Wow, they need to expand that y-axis. We're not seeing the full ensemble mean spread for late summer because it's cutoff by the current y-axis. Some of those individual model runs must be at or near BOE criteria as well.

CFSv2 forecasting a "blue ocean event" for this summer:

Same story in the District, where the 10-year period ending 12/31/2025 narrowly beat the 10-year period 12/31/2024. I wonder if 2017-2026 will outdo 2016-2025 and 2015-2024. Will be interesting to see. At least 22.2" is needed to avoid a new record - a very solid tally for the District.

While we watch the digital snowfall totals pile up and hope some of that comes into fruition, I thought it would be a good time to take a look back at the historic 10-year snow drought. Very impressive numbers, and we will need some fairly hefty snowfall in 2026 just to keep pace - especially at Baltimore, where nearly three feet (35.1") would need to fall just to prevent 2017-2026 from being even less snowy than 2016-2025. To put that into perspective, only 18 calendar years at Baltimore have seen more than 35.1" of snow!

As our historical snow drought enters yet another year, I thought I'd take a look at the numbers at Philadelphia. Very impressive, with the most recent 10 years checking in as the least snowy on record. 2026 will need at least 27.5" of snow during the calendar year to avoid a new futility record. That's a respectable tally, so it's possible that 2017-2026 could be even less snowy than 2016-2025. Stay tuned!

The post was referring to CONUS temperatures. While Alaska is part of the US, Canada is a separate country and has not, in fact, been annexed as of 1/2/2026. If we are going to include other countries, might as well tack on Mexico, which has been scorching. Or just do the entire Northern Hemisphere, which has been consistently running more than 1C above the 1981-2010 mean. http://www.karstenhaustein.com/reanalysis/gfs0p5/ANOM2m_mollw/ANOM2m_f144_mollw.png

Ice advancing quickly now. Erie more than 1/4 ice covered, as of today, which is 9% higher than the 53-year mean. The thaw next week should trim that back.

Not sure if it's possible to embed but here's some lightning earlier in McKean Township, just south of Erie. https://www.facebook.com/reel/1873659720188526

Thundersnow in northwest Pennsylvania and southwest New York.

Didn't measure, but eyeballing looks like at least 2, maybe 3 inches here. Squall line showing up on radar south of Cleveland.
