As Baltimore residents brace for a varied weather week, the National Weather Service in Baltimore, MD/Washington, DC has issued its latest forecast. NWS reports a cold front will sweep across the area early Tuesday, followed by weak high pressure mid-week and another series of fronts toward the weekend.

The imminent weather conditions suggest isolated thunderstorm development later this evening, particularly in eastern West Virginia and western Maryland, in the 23Z-03Z time frame. While severe weather isn't highly anticipated, Tuesday may still usher in isolated to scattered thunderstorms, mainly south of the Capital Beltway. These conditions could affect mariners, as winds are expected to increase across the southernmost waters late this evening into Tuesday morning, potentially necessitating a Small Craft Advisory for turbulent waters.

Traveling mid-week may prove easier for locals, with the National Weather Service forecasting VFR conditions are expected Thursday and Friday under high pressure. The reprieve from stormy skies offers a brief respite before the region girds itself for another round of potentially disruptive weather. A Coastal Flood Advisory had been in effect for Anne Arundel County, having expired early this morning, but it's a stark reminder of the week's tempestuous start.

As the weekend approaches, forecasters warn of daily chances of showers and thunderstorms due to a stalled out front, with the National Weather Service advising a sustained presence of the subtropical ridge and zonal flow aloft. Although the risk of severe weather is currently minimal, concerns about the potential for flooding due to consecutive storm rounds loom over the forecast. Despite this, daytime temperatures are expected to retreat as the hotter airmass is pushed southward.

Residents and travelers in the region should stay tuned to NWS updates for the latest on potential advisories and weather changes. With a weather pattern as changeable as the one cast over Baltimore, it's best to prepare for sun, storm, and the unpredictability of an East Coast summer.
