On June 9, 2025, a Tornado Watch was declared for parts of Maryland, specifically targeting areas south and west of Baltimore. This alert was issued as meteorological conditions became increasingly unstable with the approach of a warm front. The affected regions included central Maryland, southern Maryland, and the Lower Eastern Shore where the potential for severe weather was deemed to be highest. Forecasters noted that the warm front was expected to advance northward towards the Baltimore metropolitan area, which would result in a significant contrast between the cooler, stable air to the north and the warmer, more unstable air to the south. The dynamics at play indicated a high likelihood of severe thunderstorms forming in the environment south of the warm front. Authorities warned that the storms could not only bring heavy rainfall but also damaging winds, small hail, and isolated tornadoes. The most significant threat was anticipated along a line from Gaithersburg to Annapolis to Easton to Cambridge; thus encompassing areas greatly populated by residents, including the inner suburbs of Washington and Baltimore, plus St. Mary's, Calvert, Charles, Talbot, Dorchester, and Wicomico counties. The general consensus stated that while storms were possible throughout Maryland, the southern and eastern sections were more likely to experience severe impacts. As the day progressed, forecasters advised that any storms interacting with the warm front had the potential to briefly rotate, greatly increasing the chance for tornado formation, especially owing to the enhanced low-level wind shear present at the boundary. However, meteorological forecasts indicated that as day transitioned to night, the severe threat would begin to wane by midnight as storms lost daytime heating and the atmosphere started to stabilize. Later on June 9, 2025, weather predictions indicated a relatively dry start to Monday with a mixture of clouds and sunshine before an anticipated resurgence in severe thunderstorms, chiefly on Monday night. According to the Storm Prediction Center, much of the region fell under a Marginal Risk for severe storms for late that evening. It was also outlined that during the coming week, a cold front would sweep through the area on Tuesday, further impacting weather patterns. Morning showers and storms were expected, particularly east of I-95, although areas behind the front would gradually experience drier and somewhat cooler air. The forecast showed Monday temperatures peaking in the low to mid 80s before the encroaching front ushered in a brief span of quieter weather midweek. High pressure building from the west indicated a turn toward more pleasant weather, with afternoon temperatures nearing 90 degrees with lower humidity expected later. By the end of the week, another cold front was anticipated to approach Maryland, bringing another wave of storms, urging vigilance amidst an ongoing pattern of unstable weather conditions in the region. Forecasts suggested that both Saturday and Father’s Day on Sunday could witness incidents of heavy rain and thunderstorms.
