Maryland weather: 'Code red' heat advisory in effect, with rain and storms likely for Independence Day

A “Code Red” heat advisory is in effect in Baltimore from Wednesday through Saturday, and it could also be a stormy stretch — including on the Fourth of July.

Temperatures are forecast to peak around 90 degrees throughout that stretch. But steadily increasing humidity throughout the week is forecast to make it feel as much as 10 degrees hotter. Forecasters say it will feel like 100 degrees outside each afternoon.


For Independence Day on Thursday, the National Weather Service is forecasting an “active” weather pattern as a wave of low pressure meets a hot, moist and unstable air mass over the region. Meteorologists called it “a recipe for plenty of showers and thunderstorms.”

While rain is forecast to be intermittent, “the intervals of showers and t-storms will likely put a damper on outdoor activities and may result in some event cancellations or postponements,” they said.

Baltimore Health Commissioner Dr. Letitia Dzirasa issued the Code Red advisory, warning that the heat could be particularly dangerous for young children, the elderly and people with chronic medical conditions.

By 2 p.m. Thursday, it was 91 degrees at Baltimore-Washington International Thurgood Marshall Airport, with a heat index of 96. At the Inner Harbor, it was 92 and felt like 97.

A “Code Orange” air quality alert was meanwhile in effect Thursday, indicating unhealthy conditions for sensitive groups such as young children, the elderly and people with heart and lung disease.

An Anne Arundel County woman over the age of 65 became the first to die of heat-related illness in Maryland this year, the state Department of Health reported Wednesday.

The woman, who the department declined to identify, died around 1:45 p.m. June 30.

With the Code Red declaration, cooling centers will be opened around Baltimore City — though the centers will be closed for the Fourth of July holiday.


Cooling centers will be open Wednesday and Friday from 8:30 a.m. 4:30 p.m. and Saturday from 11 a.m. to 7 p.m. at:

The temperature is forecast to feel like triple digits around Baltimore through the Fourth of July holiday this week.
