Total snow and sleet accumulations up to two inches and ice accumulations up to two tenths of an inch. * WHERE...Most of central Pennsylvania. * WHEN...From noon Friday to 7 AM EST Saturday. * IMPACTS...Plan on slippery road conditions. The hazardous conditions will impact the Friday evening commute. * ADDITIONAL DETAILS...Much of the precipitation could fall as sleet. Sleet and freezing rain can both be dangerous, especially on bridges and sidewalks. They can also weigh down tree limbs and power lines. Power outages are possible.

Lol, with temps in the 20s & at least .3 of precipitation on the way…? Maybe it will be 80 tomorrow & we can jump in a swimming pool too?

The only probability scale that we should be using is the fact that any models forecasting warmth in week 2 or beyond have been wrong this season. Cold has won out since Thanksgiving this year. We will have our chances to score.

I’m expecting a disaster on the roads. Lots of people off of work will be out shopping, using restaurant gift cards & continuing holiday get togethers. Too many people with the “it’s not so bad” attitude could be involved in holiday fender benders.

12z Euro showed a chance on January 6th. We should have our opportunities.

Temps on both Euro & GFS are still in the 20s for most of us tomorrow early evening at 7 pm.

Exactly, we are not getting near freezing tomorrow. Conditions won’t improve until Saturday am. 18z Euro says majority is freezing rain. 18z GFS says majority is sleet for us.

12z Euro still sees this as primarily a freezing rain threat for most of us. Some have mentioned the Euro struggles to see sleet, so it will come down to the upper level temperatures. Surface temperature at the height of the storm tomorrow evening are in the 20s for most of us, so whatever falls will be a problem on the roads.

12z HRRR gets a good amount of sleet into most of CTP & the decent snow line this run gets into a good portion of Dauphin, Lebanon & Lancaster county.

Still nice to have this even though it’s a mix mess… Winter Storm Watch URGENT - WINTER WEATHER MESSAGE National Weather Service State College PA 213 AM EST Thu Dec 25 2025 PAZ004>006-011-012-018-019-026>028-035-036-045-049-050-056-057-059- 063>066-252100- /O.CON.KCTP.WS.A.0012.251226T1200Z-251227T1200Z/ Warren-McKean-Potter-Cameron-Northern Clinton-Northern Centre- Southern Centre-Huntingdon-Mifflin-Juniata-Fulton-Franklin- Southern Clinton-Union-Snyder-Perry-Dauphin-Lebanon-Cumberland- Adams-York-Lancaster- Including the cities of Lock Haven, Mifflintown, Emporium, Warren, Chambersburg, Renovo, Selinsgrove, Bradford, Mount Union, Newport, Lewistown, Lebanon, Carlisle, State College, Lancaster, Harrisburg, Philipsburg, Lewisburg, Gettysburg, Huntingdon, Coudersport, Hershey, York, and McConnellsburg 213 AM EST Thu Dec 25 2025 ...WINTER STORM WATCH REMAINS IN EFFECT FROM FRIDAY MORNING THROUGH SATURDAY MORNING... * WHAT...Heavy mixed precipitation possible.

Merry Christmas everyone!

Remember around Thanksgiving when we thought we were going to lose the first 2 weeks of December & then things would look better towards mid month…? Reality is that we had well below normal temps & most have had a couple of measurable snow events. This upcoming pattern looks variable with chances if of course the timing & track are right.

That was a little over a week after many of us got around 10 inches of snow that got wiped out by the storm you are referencing.

12z GFS is bringing .50 to .75 of precip into the cold dome. Hopefully heavy rates at the start can put down a little snow before the warming aloft kicks in, but it that amount of sleet would be impressive.

For those of us team heavy sleet, the 12z GFS delivers around 2 inches of sleet in the LSV on Friday with minimal freezing rain this run.
