Baltimore is bracing for dreary weather as a coastal low makes its way north along the Mid-Atlantic coast. According to the National Weather Service Baltimore MD/Washington DC, this low-pressure system will combine with upper energy from the west and move out to sea by the middle of the week, with an area of high pressure expected to follow. This shift could mean some stabilization in the weather patterns and likely a welcome respite from the rain and wind.
As of the early morning hours, light showers have already begun to move into the area, with heavier precipitation largely staying to the south and east of Baltimore. Rainfall predictions are modest, amounting to a quarter to half an inch, though up to one inch could be possible east of I-95. A report published by the National Weather Service Baltimore MD/Washington DC depicts rain chances hovering between 40-60 percent for the region, with temperatures held down in the lower to mid 60s due to the overcast skies and intermittent rain.
The winds are also a factor, with increasing velocity through the day expected to peak in the late morning to evening, reaching gusts between 25-40 mph along the immediate Western Shore of the Chesapeake. These conditions lead to Gale Warnings for most waters, with the middle to upper tidal Potomac River under Small Craft Advisories due to slightly lesser conditions. The wind could see a second surge on Monday, particularly east of the Blue Ridge, as the two mid-level cutoffs phase over the region.
Forecasters are also keeping an eye on the potential for coastal flooding, with tide levels steady but expected to rise given the strengthening northeast winds throughout the day. Coastal Flood Watch and Advisory warnings are in place in multiple locations, as minor tidal flooding is anticipated at sensitive spots from Annapolis south and at Alexandria. The "forecast itself is still tricky given the developing coastal low off the Carolina coastline," according to the National Weather Service. Blowout tides might occur following the system's passage, although the latest guidance suggests there may be a rebound of high water levels, potentially leading to minor flooding through midweek.
In broader maritime implications, the Gale Warnings suggest hazardous marine conditions that could persist into the coming week. After the gales eventually subside, Small Craft Advisories are slated to be deployed to cover the gusty winds, which are expected to continue through Tuesday into Tuesday night. It's a rough week ahead for Baltimore with the weather front demanding vigilance across various channels – from terrestrial commuter forecasts to marine navigation bulletins.
