I had light snow for about 10 minutes and I thought "Another bust", but then BOOM heavy blinding snow out of nowhere. I measured a legit 1 inch of snow on my cleared off porch. The rates were insane!!! It was well worth the wait. I don't like the looks of the US-222 accident, though. Very unfortunate.

Radar showing a thin line of yellows up your way.

not sure if Mt Holly has the ability to call for one yet.  There were only a few offices that were first rolling it out based on the post someone shared earlier

 

gotcha, i saw them issued earlier in western and central pa so I was wondering why they weren't expanded for our area. Seemed like a great way to get the message of danger out there. Thank god this isn't coming in a hour or 2 later...

Wasn't sure what the CWA cutoff is regarding where Reading falls but CCX was on the original list for roll-out of it last January.  Don't know what their phase-in schedule is for the rest of the stations but I thought this year was supposedly for all...

Edit - Eskimo Joe confirmed my thoughts!

"Effective on or about November 1, 2018, the NWS will transition a series of products from demonstration to operational status. These products include the highly localized, polygon-based Snow Squall Warnings and Dust Storm Warnings; a new zone-based Blowing Dust Warning; and a new polygon-based Dust Advisory product at all NWS Weather Forecast Offices (WFO)."

 

https://www.wnem.com/news/what-is-a-snow-squall-warning/article_5a5c2201-7df8-5763-b746-204bb12a4a7e.html

"It does have to meet a few criteria: A snow squall warning must meet whiteout conditions. That means visibility of a fourth-mile or less. You also need subfreezing road temperatures, which will allow snow to pile up quicker. A snow squall can only last 60 minutes or less. To qualify, it also must cause dangerous, life-threatening travel conditions on the roadways."

Oh no, heard the 222 accident is a Mass Casualty Incident (MCI) level 2.

 

MCI Level 2 – Incident will require local resources and responding agencies. Incident may require additional resources within the region.

  • Size – 10 to 20 patients
  • Hospitals – notification to local hospitals in area near location of incident and/or adjacent city or parishes
  • Triage – patients identified as RED, YELLOW, GREEN following START Triage guidelines and primary injury/service needed (LERN may be able to direct patients to specific area emergency departments with appropriate resources in small scale event)
  • Communications – primary: phone; secondary: radio. LERN Communication Center will assign a LERN Regional Tactical channel for transport operations when necessary.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Reduce your speed and turn on headlights! During snow squalls, the
visibility may suddenly drop to near zero in whiteout conditions.

There is no safe place on a highway when a snow squall hits.
Visibility and traction are immediately lost in whiteout conditions,
making it difficult or impossible to slow down and avoid stopped
vehicles. Delay travel or safely exit the highway before the snow
squall arrives.

Wet roadways will quickly freeze after passage of the snow squall.
Black ice will cause untreated roads, bridges and overpasses to
become slick and dangerous. Slow down and be prepared for sudden
loss of traction.
