 The heat and humidity continue to headline our weather today. Look for a high of 100 degrees at BWI Marshall, but feels like temperatures could soar up near 112 at times. There could be an isolated shower thunderstorm that develops late in the day into the early evening hours. Otherwise, most areas should be dry tonight, partly to mostly cloudy, warm and muggy with a low of 78 degrees by Tuesday afternoon. Another hot one with a high of 101.
