Dust storms have proven deadly to motorists across the U.S. for years. Authorities say a dust storm last week reduced visibility to nearly zero on Interstate 70 in western Kansas.

Violent tornadoes and high winds decimated homes, wiped out schools and toppled semitractor-trailers as a monster storm that killed at least 32 people ripped its way across the central and southern U.

Unusually vicious and damaging weather across multiple U.S. states spawned violent tornadoes, blinding dust storms and fast-moving wildfires over the weekend, leaving at least 39 people dead. In the latest tally of the destruction,

Throughout the South and Midwest, residents and work crews were beginning to clean up Monday and survey the destruction after severe weather across seven states kicked up a devastating combination of wildfires,

According to the SPC: “The HIGH risk area almost always means a major severe weather outbreak is expected, with great coverage of severe weather and enhanced likelihood of extreme severe (i.e., violent tornadoes or extreme convective wind events over a large area).”

In these high-shear, low instability setups we can get isolated severe thunderstorms. Damaging winds and even the possibility of a brief, spin-up tornado will be the threats. Timing will be very important.
