Recorded and now available, in case you missed it. Since this session ended, the NWS has now issued an Extreme Heat Warning for most or all of coastal SoCal for Wednesday (yes, tomorrow will be even worse) for the genuinely dangerous combination of extreme humidity plus heat.

July 10, 2026 - Daniel Swain - June was mostly warmer than average in California, but without exceptional heat and with robust coastal marine layer; large and destructive wildfires explode across Southern Rockies amid strong winds and extreme drought June was a relatively warm month across much of the western U.S. compared to long-term averages, though record warmth was limited to the #

Okay, folks: The big El Niño update is now out on Weather West! This sure looks like it's going to be a dramatic year from a global climate perspective, and there are major implications for extreme events (across California, the U.S. West, & well beyond).

Special update: Rising odds of a strong-to-historic El Niño event in 2026, with growing likelihood of significant regional-to-global scale impacts - Weather West

June 11, 2026 - Daniel Swain - A quick refresher: What is El Niño and how can it affect global weather patterns? El Niño is the warm phase of the El Niño-Southern Oscillation (ENSO), a semi-regular recurring cycle that transfers vast amounts of heat and momentum from the tropical Pacific to the global atmosphere. It is triggered every 3–7 years when the #

Of all the harm this administration has done to US science, today's proposed changes to the way federal grants are awarded and administered is the most damaging yet. The text of the federal register document is impenetrably tedious by design, so here's an excellent summary of what it says.

Incredibly, even *more* locations across U.S. are today experiencing their warmest March temperatures on record--many by a wide margin, with some even breaking April records. This includes most or all of: AZ, UT, CO, NM, WY, NE, KS, MO, IA, plus portions of many other states. 🫠

For a Good time Dont call

Similarly, my Weather West post from earlier is also still on track. This will be a "double peaked" heat event, with "lesser" peak centered over Southern California today before a minor pullback this weekend. Then, next week, the main event begins...

March 11, 2026 - Daniel Swain - "Winter" 2025-2026 warmest on record across most of Western U.S., including SoCal & Sierra Nevada Well, now it's official: Winter (Dec-Feb) 2025-2026 was the warmest on record across the majority of the American West, and a top-3 warmest winter nearly everywhere that it didn't quite cinch the record. That includes nearly all of the Colorado #

Every day can be international women’s day if you just maintain an extremely fixed delusion about how things are going

Remarkable and widespread record warmth today across the Southwest. In fact, some locations in southern CA and southern AZ are not just breaking daily records, but also monthly February records--with current temperatures well into 90s and approaching 100F in some spots. #CAwx #AZwx

we need to resurrect public sphere convo in that the us mexico border wall is an unprecedented ecocide. the voices didn’t go anywhere, the research is there (not that research is even needed to draw the common sense conclusion that a border wall across an entire continent is fucked)

New on Weather West: If we're going to see an extremely moist & warm #AtmosphericRiver this wk in NorCal that will bring rain atop recent heavy snow, why is major flooding *not* expected? It a story of (lacking) storm dynamics & snowpack resilience. #CAwx

Following a whiplash transition from record warmth to very heavy mountain snowfall in California, yet another swing back toward anomalous warmth (first damp, then dry) - Weather West

A remarkable snowy interlude during what has thus far been a record warm winter: Disruptive, and even deadly, in the Sierra Nevada Last week's snowfall in the Sierra Nevada--and also at much lower elevations, for the first time this season, into even the lower foothills and Coast Ranges--marked a dramatic shift from a nearly 40-day

Following last week's heavy & disruptive Sierra Nevada snowfall, an extremely warm atmospheric river will cause substantial rain to fall atop snowpack even at high elevations this week. *However,* widespread serious flooding is *not* expected...for now. Why? [Thread] #CAwx
