Baltimore starts Monday, August 31, in the mid-70s with heavy humidity, and the city is headed for a mostly sunny afternoon near 89 degrees. A few showers could pop up before 2 p.m., followed by isolated showers and thunderstorms later in the day, but most of the city should stay dry.
Monday is the opening act for a hotter, more unsettled stretch, with temperatures surging into the 90s and storm chances becoming more persistent through the middle of the week. The updated outlook is a sharper turn from the quieter weekend pattern described in an earlier Hoodline forecast.
Heat Peaks Tuesday Through Thursday
Tuesday is expected to be the hottest day in the near-term forecast, with a high near 96 and heat index values reaching 102. The day should begin sunny, but scattered showers and thunderstorms are possible after 2 p.m., with a 50% chance of precipitation.
Wednesday should reach about 91 degrees with a 30% chance of showers and thunderstorms, while Thursday could climb to 97 with another 40% chance of storms. The National Weather Service Baltimore/Washington office says near-record early-September heat is possible, depending on clouds and storm coverage.
Storm Chances Build As The Week Goes On
Forecasters say the timing and location of storms remain uncertain, but the potential for stronger organized storms increases Wednesday and Thursday as several days of heat and humidity pile up. Any thunderstorms could bring brief heavy rain and gusty winds, so outdoor plans should include a way to get inside quickly.
No watches, warnings or advisories are currently listed for Baltimore. Even so, residents should avoid flooded roads during downpours and head indoors when thunder is heard, particularly during the afternoon and evening storm windows.
Cooler Weather Arrives For The Weekend
Friday stays warm near 89 degrees with another chance of showers and thunderstorms, but temperatures ease to about 85 Saturday and 83 Sunday. Saturday should be mostly sunny with only a slight afternoon storm chance, while Sunday looks sunny and notably calmer.
Overnight lows also fall from the upper 70s early in the week to around 68 Friday night, 66 Saturday night and 65 Sunday night. For Baltimore residents looking for the best outdoor stretch, the weekend currently offers the clearest shot at cooler, drier conditions.
