There were weather stations in northern Butler County in the -25 to -30 range this morning. Of course, we didn’t radiate nearly that well down here.

Interested to see if we get better radiational cooling conditions tonight and/or tomorrow night and see how cold we can go, or if it’ll just be kinda meh like the last few nights.

Yeah the other day I was out for a walk with the dog and it was snowing and there was barely a cloud in the sky.

I’d question whether we “officially” get below zero any mornings other than Friday and Saturday, which look like slam dunks, but even those don’t look like spectacular radiational cooling nights. We just don’t do radiational cooling well in this region in general due to cloud cover, but the airport does it especially poorly.

Record is 7 in Feb 1899. We had 6 in Jan 1936 and a bunch of years with 4 (most recently the 1994 one that includes our all timer of -22).

The problem is, with the liquid equivalent and snow accumulation being observed at different sites, we don’t really have an apples to apples comparison. @TheClimateChanger does the NWS office have some sort of ASOS/AWOS or just snow obs and that’s it?

This would be brutal.

For those hours when the NWS was adding .4” to the total, the airport ASOS station was recording .08” liquid equivalent. Did our ratios drop as low as 5:1?

At the end of the day I’d take another 2016 over something like 1/19/19. It could be a whole lot worse than getting a high end advisory snowfall.

First off, this was a deeply satisfying storm and I got just a hair over a foot imby, and it sounds like many of us did. It seems the official obs is consistent with a lot of the other obs in the western part of the county, so I don’t think I have an issue with the measurement itself. I’ll agree that the calendar day thing is a bit silly, so let’s go by individual storms instead. Pittsburgh has had 27 two-day official storm totals of 12”+, most recently, of course, in 2010. The 16 years (and now still counting) that have passed since our last one is still the longest drought by that metric. With that being said, it’s only January 25 and we’re only about 8” away from getting our first above normal snow season since 2021-22, and that one was only because we lucked into above normal with some late season stuff. We’ve had two winter months with below normal temperatures and above normal snowfall. Winter has finally wintered again, and it’s been fantastic so far. Let’s bring the rest of this one home!

Forecast discussion says the NWS obs at 7pm was 10.7”. We tried.

Is this actual heavy snow coming or sleet mixed in?

I mean, is there even one person in this sub who thinks New Englanders are good people who deserve two epically good things on the same day?

Just remember, Boston is jackpotting on this storm and the Patriots are about to punch their ticket to the Super Bowl.

NWS obs is up to 10.2” as of 5pm.

Daily climo report as of 4pm: Still need 2.2… SNOWFALL (IN) TODAY 9.8 R

At the end of the day, this event is likely going to make it into the Hall of Really Good in our local area but not the Hall of Fame. And that’s fine. It’s been awhile since we’ve even had something like this. Snowmageddon II will have to wait.

A large amount of our region will, but I’m beginning to question whether or not our 30+ year streak without 12” in a single day at the official observation site might actually somehow continue.

About to get into some lighter snow?

You could make a case for 2016 but that wasn’t region wide, only the southern parts got there.

When was our last big January snow? 1996? Has it been that long?

Yeah it filled back in. Decent radar returns as the precip gets closer to the radar.

By the time it gets here (if it does at all), we could have a ton of snow on the ground. I wouldn’t fret.

Now whether that mixing makes it another 50 miles NE with that batch is hopefully a different story.

Mixing. Correlation coefficient tells all.
