He presents this graph of the Texas coincidence economic index. It's a combination of four different metrics:
- nonfarm payroll employment
- average hours worked in manufacturing
- the unemployment rate
- wage and salary disbursements deflated by the consumer price index (U.S. city average)
You can't even see the effects of the drought there -- though the fact that it excludes nonfarm payrolls might matter a little. The Texas GDP is $1.207 T (2010), and $5 B (if that's accurate) would be 0.4% -- a setback to an economy, but certainly not a shock.
