It was another very warm day and also another day without much humidity. Still, the high of 91 at Reagan National Airport is a record for the date. As we know around here, it’s often more about the humidity than the heat. A dry heat isn’t too common in these parts, so we can try to enjoy it at least a little. Humidity levels are expected to go up on Thursday but will probably hit only the beginning of the somewhat bothersome level in this “warm wave.”

Through tonight: Our air mass remains rather dry, although indications are that we’ll see moisture in the air increase fairly quickly tonight. That should keep readings a bit warmer than last night. Under mostly clear skies, 60s should mostly do it, with a range of about 60-67 likely.

Tomorrow (Thursday): It’s a lot like Wednesday but with more humidity. We might see dew points rise by about 15 degrees from Wednesday’s 40s to near 60 by Thursday afternoon, introducing a touch of mugginess. We’re not talking anything terrible, but it will certainly add to the summerlike feel. We’ve got mostly sunny — but perhaps increasingly hazy — skies, and temperatures rising to the mid-80s to around 90.

Record watch: Reagan National Airport topped out at 91 degrees, breaking the record of 89 from 1930, while Dulles International Airport tied the record of 88 set in 2010.
The bar is a little higher for Thursday. At National we’ll need a temperature of 91 or higher. That was reached in 1965. At Dulles, the mark is 92 from the same year.
