D.C. forecast for near 100-degree temps midweek

Context: The heat is associated with a strong area of high pressure aloft, also referred to as a heat dome, that is slowly migrating from region to region, bringing scorching temperatures to areas under its influence.

• The unusually hot air mass for late August already smashed records in the Southern Plains and will focus on the Midwest before shifting Southeast, breaking historic benchmarks along the way.

Zoom in: D.C. may see a thunderstorm on Wednesday. Lows will remain elevated at 72 overnight.

• The heat wave will be short-lived, thankfully. Highs dip to 92 on Thursday and 82 by Friday. The weekend will be in the 80s.
