thanks so much for joining us at 10:00. i m shawn yancy. and i m laura evans in from brian. tomorrow s temperatures will be at the century mark and the humidity will be making it feel much worse than that. wisdom martin is joining us live and gary mcgrady. gary is live with more on tomorrow s dangerous weather. reporter: speaking of tomorrow s dangerous weather, we re looking at tonight s too because it is still very hot out here. the heat index was still at 100 degrees. the overnight lows are critical in a heat wave. if we don t cool down much, it becomes compounding on your body, and it can really just really cause problems over the course of two or three days, and that s exactly what we re going to have here. let me show you highs today up into the upper 90s everywhere, 98 degrees for national, 98 degrees for bwi and dulles came in at 96 degrees, but that didn t tell the tale. it was the humidity. you know you always hear us talk about this, the heat index was up aro
