Utah runs the world's largest remote-controlled cloud seeding effort

The Utah State Legislature put big money into cloud seeding this year to help mitigate drought impacts. The cloud seeding budget went from roughly $200,000 in 2022 to nearly $16 million.

There's been a lot of talk about missing NWS upper air obs in recent months, but not as much specifically about AK. Thanks to @alaskawx.bsky.social I have a discussion today about the increasingly concerning situation there, and why it impacts all of us. More: tinyurl.com/bdeebmn6
A high-impact weather weekend in store
Major coastal impacts for the East with serious flash flooding risks in the Southwest. Also, a deep dive into the state of the NWS upper air network in Alaska.

In the third SAR image you can also see trails of slower near-surface flow downwind of the volcanic islands.
Zoomed in image of the last SAR overpass in the original post using a color map with higher contrast. The small islands (black colors) leave behind small trails of lower wind speeds (cooler colors) as the mountainous terrain obstructs the near-surface wind, showing the extremely high resolution of these observations.

The pattern that supported Mitch in 1998 and Wilma in 2005 is eerily similar to today’s week two guidance.
CPC 8-14 day analogs for the 500 millibar pattern centered on October 20th. The top two are 10/30/98 and 10/20/05. Map shows anomalous ridging in red over Hudson Bay, and troughing in blue south of Nova Scotia and in the western US.

One day in the lab, we accidentally discovered that the spines of a cactus 🌵 straighten when exposed to fog. I was intrigued and so were my collaborators. How does this work and what can be gained from it? Here are some of the answers in our new preprint:

A hill I will die on is that the Palisades Fire was not “caused” by the person who lit the Lachman Fire. It was caused by systematic failure to prepare landscapes and communities to receive fires that will inevitably occur in a fire prone region in which 25 million people live.

A trio of cyclonic eddies in the Gulf of Mexico are creating record-high Ocean Heat Content values for the date. Absolutely something of importance during this part of hurricane season.

Highly unusual situation approaching western Colorado with the moisture from Hurricane Priscilla. Grand Junction has never had precipitable water over an inch (25mm) so late in the year, but looks like it will be near that level on both Fri & Sat. Six standard deviations above average! #cowx 1/2
Global Ensemble Forecast System mean precipitable water and 700-mb winds valid on Saturday morning, 11 October 2025. A big plume of moisture will be transported into the southwest US ahead of decaying Hurricane Priscilla. From https://schumacher.atmos.colostate.edu/weather/ens.php Standardized anomaly of precipitable water from the ECWMF ensemble mean on Saturday morning, 11 October 2025. It shows a broad swath of  greater than +3 standard deviations in the western US. From https://schumacher.atmos.colostate.edu/weather/ecmwf.php Ensemble forecast plume showing precipitable water at Grand Junction, Colorado in the members of the ECWMF ensemble. Values are predicted to be around 25-30 mm with high confidence on Friday 10 October through Saturday 11 October, far above the 90th percentile for the date.

Jerry's a top 1% in terms of its fast movement through the deep tropics. Its speed is knocking its circulation off kilter but it should organize as it slows and turns near the islands. Also, as Jerry would say, what's the deal with the weekend nor'easter?
Jerry Forms but Slow to Strengthen, Tropical Storm Watches Issued for the Northern Leeward Islands
Jerry forecast to pass near the northern Leeward Islands as a hurricane tomorrow and Friday but turn well east of the U.S.

Drought is climate change's biggest threat: If this winter is as dry as last winter, and no major reductions in use occur, Lake Powell by 2027 would have no storage left and “would have to be operated as a ‘run of river' facility” in which only the inflow from the river could be released downstream.
‘No One Comes Out of This Unscathed’: Experts Warn That Colorado River Use Needs Cutting Immediately - Inside Climate News
A new report finds that Lakes Mead and Powell, the nation’s largest reservoirs, could store just 9 percent of their combined capacity by the end of next summer.

CPC keeps the CAG TC risk going into late October.
CPC tropical cyclone potential next week (top) and Oct 22-28 (bottom). At least a 40% chance for development both weeks with the Central American after. Another Cabo Verde African wave storm could form behind Jerry.

Its verification time. As of 15z Today Oct 7th, Tropical Storm #Jerry has formed with 40 kt winds.

Pretty clear at this point the #ECMWF has struggled with this genesis case, possibly due to the same amped up gravity wave issues that have plagued the model in the tropics for some time.

Now that the data is backfilled, the deterministic AIFS did quite well with Typhoon Halong - it was the only model I track on my site that consistently depicted a quick recurve south of Japan:

Though warmth in the Caribbean Sea is not at 2023 or 2024 levels as of yesterday (5 October 2025), it's noticeably beyond what's been observed via area-wide sea surface temperatures (SSTs) in other years since 1982.
Line plots of area-averaged sea surface temperature in the Caribbean Sea as of October 5, 2025. Black shows the 1991-2020 average, red shows 2023, orange shows 2024, and blue shows 2025 (so far). An inset map depicts October 5th's map of anomalies, where the dashed box represents the averaging region used to make the line plot values. These are computed from NOAA's OISST dataset using Python.

Now up to 3500 acres and 35% contained. #TXwx #TuleFire
wxandbiscuits.bsky.social
The Tule Fire in Briscoe County, TX, is burning in an area with at least 130% of normal fuel loading. Not a good sign for the Southern Plains the next 6 months given that fires over 1000 acres are rare this time of year.
The Tule Fire is estimated by the Texas A&M Forest Service to be ~1500 acres and 0% contained as of 3:45 PM CT Saturday. It may be burning into the tricky terrain of Tule Canyon, where firefighting is much more difficult than the flatter Caprock/ag areas. Grass-cast shows dark blue areas have at least 130% of normal grass loading from an abnormally wet growing season. Large parts of TX and OK are reported to have well above average to exceptional grass loading that will likely lead to outbreaks of large wildfires this winter into next spring.
