Central PA Winter 25/26 Discussion and Obs

[Mount Joy Snowman]

Low of 9 here as it looks like a pretty substantial inversion setup last night, with a wide variety of lows around the area.  @Itstrainingtime at one point earlier this morning I was scanning WU and the Maytown airport station near you was at 15 while some station like a mile or two to its west was at 3.

Today, across multiple sites in Chester County will be the 13th consecutive day with below freezing temperatures. This is already the 3rd longest streak since 1893. These locations should establish a new prolonged cold record on Monday which will be the 17th day. Also, today will be the 20th consecutive day with continuous snow cover. This is the 22nd longest stretch with snow cover since 1893 and our longest streak since the 32 days from January 31, 2021 through March 3, 2021. Our greatest stretch was the 61 days back in 1978 from January 12th through March 13th. We continue with well below normal temperatures through early next week. An arctic cold front crosses the area overnight Friday into Saturday morning likely to bring potentially brief heavy snow squalls with an inch or two of snow possible in spots with briefly poor visibility and driving conditions. Highs for Saturday will occur just before dawn with temperatures then crash into the single digits during the day with wind chills in the minus teens below zero. What a memorable winter this has already been and we still have more than 6 weeks to go!

could cause frostbite on exposed skin in as little as 30 minutes.
Frostbite and hypothermia will occur if unprotected skin is
exposed to these temperatures.

* ADDITIONAL DETAILS...An arctic front will bring cold air and
strong winds to the region Saturday morning. Below normal
temperatures and blustery winds will result in wind chills
dropping well below zero Saturday morning. Wind chills will remain
below zero through the rest of the weekend.

Im headed to the cabin snowmobiling tonight.  Guess I dont have to worry about trail conditions deteriorating....lol

Low of 7 in Marysville.

since temp talk has been a topic of late, I paid a little extra attention to digi thermo on ride to work today.  27ish mile trip.  Lowest number 1....highest...13 (730 am).

Thats the variability that many of us know exists when peeps give their backyard readings.  

looks like etown went from 3.9 to 15 in 2 hours.

05	08:56	NW 9	9.00	A Few Clouds	FEW250	15.1	7			70%	4		30.16	1022.0

lol.  i just posted a response to Blizz about the same thing.  

Looks like pattern to get active next week, with warm and not white for first event.  Hopng that one sets the table for Blizz's VD weekend event.  Hoping y'all get snowed in w/ your loved ones.

Looks like the high temp. will be in the early morning hours on Saturday. Both the Euro and GFS have temps. near 10 or single digits during the rest of the day. Don't know why NWS is downplaying the winds either as euro and gfs have gusts over 40mph.

[pasnownut]

I'll add that after review of the overnighters, the concensus is that storm 1 looks icy/wet, and there is no consensus for next weekend VD event.  Couple snowyish solutions and couple warm ones.  Op/ens guidance have notable differences at 500.  Need to iron that out till we can get an idea of what n where this goes.

I met my son at the Nook this morning for some early hoop action. Driving across Prospect Road from 283 to Washington Boro my car fluctuated between 4 and 21. 

I was surprised to see how low I got last night.

6z GFS for next weekend has a snow to mix/rain back to snow long duration scenario for CTP.

Long way to go & many developments still to come in the upcoming days as we continue to track the potential.

Middle of the uprights scenario right there.

Overnight Canadians were friendly to us - certainly looked like it was going to be a flush hit. 

Euro as depicted was very concerning to me. It drove temps into the 40s clear up to Montreal while I basked in the mid 50s during a driving rain storm. That would spell significant concerns along the Susky for ice jam issues...

CTP seems to think the clipper does not do anything in Harrisburg. 

par for the clipper course down here in LSV.  We've seen things look good from afar (timewise) only to have things diminish as we get into short range.  Not surprised at all.

 

And one should keep this in mind as we move into a more volatile period w/ NS/SS battling is out and we loose the heavy hand of cold.  Might be a bumpy ride.
