Calm cold crunchy, I'll see you at the top.

Amazing what just a 1" coating of fresh snow can do if the skies can clear with very little to no wind.  At 12:30am I'm down to 11.1 degrees and continuing to drop.  I think that anyone with several inches of solid snowpack will find their temps in the single digits come dawn.  I'll bet THV makes it down to zero.  Last week my coldest reading was +6.6 degrees F.  I think that's breakable.  We'll see...

Also, I melted down my snowfall, however I missed probably half of the accumulation because I didn't have my gauge outside on my board.  I recorded somewhere between 0.8" and 1.0" of snowfall, but all of that only melted down to 0.01" of liquid!  So, if you want to go with 80 : 1 SLR, I guess we can...lol.  There's no doubt this snow was high ratio, however, I think the highest ratio I've ever officially recorded was around 30:1.

Lots of single digits on personal weather stations this morning along the Susquehanna and in the Harrisburg area this morning. Coldest one I saw was +2 in Holiday Park near Linglestown.

Here in my backyard, though, I'm sitting at 14.

COLDEST DECEMBER 1-15 SINCE 2005 

Every single day of December 2025 has been cooler than average so far. The last day with above normal temperatures was November 26th (almost 3 weeks ago)! 

Fear not - the warm up starts today & continues through Thursday.

10 when I left the house but hit 1 on the car therm through the rurals. Also .2” of daily snowfall.

4.3 this morning.

Dropped into the singles if you don't do the official round up/down. 

9.9 at 7am.

[Blizzard of 93]

MDT is down to 9 this morning.

6 here. 

[pawatch]

6 degrees this morning. With a dusting of snow last night.

High yesterday was 22 degrees. 

[ChescoWx]

We had quite a few spots with lows in the single digits. The lowest was the 3.8 degrees at Warwick Township. The sun returns today and we should see some melting of the snow but with high temperatures remaining below freezing and the low sun angle it will be limited. Our much colder than normal December continues before we finally warm up to above normal on Thursday and Friday with rain arriving on Thursday night. Expect some fog over the melting snow with this system and most of the snow cover will be gone by Friday morning. Rain amounts could approach an inch in some spots. Looking ahead to Christmas week temperatures look to be not too far from normal for Christmas, but chances of a White Christmas look slim.

It’s going to be tough to get wintry precip before Christmas with the advertised pattern. Temps should be relatively seasonable after our few day warm up later this week.

The period between just after Christmas & before New Year’s showed some potential for chances on the 0z GFS. It looks potentially active, so hopefully we are on the right side of the boundary.

That’s great to hear! Many of us on here were thinking of you & rooting for your recovery!

I’m looking forward to tracking our next snow chance on here with you!

Smiling very broadly seeing you here. Very happy that you are feeling okay. Many of us have been thinking of you since last winter. 

[Itstrainingtime]

Measured .6" of snow yesterday evening. Season total is 5.4". Low this morning was 9.1. 

One of winter's greatest treats is early morning sun after freshly fallen snow. We've been treated to some spectacular scenes the past 3 mornings.

Interesting snippet from CTP's forecast discussion this morning: ( @canderson)

The biggest story on Friday will be the potential for strong to
damaging wind gusts. Building high pressure in the southeast US
will interact with the potent and deepening cyclone crossing
the Great Lakes to produce wind gusts exceeding 40mph Friday
afternoon in the wake of the cold front. Anomalously strong wind
fields could result in fairly widespread gusts of 40-50mph
across the northeast US Friday afternoon. Wind Advisories may be
needed for at least a portion of the area.
