Thursday, June 4, 2026, started out easy in Baltimore, with sunny skies and morning temperatures in the mid 60s. That mellow vibe will not last long. Highs are expected to reach about 89°F today (Thursday, June 4), climb into the low to mid 90s on Friday, June 5, and peak near 95°F on Saturday, June 6. With only light winds in the forecast, urban neighborhoods and paved areas are likely to soak up and hold the afternoon heat. Late Saturday into Sunday (June 6–7), a round of showers and thunderstorms could brush the area and bring brief relief from the hottest temperatures.
Heat Cranks Up Through Saturday
Each day gets a bit hotter. Look for a high near 89°F on Thursday, around 93°F on Friday, and close to 95°F on Saturday, while overnight lows stay in the mid to upper 60s. West to southwest breezes should remain light, generally 0 to 10 mph, which will let heat build in sun-exposed spots and on pavement. The National Weather Service expects this warming trend to run through the weekend.
Storm Timing And What To Watch
Showers and thunderstorms are possible late Saturday evening into Sunday. The first round is most likely between about 8 p.m. and 11 p.m. on Saturday, June 6, with additional chances for storms Sunday morning and afternoon. Most of the activity should be on the brief side, but any stronger storms could deliver heavy downpours and gusty winds, so it is worth checking updated forecasts before outdoor events. If you have plans outside Sunday afternoon, have a quick shelter option ready to go.
Heat Safety And City Resources
Baltimore’s Code Red extreme heat season runs from May 15 through Sept. 15, and the city opens cooling centers, libraries and recreation centers during heat events to offer air conditioning, water and restrooms, according to Baltimore City. Basic precautions still matter: keep strenuous outdoor work for the morning or evening, drink plenty of water, check on older neighbors, and never leave people or pets in parked cars. Anyone planning long or intense outdoor activity this weekend should build in shaded breaks and keep an eye on the sky for incoming storms.
Plan Your Weekend
If you can, shift heavy exercise or labor to early hours and line up a backup plan in case Sunday storms pop. Parks, waterfront spots and outdoor festivals could see scattered showers.
