Since Trump is making fun of vegans eating vegan food today, I thought I'd share a pic of my meal at a vegan restaurant. Yes, it was yummy.

Our dear friend Tiberius passed today, a few days shy of his 16th birthday. He was a lover boy true and through, a cat of such quality he deserved far more years.

Alas, we won't pile up the snow like my friends in Ithaca or Boston will, but we are S+/BS here in northwest Boulder for the moment.

Here is an animation from The Weather Company's GRAF model, 18 UTC initial time today. GRAF is based on the NCAR MPAS model but largely runs on GPUs. Lots of ice.

AIFS looks a touch more phased, fwiw. But point taken. On behalf of all my colleagues in Atlanta hoping to fly to AMS A on Sunday, I'm watching there closely, and it's a squeaker, ZR or R+

No Kings, Boulder, CO from the far periphery (we arrived late). Good energy, estimate a bigger crowd than the June rally.

This sort of ad amuses me, in that the picture is clearly clickbait and utterly related to the product. Sex sells.

So USA needs a new political party. Here's the Finley party platform. 1. Just walk away from yappy loudmouths. 2. Prioritize play over everything. 3. Love your peeps, always. 4. More walks. 5. Kisses! 6. Eating cat poo optional.

It's struck me that the rate of flow of water through a drip coffee maker resembles a unit hydrograph. Google Gemini tells me I'm full of it. www.nohrsc.noaa.gov/technology/g...

More bad car design. Who ever said "Why don't you paint a third of the back window black so I can't see behind me very well?"

It used to be cars had bumpers that the government regulated could stand a 5 MPH bump. But this was big government run amok, so now we have cars with "bumpers" that require enormous repair with the slightest tap

Dangerously tiny windows is the rage in new car design. I'd welcome cars with good visibility, which strikes me as a safety issue.

Saw this pic and thought of the old military aphorism "salute the office, not the man." (would *hate* to be the woman in the pic).

Aside from the obvious constitutional issues, the prognosticator in me has to laugh at the assertion that Trump thinks he would have a chance of winning.

Too much red. Winter doesn't feel great walking the young pup 6 times a day, but it's still part of the natural balance.

10 days till this Scottish collie joins our family. We had a rough collie till a month ago; a wonderful dog, but we worried about the genetics of the breed. So many breeders care about looks, not health. This collie is from a breeder cares about health over breed standards.

A new Scottish collie puppy will join our family in two weeks, and we are naming him Finley. This happens to mean "courageous one" in Scottish, but it also happens to be the name of the meteorologist who issued the first successful tornado forecasts, JP Finley. Consider this homage to NOAA SPC.

GRAF is The Weather Company's version of the NCAR MPAS model. I'm working to get usable probabilistic precipitation from a single integration of the model via deep learning. A work in progress, but encouraging. Feedback and discussion from experts welcome.
