Minor flooding stages during peak high tide cycles. Keep abreast of the situation through the National Weather Service and its constantly updated forecasts at NWS Baltimore/Washington, particularly as the weather pattern evolves throughout the week.
