Monday’s sunshine across the Rock Hill area was just a tease, forecasters say.
Another round of heavy rain is expected by nightfall, and more rain and thunderstorms are predicted for Tuesday and Wednesday.
This comes on the heels of the 2.67 inches of rain that fell Sunday in Rock Hill. The precipitation was spotty, with 3.95 inches reported at the airport in Chester but only 0.60 inches at the Lancaster airport.
The National Weather Service has issued a Flash Flood Watch until late Wednesday night for York, Chester and Lancaster counties. The Weather Service’s Justin Lane said early Monday afternoon that 2 to 3 inches of rain, with locally heavier amounts, is expected over the next few days in the area.
Sunday’s rain washed out a portion of Connor Road near Lowrys in northwestern Chester County, said Eddie Murphy, Chester County Emergency Management Director. The road is blocked at the spot, Murphy said.
Connor Road connects at its eastern terminus to U.S. 321, just south of the York County line.
“This road has ways in and out on both ends, so no one is stranded,” Murphy said. “We had reports that it was close to 3 inches over there in that area.”
It remains unclear when county officials will fix the road, as more rain is expected this week, Murphy said.
The next area of precipitation, a large cluster of heavy showers and thunderstorms, was over southern Louisiana and Mississippi on Monday morning and expected to reach the Rock Hill area by evening. Areas near the center of that low pressure system will get the heaviest rain, forecasters say.
Before that system arrives, a few thunderstorms could develop in the muggy atmosphere Monday afternoon. Some of those storms could have strong wind gusts, forecasters say. There could be another lull for a few hours late Monday evening before the Gulf system arrives.
“The bigger concern remains the heavy rain threat,” said Trisha Palmer, of the National Weather Service office in Greer.
She said some of the computer guidance shows more than 2 inches of rain falling between 4 and 8 a.m. Tuesday in the Rock Hill-Charlotte corridor. Additional rain is forecast after that.
Palmer said rainfall likely will taper off by Tuesday afternoon and evening, but yet another low pressure system is forecast to develop and move across the Rock Hill area Wednesday.
There is good news for people with plans over the Memorial Day weekend. By Thursday, thunderstorm chances will decrease to 30 percent, and full sunshine is predicted to return by Friday and continue through at least Sunday.
Temperatures, which will only climb into the low and mid 70s from Tuesday through Thursday, will rebound by the weekend and be back in the upper 80s for highs by Sunday. The next rain-producing system is possible in a week, on Memorial Day.
