A winter storm expected to hit Lancaster County on Saturday will be a messy one, according to the latest forecasts.
AccuWeather's prediction shows snow of varying intensity starting in the morning and accumulating one to three inches, followed by a touch of rain over several hours in the evening.
"It’s going to be messy Saturday, it’s going to be treacherous to travel," said Millersville University meteorologist Eric Horst.
The day will start cold, possibly with temperatures in the 20s, he said, and he expects the storm to start as snow. But, he said, much warmer air will be coming in above the ground, so he's predicting snow will switch to wintry mix, possibly quickly, and expects drizzle by early evening as temperatures hover around freezing.
Horst predicted that temperatures would fall back below freezing midday Sunday, dropping into the teens overnight, with daytime highs Monday and Tuesday in the 20s before the weather moderates later in the week.
A winter storm will affect Central PA on Saturday. Precipitation will start as snow and then change to a wintry mix of sleet/freezing rain during the afternoon. There is considerable uncertainty in these amounts, depending on the location/duration of wintry mix.

If snow is your thing...then the model trend is NOT your friend with this upcoming storm. The likely track continues to shift northward...which means less snow and more ice and rain. Still, a sloppy, icy mess will make Saturday midday/afternoon a dicey time to travel regionwide.— E. Horst, MUWIC (@MUweather) January 15, 2020
As I Tweeted yesterday, it's foolish to play the numbers game w/ a "change over" storm 5 days out. But do expect some snowy/slushy travel Saturday...mainly btwn 9am - 6pm. This is NOT a crippling snow event and it will clean up quickly...with a cold, dry Sunday & Monday.— E. Horst, MUWIC (@MUweather) January 15, 2020
Where's winter? It's going to make a KC Chiefs-like 2nd Quarter comeback at the end of this week. And while this trend may continue into February, I'm not prepared to predict a winner of the game we call "winter." Stay tuned... pic.twitter.com/YjIlIjYdOX— E.

After a relative dry period, some storminess is in store for Central PA for late week into the weekend. Here is a 7 day forecast of liquid precipitation (rain and/or melted snow) for the period ending next Tuesday evening. The blue over PA indicates 3/4 of an inch or more. pic.twitter.com/cbGCquK7pw— NWS State College (@NWSStateCollege) January 15, 2020
