The ozone stuff might have something to do with it, but it seems far-fetched that the strength of the sun itself has changed that much over the course of (half?) a human lifetime.
EC gives us yet another possible solution for Christmas: a west-to-east low moving across the Mid-Atlantic. Too warm for snow, but closer to the solution we want?
Would think today’s record high of 64 is in play if we get some sun. Last year, PIT set a record snowfall of 9.3” on today’s date. What a difference a year makes.
Edit: looks like 64 was reached just after noon.
The only thing I’ll add about “normals” is this, and I think I’ve said this before: seasonable temperatures are just fine if you don’t simply oscillate between normal and well above normal like what seems to happen a lot. The last time MDT recorded a negative double digit temp departure for a day was way back on 6/23. How many double digit positive departures have occurred between then and now? 22.
As @MAG5035and @Blizzard of 93alluded to, highs in the 40s are considered normal for parts of winter, but here’s the top 10:
Note that 8 of these have occurred in the past 30 years.
I always enjoy these posts. The Zapata, TX reference reminds me of a PM I once got from someone inquiring about the September record high for the state of Texas because it was 107 in Zapata that day.
