The city of Baltimore is currently under the influence of high pressure, which is expected to move offshore as early Monday approaches. According to the latest forecast discussion by the National Weather Service Baltimore MD/Washington DC, this transition will give way to a weak cold front crossing the Mid-Atlantic region. Residents can anticipate a mix of mostly sunny skies, along with increasing clouds, especially across the southern parts of the forecast area, with daytime highs lingering in the upper 50s to mid-60s range.
Temperatures dropped into the mid-30s overnight in areas along and east of I-95 due to efficient radiation under clear skies and calm winds—elevating the possibility of patchy frost. Elsewhere, temperatures held around 40 degrees. Light southeast winds are expected throughout the day, but on the nighttime flip side, cloud cover in eastern areas will keep them warmer, while clear western skies will lead to more efficient radiational cooling, as mentioned by the National Weather Service.
Looking ahead, the National Weather Service indicates that Monday might bring precipitation chances back to the I-95 corridor and southern Maryland as the low-pressure system ascends the Carolina coast. The imminent cold front's progression on Monday night may lead to northwest winds on Tuesday, contributing to the potential for a Fire Weather day, given the expected dry air influx. High temperatures will persist in the 50s and 60s with overnight lows in the 30s and 40s for the start of the week.
The long-term forecast—spanning Tuesday through Saturday—calls for a quick succession of weather patterns due to a wavy, yet progressive airflow. A moderately strong cold front is slated to pass late Wednesday with little moisture, likely yielding another dry frontal system. Winds could pick up significantly, with gusts potentially reaching 30-45 mph if the strength and timing of the front coincide with peak diurnal mixing, as per the National Weather Service's forecast. Moreover, next weekend might close out with another strong cold front that could pack more moisture than its predecessors.
In terms of aviation and marine conditions, VFR (Visual Flight Rules) is expected to prevail in the aviation sector through Thursday. Mariners should anticipate southeasterly winds shifting to northwesterly behind the cold front, with wind gusts raising the potential for Small Craft Advisory-level conditions and possibly even gale conditions by Thursday. All pilots and boaters should remain alert to changing weather across the Mid-Atlantic region as the week progresses.
