Drill bit tornado in SD!

HUGE supercell in SD up to around 60,000ft KFT!

Notice how debris goes vertical at corner flow! Looks like this tornado’s wind field was a bit larger than the condensation funnel suggests!

#SRRadarLoop of the Valley View EF3 tornado from May 25th last year. This tornado tracked for 48 miles and had a width of perhaps 2 miles wide based on recent reanalysis.

Big tornado near Dixon SD!

Large cone tornado near Burke SD!

Tornado moved fairly slow over/near this farmstead near Bonesteel SD.

Strong tornado near Bonesteel SD! From Ryan Scholl!

Amazing shelf cloud ahead of this cold pool!

Extremely intense MCS over NW Iowa. KFSD 0.5° tilt scanning >90-105 mph winds in the lowest 1000ft ARL. A PWS recorded a 93 mph gust as the RIJ was intensifying. I have no doubt this is producing insane straight line winds.

Animation of the intense tornado outbreak that occurred back on May 16th of this year across the Midwest including the infamous London, Kentucky EF4.

#SRRadarLoop of the Jasper-Cordova EF4 tornado from April 27th 2011. This tornado tracked for 116 miles and at one point had a satellite. This was one of the longest tornado paths that day!

Thermal wind balance is an incredibly important concept in meteorology. I have put together an animation to explain how it works visually.
