 WBAL-TV 11. Weather. Impact weather expected today with another very uncomfortably hot and humid afternoon as a heat advisory will go in effect at lunchtime and last until 8 p.m. as high temperatures will top out in the upper 90s, but heat index values easily slipping near 105. It's also going to be tough to escape the heat even this evening as temperatures only drop to the mid-70s. I'm meteorologist Alina Lee on WBAL News Radio 1090 and FM 101.5.
