QuadWeather now computes high-resolution (750-m) derived fields, the coolest of which is a hail size algorithm validated on events from the 2025 severe weather season. The application is truly research-grade software in the browser.

The high reflectivity associated with the massive Kankakee hailstones on 10 March formed 7–8 km above the surface and reached the ground within ~10 minutes.

It was just pointed out to me that this system is actually within range of Alaskan radar! Much like a TC, there is well-defined spiral banding with the strongest winds in a relatively tight RMW. Unlike a TC though, the precipitation here is…snow.

A lot of people (including myself!) tend to scoff at the notion that these Mediterranean storms can be something other than (sub)tropical. However, from time to time, the atmosphere reminds us that classifying convective lows is hard! Take a look at this polar low near Alaska:

Interesting disturbance in the Mediterranean Sea drifting towards Libya's Gulf of Sidra. It doesn't look particularly frontal, and there's some persistent convection near the center, although not particularly deep. It probably isn't too far off from being a subtropical storm.

FYI you can make radar.quadweather.com look however you want by making a classic Mapbox style and reflectivity color table. Cool look at severe storms moving through St. Louis.

Only one Severe Thunderstorm Warning in southern Missouri at the moment, but that will change rapidly as the front tracks eastward. SPC's Wind Outlook and MRMS reflectivity overlaid.

@nplareau Road 203 Fire near the KLNX radar. Thanks for pointing out, neat data

Fires, plumes, and wind shifts. Stay clear of the south flank of these fires, which will open up as the front surges through.

@AtlanticWx @NWS_BaltWash @capitalweather Radar at the time with storm cut in half in the 3D render. The top of the storm is also cut off because it was tall and close to the KLWX radar.
