Imelda and Humberto are churning only about 580 miles from each other tonight. Only 9 other named storms have ever come as close or closer in the Atlantic in the satellite era (since 1966). The last occurrence was Philippe and Rina around this time in 2023.

Preview of this afternoon/evenings activity. #AZWX #TUSwx #SierraVistaAZ #FtHuachuca.

SPC RAP valid +6 holds H5 heights at 594 dam, maybe holding subsidence but despite that, instability is enough to overcome the CAP along our ranges with orographic lift. TCU's & a couple CB's w/ strikes in the AO already.

I don't recall seeing this much instability all season - coupled with these theataE & PWAT numbers. Subsidence & CINH diminishing now as well! #AZwx #Monsoon2025

My first to hit town in 5 yrs here.

I was sad the past few days b/c I could not find this delightful profile on X anymore. Behold - they are alive and well here on Blue Sky. #ID4 #independenceday

Brief time lapse of developing thunderstorm over the Huachuca mountains. #azwx #monsoon

Quick time lapse of nearby downburst & outflow. East of Canyon Vista Hosp; kicking up some dust. Got the drone in the hangar just in time to avoid the gusts. #BLDU #AZwx #Monsoon2025 #TUSwx

Broke out the drone for some pics of the moisture axis finally shifting a bit west & north. #AZwx #TUSwx #Arizona #Monsoon2025 #ArizonaWeather

Yesterday afternoon, a severe thunderstorm in northern Colorado dropped a swath of hail that could be seen by GOES-18.
Hail is in the darker red color.

Another round of scary dark clouds 🤠#AZwx

Which hurricane models should you trust in 2025? » Yale Climate Connections How the models did last year, and why you should pay the most heed to the National Hurricane Center forecast.

For hurricane nerds only: my annual roundup of which models did the best. The European and GFS models were the top track models in 2024, with the GFS making better four- and five-day forecasts. The official NHC forecast was tough to beat. yaleclimateconnections.org/2025/05/whic...

Mountain wave & stacked lenticular day across Southeastern AZ high country! #Arizona #SierraVistaAZ #lenticular #turbulence #avweather #aviationwx #AZwx #TUSwx

Haha. Thought so. 😁

One of the books that helped guide my childhood passion into a career where work doesn't ever really feel like work. #NCwx #AZwx #wxtwitter Miles gets his own copy, I try to keep my copy from Dad in decent shape (circa. 1998).

Looks like a city of SV prescribed burn. Was concerned b/c I didn't see on the state AZDEQ prescribed burn page for today.

Fire near/at landfill just east of Canyon Vista Hospital in Sierra Vista, AZ. Dense smoke - appears on radar as light precipitation return. #azwx #smoke #firewx #sierravistaaz #forthuachuca
