Update: A Winter Weather Advisory is in effect in York County from 2 p.m. Monday until 1 a.m. Tuesday, according to the National Weather Service.

Light snow will give way to heavier, mixed precipitation later Monday, according to a weather service update released at 5 a.m. today. Between 2 to 4 inches of accumulation is now expected before the snow transitions to freezing rain for most of the area Monday evening.

Precipitation should turn into regular rain after midnight, but hazardous travel conditions are expected during Monday evening commutes.

The rain is expected to continue throughout Tuesday, according to NWS.

Reported earlier: Monday evening’s commute home from work might be slick, according to the National Weather Service.

York County can expect snow to start in the afternoon with 1 to 2 inches of accumulation, said Richard Grumm, NWS meteorologist in State College.

“We can expect some flurries throughout the afternoon mixed with freezing rain into the evening,” he said. “Tuesday morning it should be all rain. We’ll see temperatures in the mid-30s on Tuesday.”

Steve Travis, meteorologist at Accuweather, said the York County area is looking at around 1 to 3 inches of snow, which will start coming down between 3 and 5 a.m. Monday. He said it will be turning into wintry mix in the late afternoon, followed by straight rain.

"The first half of (Monday) night could be really dicey," he said, adding that forecasters don't know exactly when the ice will stop. As of Sunday night, he said they are looking at the ice stopping around midnight.

Accuweather meteorologist Tim Kines confirmed the snow should turn to all rain by Tuesday during the day.

“It depends on when the change-over to rain happens,” he said. “It looks like there could be some slick travel Monday afternoon. By the time people wake up on Tuesday, it should just be all rain.”

Grumm echoed Kines comments of slick roads, saying people should get errands done on Monday morning before the snow starts.

“There could be some messy, dangerous roads Monday afternoon because of the snow,” Grumm said. “If there’s freezing rain out there, don’t go out if you don’t have to.”

The rest of the week should get back to normal temperatures for this time of year, Grumm said. Nights will be below freezing, and days will reach highs in the upper-30s to low-40s.

Temperatures might fall back into the freezing-rain range by Wednesday morning, Grumm added.

Both Grumm and Kines said there should be warmer weather on the way by next weekend. Temperatures could be as high as the mid-50s by Saturday.

The director of the Pennsylvania Emergency Management Agency, Richard D. Flinn, has ordered the PEMA State Emergency Operations Center (SEOC) to activate to level 3 starting at noon Monday, according to a news release.

The activation includes enhanced watch, situation awareness section, planning section, logistics/resource support section, center support, bureau of technical services and public information staff.

The rain and rising temperatures could potentially lead to small creek and stream flooding, according to the release. The SEOC will monitor and communicate with counties and state agencies to respond to any needs if incidents should occur.
