The mercury at National Airport’s thermometer didn’t hit 100 degrees yesterday, but it got damn close—98 degrees and a heat index of 105, prompting a heat advisory that began in the morning and didn’t end until close to midnight.

And you should stock up on deodorant (pretty pretty please), because weather reports indicate that the heat isn’t letting up.

According to meteorologists with NBC 4, this could be with us for 10 days. “The heat wave is expected to last not only through this week, but through the weekend and well into next week as well. Temperatures will climb into the mid and upper 90s, with plenty of humidity,” they say.

This shouldn’t come as too much of a surprise—it is summer in D.C., after all. But summers themselves are changing, according to an analysis flagged by Capital Weather Gang.

CWG summarizes that “punishing hot and humid days will dramatically increase in frequency in the coming decades. In Washington, the number of days in which the heat index is predicted to reach at least 105 degrees triples by 2030 and increases by a factor of five by 2050, relative to 2000.”

The analysis from Climate Central lists D.C. in the top 25 cities with a dew point (summer air moisture) increase since 1970, in the fourteenth slot. Take comfort in the fact that, while you may be sweaty, you’re not imagining things.
