The water-logged Charlotte region is getting a chance to dry out again Tuesday, as shower and thunderstorm activity is scattered for the second straight day.
But forecasters say they expect storms to develop later in the day in a few places, and they predict rainfall will become more widespread again later in the week.
Numerous heavy showers and storms late last week and over the weekend caused flooding along the chain of Catawba River reservoirs, and flood warnings remain in effect Tuesday for shoreline areas of Mountain Island and Lookout Shoals lakes. But water levels at Lake James, farther up the Catawba chain, were dropping Tuesday morning.
National Weather Service meteorologist Bryan McAvoy said some of the area could be hit by flooding rains again later Tuesday, when thunderstorms redevelop in a humid and unstable air mass. But he said that will cover just “a fraction” of the area.
Similar conditions are expected Wednesday, with scattered afternoon and evening thunderstorms. This week’s storms are moving slowly, which is increasing the flooding risk.
At 8:30 a.m. Tuesday, Weather Service meteorologist Doug Outlaw said the water level at Mountain Island Lake was 2.4 feet above full level. He said that indicates flooding is continuing at docks and in some yards along the reservoir. The level at Lookout Shoals was about 2.1 feet above full level, and Outlaw said flooding also is continuing there.
By Thursday, another upper-level low pressure system could develop over the Carolinas. That would enhance the thunderstorm activity and possibly cause another round of flooding.
Temperatures over the next few days are expected to be a little below seasonal averages, with highs in the mid to upper 80s. Humidity levels will be very high, however.
