Rowan County is heading into the hottest stretch of the year so far—and it may qualify as our first heatwave of the summer.

What’s Coming

Starting Monday, high temperatures will surge into the mid to upper 90s, with the forecast calling for 96 degrees Monday and 97 degrees Tuesday. By Tuesday and Wednesday, humidity levels will climb again, and the heat index (“feels like” temperature) could reach 100 to 104 degrees in parts of the county—especially south of I-85.

Daily Forecast Highlights:

  • Monday: Sunny and hot – 96°

  • Tuesday: Sunny and hotter – 97°

  • Wednesday: Slight chance of storms – mid 90s, humid

  • Overnight lows: Holding in the mid 70s, adding to the discomfort

What Counts as a Heatwave?

A heatwave is typically defined as three or more consecutive days of unusually hot weather, often based on local averages. For Rowan County, this usually means highs in the mid 90s or above, with added humidity pushing heat indices near or above 100 degrees.

While we may not meet official Heat Advisory criteria (which starts around 105 degrees), the combination of heat and humidity could make for dangerous conditions—especially for outdoor workers, athletes, children, and the elderly.

How to Stay Safe

  • Hydrate often—don’t wait until you’re thirsty

  • Avoid outdoor activity during peak heat (2 to 6 PM)

  • Wear light-colored, breathable clothing

  • Check on elderly neighbors and pets

  • Never leave children or pets in cars—temperatures can climb to deadly levels in minutes

“Heat stress can set in quickly when temperatures reach the mid-90s and humidity rises,” said Steve Monday, Chief Forecaster for Rowan County Weather. “Even if we don’t hit official advisory levels, it’s important to take this upcoming heat seriously. These are the kind of days where planning ahead can truly make a difference.”

Looking Beyond

Forecast models suggest the upper ridge causing this heat may weaken late next week, allowing for a return of afternoon storm chances and some moderation in temperatures. But until then, plan for a dry and scorching start to the week.
