The week ahead: Fewer storms, but more heat

Jared Smith / June 15, 2025 at 11:37 PM

The good news for this week’s weather is that we’ll see a bit more of a lid put on the atmosphere as we get into midweek, which should help to decrease the coverage of — but not eliminate completely — afternoon showers and thunderstorms. The tradeoff, though, is that it’s going to get hotter, with heat indices creeping toward 105° for the first time this year.
