Factors Favorable For Warm Season / Convective Flash Flooding

• Strong low-level jet (>30 (20) kts) / θe advection.

• Weak mid-level winds / weak mid-level shear.

• Deep warm cloud layer (greater than 3 km).

• Moderate – high "skinny" CAPE south of the heavy rain (NCAPE < 0.10).

• Precipitable Water > 130 percent of normal.

• Weak short-wave trof upstream of heavy rain.

• Upper-level divergence / jet entrance region.
