So... If I'm reading this right the light blue area is 8" to 10" ending the 24 hour period ending Sunday MORNING- not the entire event! Watching closely! #PAwx

Winter Storm Watch? Yeah, we're watching it.

Just in time for the winter storm, the Pennsylvania Forecast Page has a fresh new update! #PAwx stormsellweather.com/weatherwall/...

CTP issues Cold Weather Advisory valid at Jan 23, 10:00 PM EST for Adams, Cumberland, Dauphin, Franklin, Lancaster, Lebanon, Perry, Schuylkill, York [PA] till Jan 24, 10:00 AM EST Link

Ice is flowing down the Susquehanna River in Harrisburg. There will be more ice forming over the next week. #PAwx Webcam: www.srbc.gov/susquehanna-...

I'm surprised we don't have a Wind Advisory. #PAwx

Parts of New York are on track to have their longest-continuous Winter Storm Warnings on record... again. The local National Weather Service has used Winter Storm Warnings instead of Lake Effect Snow Warnings since mid-December. Since then, parts of their region have broken this record twice now!

As Euro ensembles gradually come into better agreement on their swath of heaviest snow, the Euro EFI becomes very useful. It tells us how unusual & extreme a specific weather variable can be based on thousands of reforecasts over a 5-week period centered on that day.

Some thoughts on the upcoming storm. The storm will be a long duration with snow falling for more than 24 hours. Avoid travel on Sunday & into Monday. This will be a light, fluffy snow. 2 feet in spots is not out of the question. Any wind will cause drifting. Lots to watch in the coming days.

10 years ago today 18" to 24" fell in southern Pennsylvania! ☃️ #PAwxHistory

Good thing it warmed up last night or all the snow would have blown away.

This picture making the rounds on reddit, Columbia Heights. I'm not OK.

Snow squalls tomorrow morning. Guess we'll be adding to the Snow Squall Warning total. #PAwx

4.2"! May add a bit more, too. Totally awesome considering this morning I only expected about 2". Makes up for some of the snow we missed out on. Highest total of the season so far beating 2.7" on 12/2. Let's beat it again Sunday!

Roads are snow covered in Altoona for those heading home. 🌨️ #PAwx Also: TURN YOUR HEADLIGHTS ON! Webcam: www.abc23.com/renewal-by-a...

After being on the outside looking in for number of snow events in eastern PA lately it is nice to be getting something. But it also helps that there is a significant one coming, too!

Live view from Somerset where the snow is coming down. The commute home is going to be slow for many this evening. #PAwx Webcam: wjactv.com/weather/seve...

Besides some Air Quality Alerts and Dense Fog Advisories, the weather is quiet.

👀👀👀 #PAwx

I find it odd that you can mping drizzle or rain, but you can't mping flurries, just snow.

Winter Weather Advisories have been expanded. #PAwx

The choice is impeachment and removal or calamity for the United States. I don't see how anybody watching Trump's speech in Davos can draw any other conclusion. He's a senile madman.

No one can be watching this Davos speech and reach any conclusion but that the President of the United States is mentally disturbed and that something is deeply wrong with him. This is both embarrassing and extremely dangerous.

Latest guidance is bringing the axis of highest snow totals further south for the system moving through tonight. Something to watch. #PAwx

Weather apps irresponsibly predicting 18" for an area that won't get 18" for a storm that is 3-4 days out is causing unnecessary panic and stress. STOP.

This storm could bring some beneficial precipitation to the Keystone state. Parts of south central PA have yet to pick up half an inch of precipitation this month. The past 6 months have been dry statewide. #PAwx

Lancaster dropped to -7° (official low) this morning. This is the coldest temperature recorded at the Lancaster Airport with records going back to 2000. #PAwx Previous record was -6° on 1/22/2025.

It was cold this morning but not as cold as one year ago. #PAwx

GoPro timelapse of the northern lights tonight.

Struck out on the Northern Lights in #pittsburgh last night but just after sunset today they sure put on a show. Absolutely amazing to see these over the city…they were so bright and visible to the naked eye. Can’t wait to share more.

I started my GoPro at 6:36pm. Here is what it captured at 6:44 while I ate supper. I just caught the tail end of it when I went outside at 6:46.

Here are the best shots form the PEMN webcams of the northern lights *from this morning*. Working on gathering the images from this evening. #PAwx

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

Bundle up if going out to look for the northern lights. If you don't see them, it is a great night to stargaze. #PAwx

High & low temperatures over the past 24 hours. #PAwx

Webcam images from northern PA. #PAwx

Bright substorm just after sunset for the U.S. east coast sent pillars high in the sky that likely could have been photographed from far away central U.S. states like PA, VA, MA, etc. go.theauroraguy.com/webcams

WOW!

I was going through the webcam archives looking at the northern lights this evening and discovered these ice pillar shots from early this morning! #PAwx climate.met.psu.edu/data/pemn/?s...
