D.C. could see hottest May weather in at least a decade on Saturday.
The high could reach 96 or 97, about the hottest conditions ever observed so early in the year.
Since the beginning of April, temperatures have tended on the cool side of normal in the D.C. area. But it faces a blast of heat Friday through Sunday, with temperatures set to leap above typical mid-July levels.
The surge of heat will peak Saturday, when highs could reach the mid- or even upper 90s. Records are likely to be set, and Washington could see its hottest weather ever observed so early in the calendar year. It’s probable that this will be the hottest May weather in Washington since at least 2011 or even 1991.
Although humidity levels won’t be oppressively high, it will be muggy enough that it feels several degrees hotter than the actual air temperature, or close to 100.
The heat is coming a bit on the late side. In an average year, Washington would have hit 90 degrees by May 16, but 2022′s first 90-degree date will probably be Friday, May 20.
While this first 90-degree day is a few days delayed, Saturday’s predicted high in the mid-90s is early for such temperatures. Washington’s average first 95-degree day is not until June 18.
