Enhanced Fujita Scale (NOAA) Another important milestone is the implementation of dual-polarization radar, between 2011 and 2013, which gives forecasters and researchers a much higher-resolution view of thunderstorms associated areas of rotation.

Abstract: The 2001 Independence, Iowa tornado: Issues associated with non-supercell tornadogenesis far from the radar (21st Conf. on Severe Local Storms and 19th Conf. on Weather Analysis and Forecasting/15th Conf. on Numerical Weather Prediction)...
The Nashville tornado was one of scores to occur in the central U.S. from May 6 to May 11, easily the most active tornado days this year as severe weather seasoncomes to a peak(though this week is no slouch).Preliminary data collected by the Iowa Environmental Mesonetshows that the Natio...

">#Iowa: National Weather Service: #TORNADO WARNING in this area until 4:30 PM CDT. Take shelter now in a basement or an interior room on the lowest floor of a sturdy building. If you are outdoors, in a mobile home, or in a vehicle, move to the closest substantial shelter and prote...
“I would guess there wasn’t a clear signature on radar for a warning in 2005,” said Gass, who was not there at the time. The fast-moving storm prompted warnings for residents to take shelter, but few people have basements in the area. ...

The radar loop to the right is from the Derecho that brought hurricane force straight-line winds across Iowa and Illinois in August of 2020. Numerous QLCS tornadoes occurred across Illinois and portions of southern Wisconsin that afternoon. ...
Fujita Scale, five categories of wind speed that are estimated the damage left behond (these are not wind speed measurements, since most wind-speed measuring devices are destroyed during tornadoes, and since the tornadoes die out so quickly, Doppler radar wind measurements are not usually done)....
