Wow, big gains over the last two days. Almost wonder if the wind wasn't messing with algorithm. Now just 1% below the 52-year average.

Another weathergami on Monday:

Solid start. I'm probably closing in on an additional inch. Grass is completely covered now.

That's our bread and butter. Although I'm gonna have to call foul on the airport (actually the NWS office in Moon) being moved 20 miles south, since it already did better than probably 75-80% of the area with the last event. It doesn't need to be the jackpot for every event.

Good news on the Lake Erie ice front. Recent warmth has brought total ice coverage down to less than 25% of normal to date (4% coverage versus mean of 13% for the date). All of the lakes are running a little behind normal, as of yesterday's analysis.

Snow squall conditions possible tomorrow night, per NWS.

Only about an inch here this morning, but it's snowing very heavily now and rapidly accumulating. Wonder if we'll get a snow squall warning?

Thanks for the update, Don. As one might expect, a MASSIVE outbreak of "weathergamis" occurred yesterday (and undoubtedly today as well). I've been following this account for a while and this is, by far, the most I've seen.

Severe weather, including tornados, look possible as well.

Back on now, although mostly from PIT north now.

Like in Pittsburgh, Monday afternoon may be in the upper 20s but the high is likely to be near 60 degrees!

The progged temps aren’t factoring in the incredibly warm midnight highs that are likely in this regime, so probably way too low.

Februarys were a blowtorch, however. Very curious. Will be interesting to see if a similar theme plays out in 2026.

Wow, this is interesting how cold the ensuing Januarys were following the warmest Decembers. Some are forecasting a cold January this year as well.

Either way, a VERY respectable anomaly. From a historical standpoint, this could wind up warmer than any December prior to 2015 if PRISM is close. Not sure what's going on with recent Decembers. 3 of the past 4 were even warmer. So from a historical standpoint, EXTREMELY impressive, but from the vantage point of recent years, pretty ho-hum national anomaly. It doesn't appear to be data error, because the USCRN network suggests recent Decembers were even warmer than given by the nClimDiv numbers.

I bit the bullet and picked up a subscription for the PRISM estimates. It's estimating 2.76F through Christmas day, but we've been adding 0.5F per day lately. Extrapolating through yesterday, PRISM would probably have us up to ~+3.2F for the month to date.

Looks like January 29, 2022.

Not too shabby. I think this might wind up warmer than any December prior to 2015.

Updated PRISM here (through Christmas day). We've been tacking on 0.5F+/day during this Torchmas pattern. Probably around ~+3.2F once updated through yesterday.

Just worried with all the unhinged lunatics complaining about the Park's snowfall measurements, we won't start seeing them inflate the measurement to appease these people.

Has anyone audited the Central Park measurement for this storm? Wondering if they really had 4.3 inches. This commenter claims she measured 1.8 to 2.8 just west of the Park.

Wow, 66 tomorrow? Would be a new record for Dayton. Have to imagine at least a few breaks of sun occur tomorrow to get that warm.

The SPC has expanded the Day 3 marginal risk for severe weather to include portions of the Pittsburgh region. Something to keep an eye out for on Sunday.

Big warmup out there. Car thermometer was reading up to 50 on the hills, but still 43 in narrow valleys.
