Baltimore starts Friday with temperatures in the mid-70s to low 80s, with a few showers still possible before the morning commute wraps up. Rain chances should diminish toward midday, but the city will stay mostly cloudy before reaching a high near 82, according to National Weather Service. The bigger weather story arrives Saturday, when storms could bring a serious downpour risk.
Saturday Brings The Biggest Flooding Concern
Saturday begins with further chances for showers and thunderstorms, followed by a better chance for showers and thunderstorms between 2 and 5 p.m. High temperatures should reach about 83 degrees, with southeast winds up to 9 mph. Saturday night could remain unsettled, with precipitation potentially persisting, as reported by National Weather Service.
The National Weather Service says heavier rainfall totals could reach 1 to 2 inches in 24 hours in some areas. Forecasters have placed the I-95 urban corridor under a slight risk of excessive rainfall, meaning intense downpours could trigger localized flash flooding. Baltimore residents should be prepared to rethink outdoor plans and never drive through water covering a roadway.
Baltimore’s Stormwater System Adds Local Flood Risk
Baltimore City Department of Public Works records show that the city’s stormwater system includes 1,146 miles of storm drain pipes, 52,438 storm drain inlets, 27,561 manholes and 1,709 outfalls, underscoring the scale of infrastructure involved when heavy rain falls across the city, according to Baltimore City Department of Public Works.
The city’s records also point to a historical reason flooding can vary by location: diverting or covering urban streams through culverts and storm drains altered flood plains and caused downstream flooding, according to Baltimore City Department of Public Works. The cited records provide systemwide infrastructure and historical context rather than naming specific streets or neighborhoods with recurring flooding.
Sunday Turns Hotter Before A Drier Stretch
Sunday could start with rain showers before 2 p.m., followed by breaks of sunshine and a high near 87 degrees; skies should clear Sunday night, with a low around 70, as noted by National Weather Service. Monday then brings ridging and generally drier conditions.
Sunny And Warm Through Midweek
Tuesday is expected to be sunny with a high near 82, while Wednesday remains under persistent ridging. Thursday could bring showers and thunderstorms from a possible midweek cold-front passage. No watches, warnings or advisories are currently posted for Baltimore.
