The National Weather Service in Baltimore, MD/Washington DC, has issued an area forecast for Baltimore, outlining a weather scenario involving a backdoor front impacting northeastern Maryland this morning. According to the forecast, the front is part of a larger system hovering over Pennsylvania and New Jersey. While high pressure continues to hold steady offshore near Bermuda, the region should brace for a cold front from the Ohio River Valley by Monday afternoon. The National Weather Service notes that temps will rise well into the 70s to around 80.
In the short term, weather conditions are expected to shift dramatically as the cold front sweeps across. A statement detailed by the National Weather Service indicates that storm activity is likely, with the chance for semi-discrete supercell thunderstorms with an accompanying hail and tornado risk, in addition to a damaging wind risk with any bows/lewps within broader bands of thunderstorms. The forecast warns that Monday's tempestuous weather could easily segue into multiple rounds of storms, potentially offering some needed rainfall.
Colder air will follow the stormy weather, with high pressure briefly asserting its presence on Tuesday into Wednesday. However, this is expected to be short-lived as another system will approach on Thursday and linger heading into the weekend. The mid-week respite will give way to chances for precipitation, especially along and west of the Alleghenies, with the wet pattern continuing through Saturday.
Marine conditions will similarly be choppy ahead of and following the front passage. "Bouts of southerly flow gusting 20-25 kts is expected at times through Monday," the National Weather Service advises. They detail that winds will pivot to the northwest post-front, with a gradual subsiding expected by Tuesday. SE winds on Wednesday will take a turn and become SW on Thursday. The forecast suggests that Small Craft Advisory conditions may persist from noon today until noon EDT Tuesday for multiple zones.
Tidal impacts are also on the radar, with sensitive tidal locations such as Baltimore, Annapolis, and Havre De Grace projected to reach the Action stage due to the intense cold front. The Weather Service explains, "Strong southerly flow will lead to increased tidal anomalies ahead of the frontal passage, with anomalies peaking on Monday."
