Thursday marks the first snow day in decades in which Philadelphia-area families aren't listening to KYW for news of school closings.

As news spread last month that KYW radio would stop broadcasting school closing numbers, Philadelphians looked back on those agonizing waits to hear whether their district would have a snow day.

Some had fond memories. Others mostly recalled frustration.

In the article's comments section and on Facebook, dozens of you shared your experiences of waiting for the magic snow day number. Many readers appeared able to easily recall their childhood district's number.

"545! Sweetest sound these ears have ever heard!" reader montanedelphia wrote.
"Ah man....another timeless tradition lost. I remember fondly listening to KYW in the mornings after a snowstorm, listening for that magical number: 653," reader Mtwon_Quaker commented. "Once I heard that wonderful number, there was a yell of delight, quickly dressing, grabbing my coat and wool cap....and off to Stokes Hill for a few hours of sledding. I miss those days..."

Some recalled their district's place in the radio line-up.

"454 here, nice and low, not long to wait to hear it...or not," wrote Band PSMac.

For some readers, the pain of hearing their number skipped apparently hasn't fully abated.

"I remember sitting in the kitchen as a kid hearing.... '310, 311, 312, 314, 315....' WAIT!!! What about 313?!!!?" HungryHippo wrote.
"I remember listening attentively and anxiously....only to hear my school number skipped!" Geoff Dennehy lamented.
— "We hardly ever closed."

Other readers, however, couldn't recall their district's number (suppressed memories?).

"I went to Upper Merion and I couldn't tell you the number if you waterboarded me," user Machete wrote." I don't know how you guys remember this stuff, but I'm impressed."

But the pure joy of mounting anticipation followed by the news of a sweet snow day was easily remembered by many readers.

"And they say some changes are for the better?? Not this!!!" Panthro2011 wrote. "What kid since the 70's didn't look forward to KYW announcing the number of their school on a snow day so they could look toward a day off from school and a day ON of play??? This is a sacrilege!!!!"
"I'm getting dressed slowly just waiting for that number." Mighty Dollar wrote of the snowy-morning routine.
— "And finally!!!"

And, of course, there were memories of snow-day calls gone horribly wrong.

Reader SpinMax recalled living a rural area with a director of transportation who "was so proud that we would have school when others would not... that was until a blizzardy day when most of us made it to school... and then by 10am they lined up the buses and took everyone home and she was never allowed to 'make the call' again."

In those big storms, painstakingly reading the number of every closed district was perhaps not the most efficient method, some readers noted.

"It was sometimes kind of silly because most of the time, all the schools were closed in a big storm, but they read all the numbers anyway," Mannaggia Keetamort wrote. "There should have been a point where they just read the numbers of schools that were open."

While many schools are notifying students and parents themselves of snow days, the end of the KYW broadcasts mean changes for some.

— "I'm a school secretary. Guess we'll have to update our handbooks and winter letters to parents. We've always told them to 'listen to KYW for school closing info'. Sign of the times."

But a phone call or tweet just might never seem as definitive as the old-school radio broadcasts.

As user Commenter wrote: "Even in recent years, when I'd get an email from the kid's school, I'd still listen for both 'my' school & theirs to make sure it was official."
