@evan_bentley Will the conditional hail/wind/tornado probability products from the current HREF be available with the REFS model, and will they keep the current HREF viewer website and just display REFS data in it?

Looking from South of Columbia, MO a few minutes ago.

The enhancement of this boundary is really evident in 3hr surface temperature change analysis. Cool lake breeze CAA and warm-sector WAA clashing in N. IL is enhancing low-level convergence and low-level frontogenesis. #ILwx

@DualDoppler The sharp reflectivity gradient that close to the radar is very telling too.

🧵 How drones are changing tornado science (and your future warnings):
1/ 🚁 NSSL and @CIWRO_ are using uncrewed aerial systems (UAS) to fly into areas too dangerous for humans, gathering pressure, temperature, wind data and more... right where tornadoes form.

🚨 Forecasters LOVE faster radar updates from Phased Array Radar!

Inside @NOAA's Hazardous Weather Testbed, we’re testing dual-pol PAR data to see how quick scans & better detail help improve warnings.

⚡ Fast updates = smarter alerts!

Lived here my whole life. These signs give me so much anxiety 😂

A little timelapse from earlier. Watch the occlusion take place, and notice the remnant mesocyclone moving right once the outer arm starts to come overhead :)

Not my video but a friend on Facebook. Tornado on the ground North of Potosi. @ryanhallyall @NWSStLouis @fox2ch @ReedTimmerUSA

[Calvin Thomas (Doppler) @DopplerWx]

Well, that was cool. Another good chase for the books :)
