NWS predicts an 80% chance of thunderstorms Monday evening and possible rainfall amounts between a quarter and half an inch.

Damaging wind gusts are the primary threat. Storms could also produce lightning, hail and isolated instances of flooding, according to NWS.

Isolated severe thunderstorms and flooding are possible Tuesday afternoon and evening, especially in southern Maryland, NWS said.

Tuesday will be mostly cloudy with a high near 83.

While the Maryland Department of the Environment issued a yellow or moderate Air Quality Index warning for the entire state on Monday, Baltimore City’s health department issued a Code Red Extreme Heat Alert, originally for Thursday through Sunday but extended through Monday.

The city health commissioner may declare a code red during periods of heat that are severe enough to present a substantial threat to the life or health of vulnerable Baltimore residents.

“Excessive heat is the leading weather-related killer in the United States. The effects of extreme heat are exacerbated in urban areas, especially when combined with high humidity and poor air quality,” Baltimore City Health Commissioner Dr. Letitia Dzirasa said in a news release last week. “Extreme heat is particularly dangerous for young children, older adults, and those with chronic medical conditions. I encourage all residents to take the necessary steps to protect themselves as well as their families, neighbors, and pets.”

The heat wave brought a high of 96 on Friday and continued into Sunday with a high of 97 and a heat index value that reached 103. Heat index takes into account temperature and relative humidity and is used as an indication of the apparent temperature as it would be felt by a person outdoors.

Essentially, Brian LaSorsa, a meteorologist for NWS, explained, the more humidity in the air, the longer it takes for people to dry and cool off, which leads them to feeling hotter than the actual temperature.

Before this weekend, the area’s high temperature this year had been 96, on May 31, June 17 and July 1. Baltimore’s highest July temperature on record was 107 degrees in 1936, according to the weather service.

The stifling heat likely won’t last much longer. Temperatures are expected to dip into the 80s this week following Monday’s expected storms.

Cooling centers in Baltimore City will remain open through Monday.
