 Alrighty, hot and humid as we move through the remainder of the morning and then into the afternoon. Daytime high temperatures today anywhere between 95 and 99 degrees. Heat index values 100 to 110. That's why we have a heat advisory now in effect until 8 o'clock tonight. That is for the D.C. Metro and excessive heat warning along the bay. That's where it's going to be the hottest in terms of those feels like temperatures. Can't rule out a chance for an isolated shower or thunderstorm later this afternoon into the evening.
