To really get the AZ's monsoon, who better to appreciate it with than stormchasers? With @stormchasertang.bsky.social etc., I got to feel not just the monsoon's immensity but also its spottiness and reticence. And I took the least impressive photo for my article, by far. @azcentral.com

Storm chasers capture thrill, frustration of erratic Arizona monsoon | Exclusive

This year, super El Niño, reduced weather balloons, dust and climate change add to the challenges of storm chasing in Arizona.

The cat is officially out of the bag. I promised a consequential first, here it is! On (or around) October 6th, for the first time in its 20+ year history, the SPC Mesoanalysis will be available to the field in real time via NCEP NOMADS. Oh, and it’s in NetCDF, not GRIB.

My crankiest belief is that we are now being sold on solutions to problems which only exist because we've let others convince us they exist. That is what "innovation" seems to be in 2025. There's a level of introspection that's just not happening these days re: what actually needs to bother us.

I have a rough hypothesis that patterns favorable for plentiful California precipitation, Plains tornadoes, and I-95 snowstorms tend to cluster together over multiyear timescales. Occam's Razor says to look at the first EOF of NH 500mb variability: the NAO.

Few people even know about this; when people are asked in surveys how child mortality has changed the majority says it has stagnated or increased. If you consider that many don't know about humanity's biggest achievement, then it's not surprising that many are so pessimistic about our future.

Some intense precip gradients across the San Francisco Bay Area. Between San Rafael and Richmond (a 20-min drive across a bridge) the 48hr rain totals go from 7" to 0.7". Rain shadowed areas near/east of Mt. Diablo and in the Santa Clara Valley have generally received < a tenth of a inch.

The westerly wind burst earlier in the month was pretty strong and is worth a further dive into the data/better analysis. Quick glance at Reanalysis daily data in Nov, for the equatorial 850mb zonal wind anomaly at 120°W since 1950, shows it was the strongest since the 1997 and 1998 November events.

All daily 850mb zonal wind anomalies in November since 1950 in R1 for 0° and 120°W. Early 2024 was the strongest since 1997 and 1998.

I think this could be a nice way to find the dendritic growth zone characteristics that winter forecasters look for (depth, omega, and RH) all wrapped up into one number. I can publish the code to calculate this on GFS grids if there's interest.

I'm not sure it was "obviously" going to be a blowout. First off, there's an incumbent disadvantage here where many people are seeking to leave the model of "big tech company controlling content distribution via algorithms on large platforms" and more focused on smaller niche communities 1/2

In June Elon posted this graph of the rate of likes on X. It doesn't have a unit on the y axis, but it's plausible to assume that it's events/sec. If that is true, X in June was handling about 20k likes/sec. For comparison, Bluesky is now handling about 700 likes/sec during the busy part of the day.

A graph showing the rate of likes on X over the course of a couple of hours on 12 June 2024. It fluctuates between about 17k and 20k; the y axis doesn't have a unit. A second line shows a comparison to the prior week, which is slightly lower. There are strange unexplained spikes on the hour every hour.

A graph showing the rate of various types of events on Bluesky over the last day. At peak there are about 800 follow events and 700 like events per second (note the likes are scaled down by a factor of 5; the right-hand y axis is for likes).

Update: La Ceiba, Honduras, now reporting over 34 inches of total rainfall from #Sara. As pointed out by @agnes1972.bsky.social earlier, that matches their rain total from 1998's Hurricane Mitch. With rain rates of 2-3.5 inches an hour, they'll crush their Mitch total.

The cool thing about Bluesky is the technical people are active (& hence dogfooding!) on the platform and transparent about the algorithms involved. Emphasis here is on open, extensible ecosystems rather than closed ones that we are used to on more established platforms.

From a net human impact perspective, the latest guidance for future TC Sara are concerning. Honduras has a rough history w/ hurricanes & the latest GFS shows a 5-day rainfall total of 1242 mm, or 48 inches, over parts of its north coast. This would have catastrophic consequences.
