The July 26, 2012 was reasonably similar to other warm season major squall line events.

• Large CAPE downstream from the line (greater than 1500 J/kg).
• Strong shear, especially from 0-3 and 0-6 km (greater than 30 kts)
• Modest mid-level forcing / height falls (less than 50 m in 12 hours).
• Modest storm relative flow at the equillibrium level (40 kts or less).
• These factors have been combined to produce an “alert” for a major warm season convective squall line in the WFO BGM severe weather checklist.
