Watching for flash drought
Could the Imminent U.S. Heat Wave Trigger a Flash Drought?

Excerpts

"It wasn't too long ago--in 2012--that a promising-looking spring 
morphed into a terrible summer for the U.S. Midwest. A long-term 
drought that began in late 2010 had intensified over the Southern 
Plains in 2011, punishing farmers and ranchers and facilitating the 
loss of roughly 10% of all trees in Texas.

"The real shocker was how quickly drought conditions took hold 
further north across the Midwest in the summer of 2012, leading to 
the most widespread U.S. drought conditions since the 1930s."

"While long-term drought can emerge simply through a lack of 
precipitation, a flash drought is closely linked to hot summer 
weather."

"At first, the landscape may not be particularly dry, in which case 
large amounts of water vapor flow from vegetation and soils into the 
scorching surface air (as is expected later this week). If the heat 
is strong and sustained enough, the landscape quickly dries out and a 
flash drought takes hold."
