Call up the Boyz II Men, Enigma, Garth Brooks, and Yanni. The 90s are back! Oh wait, we’re talking heat… Apart from a very few showers in the coming days, the weather story is all about a developing heat wave. Unlike the record dew points and heat indices to start off July, this air mass is drier and a lot less humid. There’s still an intense risk of heat exhaustion but this is not quite as dramatic this time around.
