Heat Index above 100 will be the norm this week QUINCY (WGEM) - A massive dome of high pressure is parked right over the Midwest, and it’s doing exactly what it’s designed to do: trap heat and keep storms away. Here’s what’s happening: When air sinks under that high-pressure system, it compresses and warms up—kind of like how a bicycle pump gets hot when you use it. That’s why we’re seeing consistent heat day after day, even without extreme weather systems fueling it.

QUINCY (WGEM) - Next week brings what we expect in the Midwest during summer: hot and humid weather. Here’s what’s driving it and what to expect. Heat Index 100°+ Why It Gets Hot and Humid Two atmospheric features are combining to bring heat and humidity. First, an upper-level ridge—a massive dome of air—will build directly overhead Sunday and slide just east into the Ohio River Valley by Monday. This ridge will sit over or near the region for most of the week.

QUINCY (WGEM) - This is a three-part weather story for our area: storms tonight, more storms Friday, then heat building into next week. Beneficial rain Friday with a few heavy downpours Tonight: Showers and Thunderstorms Develop A stationary front has settled into our region, roughly north I-70. As a disturbance in the upper atmosphere approaches, it’s providing lift along that front, triggering numerous to scattered showers and thunderstorms.
