In case you haven’t noticed, it’s really hot out there. And it is, improbably, about to get hotter.

The National Weather Service has issued heat warnings for the start to next week for Arlington and the D.C. area.

Monday’s high is currently predicted to be 99, while it’s expected to tick up even higher, to at least 100, on Tuesday. That’s before storms potentially arrive Wednesday, which has an expected high of 95, and cool things down.

An earlier Excessive Heat Watch for Tuesday was upgraded to a warning on Monday.
