Baltimore gets one more sunny break Saturday before late-summer heat moves back in. Skies will stay clear to mostly sunny, with a high near 83 and lighter east winds around 6 mph. Rain is not expected, making it an easy day for parks, patios, and outdoor plans.

Clear Saturday Night, Hotter Sunday

Saturday night will be mostly clear, with temperatures dipping to around 68 and only light southeast winds. Sunday brings a sharper turn toward summer, with a high near 89 and more humidity in the air. A slight chance of showers and thunderstorms arrives after 2 p.m., with a 20% chance of precipitation.

90-Degree Heat Builds Next Week

Monday through Thursday will bring highs near 90, 92, 93, and 92, respectively, with partly sunny skies and periodic showers or thunderstorm chances. The best odds generally arrive during the afternoon and evening, though the forecast remains dry much of the time. A National Weather Service discussion says late-summer heat is expected to persist while storm chances increase during the week.

Friday Brings A Small Cooldown

Friday looks somewhat less intense, with mostly sunny skies and a high near 87. There will still be a slight chance of rain showers after 2 p.m., followed by a partly cloudy night with a low around 68. For Baltimore residents, Saturday is the clearest and coolest window before the thermometer settles into a hotter pattern.
