Central PA Winter 25/26 Discussion and Obs

[Superstorm]

I got down to 3.6F but the winds never went calm so no robust radiation cooling.

Busted way high.  7 was my low.  

[Blizzard of 93]

Low of 4 in Marysville. My coldest morning of the season so far.

Skies went overcast in parts of the state, plus a light breeze that helped to keep temperatures up a bit.

Similar deal here.  Got to exactly 0 at 3:00 AM but then rose to 5 when a little breeze came through.  Now back to 2.  

Local WU site bottomed at -1.7 at 7:20.  

Even with geothermal, looks like a $300 electric bill next month.  First time in the 26 years we've lived here.

Got down to -1.1 on the York station and -3.1 on the Mount Joy station.

Low of 5 here. Winds and clouds have been just fickle enough throughout recent nights to prevent total bottoming out, and have also lead to some unusual times for the lows.

Accuweather had -9 for me when I woke up and checked the AM. Was -6 yesterday AM. 

Still shows -5 on NWS page. I know it sure seemed like the coldest night so far by the way the furnace ran all night.

What gives? I'm overcast and actually have some very light snow/flurries falling here in Tamaqua.

Ensembles all look active with Winter Storm chances from later this week through the end of their 15 or 16 day runs.

My low was 6.6. As I mentioned yesterday morning, I was concerned about cloud  over overnight.

It's been a very cold week. Sub-freezing temps wall to wall. And yet despite the fresh snow cover from last Sunday's storm this week fell quite short of modeled low temps here. My temp never fell below 5 degrees. That's at least a double digit departure about what at least some models indicated. I think it was @CarlislePaWx who shared an image last week showing MDT getting down to -19 this morning.

Friday morning was the only morning I ended up below zero here (-3 or -4ºF), I got to exactly 0.0ºF last night. Light influences from the developing coastal in the form of light wind and cloudcover as you mentioned likely kept things from fully decoupling. Still been a heck of a cold stretch, when the temps likely fail to reach 20ºF again here today that will break the longest streak of days under 20ºF for KAOO that goes back to 1948 for that station. That was 7 consecutive days set in Feb 1979, and today will make the 8th day. 

The lows in western PA the last few nights have been wild where there has been ideal radiational cooling conditions. For official ASOS stations, the coldest I saw for last night was -20ºF north of Pittsburgh at Zelionople Municipal Airport (KPJC).

A few places touched zero this morning including the icebox of Chester County the Warwick DEOS station that set an all-time record low with records back to 2012 of 10.7 degrees below zero. The old record was 9.1 below zero on January 22, 2025. Our impressive cold stretch continues through the weekend with today being our 8th straight day of sub 32 highs. This is tied for 8th longest streak since 1893. Our best chance to end the streak and get above freezing looks to be on Tuesday with the NWS forecasting a high of 30 degrees. January will end as our 4th consecutive below normal temperature month and our 9th below average month in the last 12 months dating back to December 2024. Could we be entering our next climate cooling cycle here in Chester County?? While cold most of the next week looks dry but there could be a couple chances of some snow toward midweek and again next weekend.

It really depends what your local conditions were like for how low you went last night. A good bit of variety across the local ASOS stations: RDG 5, CXY 4, LNS 1, MDT 0, and THV -8. I believe MDT’s zero reading will be a new record low for today, breaking the previous record of 2 from 1948.

How far is Harrisburg running below normal so far this month?

[canderson]

In Manhattan and if you hit subnets hit miserable out given no wind
