Update: Heat advisory for D.C., close-in suburbs

* Trending a little cooler, rain chance Sat. a.m.: Full Forecast | NatCast *

As David discussed in his full forecast, though air temperatures will be slightly cooler today, the humidity will be worse. The net effect is that it's not going to feel much different today than the last several. As such, the National Weather Service has issued a Heat Advisory for the District and Va. suburbs inside the beltway (see map) and Baltimore from noon to 9 p.m. tonight.

Excerpt:

HIGH TEMPERATURES ARE FORECAST TO RISE INTO THE MID 90S THIS AFTERNOON. WHILE IT WONT BE QUITE AS HOT AS THE LAST COUPLE DAYS...THE HUMIDITY WILL BE HIGHER. THE COMBINATION OF HEAT AND HUMIDITY WILL PRODUCE HEAT INDEX VALUES BETWEEN 100 AND 105 DEGREES THIS AFTERNOON AND EARLY EVENING.

So continue to keep heat safety in mind this afternoon.
