Saturday Turning Wet Across the Region — Widespread Showers and Storms Expected

After several days of sunshine and building late-summer heat, a much wetter pattern is expected to develop across the region as we head into the weekend.

For Rowan, Davie, Davidson and Cabarrus counties, Saturday currently stands out as the wettest day of the forecast period, with widespread showers and thunderstorms expected to develop.

Sunshine and Heat Come First

Before the rain arrives, Thursday will bring plenty of sunshine with afternoon temperatures climbing into the lower 90s across much of the region.

The heat and humidity increase further Friday. Afternoon highs are expected to reach the lower 90s, with Cabarrus County potentially reaching around 93 degrees. Increasing humidity could push heat index values toward 100 degrees in portions of the Charlotte metro.

Friday will not be completely rain-free, but coverage should remain limited. An isolated shower or thunderstorm could develop during the afternoon or evening, with rain chances generally around 20 percent during the day before increasing Friday night.

Saturday Is the Main Weather Day

The bigger change arrives Saturday as a weakening frontal boundary interacts with increasingly moist air across the Carolinas.

Showers could begin developing during the morning, but coverage should increase considerably as we move through the afternoon.

By Saturday afternoon and evening, widespread showers and thunderstorms are expected across much of the region.

Current rain chances are around 80 percent for Rowan, Davie, Davidson and Cabarrus counties.

Temperatures will also be lower because of increased clouds and rainfall, with forecast highs ranging from the mid to upper 80s.

Locally Heavy Rainfall Possible

There will be plenty of moisture available for Saturday's thunderstorms, meaning some storms could produce locally heavy downpours.

The greatest concern would be locations that receive repeated thunderstorms or particularly heavy rainfall over a short period.

Across Davidson County and areas farther east into central North Carolina, there is a Marginal Risk for excessive rainfall Saturday. This means isolated flash flooding will be possible, particularly in urban areas and locations with poor drainage.

Farther west, including Rowan, Davie and Cabarrus counties, the flooding signal is currently less concerning. Much of the rainfall could be beneficial given the recent dry conditions.

However, rainfall from thunderstorms is rarely distributed evenly. Some communities could receive considerably more rain than others.

Severe Weather Threat Remains Low

Despite the expectation for numerous thunderstorms Saturday, the severe weather threat currently appears very low.

One of the main limiting factors will be weak wind shear. Forecast guidance indicates only around 15 to 20 knots or less of deep-layer shear, which makes it more difficult for thunderstorms to become organized and sustain themselves as severe storms.

That doesn't mean an individual thunderstorm couldn't produce gusty winds, frequent lightning or very heavy rainfall. It simply means the overall environment currently does not favor an organized severe weather event.

What About Sunday?

Saturday night's showers and thunderstorms should gradually decrease, with improving conditions expected Sunday.

Sunday is currently forecast to be partly sunny across much of the region, although Davidson County retains a small chance for an afternoon shower or thunderstorm.

Temperatures will quickly begin climbing again as we move into early next week, with upper 80s returning by Monday.

The Bottom Line

If you have outdoor plans this weekend, Saturday is the day you'll want to watch closely.

Thursday stays sunny and hot, while Friday brings increasing humidity and only a small chance for a late-day shower or thunderstorm.

Saturday is a different story.

Widespread showers and thunderstorms are expected, particularly during the afternoon and evening. Locally heavy rainfall will be possible, but the overall severe thunderstorm threat currently remains low.

There is still time for the timing and rainfall amounts to change before Saturday. Rowan County Weather will continue watching the latest forecast guidance as higher-resolution models provide a clearer picture of when thunderstorms are most likely to develop and which areas could receive the heaviest rainfall.
