When I was working on today's weather newsletter, I was struck by how today's record low of -3 is so starkly different than yesterday's and tomorrow's (10 and 11, respectively). And then I noticed that year, 1880, had several *more* record cold days at this time — five out of six, in fact! (1/2)

Expect this list to grow: Three of the top 5 deadliest heat waves in world history have been in Europe in the past five years. "Mitigating further global warming can reduce heat mortality, but mass mortality events remain plausible at near-future temperatures despite current adaptations to heat."

Local news outlet had this as the forecast for today. It is not slushy, and it certainly has not looked like it was going to be slushy for some time.
If you're going to have weather, have a meteorologist.

A massive lake effect snow event impacted Buffalo, New York. Over the course of 3 days, bands from Lake Erie produced snowfall rates up to 3-6" per hour. Totals in many areas peaked at over five feet. Tragically, thirteen people were killed.

I really wonder if our waste company actually processes recycling. One neighbor always puts garbage in his recycling bin (and it's obvious), and another neighbor put a plant in their bin this week.

Some of the country's highest home insurance prices are in the central U.S., a region generally considered to be protected from climate-driven disasters such as wildfires and hurricanes.
Why home insurance is unaffordable, even in places without wildfires or hurricanes

Did the last mow of the season this morning. Glad I don't have to mess around with gas or oil.

What was the weather like on your birthday? Now you can find out!
During the shutdown, I forced myself to stay agile in data science tech, like AWS, Google, and Open AI.
I made a notebook that gets weather for the day/location of your birth, using multiple NOAA sources.

This cold outbreak was also impressive in how far south it pushed, even to #Miami, FL. The Miami International Airport #KMIA set its first record low (49°F) in more than a decade!
Between the last two record lows (11/2/14 to 11/11/25), there have been *97 new record highs* set at the airport. #FLwx

An Armistice Day storm raged across the Great Lakes Region and the Upper Midwest. A blizzard left 49 dead in Minnesota, and gales on Lake Michigan caused shipwrecks, resulting in another 59 deaths. Up to 17" of snow fell in Iowa.

Still needs some work, but I'm mostly there getting Google Sheets to import the WPC list of forecast near/new records and assigning the lat/lon to the station codes to export as a CSV.
I'll confess that I've used ChatGPT to work through the vibe coding.

Hey @akrherz.bsky.social, any previous instances of waterspouts mentioned in the same product as snow? I swear I've seen it, but I could be wrong.
WOW. This might be a first – a formal special marine warning for SNOWSPOUTS, or winter waterspouts.
These are the same as warm-season waterspouts, but they're forming beneath snow squalls.
It's because of the EXTREME contrast between the warm lake waters and frigid air above!
