Today begins with a mix of clouds and sunshine, but the weather will quickly turn active this afternoon. A First Alert Weather Day is in effect for widespread thunderstorms during the afternoon and evening hours. Many of the storms will be strong to severe with damaging winds being the primary threat, but storms will also contain other hazards like flash flooding and intense lightning.
Alert Day for severe storms after 2 p.m.
Severe storms that form this afternoon and evening will be capable of producing damaging wind gusts, large hail, torrential rainfall, and frequent lightning. There is also the possibility of a few isolated tornadoes, particularly in areas that see sustained sunshine ahead of the front and that are close to Chesapeake Bay. Damaging winds is our greatest concern with the strongest storms packing winds of 65 to 75 mph. Some spots they could even be locally higher, so it's important to seek shelter if storms are approaching your area.
The greatest risk for severe storms is from 2 pm until 8 pm. Please have multiple ways to receive warnings as power outages are possible in areas that receive the strongest storms.
Behind the front, slightly drier and cooler air will filter into the region. Humidity levels will drop, offering temporary relief, and Thursday night temperatures will fall into the mid to upper 60s under clearing skies.
Summer heat and AFRAM weekend
That brief break will be short-lived. By the weekend, a surge of intense heat will build into the region, just in time for major outdoor events like the AFRAM festival in Baltimore. Highs on both Saturday and Sunday will rise into the low to mid-90s, and when combined with elevated humidity levels, heat index values could climb to near 100 degrees by Sunday afternoon.
Festival-goers are urged to take precautions, including wearing light-colored and loose-fitting clothing, seeking shade when possible, and drinking plenty of water. The combination of heat and humidity may pose a health risk, particularly for children, the elderly, and those with underlying health conditions.
Dangerous heat wave next week
The real danger arrives early next week. A powerful upper-level ridge of high pressure will establish itself over the Mid-Atlantic, creating a multi-day stretch of extreme heat. First Alert Weather Days have been issued for Monday, Tuesday, and Wednesday as temperatures soar. Actual high temperatures will flirt with 100 degrees each day, and the heat index could easily exceed that threshold, making it feel even hotter.
Tuesday appears to be the peak of the heat wave, with some spots potentially experiencing heat index values above 105 degrees. These conditions could lead to heat-related illnesses if proper precautions aren't taken. Residents are advised to limit outdoor activities during peak heating hours, check on vulnerable neighbors, and ensure pets have access to water and shade.
Later in the week, the upper-level ridge will begin to weaken, allowing for slightly cooler - though still hot - temperatures in the 90s. As moisture returns to the region, so will the chance for scattered thunderstorms by late next week, offering a potential pattern change as July gets underway.
