Heat advisory expires; heat doesn't
The National Weather Service has allowed its heat advisory to expire at 6 p.m. But the temperature at BWI remained at 90 degrees, and the misery index remained high. Here's how Sterling put it:
"THE HEAT ADVISORY HAS BEEN ALLOWED TO EXPIRE AT 6 PM. ALTHOUGH HEAT
INDEX VALUES WERE CLOSE TO 100 DEGREES EARLY THIS EVENING...THESE
VALUES ARE EXPECTED TO FALL BELOW THRESHOLD VALUES AS TEMPERATURES
CONTINUE TO COOL. HOWEVER...HEAT INDICES WILL REMAIN ABOVE 90 THROUGH
THE EVENING. PEOPLE ARE URGED TO DRINK PLENTY OF FLUIDS IF
SPENDING TIME OUTDOORS."
We may get some rain overnight, but the heat will be back tomorrow. Real relief starts Thursday.
And while we simmered today, NASA's Earth-observing AQUA satellite was snapping our picture. Here's how the Eastern U.S. looked from space today. (Click on the upper left-hand image to enlarge it.) Notice the haze we were under, and the thunderstorms brewing to our west.
