Baltimore is starting today on the sticky side, with early morning temperatures already in the upper 70s and humidity you can practically feel in your lungs. As the day wears today, the city is expected to reach about 95°F, with heat index values as high as 105°F during midday and late afternoon. The most dangerous hours will land in the middle of the day, so it is smart to skip strenuous outdoor activity and get into air conditioning if you start to feel lightheaded. Late-day storms could also tangle up evening commutes, with brief but heavy downpours possible tonight.
Heat Advisory And Air Quality
The National Weather Service has a Heat Advisory posted from 10 a.m. to 8 p.m. on Sunday, July 5, 2026, for the I-95 corridor that includes Baltimore, warning of heat index readings in the 100 to 105°F range. On top of that, an Air Quality Alert (Code Orange) is in effect for the Baltimore metro and Annapolis area, a heads-up that people with asthma, heart disease, or other lung conditions should dial back outdoor exertion. For full forecast details and the latest updates, see NWS Baltimore/Washington.
Storms Tonight And Local Impacts
Showers and thunderstorms are possible after 2 p.m. and become more likely tonight, with stretches of steady rain and pockets of heavier downpours. New rainfall totals tonight could reach between a half and three-quarters of an inch in some neighborhoods. Multiple rounds of storms into Monday could bring strong wind gusts, localized flash flooding, and brief power outages, so avoid driving through flooded streets and keep a phone charger within reach. If you have outdoor plans this evening, it is wise to line up an indoor backup and keep an eye on local alerts.
Cooling Options And Safety
Baltimore residents who need a break from the heat can turn to municipal and state listings of cooling centers and contact numbers, with community centers and libraries often opening their doors during Code Red or Code Orange events. Check the statewide list for locations and hours before heading out, since availability can shift as conditions change during a heat wave. For contact information and the full list, see Maryland Health.
Tomorrow And The Week Ahead
Monday, July 6, 2026, looks a bit less intense but still unsettled, with highs near 88°F and more scattered storms possible in the afternoon and evening. By midweek, the pattern should turn more seasonable, with highs in the 80s and lower humidity, although an isolated afternoon shower cannot be ruled out. If you have travel or outdoor plans later in the week, keep checking official updates so you are not caught off guard.
