Baltimore residents can expect a mix of weather conditions this week, as dry patterns give way to showers and a cool down. The National Weather Service Baltimore MD/Washington DC provides a detailed forecast, noting high pressure tracking south from Ontario that's kept the city dry is on its way out. According to their latest Area Forecast Discussion, a coastal low-pressure system is anticipated to bring beneficial rainfall around midweek, with a strong cold front expected to follow over the weekend.
The current weather pattern remains dry today, with daytime highs in the Baltimore area reaching the upper 70s to low 80s, and a slightly cooler overnight as lows dip into the upper 50s to 60s. Cloud cover is expected to increase as a result of the tightening pressure gradient over the Mid-Atlantic. While central Virginia and southern Maryland may see some showers tonight, most of the region will likely stay dry due to the persistent dry air at the surface.
Moving into the short term, the forecast from the National Weather Service suggests that while the coastal low moving inland will bring showers starting Tuesday morning, heavier showers and strong wind gusts seem unlikely. Rainfall is estimated between a quarter to an inch, especially east of I-95. Residents can expect cooler temperatures with highs staying well below the norm in the upper 60s to lower 70s.
For avid sailors and marine adventurers, the situation on the water demands caution. The tightening pressure gradient may push marine wind gusts to around 25-30 knots in most waters, and there's potential for gale-force winds in specific parts of the Chesapeake Bay. The National Weather Service advises that Small Craft Advisory conditions are likely to continue through Wednesday night. Mariners should prepare for variable winds, with gusts up to around 5 to 10 knots, and potentially up to 15 knots across the southern waters.
Baltimore-area residents should also be vigilant about potential coastal flooding. The onshore winds are set to pick up toward midweek, leading to the possibility of tidal flooding, particularly from early Tuesday through Thursday. The National Weather Service's advisory underlines that minor coastal flooding seems more likely beginning early Tuesday and continuing through Thursday. Individuals in flood-prone zones should monitor water levels and heed local advisories.
