Baltimore is getting hit with a double whammy Thursday, as hazy smoke from Canadian wildfires slides in on top of mid-July heat that already feels like a wet blanket. Afternoon temperatures are expected to push close to 98°F, with heat-index readings making it feel more like about 103°F at peak hours. The Maryland Department of the Environment has issued a Code Orange air-quality alert for the metro area, so people with asthma, heart disease or other lung conditions are being urged to scale back outdoor time. Thunderstorm chances pick up this weekend, with the highest risk centered on Saturday.
Afternoon Heat And Hazy Skies
Through midafternoon, look for mostly sunny skies mixed with areas of smoke, light west winds around 1 to 8 mph, and an actual high temperature near 98°F. By mid to late afternoon, heat-index values are expected to climb to roughly 103°F. According to the National Weather Service, smoke higher up in the atmosphere may limit daytime mixing a bit, which could keep readings just shy of formal heat-advisory levels in some parts of the city. The smoky haze may trim visibility on some roads and could give the sun an orange tint later today.
Air Quality And Health
The Maryland Department of the Environment has placed the Baltimore City metro under a Code Orange air-quality alert, meaning conditions are expected to be "unhealthy for sensitive groups." That includes children, older adults, and anyone with asthma or heart or lung disease. Those groups are advised to avoid long or intense outdoor activity and to keep medications close. Everyone else may want to dial back outdoor workouts, shorten runs or walks, or shift exercise indoors while the smoke hangs around.
Storms On The Horizon
Rain chances take a noticeable jump this weekend. Saturday is currently forecast to bring a high near 90°F with a sizable chance of showers and thunderstorms, and the setup could support a few stronger storms. Any clusters that form may produce gusty winds and localized heavy downpours, with the potential for repeated rounds into Sunday in spots where the front stalls out. If you have outdoor plans lined up for Saturday, it is smart to sketch out an indoor backup and keep an eye on forecast updates, especially into the evening.
Plan Ahead
Try to schedule heavier outdoor chores or workouts for the cooler parts of the day, drink plenty of water, and consider using an N95 or KN95 mask if you are sensitive to smoke and need to be outside. If you rely on public cooling centers or community spaces, confirm hours and availability before heading out and stay alert for any changes if storms move in. We will share updates if air-quality alerts are extended or if severe-weather watches are issued for the region.
