York County under severe thunderstorm watch

Christopher Dornblaser
  • York County is expected to have warm weather, storms and potentially snow this week.
  • Strong storms are expected Wednesday, and snow is expected to hit early Friday.
  • Temperatures will warm up again next week.

10:45 a.m. Wednesday update:

The National Weather Service has issued a severe thunderstorm watch for 11 Pennsylvania counties, including York. The watch, which means the potential exists for severe  weather, is in effect until 5 p.m.

Reported earlier:

Yorkers will be dealing with "roller coaster" weather as temperatures are expected go from highs in the low 70s to highs of upper 40s this week, according to forecasters.

Additionally, a strong storm, which forecasters are saying could be similar to Saturday's storm, is expected to hit York County on Wednesday.

Aaron Tyburski, meteorologist for the National Weather Service in State College, said temperatures will be warm Wednesday before dropping into the 40s for Thursday and Friday. There is even potential for snow on Friday. Tyburski said the York area is expected to experience a "roller coaster" of temperatures.

He said temperatures are expected to climb back into the 60s by the start of next week.

Damaging weekend storm spawned tornado in York County

Storm: Dave Samuhel, a meteorologist for AccuWeather in State College, said the big thing to worry about this week is the storms expected to hit Wednesday.

“It looks like we’ll have some pretty heavy-duty thunderstorms in the area," he said.

He said the storms predicted for the York County area Wednesday don't look a lot different than the storms that hit the area Saturday.

“We’re probably not going to be as warm as we were on Saturday," he added.

The National Weather Service determined an EF1 tornado approximately 4 miles long and 100 yards wide struck near Hallam and Wrightsville during Saturday's thunderstorm.

“We don’t think there's a tornado to worry about," Samuhel said.

Tyburski said it was too early to say anything definite about tornadoes for Wednesday. He said tornado possibilities will be determined as the storms come through.

Samuhel said there is potential for damaging winds of  55 mph or more.

“I think people should just be aware that there’s another severe weather episode," he said.

Samuhel and Tyburski said the storms should hit in the afternoon hours on Wednesday.

Both meteorologists said the predicted storms  will come in fast, so people should just keep an eye out for any warnings.

"You just need to be weather aware and be prepared to take cover," Samuhel said.

Snow: Tyburski said temperatures will drop on Thursday, and then snow showers are expected to hit overnight into Friday.

“Thursday night it looks like rain and snow to start like around midnight," he said.

Samuhel said the same thing and added that the snow wouldn't be much if it hits.

“A weak low pressure could bring some snow showers Friday," he said.

He said if the snow hits, the area could see about an inch of snow at the worst.

Both said temperatures are expected to reach the 60s again at the start of next week.

“Anything that we did get, as light as it may be, will be all gone," Tyburski said.
