 With all the heat and humidity, some of those storms could be strong with gusty winds, some hail, heavy rain, and lightning, and a very low, but not zero, tornado risk as well. Monday and Tuesday, it's nice with lower temperatures, lower humidity. I'm 7 News' Matt Aldrich for Nevins and the First River Weather Center. Right now, it's 79 degrees in Gaithersburg, 79 in Arlington, and 81 in Lanham.
