Since I see it making the rounds again: Sonic Anemometers are *very* error prone when particles are in the air (snow,dust,smoke,mist etc.).
The ASOS's Vaisala WMT700 series internal QC is particularly bad at spike rejection in these environments.
So if you see AUTO +SN 24G104KT, throw it out.

One of the primary tools we use to predict flash floods is the NSSL's Multi-Radar/Multi-Sensor System. "I’ve zero doubt NWS forecasters were leveraging that tool that evening to issue flash flood warnings. NSSL and associated projects are slated for elimination in NOAA’s proposed 2026 budget."
It's been a terrible and tragic weekend from tropically-infused floods, including the heartbreaking events in Texas Hill Country. In today's newsletter, I revisit the weather causes and detail how National Weather Servive forecasters performed admirably despite political headwinds. ⬇️
Trying to Make Sense of the Unspeakable Texas Tragedy
Catastrophic flooding in the Texas Hill Country over the holiday weekend is one of the deadliest in modern memory. How did it happen?

Below is a series of posts explaining the difference between a wake low and a Mesoscale Convective Vortex (MCV) and a Rear Inflow Jet (RIJ) and how this exceptional storm system over North Dakota came to be last night. This radar loop is awesome by the way.
Discrete tornado-producing supercells, derecho with a textbook bookend vortex & rear inflow jet development, MCS-supercell mergers... this is one of the most meteorologically impressive radar loops I've put together.

Here is the launch via GOES-16. Didn't notice any clear signature down-range in southwest atlantic. Looked at Key West, Puerto Rico, and the few cuban radars as well and nothing.

Do you use @radarscope.bsky.social and have a Tier 1 or 2 subscription? I made some custom color tables you can download and import.

Reminder that Sonic anemometers are absolute CRAP during wind events with flying particles. Here is a outflow boundary full of dust in North Dakota tonight. Sonic's are recording gusts to "70+ mph" while the mesonet with all mechanical propeller anemometers are topping out in the 40s +50s.
