Update: The National Weather Service will lift its flood warnings in York County at 2 p.m. Friday.

The area has received between 2 and 3 inches of rain, said Paul Head, a meteorologist with the National Weather Service.

No more rain is expected for the county this weekend, though there may be a few light sprinklings on Saturday, he said.

From Friday night to Saturday morning, low temperatures will be in the low 40s, according to Head.

High temperatures on Saturday and Sunday are expected to be between 65 and 70 degrees, with lows in the 40s both days, Head said.

Update: The National Weather Service has issued a flood warning for western York County until 9 a.m. At 6:30 a.m., the weather service said bands of heavy rain will fall through 10 a.m. The system was moving north at 40 mph, causing standing water on roadways. Motorists were urged to use caution and stay away from flooded areas.

York County could receive about half the amount of rain it typically sees in a month in just a matter of hours thanks to a storm pushing up the coast.

A slow-moving storm that started Thursday night and is expected to last into part of Friday could bring 1 to 2 inches of rain, said Rich Jaworski, an AccuWeather meteorologist.


If the higher end of the spectrum falls on the county, it would be about half the amount of rain typically recorded at the York Airport in Jackson Township in May.

Jaworski said the airport typically sees 4.19 inches of rain in May.

However, the storm could bring higher amounts locally, with the western part of the county expected to bear the brunt of the storm.

"It wouldn't surprise me if some portions of the state, including York County, picked up 3 to 5 inches," Jaworski said.

The amount of rain forecast prompted the National Weather Service on Thursday to issue a flash flood watch that runs until 8 p.m. Friday.

The storm: The National Weather Service says the weather system was expected to produce torrential downpours and thunderstorms as it moved through the region Thursday night into Friday.

"This is sticking around from (Thursday night) through the better part of (Friday) morning," Jaworski said.

He said he expects the heavy rain to come to end mid- to late morning but added there's a chance for a shower later in the day before the storm moves to the east.

The downpours will reduce visibility and lead to ponding on roads and other areas with poor drainage.

The heavy rain could cause water levels of creeks and streams to rise quickly, and flash flooding is a possibility, the weather service says.

A flash flood watch means that conditions may develop that could lead to flooding.

Friday's high is expected to be 68, with a nighttime low of 43, according to AccuWeather.

After the storm: But once the storm passes, part of the weekend will be sunny and typical of spring.

Saturday will be mainly sunny with a few clouds and an expected high of 70 and low of 41.

Sunday will be a bit cooler with a high of 68, low of 40, a partly cloudy sky and a passing shower in the afternoon, according to AccuWeather.
