 And we stay hot through the weekend with highs in the 90s and heat index likely above 100 degrees. And that's the case for today. The excessive heat warning does continue until 8 p.m. So make sure you're limiting time outside this afternoon. Water, shade, and sunscreen if you have to be outdoors. Plenty of that as heat index will be as high as 110 to even 112. Temperatures now are at 91, Silver Spring, 92 in southeast D.C., and Springfield at 91 degrees.
