The Dog Days Are About to Bite: Why Rowan County’s Heat Could Get Worse Next Week

The dog days of summer are making their presence known across Rowan County, and the hottest weather of this stretch may still be ahead of us.

Temperatures are already running well into the 90s, but the pattern developing across the Southeast favors continued hot and humid weather through the weekend and into next week. By Monday, temperatures in parts of Rowan County could approach the upper 90s, while humidity could make conditions feel even hotter.

The latest forecast for Salisbury has Monday reaching around 98 degrees, following highs in the middle 90s through much of the weekend. Friday could also bring heat index values around 104 degrees.

A Strong Ridge Is Taking Control

The reason for the increasing heat can be found several thousand feet above us.

An area of strong high pressure in the upper atmosphere is expanding across the Southeast and Tennessee Valley. This upper-level ridge encourages sinking air, which makes it more difficult for widespread clouds and thunderstorms to develop.

Sinking air also warms as it descends.

With fewer storms around to interrupt the heating process, temperatures have a better opportunity to climb during the afternoon.

The pattern is also beginning to push the track of the organized thunderstorm complexes we've dealt with recently farther north. That doesn't eliminate our thunderstorm chances, but it should reduce the frequency of the larger organized systems moving through our area.

Current guidance indicates temperatures across the region could run approximately 5 to 10 degrees above normal during the hottest portion of this pattern.

Humidity Makes the Heat Worse

The actual temperature only tells part of the story.

Humidity will remain high enough that the heat index could climb into the triple digits at times. The heat index combines temperature and humidity to estimate how hot conditions feel to the human body.

When humidity is high, sweat doesn't evaporate from your skin as efficiently. Evaporation is one of the body's primary methods of cooling itself, so high humidity makes it harder for your body to release heat.

That means an afternoon temperature in the middle 90s can feel considerably hotter.

Friday is a good example. Salisbury is currently forecast to reach around 95 degrees, but the heat index could climb to approximately 104 degrees.

Monday Could Be the Peak

Monday currently stands out as potentially the hottest day of this stretch.

The forecast calls for abundant sunshine and a high near 98 degrees in Salisbury. Nearby Charlotte is currently forecast to reach 100 degrees Monday, showing just how intense the heat could become across this portion of the Piedmont.

The exact temperature will continue to change as we get closer, and thunderstorms or leftover cloud cover could alter afternoon highs.

But the overall signal is clear: significant heat is increasingly likely heading into early next week.

Warm Nights Matter Too

Another part of prolonged summer heat that sometimes gets overlooked is what happens after sunset.

Overnight lows across Rowan County are expected to remain primarily in the lower to middle 70s during this stretch.

Those temperatures aren't record-breaking by themselves, but warm and humid nights provide less opportunity for buildings—and people—to cool down before another hot afternoon arrives.

When several hot days occur consecutively, the cumulative effects become increasingly important.

Thunderstorms Aren't Going Away

The strengthening ridge doesn't mean Rowan County will be completely storm-free.

Isolated to scattered thunderstorms will remain possible during the afternoon and evening hours. Saturday evening and overnight currently features one of the better opportunities, with rain and thunderstorm chances around 50 percent.

Any summertime thunderstorm that develops in this hot and humid environment could produce torrential rainfall and strong wind gusts.

The difference compared with earlier this week is that widespread organized storm systems may become less frequent while the ridge has greater influence over our weather.

Don't Underestimate This Stretch of Heat

Even if Rowan County doesn't reach 100 degrees, several consecutive days in the 90s combined with high humidity can become dangerous.

If you're spending significant time outside over the next several days, drink plenty of fluids, take breaks from the heat and try to schedule strenuous outdoor activities for the cooler morning or evening hours when possible.

Never leave children or pets inside a parked vehicle. Vehicle interiors can become dangerously hot within minutes.

The National Weather Service recommends staying hydrated, limiting strenuous outdoor activities during the hottest portion of the day and watching for symptoms of heat-related illness during periods of extreme heat and humidity.

How Long Could It Last?

There are indications that the upper-level ridge could begin weakening early next week, potentially allowing the favored storm track to shift farther south again.

Exactly when that transition happens remains uncertain.

Until then, expect the heat to be one of our primary weather stories across Rowan County.

Monday currently looks like the day to watch most closely, with an actual temperature approaching 98 degrees. I'll continue monitoring the forecast over the weekend to see whether those numbers trend higher or lower.

The dog days of August have arrived—and they're about to remind us exactly how they earned their name.
