An Excessive Heat Warning is in effect for the entire D.C. area again tomorrow Friday and Saturday. At this late hour the heat index is still above 100. Highs tomorrow will be near the record 103 but with the extreme humidity the heat index will be near 115. That is some dangerous heat.!
On Saturday there is the chance of some afternoon or evening thunderstorms that may bring some brief relief but temperatures will still be near 100. Sunday will "only" be in the mid 90s, but a real decrease in this stifling humidity comes Monday. Stay safe.
