 WBAL-TV 11. Weather. It's all about the heat and humidity as we kick off a new week. Temperatures will start out in the 70s, but quickly warm close to the triple digits for actual air temperature. But the humidity will make it feel even worse. Feels like temperatures could be well above 110 degrees for several hours today, as an excessive heat warning remains in effect until about 8 p.m. Tonight, partly to mostly cloudy, still warm and muggy with a low of 78. Gets even hotter on Tuesday with a partly to mostly cloudy sky and a high of 101.
