Charlotte’s weather: Rain, warmup tonight, and possible storms

Rain is falling Sunday afternoon across the Charlotte region, and meteorologists say there is plenty more to come – along with the possibility of some thunder later this evening.

The evening hours also will mark a change in temperatures, as a warm front is predicted to pass from south to north across the area. That means our warmest weather Sunday will come near the end of the day.

The rain arrived earlier than expected, pushing into the Charlotte region around 4 a.m. More than one-third of an inch had fallen by 1 p.m. at Charlotte’s airport, and National Weather Service meteorologists said another 1 to 1.5 inches could fall before the precipitation ends as showers in the early-morning hours Monday.

In the meantime, readings were in the upper 40s early Sunday afternoon, and forecasters said they expect little change until the warm front arrives this evening.

The warm front’s arrival could bring an increase in thunderstorm chances.

Meteorologists said Sunday that winds in the atmosphere behind the warm front will be blowing from different directions at various altitudes. That effect is called wind shear, and it is one of the factors that can create severe thundestorms and tornadoes. Another important factor is instability, and forecasters said they aren’t sure if the atmosphere will become that unstable Sunday evening.

Should that happen, however, the Charlotte region – especially south and east of the city – could be at risk of heavy rain and damaging wind gusts.

Temperatures will be much warmer early Monday morning than on Sunday afternoon, with readings likely climbing into the lower 60s after midnight.

Monday is forecast to be warm, with highs near 70. But another cold front will cross the region later in the day, dropping temperatures back to below-average levels through Thanksgiving.

Krentz said computer guidance “is fairly certain” about a low-pressure system forming Wednesday along the coast, but it is not clear whether the storm will be close enough to the coast to cause bad travel weather in the Charlotte area.
