PITTSBURGH (KDKA) – A winter storm system is moving towards the area, and that could mean slippery conditions Friday.

The National Weather Service has issued a Winter Weather Advisory beginning at 5 a.m. for all of Western Pennsylvania.

“So the time period in question for potential travel problems would be [Friday] morning,” said KDKA Chief Meteorologist Jeff Verszyla. “That is when the Winter Weather Advisory goes into effect at 5 a.m. It includes all of Western Pennsylvania, most of Ohio and West Virginia.

The storm will move in Friday morning, and will start as a wintry mix, with freezing rain, sleet and snow.

“Once it starts, there will be some mixed precipitation arriving around 7, 8 o’clock [Friday] morning,” said Verszyla. “The temperature will come up between now and then and we’ll list 27 as the wake-up temperature, but still below freezing.”

The brief period of snow and freezing rain will eventually change to all rain showers as the temperatures then climb above freezing.

Verszyla says we shouldn’t see much snow accumulation.

There could be a light glaze of icing due to the freezing rain before it changes over to all rain.

“We’re probably looking at a six or seven hour window when we’ll see the precip falling across the area before a warm front lifts through, and you’ll notice by 5 o’clock [Friday] the precip is either off to the east or off to the north, and we get into a, kind of a hole if you will, a quiet area with no precipitation,” Verszyla said.

Friday’s high temperature will be 38 degrees with breezy conditions.

Saturday looks partly sunny with a shower possible and a high of 43 degrees.
